Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntlich muß bei der Bearbeitung von Rohschmirgel, und zwar sowohl des natürlichen als auch des künstlichen, das Gut in mehreren Arbeitsgängen bis zu einer ganz feinen und gleichmäßigen Körnung zerkleinert werden. Diese Arbeit zerfällt in zwei aufeinanderfolgende Arbeitsperioden, nämlich die grobe Bearbeitung oder Vorbrechung in Backenbrechern, Kollergängen oder ähnlichen Vorrichtungen, und weiterhin die feinere Vermahlung zwischen Walzen. In beiden Fällen entsteht eine erhebliche Schwierigkeit durch die außerordentliche Härte und Widerstandsfähigkeit des Gutes. Es war bisher üblich.^die Arbeitsflächen der Mahlkörper für diesen Zweck aus Hartguß oder aus Stahl herzustellen. Diese Flächen unterliegen einem außerordentlich hohen und raschen Verschleiß, und besonders die Walzen der Mahlgänge für die feine Körnung werden derartig beansprucht, daß sie ihre glatte Fläche verlieren und unrund werden. Außer der Zerstörung der Walzen haben diese Vorgänge noch den Mißstand im Gefolge, daß die abgescherten Stahlteilchen in das Mahlgut gelangen und das fertige Fabrikat in unangenehmer Weise verunreinigen.It is well known that when processing raw emery, both natural as well as the artificial, the material is crushed in several operations to a very fine and even grain will. This work is divided into two consecutive work periods, namely the rough machining or pre-breaking in jaw crushers, pan mills or similar devices, and furthermore the finer grinding between rollers. In both cases a considerable difficulty arises from the extraordinary Hardness and resilience of the goods. It was customary up to now. ^ The work surfaces to manufacture the grinding media for this purpose from chilled cast iron or steel. These areas are subject to an extraordinary high and rapid wear, and especially the rollers of the grinding passages for the fine grain size are so stressed that they lose their smooth surface and become out of round. In addition to the destruction of the rollers, these processes also have the consequence that the sheared steel particles get into the grist and the finished product in unpleasant Pollute way.
Gegenstand der Erfindung ist eine Vorrichtung zur Zerkleinerung von Rohschmirgel, durch welche diese Mißstände beseitigt oder zum mindesten erheblich herabgesetzt werden. Demgemäß besteht der Gegenstand der Erfindung darin, daß die Mahlkörper, d. h. sowohl die Brechbacken der Steinbrecher, die Walzenringe für die Kollergangläufer und die Bodenplatten für die Kollergänge als auch die Walzen für die feine Verarbeitung aus hart gebrannter Schmirgelmasse hergestellt sind. Hierdurch wird der doppelte Vorteil erreicht, daß einerseits die Lebensdauer der Walzen infolge ihrer größeren Widerstandsfähigkeit verlängert, andererseits etwa doch abgescherte Teilchen der Walzenfläche, wenn sie in das Mahlgut gelangen, dieses nicht verunreinigen, da sie aus dem gleichen Grundstoff bestehen wie das Mahlgut selber.The invention relates to a device for comminuting raw emery, through which these abuses are eliminated or at least considerably reduced. Accordingly, the object of the invention is that the grinding media, i. H. as well as the crushing jaws of the stone crusher, the roller rings for the pan mill runners and the Floor plates for the pan mills as well as the rollers for fine processing hard-fired emery compound are made. This will have the double benefit achieves that on the one hand the life of the rollers due to their greater resistance extended, on the other hand any sheared-off particles of the roller surface, if they get into the grinding stock, do not contaminate it, because they consist of the same raw material as the grist itself.
Bei den zur feineren Vermahlung des Rohschmirgels üblichen Walzenstühlen kann noch die Anordnung getroffen werden, daß die Zerkleinerungswalzen aus aneinandergereihten, hartgebrannten Scheiben oder Ringen aus Schmirgelmasse zusammengesetzt werden.In the case of the roller mills customary for finer grinding of the raw emery, it is still possible the arrangement can be made that the shredding rollers are made of strung together, hard-burned disks or rings are assembled from emery compound.
