CiteSeerX — MODELLING OF CEMENT GRINDING .

Abstract. Abstract: A rst principles model of a cement grinding circuit is developed for the purpose of -variable model predictive control (MPC). The model is based on a series of mixed ow reactors with an ideal screen to model ow between the two chambers in the ball mill. The separator is modelled by eciency curves.
