### ball mill load torque curve

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

Though, there are small differences in the mill speed (N: 0.6 versus 0.7) and ball load (J: 0.5 versus 0.4), in our opinion the main factor is the ball size distribution: a single size ball charge versus a ball charge made up of balls of three different sizes. The void space in the ball charge, the relative movement of different layers of balls
