Empty heights of both the chambers measured to calculate the ball charge, filling and estimate the power consumption at mill shaft. Based on the empty height measurements, charging of grinding media in Chambers I amp II calculated as equivalent to degree of filling of 22 amp 21 respectively. The estimated
May 01, 2017 Consequentially, DEM is an accurate numerical calculation method that can predict the power consumption of ball mills more accurately than other methods could. The torque and power of a ball mill usually increase with an increase in mill speed when no lifter exists in the mill N l 0 or H L 0 mm. Usually, the slope is extremely small.

The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases Concha et al. 1992 Katubilwa and Moys, 2009 Erdem and Ergun, 2009.

Aug 01, 2001 The specific power consumption for these two ball shapes is shown in Fig. 16. For N75 there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the non-circular balls falls off rapidly.
