Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).

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.
