A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages: •

Common problems of ball mills and solutions to failures. 1. When the ball mill is running, there is a regular percussive sound, and the sound is loud. When the ball mill rotates, the liner hits the grinding cylinder of the ball mill. Judge the position of the liner of the ball mill according to the sound, find out the loose bolts and tighten ...

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.
