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 feeds density to 80% of its solid
