Note that modern wraparound (gearless) mill drives do a software correction to report mill motor output power (which is the same as shell power). Therefore, new gearless mill drives do not require any correction when comparing DCS power measurements to model power draw predictions. Power predictions are only valid below motor rated speed
ball charge., but not less than 18% of the total volume." This states that AG mills are designed at 18% ball safety, mills operating at maximum 12% balls get 6% ball safety, while operations at maximum 18% get 3% ball safety. The original statement was that all mills should be designed at 3% ball safety over their maximum operating load.
