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. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
The grinding balls and the material in the grinding jar are acted upon by the centrifugal forces due to the rotation of the grinding jar about its own axis and due to the rotating planetary disk. The grinding jar and the planetary disk rotate in opposite directions, so that the centrifugal forces alternately act in the same and opposite directions.

Whenever two grinding balls collide, a small amount of powder is trapped in between them. Typically, around 1000 particles with an aggregate weight of about 0.2 mg are trapped during each collision (White, 1979). During this process, the powder morphology could be modified. For the soft powders like
The galvanic reaction tended to protect the chrome balls at the expense of the forged balls. There weren't enough chrome balls in the charge to significantly affect the forged ball wear rate. Once we converted a mill to chrome balls we found that the consumption rate was significantly higher than the marked ball tests predicted.
