Fig. 1 shows the process flow of a closedcircuit, twocompartment cement ball mill. The closedcircuit operation helped to reduce overmilling of particles [10], resulting in lower specific power consumption [11] in comparison with opencircuit operation, where the ball mill is operated without the external air classifier.

Our results suggest that integrating an air classifier into an opencircuit ball mill can increase the production rate by 15% or increase the cementspecific surface area by 13%. A singlecompartment mill entails a premilled feed for proper operation, whereas a twocompartment mill yields a finer cement product than a threecompartment mill.
