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

the mill is used primarily to lift the load medium and charge Additional power is required to keep the mill rotating 813 Power drawn by ball semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 83 Ad this can be used to establish the essential features of a model for mill
