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.

Some experimentation is inevitable in determining the exact amounts of material charge to use. While the media charge should always be 50%, material charge will vary from 25% to 40% or more in some cases such as when grinding homemade airfloat charcoal. The best way to tell if your mill is properly charge is to listen to it after
