Grinding In Ball Mill

Optimization of Cement Grinding Operation in

Cement 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
