Abstract

Um eine Siebmaschine zur Trennung von siebfähigen Gütern, bestehend aus einem Maschinengehäuse (1), mindestens einem in diesem angeordneten Siebdeck (5,6), welches mittels einer Aufgabevorrichtung (7) beschickbar ist, mindestens einem Grobgutabgabeteil (2,3), über das vom Siebdeck zurückgehaltenes Grobgut abgezogen wird, sowie einem Feingutabgabeteil (4), über das durch das Siebdeck (6) abgetrenntes Feingut abgezogen wird, zur Verfügung zur stellen, die bei relativ geringer Baugröße mit geringem Energieverbrauch eine Entstaubung von Schüttgütern ermöglicht, wird vorgeschlagen, dass im Feingutabgabeteil (4) ein Querstromsichter (8) integriert ist, mittels dessen das Feingut entstaubbar ist.
