Shifting the Comminution Workload from Secondary to
· The idea is to shift the grinding workload from secondary grind stage to regrinding stage by coarsening the SAG-Ball mill-crusher (SABC) circuit product to 300 µm and introducing the coarse flotation in between the secondary and regrind stages plus introducing the energy efficient grinding technology such as the TowerMill to prepare the feed for rougher flotation with particle size of 95 µm.

Hammer Mill. Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer) which rotates at high speed inside the chamber.
