Analysis of Power Draw in Ball Mills by the Discrete ...

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

CALCULATION OF THE POWER DRAW OF DRY

Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

MODELLING THE INFLUENCE ON POWER DRAW OF THE

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 12.5 MW and occurs at a feedrate (new feed plus recy cle) of about 6000 t/hr. Over a wide range of feedrates about the mean value of 6000 tph the power draw varies by only +/- 5%. Of note
