  In einem geschlossenen Trommelgehäuse rotierende Siebtrommel. 



   Im Patente Nr. 107397 ist eine in einem geschlossenen Trommelgehäuse rotierende Siebtrommel beschrieben, die am äusseren Umfange mit Schienen versehen ist, welche die Rotation der Masse unterstützen. Die Wirkung dieser Schienen reicht jedoch nicht aus, auch der im Inneren der Siebtrommel befindlichen Masse eine befriedigende Rotation zu erteilen. 



   Den Gegenstand der vorliegenden Erfindung bildet nun die Anordnung von Schaufeln oder Mitnehmern auch an der Innenwand der Siebtrommel, wodurch die Masse an beiden Seiten der   Siebfläche   mit annähernd derselben Geschwindigkeit rotiert und beim Durchdrücken der Masse durch das Sieb Stösse und Wirbelbildungen vermieden sind. 



   Die Zeichnung stellt eine beispielsweise Ausführung der Mitnehmeranordnung dar. 1 ist die Siebtrommel mit den äusseren Schienen 3 und den inneren Mitnehmern 4, die z. B. mit den die Siebplatten tragenden Rippen 5 verbunden sind. Die Masse tritt durch den Zufuhrstutzen 6 in das Trommelgehäuse 2. 



  Die gesiebte Masse tritt durch den Auslaufstutzen 7 aus, wogegen die groben Bestandteile durch die Stirn- öffnung 8 die Vorrichtung verlassen.

  Rotating screening drum in a closed drum housing.



   In the patent no. 107397 a rotating sieve drum in a closed drum housing is described, which is provided on the outer circumference with rails which support the rotation of the mass. However, the effect of these rails is not sufficient to give the mass located inside the sieve drum a satisfactory rotation.



   The subject of the present invention is the arrangement of blades or drivers also on the inner wall of the sieve drum, whereby the mass rotates on both sides of the sieve surface at approximately the same speed and shocks and vortices are avoided when the mass is pushed through the sieve.



   The drawing shows an example embodiment of the driver arrangement. 1 is the sieve drum with the outer rails 3 and the inner drivers 4, which, for. B. are connected to the ribs 5 carrying the sieve plates. The mass enters the drum housing 2 through the feed nozzle 6.



  The sieved mass exits through the outlet connection 7, whereas the coarse components leave the device through the front opening 8.

PATENT-ANSPRUCH : In einem geschlossenen Trommelgehäuse rotierende Siebtrommel, bei welcher eine Pulsation der Masse durch die Siebfläche dadurch erreicht wird, dass der radiale Abstand der Wände des Trommelgehäuses von der Siebfläche dem Unfange des Trommelgehäuses entlang variiert, dadurch gekennzeichnet, dass zur Unterstützung der Rotation der Masse die Siebtrommel (1) auch innen mit Schaufeln oder Mitnehmern (4) versehen ist. EMI1.1 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: In a closed drum housing rotating sieve drum, in which a pulsation of the mass through the sieve surface is achieved in that the radial distance of the walls of the drum housing from the sieve surface varies along the circumference of the drum housing, characterized in that to support the rotation of the mass, the sieve drum (1) is also provided with blades or drivers (4) on the inside.
