The S f was identified as the most effective parameter on grinding efficiency. The cut-size plunged dramatically from 130 to 90 μm by reduction of S f from 54 to 48 . Finally it was concluded that the capacity of grinding circuit could be practically increased to 300 tph if all relevant parameters fell into the optimised ranges.
