### CALCULATION OF THE POWER DRAW OF DRY

Calculation of the power draw of dry multicompartment 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.

• ### 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 scats rates, balls discharged from mill, sumps overflowing, cyclones clogging up etc.).
