  • Downstream effects of cave fragmentation srk

    Since the 1990s, mine to mill studies have evaluated the impact of blast fragmentation on downstream plant throughput. This was because crushing and grinding circuits (in particular, SAG mills) are sensitive to feed size and the amount of fines generated from blasting. Significant gains in grinding circuit efficiency could be achieved by controlling and optimising blast fragmentation.
