Grinding Balls and Other Grinding Media: Key consumables
Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).

Ball Mill Grinding Media Options | Ceramic Balls for Ball Mill
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.
