Optimization of Cement Grinding Operation in Ball Mills

Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classifiion of the ground cement into two streams – coarse and fines.

Appliion of Soft Constrained MPC to a Cement Mill Circuit

Abstract In this paper we develop a Model Predictive Controller (MPC) for regulation of a cement mill circuit. The MPC uses soft constraints (soft MPC) to robustly address the large uncertainties present in models that can be identified for cement mill circuits. The uncertainties in the linear predictive model of the cement mill circuit stems from large variations and heterogeneities in the
