This mill is normally operated in open circuit with the classifier and ball mill Usually there is a power saving with this grinding arrangement and often a substantial saving in the cost of the entire mill can be effected by reducing to a minimum some of the requirements in the crushing plant due to this method

calculations define the efficiency of a fine stagecrush ball mill circuit as 10 to 12 depending on ball mill feed size and some SABC SAGball millpebble crusher circuits operating with an efficiency of 1314 or higher on coarse feed

The effect of a ball charge equal to 2 of the autogenous mill volume was a coarser grind in open circuit This transfers some of the grinding from the lower operating cost autogenous mills to the higher cost ball mills which is usually not economical

Thus in a given grinding circuit for a certain feed rate a pebble mill would be much larger than a ball mill with correspondingly a higher capital cost However the increase in capital cost is justified economically by a reduction in operating cost attributed to the elimination of steel grinding media

Operating Costs The operating cost estimate OPEX was developed as a bottomup estimate over a 10 year mine life to obtain average operating costs The methodology adopted allows for an accuracy of 10 to 15 The total operational expenditure for the project is estimated to be US642 per ounce produced or US2336 per treated tonne
