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.

re Cement Mill Grinding Media. These are just the basics if you want to accurately do it you have to fill it up to 80% BC and then do a longitudinal sieving and then correct the BC based on the results. The biggest ball determination is explained and it is based on material hardness and biggest size. Let me know if you need more info.

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". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
