<1000 cps for alumina media <2000 cps for steel media The starting point for ball mill media and liquid charging is generally as follows: 50% media charge Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space

A SAG mill of diameter 9.0 m and width 6.0 m was charged to 40% of the mill volume with ore of SG 3.2 when the porosity was 38%. With grinding time the ball load changed from 10% to 5% and the bed porosity to 12%. Estimate the change in power due to the change in mill conditions. The mill was run continuously at 70% of the critical speed.
