Get PriceMill Charge

The speed of rotation of the mill influences the power draw through two effects: the value of N and the shift in the center of gravity with speed. The center of gravity first starts to shift away from the center of the mill (to the right in Figure 7.4(a) ) as the speed of rotation increases, causing the torque exerted by the charge to increase and draw more power (see Section 7.2.2 ).
