    Empirical correlations developed to calculate the mill power draw from design and operating parameters (Guerrero and Arbiter, 1960; Bond, 1961; Hogg and Fuerstenau, 1972; Morrell, 1992; Hlungwani et al., 2003). All of these models were not able to respond to change in lifter geometry and ball size distribution. The solution to this problem is the use of numerical tools, such as
