Apr 4, 2017 . If the rock needs 10 kwh/t which is based on a CL of 250% and the plant requires 150 tph, then the mill must deliver 1,500 kw at steady state. That will not be the size of the attached motor which must be capable of starting the mill, up to twice as much nameplate power. Power draw is basically related to.

May 6, 2004 . losses and other energy consumed, k, is 1.26. From Equation 2: gross power. (power input to the motor): 1365.04kW. Graphically the accuracy of this new approach to calculate power draw of dry ball mills used in cement grinding is illustrated in comparisons of the observed and predicted power draws in.
