22 May, 2019. The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically ...

A ball mill is a type of grinding machine that uses steel or ceramic balls to grind materials into a fine powder. It works on the principle of impact and attrition. Impact occurs when the balls are lifted by the rotating mill and then drop onto the material to be ground. The force of the impact breaks the material into smaller pieces.

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
