#### Optimization of Cement Grinding Operation in Ball Mills

Optimization of The Cement Ball Mill OperationOperation and Elements of A Closed Circuit Ball Mill SystemAuditing The OperationResults of OptimizationCement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber. It is lined with classifying-type mill shell liners and provided with finer ball charge. Classifying liners ensure that the ball charge is segregated along the length of the chamber keeping larger grinding media at the beginning o#### Closed-circuit grinding optimization Mineral Processing
