    摘要： A drive system for a ball mill includes a motor with a slip-ring rotor. The motor is assigned a family of characteristics relating the torque of the motor to a further characteristic variable. The family of characteristics has at least two different characteristics, and it includes a switching element that switches over the drive system abruptly between the two characteristics when there is a constant value of the characteristic variable. In a method for operating a ball mill with a drive system, a drum of the ball mill is moved out of a state of rest when the first characteristic is activated. In the event of caking in the drum of the ball mill, it the drum is moved until the caking is in an inclined position. Actuation of the switching element brings about switching over to the second characteristic.
