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.

2. Feed rate to the circuit (dry tonnes/h) 3. Power draw of the comminution equipment (kW) •In the case of mills, the power draw should be repre-sented in terms of power at pinion for gear and pin-ion drives and at shell for gearless drives. For crushers, this should be the net power draw, that is, the gross
