  • Minetomill Optimisation Effect Of Feed Size On Mill

    Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding. One of the most valuable aspects of blasting is the generation of very fine particles e.g., smaller than 12mm that will
