Abstract

Bei einem Verfahren zur Dichtetrennung eines Schütt­ gutgemisches bestehend aus einer feinteilig und grobteilig vorliegenden ersten Komponente geringeren spezifischen Gewichtes und mindestens einer zweiten Komponente höheren spezifischen Gewichtes, insbesondere gemahlener Rohkohle, wird der Feinanteil (FK) der ersten Komponente in einer Schwingrinne (1) mit einem Gas (L) fluidisiert und fließt in einer Richtung ab. Das Restgut (GK + P + B) wird in die andere Richtung gefördert. Schließlich wird aus dem Restgut mindestens der Grobanteil (GK) der ersten Komponente abgetrennt. In a method for density separation of a bulk well mixed consisting of a fine and coarse present first component lower specific Weight and at least a second component higher specific weight, especially ground Raw coal, the fine fraction (FK) of the first component is in a vibrating trough (1) fluidized and flows with a gas (L) in one direction. The remaining good (GK + P + B) is in the promoted other direction. Eventually, the remaining good at least the coarse fraction (GK) of the first component separated.

Um die Abtrennung des Grobanteils verfahrensmäßig zu vereinfachen, wird vorgeschlagen, daß zumindest die Abtrennung des Grobanteils aus dem im wesentlichen keinen Feinanteil (FK) mehr aufweisenden Restgut mittels der gerichteten Schwingbewegung der Schwingrinne (1) erfolgt. In order to procedurally separate the coarse fraction simplify, it is proposed that at least the Separation of the coarse fraction from the residual material no longer having a fine fraction (LC) the directed swinging movement of the swinging channel (1) he follows.

Bei einer Vorrichtung zur Durchführung des Verfahrens wird erfindungsgemäß die erforderliche Trenneinrichtung die Schwingrinne integriert. In a device for performing the method is the required separation device according to the invention the vibrating channel integrated.
