MODELLING OF CEMENT GRINDING CIRCUITS FOR PREDICTIVE CONTROL
Abstract. A first principles model of a cement grinding circuit is developed for the purpose of multi-variable model predictive control (MPC). The model is based on a series of mixed flow reactors with an ideal screen to model flow between the two chambers in the ball mill. The separator is modelled by efficiency curves.
