Sep 01, 2016 The effect on overflow ball mill power draw of the minor changes attributable to the increased feed rate may be different to that on an AG/SAG mill. For an overflow ball mill, the increased slurry pool volume resulting from the increased mill feed rate will not lead to an increase in ball mill power draw rather more often the opposite. Effective mill power draw Ball mill specific grinding rate Ball mill grinding efficiency The circuit output is defined as the production rate of fines by the circuit. It is calculated from three values 1. The dry ore feed rate to the circuit (t/h). 2. The % fines in the circuit feed. 3. The % fines in the circuit product.
