The Effects of Blasting on Crushing and Grinding,

A third factor of effectiveness in crushing and grinding is mineral liberation. Greater liberation means improved downstream recovery. A currently unanswered question is whether blasting that creates more microfractures around or through mineral grains will improve liberation and recovery. Energy Consumption in Crushing and GrindingTHE EFFICIENCY OF BLASTING VERSES CRUSHING AND GRINDING,Crushing is done in three stages, reducing to 80% passing 2 cm (3/4 inch). Rod and ball mills take the ore down to an 80% passing size of 60 microns (270 mesh). METHODOLOGY The Bond equation is a useful tool to compare predicted and actual values of energy requirements for each step in taconite comminution. Crushing and grinding energy are measured[PDF] The Effects of Blasting on Crushing and Grinding,,28-11-2020· Blasting has an important impact on mining and milling well beyond the necessary ability to dig and load the ore efficiently. There is an increasing body of blasting research indicating significant impacts in crushing and grinding. These include increased production through higher output and fewer delays for bridging and jamming by oversize.
