Inlet/Outlet Chemical Isolation OR OR Inlet Protection Designed to react within milliseconds of detecting an explosion, a chemical isolation system can be installed in either inlet and/or outlet ducting. The chemical isolation system creates a chemical barrier that suppresses the explosion within the ducting, reduces the propagation of flame through the ducting and minimizes pressure increases within connected process equipment. Vertical Plenum A plenum that is bolted to the dirty air section of the collector. The explosion vent is mounted to the top of the plenum which effectively transitions the pressure and flame fronts from a horizontal to a vertical configuration. A vertical configuration make it possible to explosion vent through a roof and/or direct the pressure and flame fronts to a safe location as outlined in NFPA standards. In most cases, ducting and weather hoods are required to be compliant with NFPA standards to protect the explosion vents from the elements and other debris. Access panels are provided on the ducting so that easy inspection and/or replacement of the explosion vent is made possible without removing the ducting and weather hood. CHEMICAL ISOLATION EXPLOSION VENT DETECT & SUPPRESS AND MORE Explosion Venting Sequence 1 2 3 4 Fast-Acting Valve Designed to close within milliseconds of detecting an explosion, the fast-acting valve installs in either inlet and/or outlet ducting. The fast-acting valve creates a mechanical barrier within the ducting, which effectively isolates pressure and flame fronts (from either direction) from being able to propagate further through the process. Blast Plate A Blast Plate is a deflector mounted directly in front the explosion relief area. The deflector is designed to restrict the flame length ejected from the collector in the event of an explosion. For vessels that are not greater than 706 cubic feet, the deflector is designed to reduce the axial (front- centerline) safe distance by 50 percent.

Flameless Vent Designed to install over a standard explosion vent, the “FlamQuench SQ” extinguishes the flame front exiting the vented area not allowing it to exit the device. This allows conventional venting to be accomplished indoors where it could otherwise endanger personnel and/or ignite secondary explosions. Chemical Suppression Designed to react within milliseconds of detecting an explosion, a chemical suppression system is installed in the collectors dirty air section. The chemical suppression system prevents expanding a deflagration by releasing a chemical agent. This system is often used in order to put combustible dust collectors inside the factory where you can’t vent to the outside. Explosion Vent Designed to be the “weak” link of the vessel, explosion vents open when predetermined pressures are reached inside the dust collector allowing the overpressure and flame fronts to exit to a safe area. Explosion vents minimize damage to the dust collector caused by overpressure created by a deflagration. Camfil APC’s standard explosion vents are ATEX certified and NFPA compliant. The purpose of the Stinger is to prevent a deflagration (explosion) that could occur in the dust collector from traveling back down the inlet pipe back into the workspace/process. The iSMF has been proven to isolate the downstream equipment from the progres- sion of a flame front during an explosion. The Farr Gold Series® dust collector with an integrated Safety Monitoring Filter allows you to recirculate exhaust air back into the work space when your dust is explosive. The key advantage of this device is that it prevents the transmission of explosive dust (fuel) from the collector. Integrated Safety Monitoring Filter Detect and Suppress These systems protect the dust collector from ignition sources such as sparks or embers. It detects them and activates a suppression system that extinguishes them before they reach the collector.

Powder & Bulk Solids6 Editor’sChoice August2014 Mercury Intrusion Porosimeters Provide Advanced Performance and Safety In addition to offering speed, accu- racy, and a wide measurement range, mercury porosimetry also permits the calculation of numerous sample prop- erties such as pore size distributions, total pore volume, total pore surface area, median pore diameter, and sample densities (bulk and skeletal). Micromeritics’ AutoPore V Series mercury porosimeters can determine a broader pore size distribution more quickly and accurately than other methods. These instruments also include enhanced safety features and offer new data reduction and reporting choices that provide more information about pore geometry and fluid transport characteristics. The AutoPore V is available in two models to best match the require- ments of quality assurance and research labs. The AutoPore V 9620 has a pore size range of 500 to 0.003 micrometers with two high-pres- sure (60,000 psia maximum pressure) and four low-pressure analysis ports. The AutoPore V 9605 contains two high-pressure (33,000 psia maximum pressure) plus four low-pressure analysis ports measuring pore sizes from 500 down to 0.005 micrometers. Micromeritics Instrument Corp., Norcross, GA 770-709-7108 www.micromeritics.com Patented Bulk Bag Material Conditioner Discharging bulk bags containing material that has solidified, hardened, or agglomerated can cause serious operational bottlenecks. Conditioning and emptying bulk bags can be dangerous if the proper equipment is not utilized. This patented system utilizes hydraulically actuated, heavy wall tubular steel pivoting conditioning arms. Each conditioning arm features “v-shaped” tubular steel breaker profiles that safely and efficiently return solidified materials to a free-flowing state. The unit features a proprietary automated control package that eliminates operator variability and increases productivity. A powered rotary lift table allows complete material conditioning of the bulk bag on all sides, and top to bottom. The unit features an ultra-compact footprint and machine guarding for operator safety. Material Transfer & Storage Inc., Allegan, MI 800-836-7068 www.materialtransfer.com Silo Weight Monitoring and Control Scale-Tron Inc. announces a major upgrade of the SiloWeigh. Net inventory management and control system that moni- tors the weight of material in silos or vessels located across a very wide area. The information can be used to predict when deliveries will be necessary, even if the user is not aware of it, and allow appropriate action to be taken. For example, deliveries for the next day can be scheduled rather than react- ing to urgent phone calls. In addition, the system is claimed to eliminate shutdowns due to empty silos as well as overfill and its environmental consequences. Temperature compensated bolt-on strain-gauge sensors on the vessel’s legs or skirt send data via a digital transmitter at each vessel to the local area computer network, where graphical displays can be viewed on any computer. An overview shows all silos at the location and individual trend graphs can show the usage and refill patterns on any silo. Data is also transmitted via the Internet or, when Internet is not available, the cellular radio network, to the SiloWeigh.Net main database. This database allows data retrieval via a secure Internet site to show levels in all silos as well as trend graphs and alarm logs. Scale-Tron Inc., St. Laurent, QC, Canada 514-940-0337 www.siloweigh.net Ultra-Heavy-Duty Bulk Bag Filling System This new ultra-heavy-duty bulk bag fill- ing system palletizes and fills bulk bags with filter cake, aggregates, metal powders, abrasive minerals, dry chemical additives, and other difficult-to-handle bulk materials. The system integrates a Swing-Down bulk bag filler with a Flexicon pallet dispenser and powered chain conveyor, allowing safe, high-capacity filling of bulk bags of all popular sizes, including bags with wide- diameter spouts for passage of irregular materials. When a filling cycle is initiated by push button or contact closure, pallet dispenser forks lower the stack of pallets onto the chain conveyor, withdraw from the bottom pallet, and raise the remaining pallets, allowing the conveyor equipped with photoelectric eyes to move the dispensed pallet into position below the filling station. The bag connection frame of the Swing-Down fill head lowers and then pivots to a vertical position, allowing an operator at floor level to safely and quickly attach bag straps to automated latches, slide the bag spout over a wide-diameter inflatable spout seal, and press a spout seal inflation button. Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com Dual-Use Packaging System PDC International Corp., a world leader in the development and manufacture of shrink sleeve applica- tors and sleeve labeling systems, has introduced the 65 Series Shrinksealer. The newly re-engineered 65 Series was developed for continuous production environments. The equipment is ideally suited for shrink sleeve labeling, which involves full-height body sleeve labels with primary graphics. Used this way, the sleeve label can extend over the cap, with a horizontal perforation for tamper evidence on jars, bottles, and other containers. The machinery also performs tamper evident banding around the upper portion of a container and its closure, and applies full-height safety seals for vitamins and similar products. The machine operates at 50 to 175 cpm (containers per minute) with maximum speeds dependent on package dimensions. Sleeve diameter range is .375 to 3.25 in. Sleeve height range is .625 to 8 in.

8 August2014 IndustryInsight P Understanding the Long-Term Value of Dust Collection System Investments Travis Haynam trahay@uasinc.com Performing a lifecycle cost analysis is often an over- looked step in evaluating the purchase of a dust col- lection system. Too often, focus is given only to the initial purchase price of the equipment versus deter- mining the ongoing expenses associated with operat- ing and maintaining the system. Perhaps the reason for this approach is that many companies do not com- pletely understand the relationship between proper dust collection system design and configuration or its impact on operational costs. Many of those initial design decisions and configuration choices make the difference between an effective solution which is a sound return on investment or an inefficient system that drives up operational expenses. If not properly designed, the expenses to operate and maintain a poorly configured system will rapidly exceed the initial purchase price. The most expensive aspect of the dust collection system is the energy re- quired to operate the air moving device. Therefore, investments that minimize the horsepower requirement, such as reducing the required airflow volume and operating static pressure, will yield significant long-term savings. Some steps that will decrease the power requirement include having favorable inlet and outlet conditions or utilizing an airfoil fan wheel to allow the blower to op- erate more efficiently. Incorporating variable frequency drives (VFDs) is an ad- ditional investment that can significantly reduce the blower operating expense up to 30%. Implementing poor duct design practices or selecting less than ideal duct ma- terials will also negatively impact operating costs. For example, choosing to use long sections of spiral duct or flex duct versus smooth duct may save money on the initial material cost but long term, the additional friction added to the system will increase the static pressure loss requiring additional horsepower to maintain the desired performance. Upgrades to the hood design such as a flanged or bell mouth hood will result in improved contaminant capture while reducing system energy requirements. Most dust collection systems utilize a reverse pulse jet arrangement to clean filters and maintain system operating pressure. The associated energy costs of these compressed air systems are another important cost to consider. Taking steps to minimize cleaning frequency or choosing equipment which is more effective per cleaning cycle are essential for controlling ongoing costs. Incorporating an on-demand pressure controller that only cleans the filters as necessary is also a sound investment that can further reduce longer term oper- ating expenses. Choosing filter technology such as nanofiber that incorporates a surface loading layer which improves the effectiveness of a cleaning cycle will decrease the cleaning cycle frequency and lower maintenance costs. Considering the lifecycle costs of a dust collection system investment is es- sential in order to realize the full system value and maximize return on invest- ment. Working with specialists within the industry who understand the impact design can have on long term operating expenses as well as the value of prop- erly configuring the system to match the process and application requirements will yield significant savings over the life of the system.

14 August2014 TechnicalExclusive caption C Choosing Cartridge Dust Collector Filters for Processing Applications Cartridge dust collection systems are the preferred technology for most dry processing applications today, and there are many different pleated filter cartridges available for these collectors. As you face stricter air quality and combustible dust regulations, coupled with tighter internal cost controls, choos- ing and using the best dust collector filter for your process is more important than ever. Making an in- formed choice can improve your collector’s dust cap- ture efficiency and reliability while reducing energy and maintenance requirements. Types of Filter Media There are two basic categories of media commonly used in pleated cartridge filters. The choice is usu- ally driven by dust type, operating temperatures, and the level of moisture in the process. 1. Nonwoven cellulosic blend: This media is the most economical choice for dry dust collection ap- plications at operating temperatures up to 160°F. Sometimes the fibers will incorporate a coating that en- hances moisture resistance. However, cellulose media as a category are not as resistant to moisture as synthetic poly- ester. 2. Synthetic polyester me- dia or polyester-silicon blend: This lightweight, washable media can handle dry appli- cations with maximum oper- ating temperatures ranging from 180°F to 265°F. These filters are washable and can recover from a moisture ex- cursion but are not intended for wet applications. Either type of media can be treated with a layer of nano fibers that boosts the efficiency and yields other benefits as well. Nano filter technology has advanced in recent years, and the newest generation of nano fibers can perform well even in the most extreme conditions. When a layer of nano fibers is applied on top of the base media - whether cellulosic or polyester - the nano coating promotes surface loading of fine dust, preventing the dust from penetrating deeply into the filter’s base media. This translates into better dust re- lease during cleaning cycles and lower pressure drop readings through the life of the filter, which, in turn, promote longer filter life as well as energy savings. Standard and nano filter media can also be treated with compounds that deliver special performance properties. Flame-retardant media are treated with a chemical that provides fire retardant properties for use where there is a risk of fire or explosion. Companies involved in metalworking processes such as plasma and laser-cutting, grinding, or welding commonly use filters with flame-retardant media. Conductive or anti-static filters may be used where conveyed dusts generate static charges that require dissipation. Typically, static dissipation is achieved by impregnating a cellulose filter with a carbon coat- ing or a synthetic filter with an aluminized coating. Applications for these filters include fumed silica dust, plastic, PVC, or composite dusts, and carbon black/toner dusts. Cartridge filters with anti-static media can also be used in explosive dust applica- tions, making it possible to conform to NFPA re- quirements and lessen the risk of ignition sources due to static electricity charges. In combustible dust applications where the minimum ignition energy of the dust is below 3 millijoules (mJ), the NFPA requires the filters to be conductive, bonded, and grounded to the filter housing. Selection Tips Following are five tips that can further help you de- termine the best filter for your application: 1. Understand the different measures of filter effi- ciency and how to apply them. There are two meth- ods that dust collector filter manufacturers typically use to express filter efficiency. Gravimetric analysis is based on particle capture by weight: For example, filter efficiency might be stated as 99.995 percent on particles of 0.5 µm or larger by weight. Filter efficiency may also be expressed as a Minimum Efficiency Reporting Value, or MERV, based on a scale from 1 to 16, with MERV 16 being the highest efficiency. By Rick Kreczmer, Camfil APC Conductive (anti-static) filters may be used where conveyed dusts generate static charges requiring dissipation. ES466424_PB1408_014.pgs 07.16.2014 23:34 UBMblackyellowmagentacyan
www.PowderBulkSolids.com 15 August2014 The MERV scale was developed for the HVAC filter market and does not take into account the way a dust collector operates (i.e., it pulse-cleans filters periodically when a dust cake builds up). Though MERV and gravimetric efficiency ratings are useful tools for comparing filters, you should not rely on these measures alone to determine efficiency. It is more relevant to make sure you are satisfying OSHA or EPA re- quirements for filter performance – OSHA if you are discharging the air and recirculating it indoors downstream of the collector, the EPA if you are discharging the air outside or into the environment. Mass density efficiency, defined as the weight per unit volume of air, is the best predictor of a filter’s OSHA compliance. For example, OSHA might require that emissions will not exceed 5 mg/cu m at the discharge of the dust collector. Similarly, the EPA doesn’t care about percentage efficiency claims; they want to know that emissions will be at or below required thresholds, typi- cally stated as grains per cu ft or mg/cu m. Concerned about which effi- ciency measure(s) to use? If so, you are not alone. But there is a way to cut through the confusion and make sure your bases are covered: Require your filter sup- plier to provide a written guaran- tee of performance stating that the filters you select will satisfy applicable OSHA or EPA require- ments. It is worth noting here that ASHRAE is developing a new standard specifically for measur- ing performance of dust collector filters. Finalization of that stan- dard, however, is at least a couple of years away. 2. Test your dust. The collec- tion and testing of dust samples is a long-established practice used by processing professionals to make informed dust collection decisions. While dust testing has always been good practice, it is rapidly becoming a necessity in today’s regulatory climate. There are two types of dust testing: (1) bench testing, which pinpoints physical properties of the dust, and (2) explosibility test- ing, which determines whether a dust is combustible. Bench testing involves a series of tests that provide valuable data for filter selection. Particle size analysis reveals the dust’s par- ticle size distribution down to the submicron range to determine the filtration efficiency needed to meet emissions standards. This test pinpoints both the count (the number of particles of a given size) and the volume or mass spread of the dust. Knowing both is important because many dusts are mixed. A video microscope provides visual analysis of the dust shape and characteristics. Together with particle size analysis, this tool is vital for proper filter selection. For example, a microscope may be needed to detect oil in the dust. Moisture analysis equipment measures a dust’s moisture per- centage by weight, providing information that can prevent moisture problems. A humid- ity chamber is used to see how quickly a dust will absorb mois- ture. This helps to identify hy- groscopic (moisture-absorbent) dust which requires widely pleated filter cartridges, as these sticky dusts cause filters to plug. Additional bench tests can help to determine the optimal design of other dust collection system components. It is not necessary to bench-test dust 100 percent of the time, but if there is anything at all unusual about the process and/or the dust, it’s a good idea. To determine whether a dust is combustible, it should undergo separate explosibility testing as stated in NFPA Standard 68. If a dust sample is not available, it is permissible to use an equiva- lent dust (i.e., same particle size, etc.) in an equivalent application to determine combustibility. But once the dust becomes available, it is still recommended that you go back and test the dust using either the 20-l test method de- scribed in ASTM E1226-12a or the similar method described in ISO 6184/1. Using your dust sample, the lab will start with a screening test to determine whether the Bench testing identifies physical proper- ties of the dust, aiding filter selection. An engineered test is performed at an official testing facility to confirm that this dust collector can withstand an explo- sive event. Scan QR code to view brief explosion test video. ADVERTISEMENT Wear resistant pipe bends Jason Hunter, Pelletron Corporation Pneumatic conveying of abrasive materials wears out standard, long- radius pipe bends quickly. There are various types of pipe bends designed for extended lifetime available. Pelletron developed a special elbow that withstands the most abrasive materials. Wear problems are common in dilute phase conveying systems with high velocities. The conveyed product slides along the elbow wall at a high velocity and high centrifugal forces press the conveyed material against the outer metal surface. The resulting friction causes the elbow walls to wear out quickly. Pelletron developed a unique, patented conveying pipe elbow that is trade named the Pellbow®. It is especially designed to minimize damage caused when solid particles are injected into a high velocity con- veying system — the higher the velocity, the higher the friction. Using a Pellbow® avoids the problems caused by friction in traditional elbows. P PneumaPneuma radius prad us p designedesign specialspe By design, material flowing through the Pellbow® forms a pocket or “impact zone” and moves slowly upward and out. Incoming material is deflected at 90 degrees with minimum resistance and no impact damage. The Pellbow® is wear-resistant making it the ideal solution for conveying abrasive products. The Pellbow® is self-cleaning when the material flow is stopped and it works in all installation positions. Long-radius elbows or other types of pipe bends in existing vacuum and pressure dilute phase conveying systems can be easily retrofitted with the Pellbow®. The pressure drop compared to long-radius elbows is minimally higher. The minimum product-to-air ratio of 3:1 or higher guarantees best results. The Pellbow® is designed to fit all kinds of pipe and tube connections. The Pellbow® is available in aluminum, stainless steel and cast iron for pipe sizes from 1.5” up to 12”, as well as in surface hardened versions.

Powder Bulk Solids16 TechnicalExclusive August2014 dust is combustible. If the dust is not combustible, testing will stop there. If it is combustible, the lab will conduct further testing on dust cloud parameters to pinpoint the Kst (defined as the deflagra- tion index of a dust cloud, or rate of pressure rise) and Pmax (the maximum pressure in a contained explosion). Explosibility testing is per- formed primarily to help deter- mine what explosion protection or prevention equipment is needed on your dust collector and related components. But it can also play a role in filter selection. For example, testing for the mini- mum ignition energy can help determine if conductive filters are needed. 3. Evaluate total cost of own- ership. When choosing between two cartridge filters with the same rated efficiency, some pro- cessors will regard these items as a commodity and simply choose the lowest-priced filter. But as with most purchasing de- cisions, initial cost is only one factor, and it requires a “Total Cost of Ownership” (TCO) evalu- ation to make the best filter se- lection. TCO helps you determine what it really costs to own your dust collector filters by calculating all the components of true filter cost: energy, consumables, and main- tenance and disposal. A reputable filter supplier should have soft- ware to help you perform the calculations. The TCO evaluation will ultimately save you money, time, and energy by ensuring the most cost-effective filter choice. (Note: A detailed article on TCO appeared in the August, 2010 is- sue of Powder Bulk Solids and can be accessed at www.powder- bulksolids.com.) 4. Consider a nano fiber me- dia even if you do not have a “difficult” dust challenge. When they were first introduced to the market, nano fiber media were regarded as a high-end choice lim- ited to exotic or demanding dust- capture challenges. Though these filters carry a cost premium, their use is becoming more widespread for all types of applications as processors come to understand their benefits. Compared to stan- dard media, nano fiber filters of- fer higher filtration efficiencies as well as better energy perfor- mance, superior cleanability, and greater resistance to wear and tear from pulse-cleaning. Because of these benefits, some filter ex- perts believe nano fiber media will become standard in the fu- ture. As a rule of thumb, if you are looking for high initial filtration efficiency and better release of dust through surface loading, then nano fiber media should be the default choice. Beyond this, even for a “non-high-perfor- mance” application, a TCO analy- sis (above) might be worthwhile to find out if the added cost of nano fiber media will be more than offset by resulting savings in energy and filter change-out and disposal costs. In a system operating at very high airflow, for example, a half-inch reduc- tion in pressure drop achieved with a nano fiber filter can make a huge difference in energy con- sumption. 5. Look for a uniform wide pleat media design. Many filter manufacturers add filter media to the point where the pleats are so tightly packed that when dust gets between the pleats, the re- verse pulse cleaning system of the dust collector will not eject the dust from the pleats. This in- creases the resistance of the air through the filters and diminishes airflow. The key is to use a wide pleat where 100 percent of the media is usable. A wide pleat filter allows the collected dust to release from the filter, keeping the resistance lower through the filter for a lon- ger time. Some wide pleat filters use state-of-the-art technology of synthetic bead pleat separators to ensure pleats are kept wide and open for the best dust release possible. These separators pre- vent the media from folding over on itself, which could cause the filter to plug. A wide pleat filter will often contain less total media area than a tightly pleated model. But the total square footage of the media is not what you want to look for: It’s the total usable media area that’s really impor- tant. Rick Kreczmer has held numer- ous positions with Camfil APC in the U.S. and Europe, and cur- rently serves as aftermarket sales manager.

Dust Collection Air Pollution Control ProductFocus Spark Detection and Suppression The pneumatic conveying of com- bustible dusts carries inherent risks for dust fires and explosions in many applications. Grinding, cutting, and drying operations can often cause sparks that are typi- cally the ignition source for fires and explosions in duct collectors and air filtration equipment. The FLAMEX system is specifically de- signed to address these hazards by detecting and suppressing sparks in the pneumatic ductwork before they can reach dust collectors or storage bins. Infrared detectors sense sparks being transported through ductwork to a dust collec- tor.

This technology consists of the three process compo- nents: Strandphase conveying, Pellbow pipe bends, and the DeDuster for fines removal. Unlike dense phase systems, the pellcon3 process does not create dynamic forces throughout the line, reducing costs for building construc- tion and silos. Maximum conveying pressure is below 22 psi, making use of medium pressure rotary valves and blowers possible, and the flexibility of turndown ratios in a Strandphase system allows operation without an additional air management system. With pellcon3, conveying line sizes are smaller than in dilute phase or dense phase systems, and the efficient use of energy provides additional savings in the ongoing cost of operation.

Powder Bulk Solids20 Editor’sSpotlight August2014 • Pneumatic Conveying Pneumatic Air-Vey Magnets Air-Vey magnets are designed to remove ferrous contaminants from products in dilute-phase pneumatic conveying systems that operate at 15 psi or less. These units are used to ensure product purity and protect process equip- ment. The flow-through area of the housing is engineered to maintain the same product velocity without an appre- ciable drop in pressure. These magnets install easily in horizontal, vertical, or angled positions with compression-type couplings or via welding in place. Puritan Magnetics Inc., Oxford, MI 248-628-3808 www.puritanmagnetics.com Pneumatic Weigh Filling System This pneumatic gain-in-weight filling system conveys and weighs free-flowing bulk solids, and discharges the material into bulk bags dust-free. The filter receiver of a Pneumati- Con vacuum dilute-phase pneumatic conveying system is mounted on load cells, enabling the controller to stop the flow of material once an accurate batch weight has been accumulated. A “fill” button on the Twin-Centerpost bulk bag filler actuates a blower to remove bag creases, and then opens a slide gate valve to discharge the batch into the bag at high rates, as a vibratory deck densifies the material to stabilize the bag. The filler is mounted on a secondary set of load cells to check-weigh the filled bag. A port within the discharge spout vents displaced air and dust to a remote bag house. The controller then releases the bag straps and deflates the spout seal, allowing the operator to tie-off the spout and remove the filled bag. Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com Rotary Valves Coperion K-Tron offers Heavy Duty (HD), Maximum Duty (MD) and Quick-Clean (QC) Aerolock rotary valves, as well as Light Duty (LD) and Blow-Through (BT) models.

Coperion K-Tron Salina Inc., Salina, KS 785-825-3884 www.coperionktron.com Pocket Elbows The Dense Flow Pocket Elbow is designed for use on pneumatic conveying pipelines, and is most effective when highly abrasive materials are being transported. During a pneumatic convey cycle, the elbow traps incoming material at the elbow’s deflection point. The material that is trapped in the “pocket” then acts as a barrier for any remaining material being conveyed, and greatly increases the lifespan of the elbow. The Pocket Elbow can directly replace any existing pneumatic elbow when combined with Dense Flow Pipe Stubs. The advantages of the Dense Flow Pocket Elbow are increased elbow lifespan, less downtime, lower maintenance costs. JDB Dense Flow Inc., Palm Harbor, FL 800-822-3569 www.jdbdenseflow.com Flex Tube Diverters Eliminate Cross-Contamination Vortex Flex Tube Diverters eliminate material cross-contamination commonly found in the food, plastic, and chemical industries. They are ideal to divert, or converge, a wide range of dry mate- rials, including sugar-based solids, in gravity or dilute phase pneumatic conveying systems. Flex Tube Diverters feature two or three ports that utilize a basic sliding orifice blade design. A tube stub is welded to an orifice-style blade, and a flexible hose is then attached to the tube stub. As the diverter blade is shifted, a flexible hose moves from one port to the other, allowing the con- venience of continuous conveying. When one port is open, the other ports are sealed and elimi- nates any internal ledges or pockets where material can become lodged and remain trapped.

www.PowderBulkSolids.com Editor’sSpotlight 21 August2014 • Pneumatic Conveying Dense Phase Pneumatic Conveying Systems Dynamic Air pneumatic conveying systems handle a wide range of materials and bulk densities at rates from 500 lb/hr to 450 tn/hr, over distances to 6000 ft. Each system is custom-designed from one of 16 different conveying concepts to provide a conveying solution that fits the process perfectly. One conveying concept, the Full-Line Concept system, has many advantages over more traditional dense-phase concepts with regard to degradation and energy consumption. In addition, it is clean and totally enclosed and can be fully automated to convey to packaging or process bins. Few moving parts are utilized, as the prime mover is standard plant compressed air at 100 PSIG. Cross contamination is never an issue as the convey- ing line can be purged clean when switching between materials. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com Blow-Through Feeder/Airlock Fine powders can easily over-aerate, which reduces material feed efficiency in high-pressure pneumatic conveying applications. ACS Valves designed the BT Series blow-through feeder/ airlock to ensure optimal throughput of hard-to-convey materials. The BT Series 12-vane rotary valve design decreases excess aeration of the material during conveying with an integrated vent port on the return side of the valve housing that vents pocket air leakage. The BT design element minimizes the flow path of air through the rotor clearances, improving ma- terial pocket release. With minimal air leakage, the resulting low, effective pressure drop of the BT Series optimizes ma- terial flow density, improves material conveying efficiency, and reduces total compressed air consumption.

24 August2014 TechnicalExclusive Figure 1 - Dust Explosion Pentagon I Secure Cloud-Based Industrial Monitoring Solution It is well known that transporting certain dry dusty materials can create explosive atmospheres. Five conditions, known as the “Dust Explosion Pentagon”, have to exist in order for the explosive state to oc- cur. First, there needs to be a high concentration of dust (fuel), followed by an ignition source (heat) and oxygen (oxidizer). If all of these appear in a confined space with dispersion, an explosion can occur. The most common ignition sources have long been iden- tified as over-heated bearings, misaligned belts, and belts that are slipping. The industry is saturated with various sensors and controllers that monitor these conditions to prevent explosions. Regardless how well these systems work there is one problem with all of them: human error. With the ever-growing demands on site performance and efficiency at ter- minals and processing facilities, decisions to bypass safety equipment has become an ever increasing is- sue. With mount- ing pressures, site personnel may risk keeping a machine in opera- tion even after an alarm has been detected, putting the plant and all personnel at risk. Without backend reporting systems and data logging, this dangerous practice can go on undetected by up- per management. In order to combat this issue, 4B Components has developed a solution that in- troduces a greater level of transparency and record keeping. HazardMon.com is a secure cloud-based industrial monitoring solution that allows any regis- tered user to log in and see all their facilities in real- time from anywhere in the world. This product of- fers seamless integration with 4B’s T500 Elite Hotbus hazard monitoring system. HazardMon.com Features Features of the HazardMon.com include the follow- ing: • Secure login and data transfer with standard 256- bit (SSL) encryption, or an optional virtual private network (VPN) connection can also be created • No server or PLC is required, so there is no ad- ditional hardware to replace or backup, which also eliminates upkeep and upgrade costs. • Data is sent directly to 4B’s cloud server, and automatically backed up in multiple off-site locations making the data extremely safe and secure. This al- lows data to be easily recovered and analyzed in the case of an on-site event, such as an explosion. • Live system dashboard, historical data, and cus- tomizable graphs can be viewed on any Web-enabled device (smartphone, tablet PC, desktop or laptop computer). • Email alert notifications can be sent to notify specific users whenever a change in the system’s health is detected. • New features are constantly being developed to improve the end user experience, and with HazardMon.com’s cloud-based technology, your facil- ity will always be at the leading edge of technology. Live System Dashboard With HazardMon.com it is possible to view multiple sites from one system dashboard page (see figure 3).

All sensor data can be viewed in real-time using any standard Web browser such as Mozilla Firefox, Google Chrome, or Internet Explorer (see figure 4). The Web site is completely dy- namic and the sensor status and value are updated automatically without the need to refresh the webpage. The Web site was de- signed to dynamically resize as the screen resolution changes and it is optimized for tablet and mo- bile phone platforms. Historical Data Analysis All data can be viewed as graphs. A unique drag-and-drop feature allows you to pick specific sen- sors of interest and compare them side-by-side in one graphical view (see figure 5). Time windows can be selected, ranging from 1 hour to 30 days. The graphs are inter- active, allowing you to use your cursor to mouse over any event to show specific values and sen- sor statuses. All alarms are stored in a sepa- rate alarm log (see figures 6 and 7). Using the Web site filtering options, it is easy to generate a report and download it into a standard spreadsheet program. All the alarms are grouped into different alarm types, like “Alarm Detected”, “Alarm Cleared”, “Device Power Up”, etc. This al- lows information to be extracted in a few clicks and create a report in seconds. Email and Text (SMS) Notifications Engine A flexible notification system al- lows any user to receive email or text message notifications. Notification can be sent when sensors go in and out of alarm; when the Internet connection between the T500 Hotbus system and the server is lost or when an alarm has not been cleared for a number of minutes. It is also possible to receive notifications only when an alarm has not been cleared for a specified number of minutes. Report Generation Tool An advanced analytics tool allows reports to be generated that sum- marize the safety and efficiency of the factory. Currently it is pos- sible to see which sensors caused the majority of alarms, which hours of the day had most alarms, and the types of alarms.

Powder Bulk Solids26 TechnicalExclusive August2014 dates of reports can easily be al- tered and the report re-generated. Reports can be saved to the user’s PC in a single click. Automated Maintenance and Testing Functionality It is important to periodically check that your monitoring sys- tem will detect an alarm when a dangerous condition occurs. The current standard in the industry is for technicians to walk around the site and manually test each sensor. A paper report is then generated and in some cases, converted into a digital format (Microsoft Excel for example). There is still absolutely no guar- antee that the technician actually performed any of the testing. HazardMon’s sensor testing func- tion ensures that test procedures are carried out, logged, and re- ported within the system. This feature provides managers docu- mented evidence that each sen- sor has been tested to ensure it is working correctly. (See Figure 10). To initiate a system test, a user would go to the “Maintenance” tab within HazardMon.com and choose a sensor to test. During testing, HazardMon temporarily stops alarm notifications for this sensor, so that no nuisance alarm notifications are sent out. The user has five minutes to trigger an alarm and confirm the sensor is in proper working condition or needs to be replaced. The whole process is logged automatically, and a maintenance report can be generated after testing has been completed. Conclusion As more facilities install moni- toring systems to ensure the site’s safety, the main safety concerns, human error, and the lack of transparency still exist. HazardMon.com combined with 4B’s hazard monitoring systems gives management real-time ac- cess to all critical monitoring data. This increases transparency, cuts down on human error, and helps to verify that company safety poli- cies are being adhered to.

Freeman Technology, Tewkesbury, UK +44 (0) 1684 851 551 www.freemantech.co.uk Compact Vibrating Rod for Small Bins BinMaster introduces the new CVR-625 mini vibrating rod, a compact point level control designed for use in small bins and hoppers where other level sensors will not fit. The new ver- sion features an updated design that allows for the detection of light materials with a bulk density as low as two. The rod can be used for measuring plastics, food, seed, chemicals, and other pellets or dry granular solid materials. The signal from the elec- tronic circuit of the CVR-624 excites the single rod of the instru- ment to vibrate on its resonance frequency of approximately 460 Hz. When material covers the rod of the probe, the vibra- tion stops. This is sensed by the electronic circuitry that forces its output relay to switch. When the blade becomes uncovered, the vibration will restart and the relay will switch back. Due to its vibrating technology, the mini vibrating rod is able to over- come the difficulties associated with changes in dielectric con- stant, humidity, temperature, and material density, and elimi- nates the problem of false signaling due to material wedging and buildup associated with Ôtuning forkÕ type probes.

30 August2014 TechnicalExclusive caption O High-Tech Plastics Are Economical and Environmentally Friendly One of the greatest advantages of plastic is that it can replace heavier metal – resulting in more light- weight automobiles. DuBay Polymer GmbH is one of the world’s largest plants for the production of high- tech plastic. During the refinement process of com- pounding, a variety of dusts and fumes are created that must be reliably extracted. DuBay Polymer in Hamm-Uentrop annually pro- duces up to 80,000 tons of polybutylene terephthal- ate (PBT). The polymer is the primary component of premium plastics that are utilized in numerous in- dustries because of their flexibility. DuBay was estab- lished in 2001 as a joint venture between LANXESS and DuPont and has been experiencing steady growth in recent years. Lighter Plastics Trend A driving force behind this development is the current trend toward replacing met- als with durable and versatile high-performance plastics, or utilizing both materials as a composite (hybrid technol- ogy). “One advantage of plastics compared to metal is the fact that the components are lightweight, resulting in lower fuel consumption, lower costs for the auto- mobile owner and reduced CO2 emissions. A significant advantage for the budget and for the environment,” stresses Michael Pasch, the materials processing engineer responsible for the com- pounding system. By adding a bulking agent, fibers, and other additives, the PBT polymer achieves certain targeted character- istics in such a treatment process. DuBay employees can produce plastics sturdy enough for use as compo- nents capable of withstand- ing heavy use loads such as hinges, housings, heavy foot traffic, or ease of access de- vices. “Because of their heat resistance, automotive suppliers also utilize these plastics in components which are subjected to high temperatures, such as headlight mounts,” adds Pasch. Dual-Stage Separation Technology In the beginning of 2012, DuBay introduced a second compounding system and thereby doubled its capac- ity for high-end plastics. During the planning stages, the system operators requested improvements to the existing labor-intensive extraction process. The key recommendation was provided by Lanxess, the parent company, which has experienced long-lasting results with Keller separators, especially for plastic refinement processes. The requirements of Pasch and his colleagues are consistent with the two-part filtration technology used by Keller for compounding processes. “First we separate dry dusts created during the weighing, mixing, and addition of additives by utilizing a dry separator. Then, any adhesive aerosols released dur- ing extrusion processes are separated by a wet sepa- rator,” explains Nick Herfurth, vice president of sales and operations at Keller. Decreased Sludge Facilitates Disposal There is a frequent risk of deposit buildup and fires inside the ductwork. To offset this risk, Keller employs spray nozzles that rinse the dirty air duct with water over the entire surface. “The evaporative cooling creates a sudden temperature change which results in the condensation of high boiling point solvents,” says Herfurth. The subsequent wet separa- tion removes liquid in addition to solid particulate from the exhaust flow and separates them from the waste water in the sedimentation basin. The result- ing sludge is discharged automatically and continu- ously by a sludge remover and sinks into an adjacent disposal container. “We are pleased that we no lon- ger remove the sludge manually – the operation is now much simpler and a cleaning is seldom neces- sary,” Pasch adds. “The fact that dust generated at the mixing platforms is extracted by a separate dry separa- tor further reduces the amount of sludge that ac- cumulates in the wet separator,” says Pasch. “This facilitates disposal and is more economical. In ad- dition, the dry separator is very easy to maintain. The filter element cleaning is controlled automati- cally by differential pressure or at pre-set time intervals. Full disposal containers can be emptied during operation. The level monitor indicates –Keller dry separator Vario ES465349_PB1408_030.pgs 07.15.2014 03:34 UBMblackyellowmagentacyan
www.PowderBulkSolids.com 31 August2014 normally after an interval of some weeks – that the container can be emptied. Dry Separation Process Must Meet ATEX Guidelines The requirements of the ATEX guidelines apply to the operation of a compounding system (explo- sion protection guidelines of the European Union). The Vario dry separator is equipped with a high- quality pressure relief valve that can flamelessly absorb any energy created in the unlikely event of an explosion. One of Keller’s pat- ented back pressure flaps can pre- vent the spread of the shock wave and flames into the workplace. Reliable Filtration Provides System Reliability Pasch and his colleagues manage the compounding system from their control station. A number of monitors and displays assist them. “We only leave if a mal- function message is displayed and this rarely occurs,” says Pasch. The high reliability not only fa- cilitates the operator’s work, but also boosts the rate of produc- tion. “The separation operates smoothly nearly without supervi- sion,” says Pasch. When asked if Keller would be considered for the potential purchase of a third compound- ing system Pasch said, “Keller is one step ahead as far as filtra- tion technology is concerned. Of course they would be in conten- tion.” For more information on Keller USA Inc. (Fort Mill, SC), call 803-396-2000 or visit www.kellerusa.com. High-tech plastics are usually delivered as granulate.

Powder Bulk Solids32 Editor’sSpotlight August2014 • Storage Disk-Type Fluidizers Solimar offers disk-type fluidizers for the discharge of powders and bulk solids. This complete line offers long- wearing aeration devices for many applications including silos, hoppers, bins, and trailers. The fluidizers are particularly effective at preventing rat-holing and bridging by utilizing air pressure to move the material while gently vibrating the vessel wall. The company’s products are divided into two distinct application areas. Silo products include a line of disk aerators that enhance the flow of powders in various storage devices, and transportation products including disk aerators designed for dry bulk trailer usage. Features include: superior sealing properties; optimized air volume to better unload silos or trailers; an original durable design, in two diameters (2 and 4 in.), that will not crack, wear prematurely, or clog like fabric pads; FDA-approved ma- terials with operating temperatures up to 450ºF; and a metallic detectable version for food applications. Solimar Pneumatics, Minneapolis, MN 800-233-7109 www.solimarpneumatics.com Side Door Bin Used primarily in the food and chemical industries for discharging large volumes of dry products, the side door bin features a large door opening that allows product prone to bridging to discharge quickly and completely. This new gasket-free door design makes this container an even more economical choice for handling dry materials with op- tions of stainless, carbon steel, or aluminum construction, and capaci- ties up to 100 cu ft. The stackable bins are combined with a discharge station to automatically tilt bins to 45 degrees. Custom Powder Systems, Springfield, MO 417-868-8002 www.custom-powder.com Rolled, Tapered-Panel Tanks The best features of bolted and field- welded tank construction have been combined in the rolled, tapered panel (RTP) design. Field construction is ac- complished utilizing a synchronized, hydraulic screw jack process that keeps field crews on the ground. This process receives the highest industry ratings for quality control and safety in the field. Tank Connection designs, manufac- tures, and installs all four types of steel storage tanks, including bolted RTP, field-weld, shop-weld, and hybrid tank designs. Tank Connection, Parsons, KS 620-423-3010 www.tankconnection.com Silo Sweep Auger The new Silo Sweep Auger from Guttridge Ltd is a robust machine for the automated emptying of grain silos. Grain silos empty under gravity but as grain lev- els drop this process stalls. One option is to dig out the residual volume manually, but this incurs substantial labor costs and raises HSE issues. The alternative is to use a sweep auger, which as the name suggests, sweeps across the silo floor, transferring the remaining grain via a screw to the silo outlet. The Silo Sweep Auger is made from galvanized steel to improve longevity and reduce the risk of product contamination from flaking paint. Rubber blades ensure an efficient sweep of the silo floor while an enclosed clutch and motor mechanism prevents grain ingress and subsequent damage, improving reliability. The patented drive design delivers the very highest levels of efficiency by reducing slip and strain within the system.

www.PowderBulkSolids.com 33 August2014 TechnologyReview Dust Collection Air Pollution Control ProductFocus SpaceSaver High-Efficiency Dust Collector The SpaceSaver dust collector is up to 75% smaller than tra- ditional dust collectors, offering long-lasting, leak-free cartridges. With a footprint as small as 27 x 38 in., the SpaceSaver is suited for applications with limited space re- quirements in terms of both cross- section and overall height, as well as in areas of the plant that aren’t connected to central dust collec- tion systems. Many cartridge styles are available to best fit the appli- cation, with sizes ranging from 2 to 48 cartridges per collector. The SpaceSaver uses directed air flow fire to pulse the cartridges. Schenck Process, Whitewater, WI 262-473-2441 www.schenckprocessinc.com Modu-Kleen Downdraft Series Dust Collector The Modu-Kleen downdraft dust collector contains fugitive dust. The air enters at the top of the dust collector housing and flows downward to the cartridge filters, improving the filtering process and the material-to-air ratio. Air veloci- ties are lower than those with a conventional dust collector, reduc- ing the load on each filter car- tridge and extending filter life. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com High-Temperature Wax Technology for Induction Seal Liners Tri-Seal has introduced a high-temperature wax technology designed to bolster the stability of two-piece induction seals that are stored or distrib- uted in challenging high-temperature conditions. The solution is specifi- cally engineered to reduce costly (and potentially dangerous) seal-related product leakage from packaging closures. This is a particular cause of concern for lined closures and seals shipped or stored in high-temperature conditions, such as those found in India, Israel, Southeast Asia, Australia, Puerto Rico, and Latin and South America, as well as southern American states and, more seasonally, throughout greater North America. When exposed to high temperatures even for brief periods, the wax component of a two-piece induction seal can be prematurely absorbed into the pulp layer prior to closure application, thereby potentially compromising seal integrity during the filling and capping process. Often, the result is a “potato-chip effect” whereby the heat seal portion of the circular seal’s outer edge curls and separates from the backing material. During capping, the heat seal portion can fold under and not fully seal on the bottle finish. The ensuing leakage is a particular problem for companies who manufacture and distribute highly sensitive or unstable products, such as those found in pharmaceutical, agricultural, chemical, and au- tomotive industries.

Powder Bulk Solids34 Editor’sSpotlight August2014 • Particle Analysis Morphologi G3-ID Characterizes Discrete Particle Populations within Powder Blends The Morphologi G3-ID from Malvern Instruments is a powerful particle characterization system that combines automated imaging with Raman spectroscopy. Using these technologies, it delivers component specific particle size and shape distribution data for discrete populations within a powder blend. One application is in the analy- sis of environmentally friendly cements, where a proportion of clinker is replaced with ‘waste’ materials, such as blast furnace slag or fly ash. For most cements, laser diffraction particle sizing meets routine analysis re- quirements. However, for cements containing replacement materials it is often necessary to measure the particle size of individual compo- nents within the blended product. Morphologi G3-ID provides statistically relevant particle size and shape data for each component, even where these are morphologically similar. These data are helping manufacturers optimize the performance of newer cements and manage development and future production costs. Malvern Instruments Inc., 508-768-6400 Westborough, MA www.malvern.com Particle Insight Size and Shape Analyzer Particulate Systems’ Particle Insight is ideal for ap- plications where the shape of raw materials – not just the diameter – is critical to the performance of the final product. The instrument offers up to 28 different shape parameters analyzed in real-time in either aqueous or organic solvent suspensions. The Particle Insight operates in a range suitable for a wide variety of industrial, biological, and geological specimens from 1 to 800 micrometers. Its unique recirculating sample module and precision optics are designed to acquire and report statistically valid measurements quickly, an essential quality con- trol capability in many manufacturing processes. Particle Insight features include the ability to track sample shape changes over time as well as the capability to store a collection of particle images. The user has the option of viewing only those particle images that meet any combination of the analyzer’s 28 shape parameters. It also has an automated fill-and-rinse feature allowing for true unattended operation.

    Inlet/Outlet Chemical Isolation OR OR Inlet Protection Designedto react within milliseconds of detecting an explosion, a chemical isolation system can be installed in either inlet and/or outlet ducting. The chemical isolation system creates a chemical barrier that suppresses the explosion within the ducting, reduces the propagation of flame through the ducting and minimizes pressure increases within connected process equipment. Vertical Plenum A plenum that is bolted to the dirty air section of the collector. The explosion vent is mounted to the top of the plenum which effectively transitions the pressure and flame fronts from a horizontal to a vertical configuration. A vertical configuration make it possible to explosion vent through a roof and/or direct the pressure and flame fronts to a safe location as outlined in NFPA standards. In most cases, ducting and weather hoods are required to be compliant with NFPA standards to protect the explosion vents from the elements and other debris. Access panels are provided on the ducting so that easy inspection and/or replacement of the explosion vent is made possible without removing the ducting and weather hood. CHEMICAL ISOLATION EXPLOSION VENT DETECT & SUPPRESS AND MORE Explosion Venting Sequence 1 2 3 4 Fast-Acting Valve Designed to close within milliseconds of detecting an explosion, the fast-acting valve installs in either inlet and/or outlet ducting. The fast-acting valve creates a mechanical barrier within the ducting, which effectively isolates pressure and flame fronts (from either direction) from being able to propagate further through the process. Blast Plate A Blast Plate is a deflector mounted directly in front the explosion relief area. The deflector is designed to restrict the flame length ejected from the collector in the event of an explosion. For vessels that are not greater than 706 cubic feet, the deflector is designed to reduce the axial (front- centerline) safe distance by 50 percent.

    Flameless Vent Designed toinstall over a standard explosion vent, the “FlamQuench SQ” extinguishes the flame front exiting the vented area not allowing it to exit the device. This allows conventional venting to be accomplished indoors where it could otherwise endanger personnel and/or ignite secondary explosions. Chemical Suppression Designed to react within milliseconds of detecting an explosion, a chemical suppression system is installed in the collectors dirty air section. The chemical suppression system prevents expanding a deflagration by releasing a chemical agent. This system is often used in order to put combustible dust collectors inside the factory where you can’t vent to the outside. Explosion Vent Designed to be the “weak” link of the vessel, explosion vents open when predetermined pressures are reached inside the dust collector allowing the overpressure and flame fronts to exit to a safe area. Explosion vents minimize damage to the dust collector caused by overpressure created by a deflagration. Camfil APC’s standard explosion vents are ATEX certified and NFPA compliant. The purpose of the Stinger is to prevent a deflagration (explosion) that could occur in the dust collector from traveling back down the inlet pipe back into the workspace/process. The iSMF has been proven to isolate the downstream equipment from the progres- sion of a flame front during an explosion. The Farr Gold Series® dust collector with an integrated Safety Monitoring Filter allows you to recirculate exhaust air back into the work space when your dust is explosive. The key advantage of this device is that it prevents the transmission of explosive dust (fuel) from the collector. Integrated Safety Monitoring Filter Detect and Suppress These systems protect the dust collector from ignition sources such as sparks or embers. It detects them and activates a suppression system that extinguishes them before they reach the collector.

    Powder & BulkSolids6 Editor’sChoice August2014 Mercury Intrusion Porosimeters Provide Advanced Performance and Safety In addition to offering speed, accu- racy, and a wide measurement range, mercury porosimetry also permits the calculation of numerous sample prop- erties such as pore size distributions, total pore volume, total pore surface area, median pore diameter, and sample densities (bulk and skeletal). Micromeritics’ AutoPore V Series mercury porosimeters can determine a broader pore size distribution more quickly and accurately than other methods. These instruments also include enhanced safety features and offer new data reduction and reporting choices that provide more information about pore geometry and fluid transport characteristics. The AutoPore V is available in two models to best match the require- ments of quality assurance and research labs. The AutoPore V 9620 has a pore size range of 500 to 0.003 micrometers with two high-pres- sure (60,000 psia maximum pressure) and four low-pressure analysis ports. The AutoPore V 9605 contains two high-pressure (33,000 psia maximum pressure) plus four low-pressure analysis ports measuring pore sizes from 500 down to 0.005 micrometers. Micromeritics Instrument Corp., Norcross, GA 770-709-7108 www.micromeritics.com Patented Bulk Bag Material Conditioner Discharging bulk bags containing material that has solidified, hardened, or agglomerated can cause serious operational bottlenecks. Conditioning and emptying bulk bags can be dangerous if the proper equipment is not utilized. This patented system utilizes hydraulically actuated, heavy wall tubular steel pivoting conditioning arms. Each conditioning arm features “v-shaped” tubular steel breaker profiles that safely and efficiently return solidified materials to a free-flowing state. The unit features a proprietary automated control package that eliminates operator variability and increases productivity. A powered rotary lift table allows complete material conditioning of the bulk bag on all sides, and top to bottom. The unit features an ultra-compact footprint and machine guarding for operator safety. Material Transfer & Storage Inc., Allegan, MI 800-836-7068 www.materialtransfer.com Silo Weight Monitoring and Control Scale-Tron Inc. announces a major upgrade of the SiloWeigh. Net inventory management and control system that moni- tors the weight of material in silos or vessels located across a very wide area. The information can be used to predict when deliveries will be necessary, even if the user is not aware of it, and allow appropriate action to be taken. For example, deliveries for the next day can be scheduled rather than react- ing to urgent phone calls. In addition, the system is claimed to eliminate shutdowns due to empty silos as well as overfill and its environmental consequences. Temperature compensated bolt-on strain-gauge sensors on the vessel’s legs or skirt send data via a digital transmitter at each vessel to the local area computer network, where graphical displays can be viewed on any computer. An overview shows all silos at the location and individual trend graphs can show the usage and refill patterns on any silo. Data is also transmitted via the Internet or, when Internet is not available, the cellular radio network, to the SiloWeigh.Net main database. This database allows data retrieval via a secure Internet site to show levels in all silos as well as trend graphs and alarm logs. Scale-Tron Inc., St. Laurent, QC, Canada 514-940-0337 www.siloweigh.net Ultra-Heavy-Duty Bulk Bag Filling System This new ultra-heavy-duty bulk bag fill- ing system palletizes and fills bulk bags with filter cake, aggregates, metal powders, abrasive minerals, dry chemical additives, and other difficult-to-handle bulk materials. The system integrates a Swing-Down bulk bag filler with a Flexicon pallet dispenser and powered chain conveyor, allowing safe, high-capacity filling of bulk bags of all popular sizes, including bags with wide- diameter spouts for passage of irregular materials. When a filling cycle is initiated by push button or contact closure, pallet dispenser forks lower the stack of pallets onto the chain conveyor, withdraw from the bottom pallet, and raise the remaining pallets, allowing the conveyor equipped with photoelectric eyes to move the dispensed pallet into position below the filling station. The bag connection frame of the Swing-Down fill head lowers and then pivots to a vertical position, allowing an operator at floor level to safely and quickly attach bag straps to automated latches, slide the bag spout over a wide-diameter inflatable spout seal, and press a spout seal inflation button. Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com Dual-Use Packaging System PDC International Corp., a world leader in the development and manufacture of shrink sleeve applica- tors and sleeve labeling systems, has introduced the 65 Series Shrinksealer. The newly re-engineered 65 Series was developed for continuous production environments. The equipment is ideally suited for shrink sleeve labeling, which involves full-height body sleeve labels with primary graphics. Used this way, the sleeve label can extend over the cap, with a horizontal perforation for tamper evidence on jars, bottles, and other containers. The machinery also performs tamper evident banding around the upper portion of a container and its closure, and applies full-height safety seals for vitamins and similar products. The machine operates at 50 to 175 cpm (containers per minute) with maximum speeds dependent on package dimensions. Sleeve diameter range is .375 to 3.25 in. Sleeve height range is .625 to 8 in.

    8 August2014 IndustryInsight P Understanding the Long-Term Valueof Dust Collection System Investments Travis Haynam trahay@uasinc.com Performing a lifecycle cost analysis is often an over- looked step in evaluating the purchase of a dust col- lection system. Too often, focus is given only to the initial purchase price of the equipment versus deter- mining the ongoing expenses associated with operat- ing and maintaining the system. Perhaps the reason for this approach is that many companies do not com- pletely understand the relationship between proper dust collection system design and configuration or its impact on operational costs. Many of those initial design decisions and configuration choices make the difference between an effective solution which is a sound return on investment or an inefficient system that drives up operational expenses. If not properly designed, the expenses to operate and maintain a poorly configured system will rapidly exceed the initial purchase price. The most expensive aspect of the dust collection system is the energy re- quired to operate the air moving device. Therefore, investments that minimize the horsepower requirement, such as reducing the required airflow volume and operating static pressure, will yield significant long-term savings. Some steps that will decrease the power requirement include having favorable inlet and outlet conditions or utilizing an airfoil fan wheel to allow the blower to op- erate more efficiently. Incorporating variable frequency drives (VFDs) is an ad- ditional investment that can significantly reduce the blower operating expense up to 30%. Implementing poor duct design practices or selecting less than ideal duct ma- terials will also negatively impact operating costs. For example, choosing to use long sections of spiral duct or flex duct versus smooth duct may save money on the initial material cost but long term, the additional friction added to the system will increase the static pressure loss requiring additional horsepower to maintain the desired performance. Upgrades to the hood design such as a flanged or bell mouth hood will result in improved contaminant capture while reducing system energy requirements. Most dust collection systems utilize a reverse pulse jet arrangement to clean filters and maintain system operating pressure. The associated energy costs of these compressed air systems are another important cost to consider. Taking steps to minimize cleaning frequency or choosing equipment which is more effective per cleaning cycle are essential for controlling ongoing costs. Incorporating an on-demand pressure controller that only cleans the filters as necessary is also a sound investment that can further reduce longer term oper- ating expenses. Choosing filter technology such as nanofiber that incorporates a surface loading layer which improves the effectiveness of a cleaning cycle will decrease the cleaning cycle frequency and lower maintenance costs. Considering the lifecycle costs of a dust collection system investment is es- sential in order to realize the full system value and maximize return on invest- ment. Working with specialists within the industry who understand the impact design can have on long term operating expenses as well as the value of prop- erly configuring the system to match the process and application requirements will yield significant savings over the life of the system.

    14 August2014 TechnicalExclusive caption C Choosing Cartridge Dust CollectorFilters for Processing Applications Cartridge dust collection systems are the preferred technology for most dry processing applications today, and there are many different pleated filter cartridges available for these collectors. As you face stricter air quality and combustible dust regulations, coupled with tighter internal cost controls, choos- ing and using the best dust collector filter for your process is more important than ever. Making an in- formed choice can improve your collector’s dust cap- ture efficiency and reliability while reducing energy and maintenance requirements. Types of Filter Media There are two basic categories of media commonly used in pleated cartridge filters. The choice is usu- ally driven by dust type, operating temperatures, and the level of moisture in the process. 1. Nonwoven cellulosic blend: This media is the most economical choice for dry dust collection ap- plications at operating temperatures up to 160°F. Sometimes the fibers will incorporate a coating that en- hances moisture resistance. However, cellulose media as a category are not as resistant to moisture as synthetic poly- ester. 2. Synthetic polyester me- dia or polyester-silicon blend: This lightweight, washable media can handle dry appli- cations with maximum oper- ating temperatures ranging from 180°F to 265°F. These filters are washable and can recover from a moisture ex- cursion but are not intended for wet applications. Either type of media can be treated with a layer of nano fibers that boosts the efficiency and yields other benefits as well. Nano filter technology has advanced in recent years, and the newest generation of nano fibers can perform well even in the most extreme conditions. When a layer of nano fibers is applied on top of the base media - whether cellulosic or polyester - the nano coating promotes surface loading of fine dust, preventing the dust from penetrating deeply into the filter’s base media. This translates into better dust re- lease during cleaning cycles and lower pressure drop readings through the life of the filter, which, in turn, promote longer filter life as well as energy savings. Standard and nano filter media can also be treated with compounds that deliver special performance properties. Flame-retardant media are treated with a chemical that provides fire retardant properties for use where there is a risk of fire or explosion. Companies involved in metalworking processes such as plasma and laser-cutting, grinding, or welding commonly use filters with flame-retardant media. Conductive or anti-static filters may be used where conveyed dusts generate static charges that require dissipation. Typically, static dissipation is achieved by impregnating a cellulose filter with a carbon coat- ing or a synthetic filter with an aluminized coating. Applications for these filters include fumed silica dust, plastic, PVC, or composite dusts, and carbon black/toner dusts. Cartridge filters with anti-static media can also be used in explosive dust applica- tions, making it possible to conform to NFPA re- quirements and lessen the risk of ignition sources due to static electricity charges. In combustible dust applications where the minimum ignition energy of the dust is below 3 millijoules (mJ), the NFPA requires the filters to be conductive, bonded, and grounded to the filter housing. Selection Tips Following are five tips that can further help you de- termine the best filter for your application: 1. Understand the different measures of filter effi- ciency and how to apply them. There are two meth- ods that dust collector filter manufacturers typically use to express filter efficiency. Gravimetric analysis is based on particle capture by weight: For example, filter efficiency might be stated as 99.995 percent on particles of 0.5 µm or larger by weight. Filter efficiency may also be expressed as a Minimum Efficiency Reporting Value, or MERV, based on a scale from 1 to 16, with MERV 16 being the highest efficiency. By Rick Kreczmer, Camfil APC Conductive (anti-static) filters may be used where conveyed dusts generate static charges requiring dissipation.

    www.PowderBulkSolids.com 15 August2014 The MERVscale was developed for the HVAC filter market and does not take into account the way a dust collector operates (i.e., it pulse-cleans filters periodically when a dust cake builds up). Though MERV and gravimetric efficiency ratings are useful tools for comparing filters, you should not rely on these measures alone to determine efficiency. It is more relevant to make sure you are satisfying OSHA or EPA re- quirements for filter performance – OSHA if you are discharging the air and recirculating it indoors downstream of the collector, the EPA if you are discharging the air outside or into the environment. Mass density efficiency, defined as the weight per unit volume of air, is the best predictor of a filter’s OSHA compliance. For example, OSHA might require that emissions will not exceed 5 mg/cu m at the discharge of the dust collector. Similarly, the EPA doesn’t care about percentage efficiency claims; they want to know that emissions will be at or below required thresholds, typi- cally stated as grains per cu ft or mg/cu m. Concerned about which effi- ciency measure(s) to use? If so, you are not alone. But there is a way to cut through the confusion and make sure your bases are covered: Require your filter sup- plier to provide a written guaran- tee of performance stating that the filters you select will satisfy applicable OSHA or EPA require- ments. It is worth noting here that ASHRAE is developing a new standard specifically for measur- ing performance of dust collector filters. Finalization of that stan- dard, however, is at least a couple of years away. 2. Test your dust. The collec- tion and testing of dust samples is a long-established practice used by processing professionals to make informed dust collection decisions. While dust testing has always been good practice, it is rapidly becoming a necessity in today’s regulatory climate. There are two types of dust testing: (1) bench testing, which pinpoints physical properties of the dust, and (2) explosibility test- ing, which determines whether a dust is combustible. Bench testing involves a series of tests that provide valuable data for filter selection. Particle size analysis reveals the dust’s par- ticle size distribution down to the submicron range to determine the filtration efficiency needed to meet emissions standards. This test pinpoints both the count (the number of particles of a given size) and the volume or mass spread of the dust. Knowing both is important because many dusts are mixed. A video microscope provides visual analysis of the dust shape and characteristics. Together with particle size analysis, this tool is vital for proper filter selection. For example, a microscope may be needed to detect oil in the dust. Moisture analysis equipment measures a dust’s moisture per- centage by weight, providing information that can prevent moisture problems. A humid- ity chamber is used to see how quickly a dust will absorb mois- ture. This helps to identify hy- groscopic (moisture-absorbent) dust which requires widely pleated filter cartridges, as these sticky dusts cause filters to plug. Additional bench tests can help to determine the optimal design of other dust collection system components. It is not necessary to bench-test dust 100 percent of the time, but if there is anything at all unusual about the process and/or the dust, it’s a good idea. To determine whether a dust is combustible, it should undergo separate explosibility testing as stated in NFPA Standard 68. If a dust sample is not available, it is permissible to use an equiva- lent dust (i.e., same particle size, etc.) in an equivalent application to determine combustibility. But once the dust becomes available, it is still recommended that you go back and test the dust using either the 20-l test method de- scribed in ASTM E1226-12a or the similar method described in ISO 6184/1. Using your dust sample, the lab will start with a screening test to determine whether the Bench testing identifies physical proper- ties of the dust, aiding filter selection. An engineered test is performed at an official testing facility to confirm that this dust collector can withstand an explo- sive event. Scan QR code to view brief explosion test video. ADVERTISEMENT Wear resistant pipe bends Jason Hunter, Pelletron Corporation Pneumatic conveying of abrasive materials wears out standard, long- radius pipe bends quickly. There are various types of pipe bends designed for extended lifetime available. Pelletron developed a special elbow that withstands the most abrasive materials. Wear problems are common in dilute phase conveying systems with high velocities. The conveyed product slides along the elbow wall at a high velocity and high centrifugal forces press the conveyed material against the outer metal surface. The resulting friction causes the elbow walls to wear out quickly. Pelletron developed a unique, patented conveying pipe elbow that is trade named the Pellbow®. It is especially designed to minimize damage caused when solid particles are injected into a high velocity con- veying system — the higher the velocity, the higher the friction. Using a Pellbow® avoids the problems caused by friction in traditional elbows. P PneumaPneuma radius prad us p designedesign specialspe By design, material flowing through the Pellbow® forms a pocket or “impact zone” and moves slowly upward and out. Incoming material is deflected at 90 degrees with minimum resistance and no impact damage. The Pellbow® is wear-resistant making it the ideal solution for conveying abrasive products. The Pellbow® is self-cleaning when the material flow is stopped and it works in all installation positions. Long-radius elbows or other types of pipe bends in existing vacuum and pressure dilute phase conveying systems can be easily retrofitted with the Pellbow®. The pressure drop compared to long-radius elbows is minimally higher. The minimum product-to-air ratio of 3:1 or higher guarantees best results. The Pellbow® is designed to fit all kinds of pipe and tube connections. The Pellbow® is available in aluminum, stainless steel and cast iron for pipe sizes from 1.5” up to 12”, as well as in surface hardened versions.

    Powder BulkSolids16 TechnicalExclusive August2014 dust is combustible. If the dust is not combustible, testing will stop there. If it is combustible, the lab will conduct further testing on dust cloud parameters to pinpoint the Kst (defined as the deflagra- tion index of a dust cloud, or rate of pressure rise) and Pmax (the maximum pressure in a contained explosion). Explosibility testing is per- formed primarily to help deter- mine what explosion protection or prevention equipment is needed on your dust collector and related components. But it can also play a role in filter selection. For example, testing for the mini- mum ignition energy can help determine if conductive filters are needed. 3. Evaluate total cost of own- ership. When choosing between two cartridge filters with the same rated efficiency, some pro- cessors will regard these items as a commodity and simply choose the lowest-priced filter. But as with most purchasing de- cisions, initial cost is only one factor, and it requires a “Total Cost of Ownership” (TCO) evalu- ation to make the best filter se- lection. TCO helps you determine what it really costs to own your dust collector filters by calculating all the components of true filter cost: energy, consumables, and main- tenance and disposal. A reputable filter supplier should have soft- ware to help you perform the calculations. The TCO evaluation will ultimately save you money, time, and energy by ensuring the most cost-effective filter choice. (Note: A detailed article on TCO appeared in the August, 2010 is- sue of Powder Bulk Solids and can be accessed at www.powder- bulksolids.com.) 4. Consider a nano fiber me- dia even if you do not have a “difficult” dust challenge. When they were first introduced to the market, nano fiber media were regarded as a high-end choice lim- ited to exotic or demanding dust- capture challenges. Though these filters carry a cost premium, their use is becoming more widespread for all types of applications as processors come to understand their benefits. Compared to stan- dard media, nano fiber filters of- fer higher filtration efficiencies as well as better energy perfor- mance, superior cleanability, and greater resistance to wear and tear from pulse-cleaning. Because of these benefits, some filter ex- perts believe nano fiber media will become standard in the fu- ture. As a rule of thumb, if you are looking for high initial filtration efficiency and better release of dust through surface loading, then nano fiber media should be the default choice. Beyond this, even for a “non-high-perfor- mance” application, a TCO analy- sis (above) might be worthwhile to find out if the added cost of nano fiber media will be more than offset by resulting savings in energy and filter change-out and disposal costs. In a system operating at very high airflow, for example, a half-inch reduc- tion in pressure drop achieved with a nano fiber filter can make a huge difference in energy con- sumption. 5. Look for a uniform wide pleat media design. Many filter manufacturers add filter media to the point where the pleats are so tightly packed that when dust gets between the pleats, the re- verse pulse cleaning system of the dust collector will not eject the dust from the pleats. This in- creases the resistance of the air through the filters and diminishes airflow. The key is to use a wide pleat where 100 percent of the media is usable. A wide pleat filter allows the collected dust to release from the filter, keeping the resistance lower through the filter for a lon- ger time. Some wide pleat filters use state-of-the-art technology of synthetic bead pleat separators to ensure pleats are kept wide and open for the best dust release possible. These separators pre- vent the media from folding over on itself, which could cause the filter to plug. A wide pleat filter will often contain less total media area than a tightly pleated model. But the total square footage of the media is not what you want to look for: It’s the total usable media area that’s really impor- tant. Rick Kreczmer has held numer- ous positions with Camfil APC in the U.S. and Europe, and cur- rently serves as aftermarket sales manager.

Kreczmer can be reached at 800-479-6801, 870-933-8048, or filterman@camfil.com. Open-pleated media allows the collected dust to release from the filter, keeping the resistance lower through the filter and extending filter life.

Dust Collection Air Pollution Control ProductFocus Spark Detection and Suppression The pneumatic conveying of com- bustible dusts carries inherent risks for dust fires and explosions in many applications. Grinding, cutting, and drying operations can often cause sparks that are typi- cally the ignition source for fires and explosions in duct collectors and air filtration equipment. The FLAMEX system is specifically de- signed to address these hazards by detecting and suppressing sparks in the pneumatic ductwork before they can reach dust collectors or storage bins. Infrared detectors sense sparks being transported through ductwork to a dust collec- tor. The system then triggers an extinguishing device located down- stream from the detectors and ef- fectively extinguishes the spark.

    Powder BulkSolids18 Editor’sSpotlight August2014 • Pneumatic Conveying Low-Pressure Continuous Dense Phase Convey System for Fragile Material The E-finity is a patented continuous dense phase convey system for fragile materials. Precise pressure monitoring and airflow cor- rections allow the system to operate efficiently under all conditions, while gently inducing materials through the convey line in slug form. E-finity is ideally suited for granular and pel- leted materials, and has proven itself on many projects for pet foods, cereals, nuts, grains, and prills. E-finity air controls can employ a single air source to operate 2-3 different systems si- multaneously. The result is a cost savings in both equipment and installation, with contin- ued savings in operation and maintenance mov- ing forward. Schenck Process, Kansas City, MO 800-821-2476 www.macprocessinc.com Patented ECOPhase Pneumatic Conveying System The patented ECOPhase pneumatic conveying technology uses a specially designed entrainment device called a “Magveyor” to al- low a system to operate continuously while achieving high solids loadings and allowing the conveyor to run more efficiently. This can be of advantage to a manufacturing facility in either of two ways: it will allow a new installation to reduce the horsepower needed to convey dry bulk solids for a given rate and distance, or it will allow an existing installation to run more efficiently on existing horsepower, increasing the maximum throughput for a given line. Smoot Co., Kansas City, KS 800-748-7000 www.magnumsystems.com Batch Weigh Vacuum Convey System Vac-U-Max has supplied a batch weigh vacuum con- vey system that can be used in the food, pharmaceuti- cal, or chemical industries. This system is designed to deliver powders and granules to your process ves- sels with a high level of accuracy - with ½% of the batch size. This type of vacuum convey system allows for greater control of product quality and inventory control of materials. Material can be conveyed from drums, bags, or super sacks. Complete systems are available and the equipment is custom designed for the specific needs of the application. Vac-U-Max, Belleville, NJ 800-822-8629 www.vac-u-max.com Vacuum Conveyors Move Material without Plant Air Hapman’s line of vacuum conveyors convey powders, granules, flakes, and pellets up to 18,000 lb/hr. The convey- ors are engineered with a PD pump or regenerative blower to create vacuum without the need for plant air, increas- ing energy efficiency and lowering oper- ating costs.

These vacuum conveyors move products vertically, horizontally, around corners, on multiple levels, and long distances with minimal opera- tor attention or maintenance. They are ideal for conveying powders, dusts, granules, flakes, and pellets in continuous or batch processes. Hapman, Kalamazoo, MI 800-427-6260 www.hapman.com Mini-Fluidizer Promotes Material Flow Solimar Pneumatics has added a smaller version of its disk-type fluidizer. This 2-in.-diam Mini Disk fits in pipes, chambers, chutes, and small hoppers to enhance flow of powders and dry bulk mate- rial in pneumatic conveying systems. Because of its compact size, the Mini-Disk fits in curvatures as small as 4 in. In all applications, these fluidizers prevent bridging, rat holing, and material hang-ups. The aeration of the disk fluidizer utilizes directional air flow along the wall of the chamber or pipe to loosen product and move it to the discharge point. Gentle vibration is provided at the outer edges of the disk to keep powders and bulk solids flowing. Because the disk seals tightly against the chamber or pipe wall, there is minimum back pressure. This design advantage also prevents airline plugging. All Solimar aerators are compatible with food grade materials and are FDA approved. Solimar Pneumatics, Minneapolis, MN 800-233-7109 www.solimarpneumatics.com Pneumatic Conveying of Highly Caustic, Corrosive Material Specially treated to transfer a highly corrosive, granular material, this pneumatic conveying system uses integrated automation to mini- mize human exposure to the material and to optimize process efficiency with the upstream bulk bag unloading system.

    www.PowderBulkSolids.com Editor’sSpotlight 19 August2014 •Pneumatic Conveying Conveying Process for Plastic Production Plants The pellcon3 conveying process pro- vides a solution for plastic processors who are upgrading existing plants or building new ones. This technology consists of the three process compo- nents: Strandphase conveying, Pellbow pipe bends, and the DeDuster for fines removal. Unlike dense phase systems, the pellcon3 process does not create dynamic forces throughout the line, reducing costs for building construc- tion and silos. Maximum conveying pressure is below 22 psi, making use of medium pressure rotary valves and blowers possible, and the flexibility of turndown ratios in a Strandphase system allows operation without an additional air management system. With pellcon3, conveying line sizes are smaller than in dilute phase or dense phase systems, and the efficient use of energy provides additional savings in the ongoing cost of operation. Pelletron Corp., Lancaster, PA 717-293-4008 www.pelletroncorp.com High-Pressure Blowers The conveying of material-laden air with fans involves determining the bulk density of the material to be conveyed. An appropri- ate amount of dilution air will be determined and a fan selected. High-velocity air is used to carry dirt, weld fumes, grain, plastic ma- terials, wood waste, and paper trim from a process to a collection point. BC pressure blowers are designed for high-pressure, indus- trial-process applications. All applications can be handled in either induced-draft or forced- draft configurations. Modifications and accessories make BC pressure blowers suitable for a wide range of systems, especially pneumatic conveying. The New York Blower Co., Willowbrook, IL 800-208-7918 www.nyb.com Food and Pharma Vacuum Conveyor A new conveyor line from Piab, piFLOWp meets the high demand from the food and pharma industries.

All materials are FDA approved and all configurations can be delivered with an ATEX Dust certificate. Piab, Hingham, MA 800-321-7422 www.piab.com Heavy Duty Material Handling Hose Tigerflex Voltbuster is a lightweight, thermoplastic material handling hose that safely dissipates static charge in extremely high-static applications. The Voltbuster hose solves the problem of in- dustrial hose propagating brush discharge, otherwise known as “hose arcing,” which occurs when the static generated inside the hose overloads the dielectric strength of the hose tube. The conse- quences of electrostatic discharges range from personnel experiencing serious physiological shock to a potentially fatal dust cloud explosion. The hose can be used at any facility handling powders, plastics, or other granular materials, offering a lightweight alternative to cumbersome metal and industrial rubber hoses. The hose can be used without workers’ fear of getting “shocked,” while at the same time being lightweight and flexible enough to maneuver without worker strain.

    Powder BulkSolids20 Editor’sSpotlight August2014 • Pneumatic Conveying Pneumatic Air-Vey Magnets Air-Vey magnets are designed to remove ferrous contaminants from products in dilute-phase pneumatic conveying systems that operate at 15 psi or less. These units are used to ensure product purity and protect process equip- ment. The flow-through area of the housing is engineered to maintain the same product velocity without an appre- ciable drop in pressure. These magnets install easily in horizontal, vertical, or angled positions with compression-type couplings or via welding in place. Puritan Magnetics Inc., Oxford, MI 248-628-3808 www.puritanmagnetics.com Pneumatic Weigh Filling System This pneumatic gain-in-weight filling system conveys and weighs free-flowing bulk solids, and discharges the material into bulk bags dust-free. The filter receiver of a Pneumati- Con vacuum dilute-phase pneumatic conveying system is mounted on load cells, enabling the controller to stop the flow of material once an accurate batch weight has been accumulated. A “fill” button on the Twin-Centerpost bulk bag filler actuates a blower to remove bag creases, and then opens a slide gate valve to discharge the batch into the bag at high rates, as a vibratory deck densifies the material to stabilize the bag. The filler is mounted on a secondary set of load cells to check-weigh the filled bag. A port within the discharge spout vents displaced air and dust to a remote bag house. The controller then releases the bag straps and deflates the spout seal, allowing the operator to tie-off the spout and remove the filled bag. Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com Rotary Valves Coperion K-Tron offers Heavy Duty (HD), Maximum Duty (MD) and Quick-Clean (QC) Aerolock rotary valves, as well as Light Duty (LD) and Blow-Through (BT) models.

Coperion K-Tron Salina Inc., Salina, KS 785-825-3884 www.coperionktron.com Pocket Elbows The Dense Flow Pocket Elbow is designed for use on pneumatic conveying pipelines, and is most effective when highly abrasive materials are being transported. During a pneumatic convey cycle, the elbow traps incoming material at the elbow’s deflection point. The material that is trapped in the “pocket” then acts as a barrier for any remaining material being conveyed, and greatly increases the lifespan of the elbow. The Pocket Elbow can directly replace any existing pneumatic elbow when combined with Dense Flow Pipe Stubs. The advantages of the Dense Flow Pocket Elbow are increased elbow lifespan, less downtime, lower maintenance costs. JDB Dense Flow Inc., Palm Harbor, FL 800-822-3569 www.jdbdenseflow.com Flex Tube Diverters Eliminate Cross-Contamination Vortex Flex Tube Diverters eliminate material cross-contamination commonly found in the food, plastic, and chemical industries. They are ideal to divert, or converge, a wide range of dry mate- rials, including sugar-based solids, in gravity or dilute phase pneumatic conveying systems. Flex Tube Diverters feature two or three ports that utilize a basic sliding orifice blade design. A tube stub is welded to an orifice-style blade, and a flexible hose is then attached to the tube stub. As the diverter blade is shifted, a flexible hose moves from one port to the other, allowing the con- venience of continuous conveying. When one port is open, the other ports are sealed and elimi- nates any internal ledges or pockets where material can become lodged and remain trapped.

    www.PowderBulkSolids.com Editor’sSpotlight 21 August2014 •Pneumatic Conveying Dense Phase Pneumatic Conveying Systems Dynamic Air pneumatic conveying systems handle a wide range of materials and bulk densities at rates from 500 lb/hr to 450 tn/hr, over distances to 6000 ft. Each system is custom-designed from one of 16 different conveying concepts to provide a conveying solution that fits the process perfectly. One conveying concept, the Full-Line Concept system, has many advantages over more traditional dense-phase concepts with regard to degradation and energy consumption. In addition, it is clean and totally enclosed and can be fully automated to convey to packaging or process bins. Few moving parts are utilized, as the prime mover is standard plant compressed air at 100 PSIG. Cross contamination is never an issue as the convey- ing line can be purged clean when switching between materials. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com Blow-Through Feeder/Airlock Fine powders can easily over-aerate, which reduces material feed efficiency in high-pressure pneumatic conveying applications. ACS Valves designed the BT Series blow-through feeder/ airlock to ensure optimal throughput of hard-to-convey materials. The BT Series 12-vane rotary valve design decreases excess aeration of the material during conveying with an integrated vent port on the return side of the valve housing that vents pocket air leakage. The BT design element minimizes the flow path of air through the rotor clearances, improving ma- terial pocket release. With minimal air leakage, the resulting low, effective pressure drop of the BT Series optimizes ma- terial flow density, improves material conveying efficiency, and reduces total compressed air consumption.

    24 August2014 TechnicalExclusive Figure 1 -Dust Explosion Pentagon I Secure Cloud-Based Industrial Monitoring Solution It is well known that transporting certain dry dusty materials can create explosive atmospheres. Five conditions, known as the “Dust Explosion Pentagon”, have to exist in order for the explosive state to oc- cur. First, there needs to be a high concentration of dust (fuel), followed by an ignition source (heat) and oxygen (oxidizer). If all of these appear in a confined space with dispersion, an explosion can occur. The most common ignition sources have long been iden- tified as over-heated bearings, misaligned belts, and belts that are slipping. The industry is saturated with various sensors and controllers that monitor these conditions to prevent explosions. Regardless how well these systems work there is one problem with all of them: human error. With the ever-growing demands on site performance and efficiency at ter- minals and processing facilities, decisions to bypass safety equipment has become an ever increasing is- sue. With mount- ing pressures, site personnel may risk keeping a machine in opera- tion even after an alarm has been detected, putting the plant and all personnel at risk. Without backend reporting systems and data logging, this dangerous practice can go on undetected by up- per management. In order to combat this issue, 4B Components has developed a solution that in- troduces a greater level of transparency and record keeping. HazardMon.com is a secure cloud-based industrial monitoring solution that allows any regis- tered user to log in and see all their facilities in real- time from anywhere in the world. This product of- fers seamless integration with 4B’s T500 Elite Hotbus hazard monitoring system.

All sensor data can be viewed in real-time using any standard Web browser such as Mozilla Firefox, Google Chrome, or Internet Explorer (see figure 4). The Web site is completely dy- namic and the sensor status and value are updated automatically without the need to refresh the webpage. The Web site was de- signed to dynamically resize as the screen resolution changes and it is optimized for tablet and mo- bile phone platforms. Historical Data Analysis All data can be viewed as graphs. A unique drag-and-drop feature allows you to pick specific sen- sors of interest and compare them side-by-side in one graphical view (see figure 5). Time windows can be selected, ranging from 1 hour to 30 days. The graphs are inter- active, allowing you to use your cursor to mouse over any event to show specific values and sen- sor statuses. All alarms are stored in a sepa- rate alarm log (see figures 6 and 7). Using the Web site filtering options, it is easy to generate a report and download it into a standard spreadsheet program. All the alarms are grouped into different alarm types, like “Alarm Detected”, “Alarm Cleared”, “Device Power Up”, etc. This al- lows information to be extracted in a few clicks and create a report in seconds. Email and Text (SMS) Notifications Engine A flexible notification system al- lows any user to receive email or text message notifications. Notification can be sent when sensors go in and out of alarm; when the Internet connection between the T500 Hotbus system and the server is lost or when an alarm has not been cleared for a number of minutes. It is also possible to receive notifications only when an alarm has not been cleared for a specified number of minutes. Report Generation Tool An advanced analytics tool allows reports to be generated that sum- marize the safety and efficiency of the factory. Currently it is pos- sible to see which sensors caused the majority of alarms, which hours of the day had most alarms, and the types of alarms.

    Powder BulkSolids26 TechnicalExclusive August2014 dates of reports can easily be al- tered and the report re-generated. Reports can be saved to the user’s PC in a single click. Automated Maintenance and Testing Functionality It is important to periodically check that your monitoring sys- tem will detect an alarm when a dangerous condition occurs. The current standard in the industry is for technicians to walk around the site and manually test each sensor. A paper report is then generated and in some cases, converted into a digital format (Microsoft Excel for example). There is still absolutely no guar- antee that the technician actually performed any of the testing. HazardMon’s sensor testing func- tion ensures that test procedures are carried out, logged, and re- ported within the system. This feature provides managers docu- mented evidence that each sen- sor has been tested to ensure it is working correctly. (See Figure 10). To initiate a system test, a user would go to the “Maintenance” tab within HazardMon.com and choose a sensor to test. During testing, HazardMon temporarily stops alarm notifications for this sensor, so that no nuisance alarm notifications are sent out. The user has five minutes to trigger an alarm and confirm the sensor is in proper working condition or needs to be replaced. The whole process is logged automatically, and a maintenance report can be generated after testing has been completed. Conclusion As more facilities install moni- toring systems to ensure the site’s safety, the main safety concerns, human error, and the lack of transparency still exist. HazardMon.com combined with 4B’s hazard monitoring systems gives management real-time ac- cess to all critical monitoring data. This increases transparency, cuts down on human error, and helps to verify that company safety poli- cies are being adhered to.

Freeman Technology, Tewkesbury, UK +44 (0) 1684 851 551 www.freemantech.co.uk Compact Vibrating Rod for Small Bins BinMaster introduces the new CVR-625 mini vibrating rod, a compact point level control designed for use in small bins and hoppers where other level sensors will not fit. The new ver- sion features an updated design that allows for the detection of light materials with a bulk density as low as two. The rod can be used for measuring plastics, food, seed, chemicals, and other pellets or dry granular solid materials. The signal from the elec- tronic circuit of the CVR-624 excites the single rod of the instru- ment to vibrate on its resonance frequency of approximately 460 Hz. When material covers the rod of the probe, the vibra- tion stops. This is sensed by the electronic circuitry that forces its output relay to switch. When the blade becomes uncovered, the vibration will restart and the relay will switch back. Due to its vibrating technology, the mini vibrating rod is able to over- come the difficulties associated with changes in dielectric con- stant, humidity, temperature, and material density, and elimi- nates the problem of false signaling due to material wedging and buildup associated with Ôtuning forkÕ type probes.

    30 August2014 TechnicalExclusive caption O High-Tech Plastics Are Economicaland Environmentally Friendly One of the greatest advantages of plastic is that it can replace heavier metal – resulting in more light- weight automobiles. DuBay Polymer GmbH is one of the world’s largest plants for the production of high- tech plastic. During the refinement process of com- pounding, a variety of dusts and fumes are created that must be reliably extracted. DuBay Polymer in Hamm-Uentrop annually pro- duces up to 80,000 tons of polybutylene terephthal- ate (PBT). The polymer is the primary component of premium plastics that are utilized in numerous in- dustries because of their flexibility. DuBay was estab- lished in 2001 as a joint venture between LANXESS and DuPont and has been experiencing steady growth in recent years. Lighter Plastics Trend A driving force behind this development is the current trend toward replacing met- als with durable and versatile high-performance plastics, or utilizing both materials as a composite (hybrid technol- ogy). “One advantage of plastics compared to metal is the fact that the components are lightweight, resulting in lower fuel consumption, lower costs for the auto- mobile owner and reduced CO2 emissions. A significant advantage for the budget and for the environment,” stresses Michael Pasch, the materials processing engineer responsible for the com- pounding system. By adding a bulking agent, fibers, and other additives, the PBT polymer achieves certain targeted character- istics in such a treatment process. DuBay employees can produce plastics sturdy enough for use as compo- nents capable of withstand- ing heavy use loads such as hinges, housings, heavy foot traffic, or ease of access de- vices. “Because of their heat resistance, automotive suppliers also utilize these plastics in components which are subjected to high temperatures, such as headlight mounts,” adds Pasch. Dual-Stage Separation Technology In the beginning of 2012, DuBay introduced a second compounding system and thereby doubled its capac- ity for high-end plastics. During the planning stages, the system operators requested improvements to the existing labor-intensive extraction process. The key recommendation was provided by Lanxess, the parent company, which has experienced long-lasting results with Keller separators, especially for plastic refinement processes. The requirements of Pasch and his colleagues are consistent with the two-part filtration technology used by Keller for compounding processes. “First we separate dry dusts created during the weighing, mixing, and addition of additives by utilizing a dry separator. Then, any adhesive aerosols released dur- ing extrusion processes are separated by a wet sepa- rator,” explains Nick Herfurth, vice president of sales and operations at Keller. Decreased Sludge Facilitates Disposal There is a frequent risk of deposit buildup and fires inside the ductwork. To offset this risk, Keller employs spray nozzles that rinse the dirty air duct with water over the entire surface. “The evaporative cooling creates a sudden temperature change which results in the condensation of high boiling point solvents,” says Herfurth. The subsequent wet separa- tion removes liquid in addition to solid particulate from the exhaust flow and separates them from the waste water in the sedimentation basin. The result- ing sludge is discharged automatically and continu- ously by a sludge remover and sinks into an adjacent disposal container. “We are pleased that we no lon- ger remove the sludge manually – the operation is now much simpler and a cleaning is seldom neces- sary,” Pasch adds. “The fact that dust generated at the mixing platforms is extracted by a separate dry separa- tor further reduces the amount of sludge that ac- cumulates in the wet separator,” says Pasch. “This facilitates disposal and is more economical. In ad- dition, the dry separator is very easy to maintain. The filter element cleaning is controlled automati- cally by differential pressure or at pre-set time intervals. Full disposal containers can be emptied during operation. The level monitor indicates –Keller dry separator Vario ES465349_PB1408_030.pgs 07.15.2014 03:34 UBMblackyellowmagentacyan

    www.PowderBulkSolids.com 31 August2014 normally afteran interval of some weeks – that the container can be emptied. Dry Separation Process Must Meet ATEX Guidelines The requirements of the ATEX guidelines apply to the operation of a compounding system (explo- sion protection guidelines of the European Union). The Vario dry separator is equipped with a high- quality pressure relief valve that can flamelessly absorb any energy created in the unlikely event of an explosion. One of Keller’s pat- ented back pressure flaps can pre- vent the spread of the shock wave and flames into the workplace. Reliable Filtration Provides System Reliability Pasch and his colleagues manage the compounding system from their control station. A number of monitors and displays assist them. “We only leave if a mal- function message is displayed and this rarely occurs,” says Pasch. The high reliability not only fa- cilitates the operator’s work, but also boosts the rate of produc- tion. “The separation operates smoothly nearly without supervi- sion,” says Pasch. When asked if Keller would be considered for the potential purchase of a third compound- ing system Pasch said, “Keller is one step ahead as far as filtra- tion technology is concerned. Of course they would be in conten- tion.” For more information on Keller USA Inc. (Fort Mill, SC), call 803-396-2000 or visit www.kellerusa.com. High-tech plastics are usually delivered as granulate.

    Powder BulkSolids32 Editor’sSpotlight August2014 • Storage Disk-Type Fluidizers Solimar offers disk-type fluidizers for the discharge of powders and bulk solids. This complete line offers long- wearing aeration devices for many applications including silos, hoppers, bins, and trailers. The fluidizers are particularly effective at preventing rat-holing and bridging by utilizing air pressure to move the material while gently vibrating the vessel wall. The company’s products are divided into two distinct application areas. Silo products include a line of disk aerators that enhance the flow of powders in various storage devices, and transportation products including disk aerators designed for dry bulk trailer usage. Features include: superior sealing properties; optimized air volume to better unload silos or trailers; an original durable design, in two diameters (2 and 4 in.), that will not crack, wear prematurely, or clog like fabric pads; FDA-approved ma- terials with operating temperatures up to 450ºF; and a metallic detectable version for food applications. Solimar Pneumatics, Minneapolis, MN 800-233-7109 www.solimarpneumatics.com Side Door Bin Used primarily in the food and chemical industries for discharging large volumes of dry products, the side door bin features a large door opening that allows product prone to bridging to discharge quickly and completely. This new gasket-free door design makes this container an even more economical choice for handling dry materials with op- tions of stainless, carbon steel, or aluminum construction, and capaci- ties up to 100 cu ft. The stackable bins are combined with a discharge station to automatically tilt bins to 45 degrees. Custom Powder Systems, Springfield, MO 417-868-8002 www.custom-powder.com Rolled, Tapered-Panel Tanks The best features of bolted and field- welded tank construction have been combined in the rolled, tapered panel (RTP) design. Field construction is ac- complished utilizing a synchronized, hydraulic screw jack process that keeps field crews on the ground. This process receives the highest industry ratings for quality control and safety in the field. Tank Connection designs, manufac- tures, and installs all four types of steel storage tanks, including bolted RTP, field-weld, shop-weld, and hybrid tank designs. Tank Connection, Parsons, KS 620-423-3010 www.tankconnection.com Silo Sweep Auger The new Silo Sweep Auger from Guttridge Ltd is a robust machine for the automated emptying of grain silos. Grain silos empty under gravity but as grain lev- els drop this process stalls. One option is to dig out the residual volume manually, but this incurs substantial labor costs and raises HSE issues. The alternative is to use a sweep auger, which as the name suggests, sweeps across the silo floor, transferring the remaining grain via a screw to the silo outlet. The Silo Sweep Auger is made from galvanized steel to improve longevity and reduce the risk of product contamination from flaking paint. Rubber blades ensure an efficient sweep of the silo floor while an enclosed clutch and motor mechanism prevents grain ingress and subsequent damage, improving reliability. The patented drive design delivers the very highest levels of efficiency by reducing slip and strain within the system.

    www.PowderBulkSolids.com 33 August2014 TechnologyReview Dust Collection Air Pollution Control ProductFocus SpaceSaver High-Efficiency Dust Collector The SpaceSaver dust collector is up to 75% smaller than tra- ditional dust collectors, offering long-lasting, leak-free cartridges. With a footprint as small as 27 x 38 in., the SpaceSaver is suited for applications with limited space re- quirements in terms of both cross- section and overall height, as well as in areas of the plant that aren’t connected to central dust collec- tion systems. Many cartridge styles are available to best fit the appli- cation, with sizes ranging from 2 to 48 cartridges per collector. The SpaceSaver uses directed air flow fire to pulse the cartridges. Schenck Process, Whitewater, WI 262-473-2441 www.schenckprocessinc.com Modu-Kleen Downdraft Series Dust Collector The Modu-Kleen downdraft dust collector contains fugitive dust. The air enters at the top of the dust collector housing and flows downward to the cartridge filters, improving the filtering process and the material-to-air ratio. Air veloci- ties are lower than those with a conventional dust collector, reduc- ing the load on each filter car- tridge and extending filter life. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com High-Temperature Wax Technology for Induction Seal Liners Tri-Seal has introduced a high-temperature wax technology designed to bolster the stability of two-piece induction seals that are stored or distrib- uted in challenging high-temperature conditions. The solution is specifi- cally engineered to reduce costly (and potentially dangerous) seal-related product leakage from packaging closures. This is a particular cause of concern for lined closures and seals shipped or stored in high-temperature conditions, such as those found in India, Israel, Southeast Asia, Australia, Puerto Rico, and Latin and South America, as well as southern American states and, more seasonally, throughout greater North America. When exposed to high temperatures even for brief periods, the wax component of a two-piece induction seal can be prematurely absorbed into the pulp layer prior to closure application, thereby potentially compromising seal integrity during the filling and capping process. Often, the result is a “potato-chip effect” whereby the heat seal portion of the circular seal’s outer edge curls and separates from the backing material. During capping, the heat seal portion can fold under and not fully seal on the bottle finish. The ensuing leakage is a particular problem for companies who manufacture and distribute highly sensitive or unstable products, such as those found in pharmaceutical, agricultural, chemical, and au- tomotive industries.

    Powder BulkSolids34 Editor’sSpotlight August2014 • Particle Analysis Morphologi G3-ID Characterizes Discrete Particle Populations within Powder Blends The Morphologi G3-ID from Malvern Instruments is a powerful particle characterization system that combines automated imaging with Raman spectroscopy. Using these technologies, it delivers component specific particle size and shape distribution data for discrete populations within a powder blend. One application is in the analy- sis of environmentally friendly cements, where a proportion of clinker is replaced with ‘waste’ materials, such as blast furnace slag or fly ash. For most cements, laser diffraction particle sizing meets routine analysis re- quirements. However, for cements containing replacement materials it is often necessary to measure the particle size of individual compo- nents within the blended product. Morphologi G3-ID provides statistically relevant particle size and shape data for each component, even where these are morphologically similar. These data are helping manufacturers optimize the performance of newer cements and manage development and future production costs. Malvern Instruments Inc., 508-768-6400 Westborough, MA www.malvern.com Particle Insight Size and Shape Analyzer Particulate Systems’ Particle Insight is ideal for ap- plications where the shape of raw materials – not just the diameter – is critical to the performance of the final product. The instrument offers up to 28 different shape parameters analyzed in real-time in either aqueous or organic solvent suspensions. The Particle Insight operates in a range suitable for a wide variety of industrial, biological, and geological specimens from 1 to 800 micrometers. Its unique recirculating sample module and precision optics are designed to acquire and report statistically valid measurements quickly, an essential quality con- trol capability in many manufacturing processes. Particle Insight features include the ability to track sample shape changes over time as well as the capability to store a collection of particle images. The user has the option of viewing only those particle images that meet any combination of the analyzer’s 28 shape parameters. It also has an automated fill-and-rinse feature allowing for true unattended operation.
