The capacity of the processing circuit is approximately 500 000 tonnes per annum based on 24 hour operations. From the course ore stock pile ore will be mixed with water and milled to -200 microns before passing to the flotation circuit.
Chat Online· 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.
Chat OnlineHammer 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.
Chat Online· Also the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and even to the flotation circuit. The Millstar Power Optimiser gave the following benefits • Mill feed cuts were prevented resulting in a stable mill loading. • No huge power dips occurred since any sign of the mill
