For instance, running the AKG SE300B Blue Line electronics at the voltages below shows the difference in phantom power consumed. 15 V from the MP-2 x 0.002 A 0.030 W 30 mW

View All2018-8-8maximum power draw well below the installed power. Typically, at startup post SAG mill reline, the maximum operable speed ranges are reduced to minimise direct shell impacts due to the steeper face angle of the lifters. This operational approach severely limits available power draw by the mill to maintain higher throughputs for competent ores
View AllThe power draw for the simulated ball mill 5700 kW is close to its rated motor power 6000 kW, however, greater than the power draw for the actual mill 5268 kW. The increase in power draw is due to an increase in ball volume from 24 v v actual to 27 v v simulated. This increase in ball volume results in an increase in
