Abstract

Die Erfindung betrifft eine Vorrichtung zum Zerkleinern von Aufgabegut mit einem innerhalb eines Gehäuses um eine Achse rotierenden Rotor (9), der über seinen Umfang mit Rotorwerkzeugen (12) ausgerüstet ist und der über einen von achsparallelen Längswänden (26) und dazu senkrecht verlaufenden Querwänden gebildeten Zuführschacht (25) beschickbar ist. Dabei weist zumindest eine Längswand (26) im umfangsnahen Bereich des Rotors (9) eine Öffnung (27) auf, die mittels einer angetriebenen Klappe (28) verschließbar und freigebbar ist. Zur Abwendung der Gefahr, dass beim Zerkleinerungsvorgang durch Fremdkörpereinwirkung die Vorrichtung Schaden nimmt, wird erfindungsgemäß vorgeschlagen, dass der Antrieb für die Klappe (28) mindestens einen Aktor und einen vorgespannten Energiespeicher umfasst und der mindestens eine Aktor unmittelbar mit Antriebsenergie aus dem vorgespannten Energiespeicher beaufschlagbar ist.

The invention relates to a device for comminuting feed material with a rotor (9) which rotates about an axis within a housing and which is equipped with rotor tools (12) over its circumference and which is formed by a longitudinal wall (26) parallel to the axis and transverse walls perpendicular thereto Zuführschacht (25) is loadable. In this case, at least one longitudinal wall (26) in the region of the rotor (9) close to the circumference has an opening (27) which can be closed and released by means of a driven flap (28). In order to avert the risk that the device will be damaged during the comminution process due to the action of foreign bodies, the drive for the flap (28) comprises at least one actuator and a prestressed energy store and the at least one actuator can be acted upon directly by drive energy from the prestressed energy store ,
