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.

Abstract A dynamic non-linear model was fitted to the grind curve data of an industrial semi-autogenous grinding (SAG) mill by means of a step-wise procedure. Grind curves give the steady-state values of the performance variables throughput, power draw, and grind in terms of the mill filling and critical mill speed. The grind curves indicate the operable region of the grinding mill.
