Extended grinding curves are essential to the comparison .

The grinding curve is the product size as a function of feedrate, for a fixed feed size. It is proposed that for each new milling condition, in this case a change in the percentage of ball scats in a mill, the peak in the grinding curve must be sought, and that must be used as the comparative test condition.
