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.

Closed with a flipflow screen, the HPGR reduces the feed size from −12 to −1 mm, and the tower mill circuit produces a flotation feed with a fineness of 85 % passing mm. This comminution circuit has HPGR for partial coarse grinding and uses tower mill to replace the energyinefficient ball mill for primary grinding.

Instead of conventional AG/SAG and ball mills, processes only with highpressure grinding rolls (HPGR) and vertical mills (Fig. 5) or other combinations of mill types are employed in practice. Besides a pure grinding feed, a crucial aspect is the optimum energy utilization in beneficiation for the respective types of ore and applications.
