    Ball Mill Motor Power Draw Sizing and Design Formula

    2021-2-26  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.

    2017-4-1  The mill was attached to a drive shaft, (supported on bearings), and driven by a freely-suspended gearbox and motor. The torque on the drive assembly was measured on-line and the average value was used to calculate power. (The surging of the mill load caused the torque to oscillate.) Mill charge fillings of 30% and 40% were tested.
