friction between the ball and the mill, the ball and the coal contributes to the grinding capacity. Enlarging the mill's loading capacity can increase the percentage of the kinetic energy in balls' total energy. However, when the loading capacity is excessive, it also can limit the ball's motion and reduce the ball's kinetic energy.
