Walzen für ZerkleinerungsvorrichtungenRollers for crushers

Die vorliegende Erfindung bezieht sich, auf Walzen für Zerkleinerungsvorrichtungen zum Zerkleinern von Kunststoff, Metallabfallen oder dgl.The present invention relates to rollers for shredding devices for shredding plastic, metal waste or like

Es ist bekannt, derartige Walzen mit einem Verschleißmantel zu versehen. Es werden zu diesem Zwecke in erster Linie gegossene Verschleißringe verwendet. Diese gegossenen Verschleißringe sind jedoch relativ kostspielig, so daß man auf die Verwendung von Verschleißblechen übergegangen ist. Hierbei wird ein Grobblech zu einem Zylinder gebogen und an den Stoßkanten verschweißt. Da das Material, aus dem der Verschleißmantel bestehen muß, relativ hart ist, sind seine Schweißeigenschaften jedenfalls dann sehr schlecht, wenn man aus Kostengründen einen Verschleißmantel aus einem normalen harten Kohlenstoffstahl wählt. Außerdem ergeben sich beim Aufschrumpfen eines harten Verschleißbleches auf den Walzengrundkörper Schwierigkeiten. So ist eine sehr genaue Bearbeitung der Oberflächen erforderlich, weil der harte Versehleißkörper sonst keinen flächigen Kontakt mit dem Grundkörper erhält.It is known to provide such rolls with a wear jacket Mistake. Cast wear rings are primarily used for this purpose. These are cast wear rings however, relatively expensive, so that one has switched to the use of wear plates. This is a heavy plate bent into a cylinder and welded at the joint edges. Since the material from which the wear jacket must be made, is relatively hard, its welding properties are in any case very poor if you have a wear jacket for reasons of cost chooses from a normal hard carbon steel. In addition, a hard wear plate is shrunk on difficulties on the roller body. A very precise machining of the surfaces is necessary because of the hard wear body otherwise there is no surface contact with the base body.

Die vorliegende Erfindung vermeidet die Nachteile der bekannten Zerkleinerungswalzen dadurch, daß auf den Walzengrundkörper ein Verbundgußblech aufgebracht ist. Dies hat den Vorteil, daß die Schweißverbindung der beiden Stoßenden des Verbundgußbleches einwandfrei ist, weil die Stärke der Schweißverbindung in erster Linie durch die weiche innere Grundschicht gegeben ist, während die darüberliegende harte Verbundgußschicht kaum zur Festigkeit der Schweißnaht beitragen muß, so daß es auf deren Schweißeigenschaften nicht oder nur im untergeordneten Umfang ankommt.The present invention avoids the disadvantages of the known ones Crushing rollers in that a composite cast sheet is applied to the roller base. This has the advantage that the The welded connection of the two butt ends of the composite cast sheet is flawless, because the strength of the welded connection is primarily is given by the soft inner base layer, while the overlying hard composite cast layer hardly contributes to the strength of the Weld seam must contribute so that it does not depend on their welding properties or only to a minor extent.

Me Erfindung ist anhand der anliegenden Eigur erläutert, die einen Querschnitt durch den Walzenkörper darstellt.Me invention is explained with reference to the attached Eigur, the represents a cross section through the roller body.

Die Bezugsziffer 1 bezeichnet den Walzenkörper, der vorzugsweise als "Vollkörper ausgebildet ist. Das Yerbundgußblech besteht aus einer dünneren harten üißenschicht 2 und einer weicheren, aber zähen Innenschicht 3. "Vorzugsweise wird die Innenschicht dicker ausgeführt als die harte äußere Verschleißschicht. Die Festigkeit der Schweißnaht 4 wird vorzugsweise durch die zähe innere Schicht 3 gewährleistet.The reference number 1 designates the roller body, which is preferably designed as a "solid body. The cast composite sheet consists of a thinner, hard outer layer 2 and one softer but tough inner layer 3. "Preferably the Inner layer made thicker than the hard outer wear layer. The strength of the weld seam 4 is preferably ensured by the tough inner layer 3.
