Ball consumption would, therefore, be 1.22÷5.693 = 0.214 lbs. balls per KWH input to the mill. For the Pinto Valley concentrator ball consumption should, therefore, be 0.214 x 8.39 = 1.80 pounds per ton. Ballmill liner consumption was again estimated from Copper Cities experience as 0.015 pound per KWH of primary grinding energy. To-date only the discharge and intake throat liners have been replaced.
