Abstract (en)

The unit has a static cascade separator as a pre-sifting zone (11), which has at least one rotating basket (19) with turbo-elements of a dynamic sifting part rotating in a sifting casing (10) arranged downstream of it. Inlets are provided for sifting air (12) and sifted goods (16) and outlets are provided for sifting air and for fine, medium (22) and coarse (14) fractions. A bypass conductor (18) extends from an intermediate area between the static and dynamic parts, to divert a part of the sifting air flow. The bypass flow has a collector to separate the solids contained in the bypass gas flow or to guide it to a further processing step for further processing.

Abstract (de)

Um eine Sichtereinrichtung mit integriertem statischen Sichterteil und dynamischen Sichterteil mit wenigstens einem rotierbar angeordneten Stabkorb zu auszubilden, daß die beiden Sichterteile optimal aufeinander abgestimmt wirtschaftlich betrieben werden können, insbesondere bei feuchtem zu trocknendem Sichtgut, wird erfindungsgemäß vorgeschlagen, vom Zwischenbereich zwischen dem statischen Teil (11) und dem dynamischen Teil (19) der Sichtereinrichtung zum Abzug eines Teilstroms des Sichtluftstroms/Sichtgasstroms eine Bypassleitung (18) abgehen zu lassen, und nur noch die restliche Sichterabluft (20) des statischen Sichterteils (statischer Kaskadensichter oder V-Sichter) in den dynamischen Sichterteil mit dem wenigstens einen rotierbar gelagerten Stabkorb (19) einzuführen. <IMAGE>
