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.

Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry.

According to Cleary (2001), grinding in ball mills is still far from being effective due to high consumption of electrical energy and steel (grinding media). Currently, the cost of steel balls amounts to 45% of the total cost of grinding materials in ball mills (Lameck, 2005). The remaining costs include energy consumption and ball mill lining.
