The starting point for ball mill media and solids charging generally starts 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. Add to this another 10%-15% above the ball charge for total of 23%

ball charge is close to 95 kg (209 lb), occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second.

The energy efficiency of tumbling mills can be examined by directly looking at the motion of rocks and steel balls inside the mill. The make-up of the charge and the lifter bars attached to the inside of the mill shell can be designed particularly to maximize the mass of ore fractured per unit of energy spent on the mill. At the same time, the

During the grinding process, grinding balls are consumed due to abrasive wear and must be replaced progressively (and ideally continuously) to maintain the optimum ''charge'' within the mill. Safe and reliable feeding and delivery of new grinding balls to the mill is a key concern for many mine sites.

The efficiency of a ball mill depends on the number of contact points between the balls • There is a limit of ball diameter below which centrifuging of mill charge occurs; this limit can only be overcome by a change in the manner of ball movement • In sandmills, the grinding charge is driven by an impeller.
