December 16, 2019. Cryogenic grinding permits heat-sensitive, thermoplastic, and elastic materials to be economically ground to very small particle sizes. The cryogenic process actually embrittles a material prior to size reduction and controls heat buildup in the grinding equipment. The result is high product quality and system productivity.
