Grinding in Ball Mills: Modeling and Process Control

From a control point of view, a ball mill grinding circuit represents an interconnected multivariable system with strong interactions among process variables. A typical structure of a closed-loop circuit for wet grinding consists of a ball mill, sump and classifier [10, 13, 33, 39] and it is schematically shown in. Fig. 4. Fig. 4.
