Parameters for the simulation are taken from the literature. Simulation results suggest that a singlecompartment mill produces the desired cement size, but it requires premilled fresh feed. Depending on the ball sizes used, a two compartment mill produces cement sizes similar to those produced by a threecompartment mill.
