    There is evidence that Bond work index is significantly reduced by heavier blasting (Nielsen and Kristiansen, 1996). There is, however, recent research that suggests that while significant softening is seen at the crushing stage there is little change at the grinding level (Katsabanis et al, 2003, 2 papers).

    2010-11-4 · The survey sample sizing data were then used for mass balancing and calibration of crushing and grinding circuit steady-state models. Blast design changes were modelled and the predicted run-of-mine fragmentation ‘fed’ to the grinding circuit model during a number of simulations to achieve different increases in mill throughput. The blast patterns were designed to increase the amount of ultra fines generated during blasting that cannot be created through conventional crushing.
