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.

Abstract. This paper describes a method for assessing the downstream milling energy requirements for high pressure grinding rolls (HPGR) products based on a Bond mill test procedure. Multiple tradeoff studies have reported the performance of HPGR versus SAG milling with energy savings of between 11 and 32 per cent.

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.
