Freezer mill

YM Series cryogenic mill using external media chilled, at room temperature can not solve the crushed material using external materials to be crushed frozen material grinding technology. By liquid nitrogen, compressed air, air conditioners and other materials from the cold heat exchange.

Crushing principle: the material through the use of the cold source and the heat exchange; to cool the material to brittle state; brittle materials after grinding in the grinding chamber through numerous bodies of impact, shear, friction and finally become small granular, crushed fineness of the material after up to micron level (600 to 2000 mesh). Choice of materials performance under cold seeking, using liquid nitrogen as a refrigerant, such as the minimum cooling temperature can reach minus 196 degrees, the cooling rate is very fast, some require rapid cooling, low temperature embrittlement of the material is preferred coolant. Less demanding on the cooling temperature embrittlement of materials can be used pre-compressed air or air conditioners produce cold and heat exchange material.
