A Review on Cryogenic Grinding Inpressco

2017-6-2  Cryogenic Grinding is the process of cooling or chilling materials and reducing it to small sized particles. Since almost all material embrittle when exposed to cold temperature. Cryogenic size reduction utilizes the cold energy available from defined cryogenic fluids to cool, embrittle and inert materials prior to and or during the grinding process. This helps to overcome the difficulties of all the elastic materials observed in ambient temperature grinding
