The ball mill liners are located on the inner surface of the ball mill barrel, which protects the barrel from the direct impact and friction of the grinding media and the material. The ball mill liners' material and shape are different base on requirements. When the grinding media contacts different shapes of ball mill liners, the movement state will also change, thus enhancing the crushing ...

Shifting the baffle toward the tail end throws out a coarser overflow; moving it ahead makes the overflow finer and pulls out more sand into the circulating load. In a few mills the classifier overflow weir can be raised or lowered. Raising it makes the overflow finer; dropping the weir makes the overflow coarser.
Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.

Uses of a Ball Mill Liner. The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.
