Get MoreMathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated

Get MoreThus the specific comminution energy can be. determined by 0.0254 Wh/rev (difference between 0.1331 and 0.1077) or 91.44 Ws/rev. This is equivalent to a power draw of 106. 76 W for the mill with

Get MoreAbstract 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 simulated with a
