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.

A ball mill is a drumgrinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.

Surface area is directly affected by the balls' sizes. Capacity of ball mill increases as ball size decreases, and also the balltoball contact increases as the balls decreases in size because more balls can accommodate the mill. Using different ball sizes can improve the milling efficiency. Balls that are responsible for refining the powders ...
