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.

Ball Charge. Ball mills for cement grinding usually operate with a filling degree between 25 and 35 %. The filling degree is defined as the volume of the grinding media (balls) as a percentage of the total mill volume. Since mill speed, liner shape and mill diameter are usually unchangeable parameters, the only adjustment in a mill can be made ...
