3. CEMENT INTERNATIONAL 4 2/2013 4 VOL. 11 65 1 Introduction There is no question that vertical roller mills like the Loesche Mill offer significant advantages over ball mills in terms of their energy efficiency. As noted in a current publication (1) the specific power consumption of a ball mill is higher than that of a vertical roller mill (VRM) carrying out the same oper ations by a factor ...

A focus on ball size optimisation in a cement mill. Several investigators (Austin et al, 1975; 1984; Zhang, 1988; 1992; Benzer, 2000; 2001; Slanewski, 1985; Viswanathan, 1988; Ozer, 2006) have studied mathematical modelling of cement mills on the basis of population balance models (PBM) for simulation and optimisation of cement grinding circuits.
