Description
Die Erfindung betrifft ein Verfahren zur Aufberei tung einer bei Betrieb einer Hammerbrecher- bzw. Shredderanlage anfallenden, inhomogenen Gutfraktion, vorzugsweise einer Shredder- Leichtfraktion, nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for preparation device when operating a hammer crusher or Inhomogeneous material fraction resulting from the shredder system, preferably a shredder light fraction, after which Preamble of claim 1.
Nach bekannten Verfahren wird die Shredder-Leicht fraktion in Hammer- oder Schlägermühlen zerkleinert. Im Ergebnis dieser Zerkleinerungsprozesse entsteht ein Produkt stark variierender Korn- bzw. Stückgröße, des sen Materialkomponenten ihrerseits eine breite, sich zu mindest teilweise überlappende Korn- bzw. Stückgrö ßenverteilung aufweisen, unabhängig davon, in welcher Korn- bzw. Stückgröße eine jede dieser Materialkom ponenten für eine Weiterverwendung derselben vorlie gen sollte. So werden Metalle bei längerer Verweildau er in vorgenannten Mühlen zum Teil so stark zerklei nert, daß die Metalle einer Separation von anderen Ma terialkomponenten nicht mehr zugänglich sind. Ande rerseits ist bei kürzerer Verweilzeit der Aufschlußgrad bestimmter Materialkomponenten-Gemische noch nicht so groß, daß die Materialkomponenten dieser Ge mische voneinander getrennt werden könnten.According to known methods, the shredder is light fraction crushed in hammer or beater mills. The result of these shredding processes is a Product of widely varying grain or piece size, des The material components in turn have a wide at least partially overlapping grain or piece size have external distribution, regardless of which Grain or piece size of each of these materials components for further use of the same should. This is how metals become with longer stays in some of the above-mentioned mills it is crushed so strongly nert that the metals of a separation from other Ma material components are no longer accessible. Ande on the other hand, the degree of disruption is with a shorter dwell time certain material component mixtures still not so large that the material components of this Ge mix could be separated.
Versuchsweise sind auch Schneidwalzenmühlen zum Einsatz gekommen, die allerdings einem hohen Ver schleiß unterliegen.Experimental are also cutting roller mills for Use come, which, however, a high ver subject to wear.
Daher liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur Aufbereitung einer bei Betrieb einer Hammerbrecher- bzw. Shredderanlage anfallenden, in homogenen Gutfraktion zu schaffen, mit dem ein der vorgesehenen Verwendung der einzelnen Materialkom ponenten der Gutfraktion weitgehend angepaßter Auf schluß bzw. Zerkleinerungsgrad erreicht wird.The invention is therefore based on the object Process for processing a while operating a Hammer crusher or shredder system, in to create a homogeneous fraction with which one of the intended use of the individual material comm Components of the good fraction largely adapted to conclusion or degree of comminution is reached.
Diese Aufgabe wird erfindungsgemäß gelöst, indem bei einem Verfahren gattungsgemäßen Typs die aufzu bereitende Gutfraktion in einer stabförmige Mahlkör per enthaltenden Trommelmühle aufgeschlossen bzw. zerkleinert wird.This object is achieved by in a method of the generic type Preparing good fraction in a rod-shaped grinding media disrupted by the contained drum mill or is crushed.
Mit der Erfindung ist insbesondere der Vorteil ver bunden, daß in einer stabförmige Mahlkörper enthal tenden Trommelmühle die aufzubereitende, inhomoge ne Gutfraktion in Vorbereitung der Trennung ihrer Be standteile aufgeschlossen werden kann, ohne über die sen Aufschluß eine unerwünschte weitere Zerkleine rung einzelner Materialkomponenten hervorzurufen.With the invention, the advantage is particularly ver bound that contain in a rod-shaped grinding media the inhomogeneous drum mill to be processed ne good fraction in preparation for the separation of their Be components can be unlocked without going through the Sen digestion an unwanted further crushing induction of individual material components.
Im Ergebnis des Aufschlusses der inhomogenen Gut fraktion und infolge des unterschiedlichen Zerkleine rungsverhaltens der Bestandteile dieser Gutfraktion entstehen Materialkomponenten unterschiedlicher Korn- bzw. Stückgröße, so daß in zweckmäßiger Ver fahrensdurchführung eine Trennung dieser Material komponenten nach Korn- bzw. Stückgrößen erfolgen kann.As a result of the disintegration of the inhomogeneous good fraction and due to the different crushing behavior of the components of this good fraction material components arise differently Grain or piece size, so that in a convenient Ver conduct a separation of this material components according to grain or piece sizes can.
Dabei wird eine solche Trennung insbesondere zur Verringerung der im Verfahren benötigten Vorrichtun gen bevorzugt in der mit stabförmigen Mahlkörpern versehenen Trommelmühle durchgeführt. Der Einbau von Leitblechen im Gutaustragsbereich einer solchen Mühle erhöht den erreichbaren Klassierungseffekt.Such a separation is used in particular Reduction of the devices required in the procedure gene preferred in that with rod-shaped grinding media provided drum mill performed. The installation of baffles in the discharge area of such Mühle increases the achievable classification effect.
Ist der Zerkleinerungsgrad der Komponenten der aufbereiteten Gutfraktion für deren weitere Verwen dung noch nicht ausreichend, so wird bevorzugt jede dieser Materialkomponenten zweckmäßig in minde stens einem weiteren Durchlauf in der mit stabförmigen Mahlkörpern versehenen Trommelmühle auf eine ent sprechende Endgröße nachzerkleinert.Is the degree of comminution of the components of the processed good fraction for their further use not sufficient, everyone is preferred expedient of these material components in mind at least one more pass in the with rod-shaped Grinding media provided drum mill on a ent speaking final size.
Zur Beeinflussung der Struktur der aus dem Verfah ren hervorgehenden Materialkomponenten erfolgt in Abhängigkeit vom Aufschluß bzw. Zerkleinerungsver halten der aufzubereitenden Gutfraktion eine Verände rung der Materialart und/oder der Geometrie der Stäbe der Trommelmühle.To influence the structure of the process ren emerging material components takes place in Dependence on the digestion or crushing ratio keep the good fraction to be processed a change tion of the material type and / or the geometry of the bars the drum mill.
Eine besonders wirkungsvolle Beeinflussung des Ver fahrensergebnisses wird erreicht, indem die Materialart und/oder die Geometrie der Stäbe der Trommelmühle in Abhängigkeit vom Aufbereitungsergebnis der Me talle verändert werden.A particularly effective influence on the ver Driving result is achieved by the material type and / or the geometry of the drum mill bars depending on the processing result of the Me talle be changed.
