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, fragmentation better suited to the
conventional crushing and grinding circuits (crusherrodball mill or crusherball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities. circuits The majority of modern grinding circuits include a SAG mill, a ball mill and/or a combination thereof.

The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines fracture of the media
