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.
High capacity High Pressure Grinding Rolls for all your use cases. During its relatively short history in minerals processing, HPGR technology has undergone significant development in machine roll wear surfaces and control philosophy. Initially introduced as a cement industry product in the mid 1980s, HPGRs soon gained a (minerals processing ...
