Abstract

Bei einem Verfahren und einer Vorrichtung zum Trennen eines Staubgemisches aus zwei Stäuben unterschiedlicher Dichten in seine Staubbestandteile wird eine partielle Fluidisierung des leichteren Staubes durchgeführt, wobei eine Vertikalkomponente einer Fluidisierungsgasmenge derart eingestellt ist, dass diese die Fluidisierung des einen Staubes bewirkt, jedoch niedriger ist als die Vertikalkomponente der Fluidisierungsgasmenge, bei der das Fluidisieren des anderes Staubes auftritt.

Figure imgaf001
In a method and apparatus for separating a dust mixture of two dusts of different densities into its dust constituents, a partial fluidization of the lighter dust is performed, wherein a vertical component of a fluidizing gas quantity is adjusted to cause the fluidization of the one dust but lower than that Vertical component of Fluidisierungsgasmenge at which the fluidization of the other dust occurs.
