SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and ...

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.
