SHEDDING LIGHT ON SECONDARY CRUSHING B. Putland,
Secondary crushing of the SAG mill feed, when implemented correctly, has been shown to significantly reduce SAG mill and total circuit specific energy. Very fine feed, good process control and or the presence of some coarse rock in the feed (partial secondary crushing) has been required to make a successful project. The reason secondary ...

Selection of Comminution Circuits for Improved Efficiency
These costs represent 30% of costs for the 1 Mt/a plant and over 50% of costs for the 20 Mt/a plant. Thus, the “efficiency” of a modest plant is improved by simplifying the comminution circuit and reducing labour requirements. Improving the grinding efficiency of the comminution circuit by 10% will improve plant operating costs by less than 3%.
