Description

Die Erfindung betrifft ein Verfahren zur Gewinnung von Nichteisen-Metallen aus dem in Shredderanlagen zerkleinerten Schrott, wie gebrauchte Automobile, bei welchem Verfahren nach Abtrennung der magnetischen Fraktion die nichtmagnetische Fraktion einer Windsichtung zur Entfernung der Leichtbestandteile unterworfen wird und das verbleibende Gemenge in die Fraktionen Nichtmetallisches, wie Glas, Gummi, Holz, Kunststoff und Nichteisen-Metalle, wie Zink, Aluminium, zerlegt wird. Die Korngröße des dabei neben der magnetischen Fraktion und dem flugfähigen Material der Windsichtung anfallenden Gemenges aus Nichtmetallischem und Nichteisen-Metall reicht bis zu 100 mm.The invention relates to a method for the extraction of non-ferrous metals from the in shredder plants shredded scrap, such as used automobiles, in which process after separation of the magnetic Fraction the non-magnetic fraction is subjected to air classification to remove the light components and the remaining mixture in the fractions of non-metallic, such as glass, rubber, wood, plastic and non-ferrous metals such as zinc, aluminum, is decomposed. The grain size of the besides the magnetic Fraction and the airworthy material of the wind sifting accumulating mixture of non-metallic and Non-ferrous metal extends up to 100 mm.

Bisher wird aus diesem Gemenge auf einem Klaubeband das Nichteisenmetall, hauptsächlich Aluminium und Zink, von Hand ausgelesen. Dabei werden zweifellos nur die größeren Stücke erfaßt, erhebliche Anteile an Bruchstücken in der Größe unter 15 mm werden nicht ausgeklaubt Man rechnet mit Verlusten von 40—50% der vorlaufenden NE-Metallmenge. Darüber hinaus sind die Lohnkosten nicht unerheblich.
Es ist der Versuch gemacht worden, mit demSo far, the non-ferrous metal, mainly aluminum and zinc, has been hand-picked from this mixture on a claw conveyor. In doing so, only the larger pieces are undoubtedly covered, considerable proportions of fragments less than 15 mm in size are not picked. Losses of 40-50% of the non-ferrous metal quantity in front are expected. In addition, the wage costs are not insignificant.
An attempt has been made with the

ίο Verfahren der Schwimm-Sink-Scheidung eine wirtschaftliche Trennung der Komponenten herbeizuführen. Als Beschwerungsmittel für die Trübe wurde Ferrosilizium verwendet. Das Verfahren hat sich nicht durchsetzen können, da neben anderen Schwierigkeitenίο Procedure of sink-swim divorce an economic one To bring about separation of the components. As a weighting agent for the turbidity was Ferrosilicon used. The procedure was not able to prevail because of other difficulties

is auch die Verunreinigung des Schrottes mit Ferrosilizium nachteilig istis also the contamination of scrap with ferrosilicon is disadvantageous

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu finden, bei welchem die vorher geschilderten Nachteile vermieden sind und welches die wirtschaftliche Gewinnung der NE-Metalle bei der Aufbereitung des Schrotts ermöglichtThe invention is based on the object of finding a method in which the previously described Disadvantages are avoided and which the economic extraction of the non-ferrous metals in the Processing of the scrap allows

Erfindungsgemäß wird diese Aufgabe bei einem Verfahren eingangs genannter Gattung dadurch gelöst, daß das verbleibende Gemenge zunächst bei 20 mm gesiebt, das Oberkorn mittels Schleuderband nach dem spezifischen Gewicht in die Fraktionen Zink, Aluminium und Nichtmetallisches zerlegt und das Unterkorn durch weiteres Sieben in zwei Korngrößenfraktionen aufgeteilt wird, welche zwei Korngrößenfraktionen nach bekannten, die unterschiedlichen spezifischen Gewichte nutzenden Verfahren der Schwerkrafttrennung ebenfalls in die Fraktionen Zink, Aluminium und Nichtmetallisches getrennt werden.
Die Geschwindigkeit des Schleuderbandes ist dabeiAccording to the invention, this object is achieved in a method of the type mentioned at the outset in that the remaining mixture is first sieved at 20 mm, the upper grain is broken down into the fractions of zinc, aluminum and non-metallic by means of a centrifugal belt according to the specific weight and the lower grain is divided into two grain size fractions by further sieving which two grain size fractions are also separated into the fractions zinc, aluminum and non-metallic according to known methods of gravity separation that use the different specific weights.
The speed of the sling belt is included

J5 so eingestellt, daß beim Abwerfen wegen der unterschiedlichen kinetischen Energie eine Trennung in Nichtmetallisches, das zuerst herunterfällt, Aluminium mit einem spezifischen Gewicht von ca. 30 N/dm3 und Zink mit einem spezifischen Gewicht von ca. 70 N/dm3 J5 is set in such a way that when it is thrown, due to the different kinetic energy, a separation into the non-metallic, which falls first, aluminum with a specific weight of approx. 30 N / dm 3 and zinc with a specific weight of approx. 70 N / dm 3

■to erfolgt.■ to takes place.

Das Sieben des Unterkorns in 2 Korngrößenfraktionen erfolgt zweckmäßigerweise bei 5 mm. Beide Fraktionen werden getrennten Aufbereitungsaggregaten zugeführt, wie sie dem Fachmann bekannt sind. Die dafür vorgesehenen Aggregate sind Geräte, die das unterschiedliche spezifische Gewicht der Bestandteile zur Trennung nutzen. So können z. B. Naß- und Luft-Setzmaschinen oder Windsichter eingesetzt werden. The sieving of the undersized grain into 2 grain size fractions is expediently carried out at 5 mm. Both Fractions are fed to separate processing units, as they are known to the person skilled in the art. the The units provided for this purpose are devices that have the different specific gravity of the components use for separation. So z. B. wet and air setting machines or wind sifters can be used.
