The document discusses spiral classifiers, which are used in mineral processing to separate ore slurries by particle size. It outlines several key variables that must be balanced for effective classification, including the angle of the inclined bed, speed of the rakes or spirals, slurry density, tonnage throughput, and ore settling rate. All of these factors, as well as the ore characteristics, will determine how well a classifier performs. The classifiers are also prone to wear issues and becoming overloaded. Proper adjustment and monitoring of the variables is needed to achieve good mineral separation and avoid operational problems.

SIZE REDUCTION AND FACTORS AFFECTING SIZE REDUCTION IN PHARMACEUTICAL INDUSTRYAkankshaPatel55
In the realm of pharmacy, size truly matters! Particle size reduction, often referred to as comminution, plays a crucial role in transforming raw materials into effective and readily absorbable medications. It's like shrinking giants - turning bulky substances into microscopic warriors ready to combat ailments.
Why is size reduction so important? Imagine trying to swallow a whole apple compared to taking a bite. The smaller the pieces, the greater the surface area exposed, and the faster and more efficiently something dissolves or reacts. In the world of medicine, this translates to:
Enhanced drug bioavailability: Smaller particles dissolve quicker and more readily in the digestive system, leading to faster absorption and action of the medication. Think of it as opening wider doors for the drug to enter the bloodstream and reach its target.
Improved drug stability: Smaller particles tend to be more stable and less prone to degradation, ensuring the medication's potency and effectiveness over time.
Uniformity and mixing: Precise size control allows for consistent drug distribution within a dosage form, guaranteeing accurate and reliable dosing.
Tailored drug delivery: Size reduction facilitates the development of specialized drug delivery systems, like inhalers or sublingual tablets, where minute particles are crucial for targeted action.
How is size reduction achieved? A variety of techniques are employed, each with its own advantages and best suited for specific materials:
Milling: Mechanical grinding using ball mills, hammer mills, or jet mills physically breaks down larger particles into smaller ones.
Micronization: Specialized techniques like air jet milling or fluidized bed milling achieve ultra-fine particle sizes in the micron range (1-10 micrometers).
Cryo-milling: Grinding at cryogenic temperatures minimizes heat generation, preserving sensitive drug compounds.
Size reduction isn't just about brute force. Choosing the right technique and particle size depends on various factors, including the drug's physical and chemical properties, desired release profile, and dosage form. It's a delicate dance between effectiveness, stability, and manufacturability.
The impact of size reduction extends far beyond individual medications. It enables the development of innovative drug delivery systems, like controlled-release tablets or transdermal patches, that improve patient compliance and treatment outcomes. It also plays a vital role in research and development, allowing scientists to study drug interactions and optimize formulations at the microscopic level.
So, the next time you pop a pill, remember the invisible giants behind it - the power of size reduction silently working its magic to deliver healing and hope.
Ores are typically sorted to increase the efficiency of other refining processes, by reducing the amount of material to be processed while simultaneously increasing its purity. This module explains the ore separation processes.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

The Variables of these two types of classifiers are The ANGLE of the inclined bed, this is normally a fixed angle the operator will not
be able to adjust it.
The SPEED of the rakes or spirals, the DENSITY of the slurry, the TONNAGE through put and finally the SETTLING RATE of the
ore itself.
To be effective all of these variables must be balanced. If the incline is too steep the flow of slurry will be too fast for the rakes or
spirals to separate the ore. If the angle is too flat the settling rate will be too high and the classifier will over load. The discharge rate
will be lower than the feed rate, in this case. The load on the rakes will continue to build until the weight is greater than the rake or
spiral mechanism is able to move. This will cause the classifier to stop and is known as being SANDED UP. If the speed of the
rakes or spirals are too fast, too much will be pulled, out the top. This will increase the feed to the mill and result in an overload in
either the mill or classifier as the circuit tries to process the increased CIRCULATING LOAD.
The DENSITY of the slurry is very important, too high the settling will be hampered by too many solids. Each particle will support
each other preventing the heavier material from quickly reaching the “bottom of the slurry. This will not allow a separation to take
place quickly. The speed at which the slurry will be travelling will be slow and that will hamper effective classification. Another

variable is the TONNAGE. All equipment has a limit on the throughput that any one is able to process, classifiers are no different.
This and the other factors will have to be adjusted to compensate for the last variable, the ore itself. Every ore type has a different
rate of settling. To be effective each of the previous variables will have to be adjusted to conform to each one’s settling
characteristics.
The design of these classifiers (rake, spiral, screw) have inherent problems, First they are very susceptible to wear, caused by the
scrubbing action of the ore, that plus all of the mechanical moving parts create many worn areas to contend with. The other problem
that these classifiers have is that they are easily over loaded. A over loaded classifier can quickly deteriorate in to a sanded up
classifier. Once that happens the results are lost operating time, spillage and a period of poor Mineral Processing and Separation
performance.
