Die Trennung von Substanzen, deren specifische Gewichte nur geringe Unterschiede zeigen, bietet mitunter trotz verschiedenartigen Aggregatzustandes und verschiedenartiger Krystallform grofse Schwierigkeiten.The separation of substances, the specific gravity of which shows only slight differences, sometimes offers despite different aggregate states and different crystal forms great difficulties.
Ist aber durch bestimmte äufsere oder chemische Einflüsse es möglich, auf die eine der zu trennenden Substanzen in höherem Grade als auf die andere einzuwirken, dafs ihre Zerreiblichkeit' eine, höhere wird, oder besteht bei den betreffenden Substanzen an sich ein hinreichender Cohäsionsunterschied, so fehlt es wiederum an einer Vorrichtung, die auf eine mechanisch continuirliche Weise es gestattet, dergleichen Substanzen in Körnerform vermöge ihrer neuen Eigenschaftsunterschiede leicht und sicher zu trennen.But is it possible, through certain external or chemical influences, to approach one of the separating substances to a greater degree than on the other, so that their friability ' one, becomes higher, or there is in itself a sufficient one for the substances in question Cohesion difference, there is again a lack of a device that relies on a mechanical In a continuous way it allows such substances in granular form by virtue of their new ones Separate property differences easily and safely.
Diese Lücke soll der auf beiliegender Zeichnung dargestellte und durch Nachstehendes erläuterte Mahlapparat ausfüllen.This gap is intended to be the one shown in the accompanying drawing and explained by the following Fill out the grinding apparatus.
Derselbe besteht im wesentlichen aus einer aufgeränderten, nach dem Centrum zugeneigten runden Schale a, welche im Centrum eine Abflufsöffnung hat. Diese Schale hat eine auswechselbare Hartgufseinlage, ist äufserlich mit einem Zahnkranz versehen, in welchen ein Getriebe eingreift, und rotirt vermittelst Rollen auf einer .kreisrunden Schienenbahn. It consists essentially of a round bowl a, which is rimmed up and inclined towards the center, and which has a drainage opening in the center. This shell has an exchangeable hard cast iron insert, is externally provided with a toothed ring, in which a gear engages, and rotates by means of rollers on a circular rail track.
Eine durch die im Centrum befindliche Abflufsöfifnung hindurchreichende stehende Welle b trägt eine an derselben mittelst Stellringe höher oder tiefer zu stellende Scheibe c mit zahlreichen Löchern. In diese Löcher werden .Stahlbolzen stehend eingestellt, so dafs sie sich frei auf- und niederbewegen können, und üben durch ihr Eigengewicht einen Druck auf die Hartgufsschale d aus. A standing wave b , which extends through the drainage opening in the center, carries a disk c with numerous holes, which can be raised or lowered by means of adjusting rings. Steel bolts are set upright in these holes, so that they can move freely up and down, and exert a pressure on the hard-cast iron shell d by their own weight.
Der Scheibe c mit ihrem Stahlbolzen, wird eine raschere Drehung gegeben als der Schale a, und zwar in entgegengesetztem Sinne. An der Peripherie der letzteren sind feststehende Aufgabegefäfse e angebracht, welche die zu trennenden Substanzen regenartig auf die Schalenwand abfliefsen lassen, wonach sie von den Stahlbolzen gefafst, um je nach dem Grade der Widerstandsfähigkeit mehr oder weniger zerrieben zu werden. <The disk c with its steel pin is given a faster rotation than the shell a, in the opposite sense. At the periphery of the latter fixed Aufgabegefäfse e are attached which the blank abfliefsen substances to be separated rain-like manner on the shell wall, after which it gefafst of the steel bolt to be ground according to the degree of resistance more or less. <
Das so durch die .Stahlbolzen passirte Gut wird durch die Mitte der Schale vermittelst einer Lutte der Separationstrommel f zugeführt, in welcher die Trennung der Substanz durch Konigröfsendifferenz auf einfache Weise erzielt wird.The material thus passed through the steel bolts is fed through the center of the bowl by means of a duct to the separation drum f , in which the separation of the substance is achieved in a simple manner by the difference in the cone size.
