Cement mill - Wikipedia

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

Control of a Closed Circuit Cement Mill

Abstract The design of a control system for a closed circuit mill is developed. The control strategy is to estimate the point of instability for the unit and to control the mill at a constant value away from this point. Several models of the mill are presented. The first is a high order model which is used to develop a simplified continuous model.
