ball charge., but not less than 18% of the total volume." This states that AG mills are designed at 18% ball safety, mills operating at maximum 12% balls get 6% ball safety, while operations at maximum 18% get 3% ball safety. The original statement was that all mills should be designed at 3% ball safety over their maximum operating load.
