Boulders require extra efforts for secondary blasting or hammer breakage and if entered the crushers, they cause downtimes Therefore a more evenly distributed fragmentation with less oversize material can be advantageous Furthermore, a better fragmentation can cause a reduction in energy costs by demanding less amounts of crushing energyImprovement of blastinduced fragmentation and crusher efficiency by means of optimized drilling and blasting in Aitik ACKNOWLEDGMENTS The thesis project presented in this report was conducted in Boliden's Aitik mine; thereby I wish to gratefully thank Boliden Improvement of blastinduced fragmentation and Mobile Crusher Effect effects of fragmentation on the crusher effects of fragmentation on the crusher effects of fragmentation on the crusher Impact coal crusher plant is same as jaw coal crusher More CrusherWikipedia A crusher is a machine designed to reduce effects of fragmentation on the crusher Birch Acres Drilling Blasting Leverage • Drilling and blasting is the first step in the comminution processes • A 10% increase in drilling and blasting cost can be compensated by 946% reduction in excavation and hauling costs or 964% reduction in crushing 1% decrease in excavation/hauling = 21% increase in DB orFragmentation Management for the Downstream Value Overly coarse fragmentation will reduce primary crusher throughput Coarse material will lead to more downtime for clearing crusher bridging and there are fewer geologic and blast induced fractures present in the fragments Since grinding feed is typically less than 3/4 inch, it will only be the smallest macrofractures, and theThe Effects of Blasting on Crushing and Grinding
