Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die auf beiliegenden Zeichnungen durch die Fig. i, 2 und 3 dargestellte Kugelfallmühle ist gekennzeichnet durch die auf den Stirnseiten im Innern der Mahltrommel in radialer Richtung laufenden Rippen A von dreieckigem oder trapezförmigem Querschnitt. Die Rippen nehmen von der Trommelachse nach dem Trommelmantel hin an Breite und Höhe zu, wie aus Fig. ι und 2 ersichtlich ist. Die Abwickelung Fig. 3. zeigt die Rippen im Querschnitt, der beispielsweise trapezförmig angenommen ist.The ball mill shown in the accompanying drawings by FIGS. 1, 2 and 3 is characterized by the ribs A of triangular or trapezoidal cross-section running in the radial direction on the end faces in the interior of the grinding drum. The ribs increase in width and height from the drum axis towards the drum shell, as can be seen from FIGS. The development in FIG. 3 shows the ribs in cross section, which is assumed to be trapezoidal, for example.

Beim Rotiren der in den beiden Zapfen B gelagerten Trommel werden die in der Trommel befindlichen Kugeln oder Steine mit dem dazwischen liegenden zu mahlenden Material jedesmal durch die Rippen nach der Mitte hin zusammengeschoben und schnellen alsdann wieder aus einander, wodurch die Mahlwirkung erhöht wird. Auch wird der Trommelinhalt höher gehoben, infolge dessen eine gröfsere Mahlfläche erreicht wird.When the drum mounted in the two pins B rotates, the balls or stones in the drum with the material to be ground in between are each time pushed together by the ribs towards the center and then snap apart again, whereby the grinding effect is increased. The contents of the drum are also raised higher, as a result of which a larger grinding surface is achieved.
