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.
Abstract. Cryogenic grinding represents an opportunity for expanding recycling capabilities to a broad range of compounds. Many materials that can be reduced to a powder by conventional coarse grinding can be reduced more efficiently by using a super-cold agent such as liquid nitrogen at -320/sup 0/F to embrittle plastic or rubber polymers before grinding.

Grinding spices: How does cryogenic grinding work? Mill cooling uses liquefied cryogenic nitrogen (LIN) or liquid carbon dioxide (LCO2) to significantly reduce the temperatures of the feed material. Cryogenic grinding with in a paddle screw cooler freezes the high fat or oil content in the regrind and makes it brittle.
