Aug 10, 2020 Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

From the way the ball mill works. In the operation environment, the ball mill is divided into two types wet ball mill and dry ball mill. Dry Ball millwork has a strong corrosion, so as the same wear-resistant grinding media ball, the wear-resistant grinding media ball in the wet grinding efficiency is faster.
