Electromechanical Dynamic Behaviour and Start-Up
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 begins to cascade and fall which causes the load torque
