The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners).

A practical case of ball mill foundation is examined herein. The diameter of mill is 8.0 m with length of 13.1 m, operating at 12 rpm. The height of mill shaft is 18.1 m above ground.

AC 1 HP single-phase AC motor has an input voltage of 230V, the input current of 3.8 Amps and working at 2500 rpm, 0.8 pf, 100% load. Calculate the torque of the motor. Apply our formula 1, T (N.m) = 230 x 3.8 x 0.8 x 100% / (2 x 3.14 x 2500 / 60) = 2.66 N.m. The torque produced by the motor is 2.66 Nm. Hence 1 HP motor can produce 2.66 N.m
