Grinding in Ball Mills: Modeling and Process Control

in modeling and control of the grinding process in industrial ball mills. .. In the theory of breakage of solids, the fragmentation process is . The application of forces on the particles in different size classes is shown by solid arrows and the movement of fragments to the same or lower size of classes is indicated by dotted.

Optimal control of a ball mill grinding circuit—I. Grinding circuit .

Mineral grinding circuits can be controlled with a set of proportional—integral (PI) controllers or alternatively by specialized controllers which make use of optimal control theory. The latter control strategy is superior in the sense that feed solid and water addition rates are manipulated in concert to achieve a specified control.
