  • (HPGR) high pressure grinding rolls/rollers for cement

    The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed s density to 80 of its solid
