Die Trenneinrichtung 9 wird beispielsweise durch einen beschaufelten Rotorkörper 12 gebildet, der sich zusammen mit dem Rotor 8 dreht, und so gestaltet und betrieben, dass sie bzw. er Mahlkörper 6 nicht durchlassen soll, indem die Trenneinrichtung 9 insbesondere durch die Größe der Zwischenräume zwischen den Schaufeln 13 des beschaufelten Rotorkörpers 12 sowie die Drehbewegung des beschaufelten Rotorkörpers 12 die Mahlkörper 6 abweist und damit am Durchgang durch die Trenneinrichtung 9 aus dem Mahlraum 3 in den Produktauslass 11 hindert. Während bei Normalbetrieb der Mühle schon die Rotation der Trenneinrichtung 9 dafür sorgt, dass Mahlkörper 6 zuverlässig überwiegend daran gehindert werden, die Trenneinrichtung 9 zu durchqueren und die Mahlkörpermühle 1 bzw. deren Mahlraum 3 durch den Produktauslass 11 zu verlassen, kommt es besonders in Abbremsphasen des Rotors 8 dazu, dass vereinzelt Mahlkörper 6 infolge der geringeren Drehgeschwindigkeit des Rotors 8 und damit des beschaufelten Rotorkörpers 12 der Trenneinrichtung 9 durch letztere aus dem Mahlraum 3 in den Produktauslass 11 gelangen. Dies kann aber auch im Normalbetrieb erfolgen, wenn die Abmessungen von Mahlkörpern 6 verschleißbedingt abgenommen haben.The separating device 9 is formed, for example, by a
Solche aus dem Mahlraum 3 entkommene Mahlkörper müssen einerseits gesondert aus dem fertig gemahlenen Mahlgut 10 entfernt werden, und zwar möglichst ohne einen kontinuierlichen Mahlgutstrom zu behindern. Um trotz dadurch auftretender Mahlkörperverluste die Füllung des Mahlraums 3 mit Mahlkörper auf einer vorgegebenen Menge zu halten, müssen andererseits auch immer wieder Mahlkörper nachgefüllt werden, wozu aufwendige Bestimmungen und Überwachungen der entsprechenden Mahlkörperfüllmenge erforderlich sind. Dies alles bereitet zusätzlichen Aufwand beim Betrieb einer Mahlkörpermühle.On the one hand, such grinding media escaping from the grinding

Das erste Ausführungsbeispiel einer Mahlkörpermühle 1 gemäß der
Die Trenneinrichtung 9 wird bei einer solchen Rührwerkskugelmühle 1 beispielsweise durch den beschaufelten Rotorkörper 12 gebildet, der sich zusammen mit dem Rotor 8 dreht, und so gestaltet und betrieben, dass sie bzw. er Mahlkörper 6 nicht durchlassen soll, indem die Trenneinrichtung 9 insbesondere durch die Größe der Zwischenräume zwischen den Schaufeln 13 des beschaufelten Rotorkörpers 12 sowie die Drehbewegung des beschaufelten Rotorkörpers 12 die Mahlkörper 6 abweist und damit am Durchgang durch die Trenneinrichtung 9 aus dem Mahlraum 3 in den Produktauslass 11 hindert. Während bei Normalbetrieb der Mühle schon die Rotation der Trenneinrichtung 9 dafür sorgt, dass Mahlkörper 6 zuverlässig überwiegend daran gehindert werden, die Trenneinrichtung 9 zu durchqueren und die Mahlkörpermühle 1 bzw. deren Mahlraum 3 durch den Produktauslass 11 zu verlassen, kommt es besonders in Abbremsphasen des Rotors 8 dazu, dass vereinzelt Mahlkörper 6 infolge der geringeren Drehgeschwindigkeit des Rotors 8 und damit des beschaufelten Rotorkörpers 12 der Trenneinrichtung 9 durch letztere aus dem Mahlraum 3 in den Produktauslass 11 gelangen. Dies kann aber auch im Normalbetrieb erfolgen, wenn die Abmessungen von Mahlkörpern 6 verschleißbedingt abgenommen haben.The separator 9 is formed in such a stirred ball mill 1, for example, by the
Solche aus dem Mahlraum 3 entkommene Mahlkörper müssen bei Mahlkörpermühlen 1 nach dem Stand der Technik einerseits gesondert aus dem fertig gemahlenen Mahlgut 10 entfernt werden, und zwar möglichst ohne einen kontinuierlichen Mahlgutstrom zu behindern. Um trotz dadurch auftretender Mahlkörperverluste die Füllung des Mahlraums 3 mit Mahlkörper auf einer vorgegebenen Menge zu halten, müssen andererseits auch immer wieder Mahlkörper nachgefüllt werden, wozu aufwendige Bestimmungen und Überwachungen der entsprechenden Mahlkörperfüllmenge erforderlich sind.

Hier schafft die vorliegende Erfindung Abhilfe, indem dem Produktauslass 11 ein Austragsstutzen 14 nachgeschaltet ist, der gegenüber der Horizontalen geneigt ist. Diese Neigung des Austragsstutzens 14 ist bei der Mahlkörpermühle 1 des ersten Ausführungsbeispiels gemäß der

Bei der Gestaltung des ersten Ausführungsbeispiels der der Mahlkörpermühle 1 mit dem aufwärts geneigten Austragsstutzen 14 ist von besonderem Vorteil, dass ohne weitere Einrichtungen und Maßnahmen alleine durch Ausnutzung der Schwerkraft innerhalb des aufwärts geneigten Austragsstutzens 14, jedenfalls dann, wenn die Transportströmung durch den Produktauslass 11 beim Abschalten der Mahlkörpermühle 1 geringer wird und schließlich wegfällt, die fälschlicherweise aus dem Mahlraum 3 durch den Produktauslass 11 in den Austragsstutzen 14 entkommenen Mahlkörper 6 automatisch durch den Produktauslass 11 in die Trenneinrichtung 9 zurückrutschen oder -rollen. Jedenfalls beim Wiederanfahren der Mahlkörpermühle 1 werden dann, jedenfalls solange noch keine ausreichend starke Strömung mit fertig gemahlenem Mahlgut 10 durch die Trenneinrichtung 9 und weiter durch den Produktauslass 11 besteht, die in der Trenneinrichtung 9 gesammelten Mahlkörper 6 durch die Drehbewegung der Trenneinrichtung 9 wieder in den Mahlraum 3 zurückbefördert oder -geschleudert. Bei dieser Ausführung treten die zurückgeführten Mahlkörper 6 also wieder am Austragsende, d.h. im Bereich des Produktauslasses 11, in den Mahlraum 3 ein und werden so zum Mahlprozess zurückgeführt und nehmen ab da wieder am Mahlprozess teil.In the design of the first embodiment of the grinding mill 1 with the upwardly
Auf weitere Einzelheiten von Mahlkörpermühlen und insbesondere Rührwerkskugelmühlen im Zusammenhang mit dem Mahlvorgang wird hier nicht weiter eingegangen, da davon ausgegangen wird, dass diese Einzelheiten für verschiedene Gestaltungen und Betriebsvarianten dem Fachmann bekannt sind, und da solche die Mahlung betreffenden Einzelheiten zur vorliegenden Erfindung nicht beitragen.Further details of grinding media mills and in particular agitator ball mills in connection with the grinding process will not be discussed here, since it is assumed that these details are known to the person skilled in the art for various designs and operating variants, and since such details concerning the grinding do not contribute to the present invention.
