High pressure grinding rolls are steadily becoming ubiquitous in the copper mining industry, replacing the SAG mill grinding stage. The HPGR exposes feed material to very high pressure for a short amount of time. The compression typically causes the rock to crack and cleave along the grain boundaries, weakening the rock structure.
