    They extend to almost the full length of the shell and occupy about 35% of the shell volume. In such mills, attrition forces predominate but impacts also play a part in size reduction. They are classed as intermediate grinders and are more useful than ball mills for milling sticky materials. 43.6 Selection Criteria for Size-reduction Equipment

    The ball mill consists of hollow cylindrical rotating shell made of steel lined with porcelain or high carbon steel plate. Upto 50 % of its volume, the shell is filled with balls made of steel or pebbles. The balls are of constant weight and varying size which depend on the amount of feed. The size reduction happens due to
