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 of the maximum speed, which corresponds to a speed of 50 rpm.

In all cases, the specific energy consumption is defined as the motor power consumed relative to the shell of the mill (a.k.a. power at the pinion output) divided by the fresh feed rate in dry tonnes per hour. The simplest models use a single grindability measurement to estimate the specific energy

Charge behaviour and power consumption in ball mills. Aug 01, 2001 The specific power consumption for these two ball shapes is shown in Fig. 16. For N≤75% there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds.

It is also possible to use the −1″ fraction that shows a positive effect on the SAG mill throughput (the power consumption decreases, but the specific energy decreases more) because the mineral goes faster to the mill discharge, leaving a greater part of the grinding task to the secondary ball mills.

Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.
