The length of the sides of the elements forming the circumference of the grinding path amounts to 1/10 to 1/30 of the circumference of the grinding path.

Abstract (de)

Die Erfindung betrifft ein Element einer trommelförmigen Zerkleinerungsbahn, wie sie beispielsweise in gasdurchströmten Zerkleinerungsmaschinen mit einem rotierenden Schlagradsystem Verwendung finden. Die Oberfläche eines erfindungsgemäßen Elementes weist im Wechsel Abschnitte (9, 10) mit und ohne Profilierung auf, wobei die Profilierung aus nebeneinander angeordneten Profilleisten (11, 11') mit dazwischenliegenden Vertiefungen (12, 12') besteht und die Profilleisten (11, 11') gegenüber der in Rotationsrichtung angeordneten Symmetrieachse (2) eines Elements um den Winkel geneigt sind. Zum Erhalt eines möglichst sortenreinen Feinguts fluchten gemäß der Erfindung die Profilleisten (11, 11') eines profilierten Abschnitts (9) entweder mit den Profilleisten (11, 11') eines nachfolgenden profilierten Abschnitts (9) oder mit den Vertiefungen (12, 12') zwischen den Profilleisten (11, 11') eines nachfolgenden profilierten Abschnitts (9). <IMAGE>
