Ball Mill Power Requirements

Grinding media steel balls on power requirements and energy consumption of a ball mill. with constant mass of the steel balls 20, 30 and 40 kg, the agitator shaft speed was increased from 10 to 100 of the maximum speed, which corresponds to a speed of 50 rpm.

Ball mills are rated by power rather than capacity. today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 mw toromocho, private communications. view chapter purchase book. read full chapter.

The effect of processing parameters on energy. grinding media steel balls on power requirements and energy consumption of a ball mill with constant mass of the steel balls 20 30 and 40 kg the agitator shaft speed was increased from 10 to 100 of the maximum speed which corresponds to a speed of 50 rpm the power consumption w was recorded upon which milling energy consumption
