The ball charge tendency in the 1 st compartment is to use the coarser of the gradings available. When producing high Blaine Cement it is the objective to use less tonnage. Achieve nearer 8-9 kWh/t at the target mill output instead to go for a more fine ball charge. 3.2 Transition zone (2 nd compartment) CM and RM.
When the assay formulas are used and screen analyses constitute the assay it is wise to calculate the per cent, circulating load for more than one size and use the average figure; in taking the average, reject all computed circulating loads that are obviously out of line, probably on account of errors in sampling or sieve analysis.
