The whole cryogenic grinding process can be divided into three stages: (1) coarse grinding, (2) precooling, and (3) fine grinding. The cryogenic grinding starts with coarse grinding of dried herbs or spices in normal- or low-temperature condition. Coarse grinding due to very less friction does not generate much heat, and hence the …

theory". Bond's model is most commonly used to describe primary and secondary grinding to product sizes above, for example, 100 µm. Operators sometimes use Bond's equation to describe grinding in situations where it is not appropriate, such as fine grinding below 50 µm. Using an alternative model would be a better choice in this situation.

What Is Grinding and Its Working Principle and Type?
Grinding uses extremely fine micronized abrasives, and the machine tool, grinding tool, and workpiece are in an elastic floating working state. Under the action of low speed and low pressure, the convex points of the processed surface are successively ground, and the processing accuracy can reach 0. 1μm～0.01μm.
