    Most particularly, energy consumption in grinding islarge. The reason is that the change from feed size to product size, achieved in grinding, is typically much greater than in crushing. There is significant evidence that blasting does affect crushing and grinding results, and that large savings in cost can accrue (Eloranta, 1995; Paley and Kojovic, 2001).
