Abstract

Metal sepn. from dry mixts. of metallic components and inorganic and/or organic components involves subjecting the mixts. to roller crushing treatment and to an additional shear and frictional force, the metallic components then being sieved from the other components. Also claimed is an appts. for carrying out the above process, consisting of a double roller, a grinding mill or a rolling mill with forced feed.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Abtrennen von Metallen aus Stoffgemischen gemäß dem Oberbegriff des Hauptanspruches.The present invention relates to a method for separation of metals from mixtures of substances according to the preamble of Main claim.

Aus Stoffgemischen, beispielsweise aus Müll oder aufgearbeiteten Müllgemischen, beispielsweise Pyrolyse oder Verbrennungsrückständen, ist es mit einfachen Verfahren nicht möglich, Metall abzutrennen. Lediglich Eisenmetalle können mittels Magneten einfach aus Stoffgemischen entfernt werden, bei anderen Metallen, die keine magnetischen Eigenschaften aufweisen, ist dies nicht möglich. Deshalb wurden zur Abtrennung von Metallen aus solchen Gemischen bisher umständliche Verfahren eingesetzt, beispielsweise Flotationsverfahren, die beispielsweise die Metallkomponenten aufgrund ihrer Dichteunterschiede abtrennen. Solche Verfahren haben sich aber in der Praxis nicht durchsetzen können.From mixtures of materials, for example from rubbish or processed waste mixtures, for example pyrolysis or Combustion residues, it is not with simple procedures possible to separate metal. Only ferrous metals can can be easily removed from mixtures of materials using magnets, for other metals that have no magnetic properties this is not possible. That is why Separation of metals from such mixtures so far cumbersome procedures used, for example Flotation processes, for example the metal components separate due to their density differences. Such procedures have not been able to prevail in practice.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zu schaffen, mit dem auf einfache Weise metallische Komponente aus Stoffgemischen abgetrennt werden können.The object of the present invention is to provide a method create with the easily metallic component can be separated from mixtures of substances.

Gelöst wird diese Aufgabe durch ein gattungsgemäßen Verfahren gemäß dem Oberbegriff des Hauptanspruchs erfindungsgemäß durch die Lösungsmerkmale im kennzeichnenden Teil des Hauptanspruches. Die Unteransprüche geben bevorzugte Ausgestaltungen der Erfindung wieder.This task is solved by a generic method according to the preamble of the main claim according to the invention the solution features in the characteristic part of the  Main claim. The subclaims give preferred Embodiments of the invention again.

Zur Durchführung des Verfahrens ist es erforderlich, daß die zu trennenden Stoffgemische so trocken sind, daß bei der kombinierten Walzquetschbehandlung zusätzlich zur Walz- und Quetschbeanspruchung eine scherende und reibende Beanspruchung des Behandlungsgutes auftritt. Dies ist im allgemeinen bei Feuchtigkeitsgehalten von nicht mehr als 5% der Fall. Vorzugsweise sollte aber der Wassergehalt noch weiter herabgesetzt werden, beispielsweise auf 3% oder weniger.To carry out the method it is necessary that the mixtures of substances to be separated are so dry that the combined rolling crushing treatment in addition to rolling and Squeezing stress is a shearing and rubbing stress of the material to be treated occurs. This is generally the case with Moisture levels of no more than 5% of the case. Preferably, however, the water content should go even further can be reduced, for example to 3% or less.

Das getrocknete Gut wird dann neben einer Walz-Quetschbehandlung auch einer zusätzlichen scherenden und reibenden Kraft unterzogen. Dies kann beispielsweise durch mühlenähnliche Einrichtungen bewirkt werden, beispielsweise durch Doppelrollen, Kollergänge, Walzeinrichtungen mit Zwangsführungen, Wälzmühlen, Rollenmühlen, Kugelmühlen, Ringwalzenmühlen, Walzwerke und dergleichen. Diese Vorrichtungen sind bekannt. Sie wurden aber bisher nicht zur Trennung von Gemischen aus Metallen und Nichtmetallen verwendet.The dried good is then next to one Roll crushing treatment also an additional shearing and subjected to abrasive force. This can be done, for example mill-like devices are effected, for example through double rollers, pan mills, rolling devices with Positive guidance, roller mills, roller mills, ball mills, Ring roller mills, rolling mills and the like. These Devices are known. So far they have not become Separation of mixtures of metals and non-metals used.

Durch das erfindungsgemäße Verfahren werden die metallischen Bestandteile elastisch verformt und dadurch ihr lichter Querschnitt vergrößert, während die nicht-metallischen, anorganischen und organischen Bestandteile zerkleinert werden. Dadurch ergeben sich unterschiedliche Korngrößen, so daß die metallischen Bestandteile von den übrigen Bestandteilen abgesiebt werden können.With the method according to the invention, the metallic Components deformed elastically and thereby your lights Cross-section enlarged, while the non-metallic, inorganic and organic components are crushed. This results in different grain sizes, so that the metallic components from the other components can be screened.

Die erfindungsgemäße Walz-Quetschbehandlung kann mit der anschließenden Absiebung auch kombiniert werden, wenn entsprechende Vorrichtung eingesetzt werden, die diese beiden Vorgänge vereinigen. Dies ist beispielsweise bei sogenannten Siebkollergängen der Fall, bei denen ein Teil der rotierenden Mahlbahn Löcher aufweist, durch welche das durch die Zentrifugalkraft nach außen beförderte Mahlgut durchfallen kann.The roller crushing treatment according to the invention can be carried out with the subsequent screening can also be combined if Appropriate device can be used, these two Unite operations. This is the case with so-called Sieve roller conveyors the case in which a part of the rotating Grinding track has holes through which the through Centrifugal force through which the regrind conveyed to the outside falls through  can.

Der erfindungsgemäßen Behandlung kann zur Abtrennung der Eisenmetalle eine Magnetbehandlung vorgeschaltet werden. Diese Magnetbehandlung kann aber auch nach der Zerkleinerung vor der Siebung durchgeführt werden.The treatment according to the invention can be used to separate the Ferrous metals can be preceded by a magnetic treatment. These Magnetic treatment can also be done after shredding before Screening to be carried out.

Das von Metallen befreite anorganische bzw. organische Material kann gelagert werden, es kann bei einem höheren Anteil an Kohlenstoff auch als Brennmaterial verwendet werden.The inorganic or organic freed from metals Material can be stored, it can be stored at a higher level Share of carbon can also be used as fuel.

Das erfindungsgemäße Verfahren eignet sich insbesondere zur Abtrennung von Metallen aus Pyrolyserückständen, wie sie beispielsweise bei der Müllpyrolyse anfallen.The method according to the invention is particularly suitable for Separation of metals from pyrolysis residues as they do for example in waste pyrolysis.
