In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement.

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.
