Abstract

Im Betrieb werden die Konzentratorebene (3) und die Steinab­ saugebene (4) in Schwingung versetzt. Luft wird bei (19) abge­ saugt. Die durch die Konzentratorebene (3) durchströmende Luft fluidisiert das durch den Zulauf (13) eingelassene Korngut, so dass es gleichmässig in Neigungsrichtung abfliesst. Spezifisch schwere Bestandteile ordnen sich an der Unterseite, spezifisch leichte Bestandteile ordnen sich an der Oberseite des Stromes. Im Durchfallbereich (7) fallen die spezifisch schweren Bestandteile nach unten. Spezifisch leichte Bestandteile wandern zum Leichtfraktionsauslass (14). Beim Fall nach unten werden die spezifisch schweren Bestandteile durch die Luft­ strömung in den Abteilen (10) abgebremst, können aber wegen der Querstege (11) nicht in Neigungsrichtung abfliessen. Sie werden daher in den Abteilen verwirbelt, bevor sie durch die Oeffnungen der zweiten Strömungsmaske (9) fallen. Durch diese Verwirbelung wird für eine gleichmässige turbulente Luftströ­ mung durch die erste Strömungsmaske (8) gesorgt. Dadurch wird eine Störung der Schichtung des Korngutstroms vermieden. Da ferner eine gleichmässige Beschickung der Steinausleseebene (4) erreicht wird, wird der Steinauslesevorgang verbessert.
