• Cryogenic grinding: an efficient method for recycling ...

    Cryogenic grinding represents an opportunity for expanding recycling capabilities to a broad range of compounds. By using a super-cold agent such as liquid nitrogen at -320 degF to embrittle plastic rubber polymers before grinding, cryogenic grinding makes possible the size reduction of many materials that cannot be ground by conventional ambient grinding methods.

    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
