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.
