Ball Mill Charge Control. Direct control of ball mill inventory has been the goal of a number of investigators over many years. To put some numbers on these concepts consider a 250 ton mill with 3 nominal 10 ton inventory that should be controlled to one part in forty that is a 2.5% band or ¼ ton. This will require a weight resolution of ±0.05%.
