Ball Mill Torque Curve. the mill supplier Ball mill torque curve Cascading point is at 60176 independent of speed Figure 2 The torque speed characteristic curve for a recent ball mill is shown in Figure 2 Mill suppliers define the starting torque at an angular displacement of the charge The cascading point of this mill is at angle of 60176 This implies that a
After the speeds of the driving disc and the driven disc are synchronized, the load torque of the motor is equal to the load torque of the ball mill. Although the theoretical friction torque still increases, as shown by the solid line in the Figure 7, the friction torque that the air clutch transmission is equal to the load torque of the ball mill. In addition, with the rotational speed and angle of the barrel increase, the material

12/05/2000#0183;#32;Abstract: The time has come to rethink the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints.
