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.
