Ball grinding mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. In order to achieve a reasonable efficiency with ball mills, they must be operated in a closed circuit system, with oversize material continuously being recirculated back into the mill to be reduced.

PDF - In this paper, we develop a novel Model Predictive Controller (MPC) based on soft output constraints for regulation of a cement mill circuit. The MPC is first tested using cement mill simulation software and then on a real plant. The model for the MPC is obtained from step response experiments in the real plant. Based on the experimental step responses an
