Abstract

Die Erfindung betrifft ein Siebaggregat mit drehenden Siebsternen (10), welche auf mehreren, zueinander ausgerichteten Siebwellen angeordnet sind, wobei die Siebsterne jeweils mehrere an einer Nabe (11) angeordnete und in Drehrichtung aufeinanderfolgende Arme (12) aufweisen. Erfindungsgemäß sind zwischen aufeinanderfolgenden Armen (12) auf der Nabe (11) Stege (18) angeordnet, wobei die Stege in Axialrichtung der Siebsterne geringere Abmessungen aufweisen als die hierzu jeweils benachbarten Arme.

Figure imgaf001
The invention relates to a Siebaggregat with rotating screen stars (10) which are arranged on a plurality of mutually aligned screen shafts, wherein the screen stars each have a plurality of on a hub (11) arranged and in the direction of rotation successive arms (12). According to the invention, webs (18) are arranged between successive arms (12) on the hub (11), wherein the webs have smaller dimensions in the axial direction of the screen stars than the arms respectively adjacent thereto.
