ABSTRACT:
At a fiberizer of a waste paper processing installation the rotational moment or torque is determined, for instance by measuring the drive output of a drive motor. In the presence of an increase of the rotational resistance of the rotor of the fiberizer there is brought about an intensification of the separation of rejects through a reject line and vice versa. For this purpose there are arranged in either the reject line or the good stock line, or at the same time in both such lines, throttle elements which are activated by a regulator. The regulator is controlled by a measuring signal of a measuring device which determines the electrical drive output of the rotor.
