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 motor input power draw less the no-load power. 4.
