Ball Mill Power Calculation Example 1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80 passing ? inch 6350 microns. The required product size distribution is to be 80 passing 100 mesh 149 microns.
The model result is horsepower per foot of mill effective grinding length, so multiply the result by the mill EGL to get pinion power draw. Effective grinding length EGL The effective grinding length of a ball mill is the belly length of the mill inside the mill liners from the inside of the head end liner to the inside of the discharge end liner or grate.
