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.

In addition, the grinding tem - perature depends on the work-piece (table) speed. With proper coolant application, the tempera - ture can be kept to a minimum at low table speeds, as is the case with creep-feed grinding. T h e t e m p e r a ture can be kept low at high table speeds, too, as in high-e f ficiency deep grinding. HEDG
