Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.
The grinding materials are actually small balls which crush and grind the material that is inside the ball mill. Usually, stainless steel or ceramic balls are used as grinding materials.
The ball mill is used for the grinding of a wide range of material, including coal, pigments and felspar for pottery, and it copes with feed up to about 50mm size. In its simplest form, the ball mill consists of a rotating hollow cylinder, partially filled with balls, with its axis either horizontal or at small angle to the horizontal.
