HPGR High Pressure Grinding Rolls Weir
Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce 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 volume, exceeding its compressive strength with equal pressure 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 sizeHigh pressure grinding rolls (HPGR) Outotec13/07/2016 HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent yearsHPGR High Pressure Grinding Rolls
