Model Predictive Control for SAG Milling in Minerals ...

Mill rotational speed may be variable, in which case increasing speed increases grinding capacity, since this increases the rise and subsequent fall of ore and media – provided the mill is not run up to critical speed. Mill speed variation has a large gain effect in terms of control and is important to compensate for variations in ore hardness.
