A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a

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

This is how grinding in a ball mill takes place [2]. The relation between grinding productivity and loading of a ball mill by the material is proportional. The more material is fed into the mill the higher grinding productivity. But at some point there is too much material in the mill and the material is not grinded any more, the grinding productivity decreases abruptly down to zero and the
