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
mineral bearing rock, either chemically or physically. prior to this the ore must be crushed to a size suitable for grinding. grinding is then done to produce fine particles which can be processed either chemically or physically. although this paper concentrates on energy consumed in comminution the
primary crushers are suitable for the primary crushing or grinding of clay and minerals coming directly from quarries and for reducing its original irregular size to uniform sizes below so that the material may be properly batched and stored.
selective grinding refers to a kind of grinding phenomenon in which the ore fragmentation degrees is different in the grinding process due to the difference in hardness between minerals. the main purpose of the crushing and grinding operation is not to reduce the ore particle size, but to dissociate the useful minerals from the gangue minerals.
