  • Ball Mills

    A mill filled with balls, working idle, consumes approximately as much energy as at fullscale 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: • Universality and high capacity. • Permanence of a prescribed milling fineness by certain capacity over long periods ...
