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.

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.

A typical SAGHPGRBall mill circuit suggested by Patzelt et al. [6] is shown in Figure, where the pebbles from the SAG mill are crushed in the highpressure grinding rolls. It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced.

2 Small mills in Africa Largerscale mills are in operation in most African countries today. They mainly supply flour to larger cities and towns. These mills use fluted roller mills that operate to a higher technical standard than smallscale mills do. They can remove bran and wheatgerm, producing refined white flour mainly for bread making.
