Abstract (de)

Die Erfindung betrifft ein Verschleißelement für Zerkleinerungsmaschinen, deren rotierender Messerkranz eine Trägerscheibe und einen dazu koaxial angeordneten Trägerring (1) umfasst, wobei Trägerscheibe und Trägerring (1) über axial dazwischenliegende, gleichmäßig über den Umfang verteilte Messerträger verbunden sind. Das Verschleißelement (19) besteht aus einer Platte (20) mit ringsektorförmiger Gestalt, die jeweils den inneren Umfang (4) der Außenseite (15) des Trägerrings (1) bedeckt und im Bereich des Spalts (6) zwischen zwei Messerträgern (3) über die Dicke des Verschleißelements (19) zum Trägerring (1) hin eine Schräge (24) aufweist. Gemäß der Erfindung ist die Schräge (24) mit Hilfe einer Verschleißlippe (25) zum Schutz des Trägerrings (1) verlängert, so dass dadurch der Trägerring (1) über seine gesamte Dicke geschützt ist. Dadurch gelingt es, einem übermäßigen Verschleiß des Trägerrings (1) vorzubeugen. <IMAGE>
