Benchtop ball mill Laboratory scale ball mill Highenergy ball milling. A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

The four most common coal pulverizers types are: BallTube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills.

The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.
