Efficiency Calculation Of Rock Grinding Mill India

The Effects of Blasting on Crushing and Grinding

Large hard rock mines expend enormous amounts of energy with associated costs A substantial portion of this energy is expended in crushing and grinding Most particularly energy consumption in grinding is large The reason is that the change from feed size to product size achieved in grinding is typically much greater than in crushing
