CRYOGENIC GRINDING AND IT’S APPLICATIONS

2012. 1. 17.  Cryogenic grinding usually starts with chips or a fine crumb. This is cooled using a chiller. The final product is a range of particle sizes which are sorted and either used as is or passed on and further size reduction performed .The cryogenic process produces fairly smooth fracture surfaces. Little or no heat is generated in the process.
