Ball Mill Loading - Dry Milling - Paul O. Abbe

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 Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading.

A Power Based Approach for The Selection and Comparison of Ball Mill Liners

Results show the mill ball charge shoulder angle is strongly affected by the liner lifter's face angle and that Morrell's Model C could be improved by including a correction parameter that reflects the power draw of a mill along the service life of its liner. The correction parameter is to reflect the effect of wear on the shoulder angle.

Ball Mill Charge - Metallurgist & Mineral Processing Engineer

The ball charge is determined by the operator targeting the balance between grind and throughput, the higher the ball charge the more aggressive the milling becomes. With softer oxide ores lower ball charges are usual however the harder sulphides does need more media energies to meet the P80 target and an acceptable throughput.
