Description
Verfahren zum Naßklassieren und/oder -sortieren von grob- bis feinkörnigen Mineralien oder sonstigen Feststoffen Im Hauptpatent 1017102 ist ein Verfahren und eine Vorrichtung zum Naßklassieren und/oder -sortieren von grob- bis feinkörnigen Mineralien oder sonstigen Feststoffen beschrieben, nach welchem innerhalb einer Flüssigkeit zwischen Magneten, insbesondere Dauermagneten, eine porös zusammenhängende elastische Schicht aus magnetisierbaren Teilchen (z. B. Magnetit, Ferrosilizium) gebildet wird, auf die das Rohgut aufgegeben wird und durch Hindurchfallen seiner gröberen und schwereren Bestandteile durch die gebildete, als Trenn- bzw. Sperrzone dienende Schicht fraktioniert wird.Process for wet classifying and / or sorting from coarse to fine-grained Minerals or other solids In the main patent 1017102 is a process and a device for wet classifying and / or sorting from coarse to fine-grained Minerals or other solids described after which within a Liquid between magnets, especially permanent magnets, a porous coherent elastic layer made of magnetizable particles (e.g. magnetite, ferrosilicon) is formed, to which the raw material is abandoned and by falling through its coarser and heavier components through the formed, as a separation or exclusion zone serving layer is fractionated.
Es wurde nun gefunden, daß die Fraktionierung weiterhin dadurch günstig beeinflußt werden kann, wenn nach dem Vorschlag vorliegender Erfindung durch Einblasen von Gasen (z. B. Preßluft) der Auftrieb der Flüssigkeit unterstützt wird.It has now been found that fractionation continues to be beneficial as a result can be influenced if according to the proposal of the present invention by blowing the buoyancy of the liquid is supported by gases (e.g. compressed air).
Das Einblasen der Gase kann durch eine Düse erfolgen bzw. durch mehrere Düsen, die auf der von der Flüssigkeit bedeckten Fläche verteilt sind. An Stelle von Düsen können aber auch andere, dem gleichen Zweck dienende Vorrichtungen verwendet werden.The gases can be blown in through one nozzle or several Nozzles distributed on the surface covered by the liquid. Instead of of nozzles, however, other devices serving the same purpose can also be used will.
Der durch das Einblasen der Gase der Flüssigkeit gegebene zusätzliche Auftrieb beeinflußt in der Weise vorteilhaft die Fraktionierung, daß auch noch eine Trennung der gröberen und schwereren Bestandteile unterhalb der im Hauptpatent beschriebenen elastischen Schicht aus magnetisierbaren Teilchen eintritt und die elastische Schicht gegen den Fallstrom des Rohgutes gestützt wird.The additional liquid given by the blowing in of the gases Buoyancy influences the fractionation in such a way that also another Separation of the coarser and heavier components below those described in the main patent elastic layer of magnetizable particles enters and the elastic layer is supported against the falling flow of the raw material.
