Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the ...

Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, with correspondingly a higher capital cost. However, the increase in capital cost is justified economically by a reduction in operating cost attributed to the elimination of steel grinding media.

A third ball mill takes a split of feed from each module to assist maintaining a target product size. Both modules are fed from the same primary crushing circuit via a Coarse Ore Stockpile (COS) which provides surge capacity. The grinding circuit is designed to produce a product size suitable for the downstream froth flotation process.

The endemic issue of ball mill overload in SABC circuits

The endemic issue of ball mill overload in SABC circuits

As circuit capacities are expanded by ‘releasing’the SAG mill bottleneck, the work is progressively passed on to the downstream ball mills. This tends to be absorbed as a coarser grind and usually the consequential reduction in recovery, until it is dealt with through addition of extra milling capacity.
