  • High pressure grinding rolls (HPGR) Fruitful

    High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.Why your HPGR needs to skew The Weir Group,Oct 02, 2019· With their excellent throughput capacity, low maintenance requirements and energy efficiency, High Pressure Grinding Rolls (HPGRs) are fast becoming a go-to for greenfield projects looking to maintain their margins despite commodity price pressures and declining ore grades. “In service since the mid-eighties and used primarily in cement production, HPGRs are increasingly being
