    • 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, 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.
    • 用于球磨机的驱动系统包括具有滑环转子的马达。 电动机分配了一系列特性,将电动机的转矩与另一个特性变量相关联。 特征族具有至少两个不同的特性,并且包括当存在特征变量的恒定值时在两个特性之间突然切换驱动系统的开关元件。 在用驱动系统操作球磨机的方法中,当第一特征被激活时,球磨机的滚筒被移出静止状态。 在结块在球磨机的滚筒的情况下,滚筒被移动直到结块处于倾斜位置。 开关元件的驱动导致切换到第二特性。
