A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

The use of small grinding media (5 - 12 mm), called Millpebs, in regrind mills proved that fi ner grinding can be achieved at lower energy consumption. In ball mills, energy savings vary from 10 per cent to 40 per cent compared to 25 mm media. A regrind ball mill with a mix of small grinding media

Abstract. The generation of grinding media wear during wet stirred media milling of organic particles was studied in dependence of product formulation parameters. It was shown that targeted product formulation leads to the reduction of ceramic grinding media wear for a certain product quality. Solids concentration and agglomerate size of ...
