  Analysis of Power Draw in Ball Mills by ...

  Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously .

  The effect of ball size distribution on power draw, charge ...

  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 .

  Models for the prediction of the power drawn by ball, semiautogenous and fully autogenous mills have been developed and cited in the technical literature (Turner, 1982; Austin, 1990; Moys, 1993; Morrell, 1996). However, none of these models considers the feed size distribution as a design variable. In many mine to mill type studies (Simkus and Dance, 1998; Kojovic, 2005; .

   · However, the trend is clear in that as ball mill feedrate increases the power draw falls. As can be seen the average power draw is about ... From this equation it can be seen that the power associated with the rock/ball charge is calculated separately from the slurry, the total power being the sum of both. Some mills have conical endsections and, as they also .

  Ball Mill Design/Power Calculation

  Calculating Power Draw when sizing Ball Mills Grinding. I believe that as circulating load in a ball mill increases beyond a critical point the mill power draw begins to fall so there is an adverse effect on grinding efficiency (apart from the obvious physical problems it causes like high ss rates, balls discharged from mill, sumps overflowing, cyclones clogging up etc.).
