Ball Mill SBCCO-CEMENT - SBCCO-CEMENT. A ball grinding mill consists of a hollow cylindrical shell that is partially filled with balls. The grinding media is the steel balls that can reduce the size of materials to a fine powder. Grinding can be carried out either wet or dry for various ores and other materials.

Ball mills are available from 0.1 to 5000 gal wet or dry capacity. The ball mill is extremely efficient for secondary grinding after crushing. The ball mill can grind all kinds of ores and other hard materials. Additionally, both primary and secondary grinding with a ball mill can be applied in a variety of industries.

re Cement Mill Grinding Media H there, 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 selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The second objective is to provide the correct ball size distribution to grind the finer particles in the composite ball mill feed.
