Apr 01, 1999 The ball load, at which the mill draws maximum power, is about 53%. The simulation results of 0.762-m mill running at 60% critical speed are plotted in Fig. 4. The relevant operating and simulation parameters are listed in Table 3. The calculated power draft is maximum at about 50% ball

Oct 14, 2015 The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or Azzaroni (1984) or by using special batch-grinding tests interpreted in the content of population balance models (Lo and Herbst 1986)

Jul 18, 2013 Abstract. Ball mills, characteristic of the mineral processing industry, are used to reduce ore from one size distribution to another. Wear is associated with comminution mechanisms found in the ball charge which in turn affects grinding performance. In this work, ball mill wear, as a function of mill operating variables, is determined using a
Apr 01, 1997 Modelling the forces acting on the mill liners becomes the next step to predicting mill wear and its effect on grinding. During mill operation, the ball charge exerts a force field composed of gravitational and centrifugal components on the mill liner (Fig. 7) [23, 251. Fig. 7. Ball charge forces acting on mill liner.
