Grinding Compartment. A cement ball mill is generally divided into two or three grinding compartments. The larger the length-diameter ratio of the ball mill is, the more compartments there are. For dry ball mills used in the closed-circuit grinding system, when divided into two compartments, the first compartment length accounts for 30% – 40% ...
