In other words, the capacity should be proportional to the mill speed raised to power m, the numerical value of the exponent being 1 m 1.5, depending on the

Get PriceAbstract 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
