Operation and Elements of a Closed Circuit Ball Mill System. 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.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".

As for the influence of hardness, generally speaking, as the hardness increases, as long as it does not break, the single consumption of the grinding media ball decreases, and the deformation of the ball body is reduced, the absorption deformation energy of the ball body is small in the process of crushing, and the energy can be used more for crushing mineral grains The productivity of the mill can be increased.
