Soft Constrained MPC Applied to an Industrial Cement Mill

Cement mill grinding circuits using ball mills are used for grinding cement clinker into cement powder. They use about 40% of the power consumed in a cement plant. In this paper, we introduce a new Model Predictive Controller (MPC) for cement mill grinding circuits that improves operation and therefore has the potential to decrease the specific energy consumption for production of cement.
