Es wird eine Vorrichtung zum Starten einer Rührwerkskugelmühle beschrieben, wobei die Rührwerkskugelmühle einen senkrecht stehenden Mahlbehälter besitzt. In dem Mahlbehälter ist eine senkrecht verlaufende Rührwelle angeordnet, auf der mindestens ein Mahlelement angeordnet ist. Der Mahlbehälter ist zum Großteil mit Mahlhilfskörpern gefüllt.The present invention relates to an apparatus and a method for starting stirred ball mills.

In the grinding container, a vertically extending stirring shaft is arranged, on which at least one refining element is arranged. The grinding container is largely filled with Mahlhilfskörpern.
In der Offenlegungsschrift
Die in der
Die Erfindung der
Allen vorab genannten Druckschriften ist gemein, dass sie senkrecht stehende Rührwerkskugelmühlen beschreiben, in deren Mahlbehälter im unteren Bereich eine große Menge von Mahlhilfskörpern angeordnet ist. Da die Mahlhilfskörper im Allgemeinen eine sehr hohe Dichte besitzen, ist die Mahlhilfskörperpackung relativ schwer. Durch dieses relativ hohe Gewicht wird das Anlaufen bzw. das Anfahren der beschriebenen Rührwerkskugelmühlen deutlich erschwert. Gemäß dem Stand der Technik wird dieses Problem in aller Regel durch eine Überdimensionierung des Antriebsmotors gelöst. Durch diesen stark vergrößerten Antrieb entstehen für die Herstellung der Mühle deutlich erhöhte Kosten und auch der bei der Produktion benötigte Energiebedarf ist deutlich höher als bei beispielsweise liegenden Rührwerkskugelmühlen.
Die obige Aufgabe wird durch eine Rührwerkskugelmühle gelöst, die die Merkmale des Anspruchs 1 umfasst. Weitere vorteilhafte Merkmale sind den Unteransprüchen zu entnehmen.The above object is achieved by an agitator ball mill comprising the features of claim 1. Further advantageous features can be found in the dependent claims.
Weiterhin liegt der Erfindung die Aufgabe zugrunde ein Verfahren zum ökonomischen und betriebssicheren Starten einer stehenden Rührwerkskugelmühle bereit zu stellen.Another object of the present invention is to provide a method for economically and reliably starting a stationary stirred ball mill.
Die obige Aufgabe wird durch ein Verfahren gelöst, das die Merkmale des Anspruchs 7 umfasst. Weitere vorteilhafte Merkmale sind den Unteransprüchen zu entnehmen.The above object is achieved by a method comprising the features of claim 7. Further advantageous features can be found in the dependent claims.
Es wird eine Vorrichtung zum Starten einer Rührwerkskugelmühle beschrieben, wobei die Rührwerkskugelmühle einen senkrecht stehenden Mahlbehälter besitzt. In dem Mahlbehälter ist eine senkrecht verlaufende Rührwelle angeordnet, auf welcher mindestens ein Mahlelement angeordnet ist. Der Mahlbehälter ist zum Großteil mit Mahlhilfskörpern gefüllt. Die Rührwelle ist beim Start der Rührwerkskugelmühle durch die erfindungsgemäße Vorrichtung zum Starten anhebbar. Hierbei ist es von großem Vorteil, dass nur die Rührwelle mit den sich darauf befindenden Mahlelementen angehoben wird. Der Antrieb der Rührwerkskugelmühle bleibt an seiner Position. Die Rührwelle ist hierzu in einer Buchse gelagert und ist durch die Drehbewegung dieser Buchse anhebbar. Die Buchse ist mit dem Antrieb der Rührwerkskugelmühle verbunden und wird durch diesen entsprechend rotatorisch bewegt. Weiterhin ist die Buchse mit mindestens einer Aussparung versehen, in der mindestens ein Bolzen, der mit der Rührwelle verbunden ist, beweglich geführt ist. Die in der Buchse befindliche Aussparung weist eine Steigung auf. Je größer die Steigung der Aussparung ist, desto größer ist der axiale Weg, den der Bolzen bei der Drehbewegung zurücklegen muss. Mit der Größe der Steigung nimmt jedoch die Axialkraft zum Heben der Rührwelle ab. Bei einer flachen Steigung verhält es sich genau umgekehrt. Der Weg, um den die Rührwelle angehoben wird, ist geringer und die Axialkraft zum Heben der Rührwelle, an welcher sich die Mahlelemente befinden, nimmt entsprechend zu.An apparatus for starting an agitator ball mill is described, wherein the agitator ball mill has a vertical grinding container. In the grinding container, a vertically extending stirring shaft is arranged, on which at least one refining element is arranged. The grinding container is mostly with Mahlhilfskörpern filled. The stirrer shaft can be raised by the device according to the invention for starting when the agitator ball mill is started. Here, it is of great advantage that only the stirring shaft is lifted with the grinding elements located thereon. The drive of the agitator ball mill remains in its position. The stirring shaft is mounted for this purpose in a socket and can be raised by the rotational movement of this socket. The bush is connected to the drive of the agitator ball mill and is moved by this corresponding rotational. Furthermore, the bush is provided with at least one recess in which at least one bolt, which is connected to the agitator shaft, is movably guided. The recess located in the socket has a slope. The larger the pitch of the recess, the greater is the axial distance that the bolt must travel during the rotary motion. However, as the pitch increases, the axial force to lift the agitator shaft decreases. With a flat slope, the situation is exactly the opposite. The distance by which the agitator shaft is raised is lower, and the axial force for lifting the agitator shaft at which the grinding elements are located increases accordingly.
In einer weiteren Ausführungsform ist es möglich, dass die Aussparung sowohl eine Steigung als auch ein Gefälle aufweist. Bei dieser Ausführungsform wird während der Drehbewegung der Bolzen und mit ihm die verbundene Rührwelle kurz angehoben und kurz darauf im Bereich des Gefälles wieder abgesenkt. Um den Bolzen wieder in seine Ausgangsposition zurückzubewegen, muss in dieser Ausführungsform die Rührwerkskugelmühle rückwärts betrieben / gefahren werden. Im Normalbetrieb befindet sich die Rührwelle mit den Mahlelementen immer in der unteren Position (Ausgangsposition). Die Rührwelle wird während des Startens angehoben und im weiteren Verlauf wieder abgesenkt, was dem normalen Betriebszustand entspricht. Bei einem darauffolgenden Start der Mühle muss diese in die entgegengesetzte Drehrichtung eingeschaltet werden. Die Drehrichtung der Rührwelle ist somit abhängig von der Position des Bolzens in der Ausnehmung der Buchse. Die Drehrichtung muss so gewählt werden, dass der Bolzen während des Starts in die jeweils andere Endlage geführt wird.In a further embodiment, it is possible that the recess has both a slope and a slope. In this embodiment, during the rotary movement of the bolt and with him the associated agitator shaft is briefly raised and shortly thereafter lowered in the region of the gradient again. In order to move the bolt back to its starting position, the agitator ball mill must be operated / moved backwards in this embodiment. In normal operation, the stirring shaft with the grinding elements is always in the lower position (starting position). The stirrer shaft is lifted during startup and then lowered again, which corresponds to the normal operating condition. On a subsequent start of the mill, it must be switched on in the opposite direction of rotation. The direction of rotation of the stirring shaft is thus dependent on the position of the bolt in the recess of the socket. The direction of rotation must be selected so that the bolt is guided into the other end position during the start.
In der ersten beschriebenen Ausführungsform können die Rührwelle und die Mahlelemente durch das Anhalten der Rührwerkskugelmühle allein, durch die Gewichtskraft der Rührwelle, der Mahlelemente, der auf den Mahlelementen liegenden Mahlhilfskörpern in eine Ausgangsposition zurückgedreht und somit in Ausgangsposition abgesenkt werden. In dieser Ausführungsform ist es auch denkbar, dass die Mühle nach dem Ausschalten kurz in die entgegengesetzte Drehrichtung eingeschaltet wird, um das Absenken der Rührwelle mit den Mahlelementen aktiv zu unterstützen.In the first described embodiment, the stirrer shaft and the grinding elements can be stopped by stopping the agitating ball mill alone, by the weight force of the stirring shaft, the grinding elements lying on the grinding elements Mahlhilfskörpern turned back to a starting position and thus lowered to the starting position. In this embodiment, it is also conceivable that the mill is switched shortly after switching off in the opposite direction of rotation to actively support the lowering of the stirring shaft with the grinding elements.
In der Buchse kann eine Rückhaltevorrichtung vorhanden sein, die den Anschlag des Bolzens an einer Endposition abbremst. Die Rückhaltevorrichtung kann eine Feder, ein Dämpfer oder ein ähnliches Bauteil sein. Weiterhin ist es auch möglich, mit der Rückhaltevorrichtung das Absenken der Rührwelle und somit die Rückführung in die Ausgangsposition zu unterstützen. Für den Fachmann ist klar, dass es eine Vielzahl von Möglichkeiten und Rückhaltevorrichtungen gibt, um den Anschlag des Bolzens zu verringern. Daher stellt die vorab gemachte Aufzählung keine Einschränkung der Erfindung dar.In the socket, a retaining device may be present, which decelerates the stop of the bolt at an end position. The retaining device may be a spring, a damper or a similar component. Furthermore, it is also possible to support with the retaining device, the lowering of the stirring shaft and thus the return to the starting position. It will be apparent to those skilled in the art that there are a variety of ways and retainers to reduce the impact of the bolt. Therefore, the list made in advance does not limit the invention.
Weiterhin wird ein Verfahren zum Starten einer Rührwerkskugelmühle beschrieben, bei welchem die Rührwelle mit den Mahlelementen durch eine Drehbewegung angehoben wird. Die Drehbewegung wird durch eine Buchse realisiert, wobei durch die Drehbewegung der Buchse ein Bolzen angehoben wird, der in einer Aussparung angeordnet und mit der Rührwelle fest verbunden ist. Der Bolzen und mit ihm die Rührwelle wird um den Weg angehoben, der einer Steigung der Aussparung der Buchse entspricht.Furthermore, a method for starting a stirred ball mill is described in which the stirring shaft is lifted with the grinding elements by a rotary motion. The rotational movement is realized by a socket, wherein a bolt is raised by the rotational movement of the bush, which is arranged in a recess and fixedly connected to the agitator shaft. The bolt and with it the stirrer shaft is raised by the path corresponding to a pitch of the recess of the bushing.
