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.

The critical speed of a ball mill can affect the performance and product quality of the mill. If the speed is too slow, the grinding balls will not be lifted and will not effectively grind the material. On the other hand, if the speed is too fast, the grinding balls will be thrown against the outer wall of the mill, resulting in ineffective ...
