High Pressure Grinding Roll Drive. high pressure grinding roll drivequartzcrusher. High Pressure Grinding Roll (HPGR) technology is a reliable workhorse in the . frequency drives (VFD) to provide added process flexibility and reduce roll wear. high pressure grinding .
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 years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. .
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.

The grinding elements are two counterrotating rolls, between which the material is crushed. One roll is designed as a fixed roll and the other one as a floating roll. The required comminution pressure is transmitted via the floating roll. The highpressure interparticle comminution produces compacted cakes of material
