    In this study, the effect of two different crushing mechanism i.e., JawCone (JC) and JawJaw (JJ) on coarse aggregate morphology is evaluated. 2. Materials and methodology. Granitic aggregate crushed by two different two stage crushing sequence i.e., (i) primary crusher being jaw crusher followed by a secondary cone crusher (JC) ( Fig. 1

  • The Effects of Blasting on Crushing and Grinding

    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. In addition,

  • Mechanism of Crushing of Rocks under Dynamic Loading

    In the mining and quarrying operation, rock crushing process consumes a large amount of energy. Therefore, it is necessary to generate a better understanding of the fragmentation process. Although a number of crushing tests have been reported, most of these tests are based on single particle crushing tests.
