Ceramic grinding media are also suited for use in processes where mixing and dispersing effects play an important role. In the majority of these grinding processes, steatite and alumina are the most common ceramic materials used for grinding balls and linings. CeramTec generally manufactures its grinding balls and linings with steatite.
2) For continuous type mill : Grinding media should fill 35% of mill’s useful volume. To Calculate media charge for cylindrical mill, the formulae are given as below : 1. For batch type ball mill : M = 0.000929 x D 2 x L. Where M = Weight of the grinding media charge in Kgs. D = Mill internal dia in cms after lining.
