### Predictive Controller Design for a Cement Ball Mill

· The process considered in this study is an indigenous ball mill grinding circuit located nearChennai. They procure clinkers from dierent places across the country. Hence the characteristics ofthe clinkers from dierent mills vary to a large extent. An important characteristic that is considered inthis work is the grindablity factor. This is the measure of clinker hardness. The nominal grindabilityfactor for the clinker is 33 which is a dimensionless quantity. The grindability factor of the clinkeris analysed in the laboratory. Harder clinkers have a lower grindability factor and vice versa. Since theclinkers are procured from dierent mill across the country the grindability varies to a larger extent.For modelling the ball mill grinding process the suitable control strategy is to be established forthis indigenous grinding unit to ensure product quality and productivity under optimised energyconsumption even in the presence of larger variations in the grindability
