Description

Die Erfindung betrifft aine Ringwalzenmühle an sich bekannter Bauart. Bei Mühlen dieser Art war es nicht ausgeschlossen, daß bei einean mehr oder wendiger großen Pendeln das Mahlringes dieser an die Scnledßleisten des MaMgehäuses derart aneckte, daß durch die Reibung zündende Metallteilchen abgeschliffen wunden. Hierbei 'bestand die Gefahr, namentlich bei der Erzeugung von Kohlenstaub, daß aine Entzündung in der Mühle hervorgerufen wurde.The invention relates to a ring roller mill of a known type. At mills of this kind it was not ruled out that with one of the more or more agile large pendulums the grinding ring of these to the cutting strips of the MaMgehäuses in such a way that igniting metal particles are abraded by the friction wounds. There was a danger here, especially in the production of coal dust, that an inflammation was caused in the mill.

Durch dlie Erfindung .soll diesem Mangel abgeholfen wenden. Es geschieht dies dadurch, daß an den Stellen, an denen infolge das Pendeins des Mahlringes dieser gegen das Gehäuse stößt, Einlagen aus einem nichtfunkenden Stoffe, z. B. Pockholz, Preßpapier u. dgl., vorgesehen sind, so daß eine Funken erzeugende Berührung von Metallflächien vermieden ist.This deficiency is alleviated by the invention turn remedied. It does this because in the places where as a result the pendulum of the grinding ring pushes it against the housing, deposits from a non-sparking one Substances, e.g. B. Pockholz, press paper and the like. Are provided, so that a spark producing contact with metal surfaces is avoided.

In idetr Zeiohnung ist die Erfindung in einem Aiusführungsbeispdel dargestellt.In other words, the invention is in shown in a guide example.

Abb. ι zeigt einen Längsschnitt und Abb. 2 einen Querschnitt einer Ringwalzenmühle.Fig. Ι shows a longitudinal section and Fig. 2 shows a cross section of a ring roller mill.

Der Mahlring 2 besitzt an seiner Außenkante S eine Einlage aus nichtfunkendem Stoff, so daß bei einem seitlichen Pendeln und einer Red-bung an den Schleißleiisten 4 des Mahlgahäuses 1 keine Funken entstehen können. Man kann auch an Stelle des in den Miahlringen eingesetzten Schlaißringes die Schleißleisten selbst aus nichtfunkendem Stoff herstellen. Mit 3 sind die üblichen Mahlwalzen bezeichnet.The grinding ring 2 has a non-sparking insert on its outer edge S Fabric, so that with a sideways swing and a red exercise on the wear strips 4 of the Mahlgahäuses 1 no sparks can arise. You can also use the Miahlringen used hose ring, the wear strips themselves from non-sparking Making fabric. With 3 the usual grinding rollers are designated.
