Particle Size Reduction for Chemicals/Rubber and Plastics
A cryogenic milling operation is very similar to a normal, ambient grinding operation. It can be set up in many different ways, but the basic components may include: the mill, a cryogenic conveyor, liquid nitrogen flow controls, a liquid nitrogen supply system, and then other supporting equipment common to normal, ambient grinding operations.The first patent related to cryogenic cooling appeared when it was used to cool the grinding wheel [22]. Since then, the cryogenic machining technique was also investigated for difficult-to-machine materials such as titanium alloys, nickel alloys, and composites, which has proven to be a sustainable option.Review on design and development of cryogenic machining setups for heat

Preparing Sample Materials by Cryogenic Grinding AZoM
Cryogenic or cold grinding has proved to be the most ideal solution for these types of samples. This involves grinding aids such as dry ice (-78 °C) or liquid nitrogen (-196 °C) that are capable of embrittling the sample by cooling and making it break more easily. An additional advantage is that the volatile components of the sample can The cryogenic method has the following advantages over the room temperature methods (i.e., when the rubber is in an elastic state): significantly less energy consumption for mechanical grinding; exclusion of fire and explosion hazard; production of a finely dispersed rubber powder with a particle size of up to 100 microns; elimination of A Multifaceted Approach for Cryogenic Waste Tire Recycling

Trends in Grinding of Agroindustrial Products-A Literature Review
Conclusion: It is observed that engineering texts dealing with theoretical and analytical food milling operations do not emphasize the new trends found. As a complementary part of this study, eight patents related to cryogenic grinding in food were analyzed, identifying uses of this type of grinding in coffee, lipids, lycopene, proteins, grainsNormal grinding processes which do not use a cooling system can reach up to 200°F. These high temperatures can reduce volatile components and heat-sensitive constituents in herbs. But cryogenic grinding process does not damage or alter the chemical composition of the plant in any way. Materials which are elastic in nature, Cryogenic grinding PPT SlideShare
