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% ...

Impact of ball size distribution, compartment configuration, …
Having the same length, a two-compartment mill obviates the need for pre-milling and performs similarly or better than a three-compartment mill, depending on the ball sizes used. For a given set of ball sizes, a distribution with uniform mass of balls, as opposed to that with a uniform number of balls, achieves 8% increase in cement specific ...

A single-compartment mill entails a pre-milled feed for proper operation, whereas a two-compartment mill yields a finer cement product than a three-compartment mill. Uniform mass distribution of balls led to slightly finer product than uniform surface area or number distributions, while the impact of a classifying liner was negligibly small. ...
