  3. 3. 4 | BEST OF 2015 | Rubber & Tyre Machinery World DEC 2015| Internal mixer is standard rubber machinery for volume mixing in both tire industry and non-tire rubber industry. When you use one, your most elementary requirement is to calculate the batch weight for your respective mixer model. Because when mixing rubber compounds, you should under-stand that different compounds based on the same polymer might require different batch weights. And different polymers will almost certainly require different batch weights. Here's 7 quick tips for you to fix the batch weight for your rubber mixing. 7 Quick Tips About Batch Weight Calculation For An Internal Mixer Image: Internal Mixer With Hydraulic Ram (Bainite)
  4. 4. | BEST OF 2015 | Rubber & Tyre Machinery World DEC 2015| 1) Theoretical Equation The thumb rule is the theoretical equation W= NV x SG x FF, where W - Batch Wt [kg]; NV - Net Mixer Volume [dm³]; SG - Specific Gravity (density) of the mixed batch [kg/dm³]; and FF= Fill Factor. Generally, most mixer manufacturers share this calculation with you. But remember, what they give you is only a theoretical number. This is only a starting or reference point and you need to arrive at your own mixing batch weight for your compound recipes, following some of the other tips stated below. 2) Net Mixer Volume (NV) Since Internal mixer has a fixed volume mixing chamber, knowledge of the net volume (in liters) is required. This can be obtained from the manufacturer directly or in some cases from their literature for their various models. When the mixer is used regularly (or if you have procured a used-mixer) the effective volume increases due to wear on the rotors and mixing chamber. If not compensated for this inside wear, your batch volume will be effectively too small leading to insufficient ram on the compound, poor dispersion and longer mixing times. Annual measurements of chamber are recommended to update your batch weight correctly. Excessively worn out mixers will have to be rebuilt or reconditioned (Read our posts on mixer rebuilding – Top 25 Things You Should Know to Discuss with Mixer Rebuilder and 17 Essential Questions to Select the Right Rebuilder for your Internal Mixer) 3) Guesstimate the Fill Factor (FF) If you have a Tangential Mixer (aka Banbury) then your FF can range between 0.70 - 0.85. And for a Intermeshing Mixer (aka Intermix), your FF can range between 0.62 and 0.70. Knowledge of the fill factor is necessary because an under-filled mixing chamber results in the ram bottoming out too soon. This reduces the pressure on the rubber stock and increases the mixing time. An over-filled chamber leads to unmixed ingredients staying in the mixer throat. This creates a mess under the mixer when the batch is dumped. For example, NR-rich compounds in an intermeshing mixer has a fill factor of around 0.65 while for the same compound in a two-wing tangential mixer, it is about 0.75. This compound will have an increased FF of about 0.78 for a tangential mixer with our-wing rotors. Each polymer also has its ideal fill factor and that varies again with Mooney viscosity and filler system. For example, NR-rich compounds in an intermeshing mixer has a fill factor of around 0.65 while for the same compound in a two-wing tangential mixer, it is about 0.75. 6
  5. 5. | BEST OF 2015 | Rubber & Tyre Machinery World DEC 2015| Fill factor of a mixer depends on the age of the machine, wear and tear of the rotors and chamber, the rotor type, rotor speed, rotor friction ratio, nature of elastomer, ratio of elastomers/ fillers, mixing sequence, kind of polymers, fillers and individual SG of the ingredients in your recipe, viscosity of ingredients, etc. Generally, the lower the compound viscosity, the fill factor is higher. Hence, we initially guesstimate the FF before stabilizing on the figure later on through actual trials. 4) Estimate the Specific Gravity (SG) of your Compound You can estimate the density of your compound by multiplying the quantity of each ingredient with its individual density (you can get this figure in any compounding handbook or ingredient supplier literature). Sum up your individual results and then divide this number by the total sum (usually phr). The result will give you the estimated density of the compound. (Mathematically, this is the weighted average calculation). For example, lets consider a sample recipe as shown below (I got this recipe from a web search). Calculating, the SG of this Compound mix is arrived at 1.16 (=179.3/155). Image: Kobelco Make Internal Mixers Mathematically, this is the weighted average calculation. 8
  6. 6. | BEST OF 2015 | Rubber & Tyre Machinery World DEC 2015| 5) Know your Internal Mixer Knowing your internal mixer – its capabilities, design features like rotor (tangential or intermeshing), ram (pneumatic with dedicated air supply at the plant or hydraulic), variable speed capabilities of the motor, SCADA, PLC, automation and control features, etc. Rotor speeds are critical because you can use higher speeds at the initial mix and then reduce the rotor speed to allow the batch to “knead” well. This will allow you to get both your dispersion and distribution tasks of mixing right. Hence, when selecting a mixer explore variable speed drives since it give you advantage in your mixing process. Similarly, think of ram pressure. If your ram pressure is too high you will cause excessive heat build up and poor flow of ingredients across the rotor tips. In intermeshing mixers, this will also cause internal pressure within the mixing chamber and might cause mixer failure. If ram pressure is too low, then you will not get the ingredients down into the rotors and this will result in poor mixing. 6) Watch the Ram Action After the above reference calculations are done and mixing initiated; watch the ram action during the mix. The ram should start high, move up and down about an inch or two and bottom out when mixing is complete. Good mixing practice dictates that when the ram bottoms out about 30-45 seconds before the batch is dumped, you can be assured that the chamber is properly filled and mixed compounds will be of high quality. You need to observe the position of the ram by watching the tell-tail rod attached to the top of the ram. Hence, this requires more of practice and experience than theoretical knowledge. If you have a good mixing system with controls and feedback features, you can correlate the position of the ram with the current and rise in temperature – these are important to get an optimized batch size and high quality of mix. 7) Optimize Your Mix Batch Size (...Do Not Maximize) The key to successful mixing is optimizing your mix batch size, and not maximizing. And good mixing is a form of art. Most mixer users want to get the most out of their internal mixer (quite natural!) and they test its capabilities to the full. Finally, when they get poor mixing, they wonder if they have done the right investment! If you try to take your batch size to the upper limits of the mixer's “capacity” as specified in The key to successful mixing is optimizing your mix batch size, and not maximizing. And good mixing is a form of art. 10

The right batch size will be smaller, but your internal mixer throughput is increased by shorter mixing time and thus more batches in the same period. Thus, optimizing your batch weight will allow you to get consistent batch quality and repeatability that are of paramount importance to your (or your customers') downstream processes. The key factors that will influence your mixing optimization are compound formulation, ram pressure, mix procedure, mixing speed and rotor design. Each mixer is different and it would be very difficult to determine the optimized fill factor without actually conducting several mixing trials. Experience is a key to good mixing. Summarizing, when mixing rubber compounds, different compounds require different batch weights. These 7 tips will help you calculate the optimized batch weight for your compounding recipes on an internal mixer quicker. The key factors that will influence your mixing optimization are compound formulation, ram pressure, mix procedure, mixing speed and rotor design. RMW 12
  8. 8. 14 | BEST OF 2015 | Rubber Tyre Machinery World DEC 2015| Should You Do Single-Stage Mixing or Two-Stage Mixing? Image: Bosch Rexroth Have you encountered this often dilemma, “Should I do single-stage or two-stage mixing for my compound; which machinery to use?” – do not be surprised! You are not alone. Single-stage mixing is considered for productivity reasons (and cost- effectiveness). While Two-stage mixing gives a better dispersion of the finer size blacks. And interestingly, for some compounds with high levels of blacks, even three or more mixing-passes may be necessary. Rubber mixing as a subject would have been quite simpler, if we could answer this topic effortlessly. Unfortunately, it is not! Single-stage mixing in an internal mixer is a cost-effective solution but difficult for all compounds. If the compounds have high filler loadings, you may be forced to mix in two-stages due to the high amount of shear and heat generated in the mixing cycle. If you use peroxide cures or are mixing expensive FKM, then you must be even more worried of the batch temperature. Most experts feel two-stage mixing, with short time spans for each of the mixing stages, is helpful.

  10. 10. | BEST OF 2015 | Rubber Tyre Machinery World DEC 2015| One school of thought advocate an open two-roll mill for second-stage mixing because the dispersion of the batch and the mastication is higher (than an internal mixer). Open mills, though slower, are safe for short scorch compounds. A traditional mixing line comprises of an internal mixer above a dump mill then one (or two) mill before the batch off cooling line. Internal mixers are high-capacity rubber compounding machinery. Hence they need to be supported by open mills with advanced features to keep pace with production. The rotors of these mixers operate at high-speed to maximise dispersion of the bulk ingredients and dump the batch at high temperatures. Curatives, blowing agents, etc are added on the open mill and final homogenization happens on the last mill before batch off. Also, adding the cure system on downstream mill eliminates the batch contamination problem from ‘leftover's’ trapped (between the rotor end plates and ends of the rotors) in the internal mixer. These open mills are recommended to have peripherally drilled rolls to take out heat of the compound before adding heat sensitive curatives. Single-stage mixing in an internal mixer is a cost-effective solution but difficult for all compounds. Image From Web 16

  12. 12. | BEST OF 2015 | Open mill mixing is operator dependent and hence quality of compound varies from beginning of shift to end of shift. As compared to rubber mixing in a closed environment, the probability of ‘fly loss’ is high in open mills. Hence, an alternate school of thought propagates second-stage mixing also performed in an internal mixer. This can be at a lower speed, energy and dump-temperature configuration setting on mixer. Single-stage mixing in an internal mixer is possible, when you mix and drop the batch within 120 degree Celsius. The present range of internal mixers have advanced designs to effectively control batch temperature. With many designs and rotor geometries for faster mixing, accompanied by quicker cooling features, mixers like tandem mixers allow traditional two pass to be reduced to single pass cycle.As a side note, if you opt for single-stage mixing with internal mixer; the Intermeshing Type Mixer has the best quality and efficiency. Single-stage mixing is not always cheaper and two-stage mixing is not always better. The best way to decide is to make a cost- benefit analysis between the two processes for the different polymers that you work with. Quantify how much of your product defects are linked to poor dispersion. Analyzing them, you have your customized solution to mix effectively. Summarizing, there is no one best way for all compounds. Your mixing process has to be designed to the polymer; depends on the viscosity of the elastomers used, the quantity of filler, mixing temperature, machinery employed, time at every stage of mixing and desired physical properties for the end use product. If you get your ‘desired’ characteristics in a single-stage mixing, adopt it or wisely opt for two-stage mixing.

  14. 14. | BEST OF 2015 | Rubber Tyre Machinery World DEC 2015| 9 Things About Tandem Technology Your Boss Wants To Know In Rubber Mixing Image: HF Mixing Group 20
  15. 15. 21 | BEST OF 2015 | Rubber Tyre Machinery World DEC 2015| Dr Julius Peter, then Chief Technical Officer at Continental AG patented his idea of Tandem Mixing Technology in 1989. His colleague, G. Weckerle, manager at Continental Technical Rubber promoted this technology at his factory in Northeim, Germany on K2A, K4, K5 and K7 type of mixers. Francis Shaw Co had sole world rights for supply of the intermeshing type tandem mixers. Today, HF Mixing Group (Harburg- Freudenberger Maschinenbau GmbH) are owners of tandem mixing technology by virtue of their acquisitions in the rubber machinery world. Here are 9 key things about tandem technology in rubber mixing you should know to impress your boss. 1. Tandem technology separates the two main tasks in your rubber mixing process viz. dispersion and distribution. Dispersion means breaking down of your solid materials such as the fillers. Distribution involves achieving homogeneity within your rubber mix compound with its different chemicals added. The temperature profile which is absolutely essential for inducing chemical reactions during your rubber mixing process can be better controlled when these two stages are separated. 2. In Tandem technology you interconnect two “mixers” in series, a ram type mixer on top of aramless mixer. Each machinery is optimised to perform one rubber mixing task. Ram type mixer does dispersion well while ram-less tandem mixer does the task of distribution. 3. Your masterbatch produced in the primary ram mixer is transferred without intermediate storage to the ramless tandem mixer below. Here your batch is cooled and finals mixed. At the same time a new masterbatch is prepared in ram mixer above. The upper mixer with ram is preferably (but not necessarily) intermeshing type. As your masterbatch mixing does not involve the addition of curatives or accelerators and is essentially a heating operation, the mixing cycle may be carried out rapidly without any need to cool your mixer before the next mixing cycle. 4. Between the two mixers is a discharge flap and chute which would be closed at all times except when the lower tandem mixer receives the masterbatch dump from above. In Tandem technology you inter- connect two “mixers” in series, a ram type mixer on top of a ramless mixer. Each machinery is optimised to perform one rubber mixing task.
  16. 16. | BEST OF 2015 | Rubber Tyre Machinery World DEC 2015| 5. The mixer below must be intermeshing type to enable self-feed without pressure and work without a top ram. The finals rubber mixing function is usually a shorter process than the masterbatch stage. This means that the tandem mixer has an idle time after the discharge and before receiving the next hot masterbatch. This idle period with the discharge door open allows the tandem mixer to cool. 6. The final mix compound is then dumped into a two-roll mill or a dump extruder and processed in the normal way. 7. When the two tasks of dispersion and distribution are separated, your compound weight is relatively smaller in the larger lower machine. Hence, you can operate this ramless mixer at a higher speed. This improves the quality of your mix because your compound is moved around the mixing chamber more number of times. 8. Excellent cooling water circulation to the mixers is a must in tandem mixing technology. 9. HF Mixing Group expert, Dr Harald Keuter, emphasize that a Tandem mixer improves your throughput rate by up to 25 per cent when compounding with carbon black compounds and can rise up to 100 per cent with silica compounds. Hence you can cut costs and increase output with this technology. Depending on your choice of mixing line, say for a mixing room with five tandem mixing lines and production of approx. 100,000 tonnes of rubber compound annually, he says you save up to one million euros per year. (...And that’s lot of money!!) The population of tandem mixers is higher in the tire industry while its economy of operations is tempting the non-tire rubber industry as well.

  18. 18. 24 | BEST OF 2015 | Rubber Tyre Machinery World DEC 2015| Top 15 Skills Required For an Internal Mixer (or Kneader) Operator Rubber Mixing is a capital and energy- intensive operation. And mixing machinery are the mother equipment. This could be an Internal Mixer (Banbury or Intermix) or Rubber Dispersion Kneader depending on the size of your organization and/or products manufactured. Hence, the cost of errors or omissions is very high when compounding a batch in a mixer. You need a skilled operator. Ever pondered on the skills that make a mixer operator successful? Here is the list of top 15 skills for you to look out in your next successful batch mixer (or kneader) operator hire. 1. Control of Operations Your mixer operator should be able to adjust ram pressure, control the mixing process, set parameters and ensure its completion as per SOP (temperature or time or energy as programmed/specified). 2. Monitoring Operations The most important skill of your operator should be to have a keen eye for watching gauges, dials, or other indicators in the control panel or HMI to make sure the mixer is working properly. He has to ensure that the mixer is kept clean, safety features are functional, upstream and downstream equipment along with all accessories (like cooling water, hydraulic/pneumatic system, temperature control unit (TCU), lubrication system, etc) are ready Image: Bainite

  20. 20. | BEST OF 2015 | Rubber Tyre Machinery World DEC 2015| 3, Active Listening Your operator should be a skilled listener. He should actively listen to the sounds of the mixer and its motor during a mixing cycle; pay full attention to what his supervisor (or you) or his colleagues on the mixing room safety are saying, take time to understand the points being made, and ask relevant questions. 4. Speaking Your operator should be able to talk to you (or his supervisor) to convey information effectively be it to report data /problems/incidents as applicable in a timely manner 5. Reading Comprehension An operating and maintenance manual is normally supplied together with the mixer. This is a crucial document. Again your compounding process may involve specific work related instructions or SOP. Or there could be a training manual in some instances. Your operator should be able to understand written sentences and paragraphs in these documents. Hence, reading skills is very important for a successful operator. It is not necessary (while it is preferred) that they read English, because you could translate these documents to your operator's local language for ease of reading. 6. Troubleshooting, Judgment and Decision Making Your operator is the first point of contact with your mixer in operation. Hence, he should have the experience or knowledge on mixers to determine/read the causes of any operating errors when they occur, judge the gravity of the error and also decide what to do about it – whether to reset the mixer, or escalate to supervisor or raise a service visit request of the manufacturer's engineer. 7. Critical Thinking Operating a rubber mixer requires critical thinking skills because your operator should use logic and reasoning to identify alternative solutions, conclusions or approaches to problems he faces while mixer is in operation. 8. Quality Control Analysis Your operator should have basic skills on quality control with an outlook to meet your set mix quality parameters in every batch. This may involve need for appropriate fine tuning like helping you fix the batch weight, or sending the sample of specified compound /batch in specified form to lab for testing. 9. Social Perceptiveness Emotions could run high in the rubber mixing room. Your operator should display ‘awareness’ of others' reactions and understanding of why they react as they do in The most important skill of your operator should be to have a keen eye for watching gauges, dials, or other indicators in the control panel or HMI to make sure the mixer is working properly. 26
