 · These rolls draw the feed material into the gap between them where it is ground under high pressure. A hydro- pneumatic system generates the required grinding pressure of up to 250 MPa. The grinding process produces compacted cakes containing a high proportion of fines as well as coarser particles with cracks in them.

High pressure grinding rolls (HPGR) Outotec

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.
