The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Multi-variable control Grinding circuit 1. Introduction Ball mill grinding circuit is one of the most important mineral processing units in concentrator plants. The product particle size of the grinding circuit has a great influence on the recovery rate of the valuable minerals and the final tailing discharge.

Abstract Ball mill grinding circuits are essentially multivariable systems with high interaction among process variables. Traditionally grinding circuits are controlled by detuned multi-loop PI controllers that minimize the effect of interaction among the control loops. Detuned controllers generally become sluggish and a close control of the circuit is not possible.

Grinding mill circuits are the most energy and cost intensive unit processes in the mineral processing industry and therefore the study of the control systems for grinding circuits remains important (Ramasamy et al., 2005, Wills and Napier-Munn, 2006).Grinding circuit control objectives range from maintaining system stability to achieving maximum economic …
