Ball Mills An Overview Sciencedirect Topics

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 i.e. during grinding of material. Therefore it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages
