Abstract

Die Erfindung betrifft eine gasdurchströmte Zerkleinerungsmaschine mit einem rotierenden Schlagradsystem. Zur Zerkleinerung des Aufgabeguts wird dieses axial in den Zentralbereich des Schlägerrades gefördert, dort umgelenkt und in radialer Richtung den kranzförmig um das Schlägerrad angeordneten Zerkleinerungswerkzeugen zugeführt. Um eine über die Länge der Zerkleinerungswerkzeuge gleichmäßige Abnutzung zu erzielen, sind mindestens zwei in der Tiefe des Zerkleinerungsraumes axial gestaffelte Prallflächen angeordnet, wobei die in axialer Förderrichtung nachfolgende Prallfläche über die axiale Projektion der vorhergehenden Prallfläche übersteht. Zusätzlich offenbart die Erfindung ein Verfahren zur Optimierung der Größe und Position der Prallflächen einer erfindungsgemäßen Zerkleinerungsmaschine.

The invention relates to a gas-flow crushing machine with a rotating impact wheel system. To comminute the feed material, it is conveyed axially into the central area of the beater wheel, deflected there and fed in the radial direction to the comminution tools arranged in a ring around the beater wheel. In order to achieve uniform wear over the length of the comminution tools, at least two baffles axially staggered in the depth of the comminution space are arranged, the baffle surface following in the axial conveying direction projecting beyond the axial projection of the previous baffle surface. In addition, the invention discloses a method for optimizing the size and position of the impact surfaces of a comminution machine according to the invention.
