Cryogenic grinding performance of scrap tire rubber by
网页2020年9月1日The key step of cryogenic grinding is to freeze the rubber so that it is in a brittle state. This freezing process consumes a large amount of refrigerant, such as liquid nitrogen, and results in a high cost for rubber powder production. The cost problem has already become a strong factor hindering the development of cryogenic grinding process.
