Kugelmühle mit aus Mahlbalken hergestellter Mahibahn,Ball mill with a Mahibahn made from grinding bars,

Patentiert im Deutschen Reiche vom 20. März 1923 ab.Patented in the German Empire on March 20, 1923.

Die Erfindung bezieht sich besonders auf langsam laufende Kugelmühlen, in denen die Gesamtmenge der Kugeln zusammen mit dem Gut als eine einzige Masse ständig an der Wandung nach unten rutscht und so im Gegensatz zu den Kugelfallmühlen ein Zerreiben des Gutes bewirkt.The invention particularly relates to slow running ball mills in which the Total amount of balls together with the goods as a single mass constantly at the Wall slips downwards and so, in contrast to the ball drop mills, grinding of the good causes.

Zur Erhöhung der Leistung der Kugelmühle hat es sich; als sehr vorteilhaft herausgestellt, die einzelnen Mahlbalken so auszuführen, daß eine wellenförmige Mahlbahn gebildet wird. Bei Verwendung von Mahlbalken aus gleich hartem Material nimmt aber erfahrungsgemäß die Wellenform infolge Verschleißes immer mehr ab; dadurch wird auch die Leistungsfähigkeit der Kugelmühle allmählich vermindert.To increase the performance of the ball mill, it has been found; turned out to be very advantageous, to design the individual grinding bars in such a way that a wave-shaped grinding path is formed will. However, experience has shown that when using grinding bars made of the same hard material the waveform decreases more and more as a result of wear; this also gradually increases the performance of the ball mill reduced.

Durch die vorliegende Erfindung sollen diese Übelstände beseitigt werden.The present invention aims to remedy these inconveniences.

Das Wesen der Erfindung besteht darin,The essence of the invention is

naß Mahlbalkeri von verschiedener Härte verwendet sind.Wet Mahlbalkeri of various hardness are used.

In der Zeichnung ist ein Teil des Mahlmantels dargestellt: α ist der äußere Trommelmantel, während b die harten und c die weniger harten Mahlbalken bedeuten, d sind Aussparungen der Mahlbalken und e Holzkeile, durch welche die Mahlbalken in der Trommel befestigt werden.In the drawing, a part of the grinding jacket is shown: α is the outer drum jacket, while b denotes the hard and c the less hard grinding bars, d are recesses in the grinding bars and e wooden wedges through which the grinding bars are fixed in the drum.

Die Mühle dreht sich in Pfeilrichtung. Die obere Fläche der Mahlbalken wird so ausgeführt, daß eine wellenförmige Mahlbahn entsteht. Die Wellenform wird bei Verwendung von verschiedener Härte auch im späteren Betriebe vollkommen bestehen bleiben, weil sich die härteren Mahlbalken nicht so schnell abnutzen als die weniger harten.The mill rotates in the direction of the arrow. The upper surface of the grinding bars is designed in such a way that that a wave-shaped grinding path is created. The waveform will also be used later when different hardnesses are used Establishments remain completely in place because the harder grinding bars do not move as quickly wear out than the less hard ones.
