The increase in mill diameter evidently resulted in an increase in mill holdup, but without an associated increase in mill power. Indeed, the increase in mill diameter resulted in even a reduction in mill power from 846 to 602 W. The net result was a dramatic reduction in specific breakage rates with increase in mill diameter, shown in Fig. 19 ...
