These models can be used to simulate cement grinding circuits and to assist their optimisation. The "work horse" of the cement grinding plant is the two-compartment ball mill, commonly called the tube mill. Significant advances in model development were achieved in recent years (Benzer et al, 2001, 2003) through research on industrial scale.
