sag power draw prediction

Grinding mills: how to accurately predict their power draw- sag power draw prediction ,model treated AG,SAG and ball mills as a single class of devices whose power draw could be predicted with the same equations Through a detailed investigation of the charge dynamics, coupled with .What is "Sag,Aiken AmpsWhat is "Sag,General , and the amount of voltage drop goes up linearly with increases in current draw A typical power transformer B+ winding might have a resistance of 50 ohms - 300 ohms, depending upon the current rating and regulation of the transformer For example, if the current draw in a push-pull class AB output stage at ,.
