#### Analysis of ball mill grinding operation using mill power

Thus, a significantly large amount of electrical energy is consumed in the ball mill grinding operation. It is, therefore, important to establish the optimum values of various mill operating parameters, such as the mill speed, ball load, ball diameter and particle load, from the energy consumption point of view.
