Description
Rührwerkskugelmühle mit einem eine Rührwelle umgebenden Mahlbehälter, der mit einem Produkteinlaß und einem Produktauslaß versehen ist, wobei die innerhalb des Mahlbehälters befindlichen Mahlhilfskörper durch die Rotation der Rührwelle aktiviert und von einer Trenn- oder Klassiereinrichtung im Mahlraum zurückgehalten werden.Agitator ball mill with a mixing vessel surrounding a stirring shaft, which is provided with a product inlet and a product outlet, wherein the Mahlhilfskörper located within the grinding container are activated by the rotation of the stirring shaft and retained by a separating or classifying device in the grinding chamber.

Ziel der Erfindung ist es eine Mahl- und Dispergiervorrichtung mit einer Vorzerkleinerung zu kombinieren, die weitestgehend gegen den Verschleiß geschützt ist, den das Mahlgut-/Mahlhilfskörpergemisch verursachen kann.The aim of the invention is to combine a grinding and dispersing with a pre-crushing, which is largely protected against the wear that can cause the Mahlgut- / Mahlhilfskörpergemisch.
Das Ziel wird mit einer Rührwerkskugelmühle erreicht, bei der nach dem Produkteinlaß eine Vorzerkleinerungseinrichtung vorgesehen ist, die zum Mahlraum einen Spaltschutz aufweist.The goal is achieved with a stirred ball mill, in which after the product inlet a pre-shredding device is provided, which has a gap protection to the grinding chamber.
Aufgrund des im Mahlbehälter herrschenden Drucks und der prozentualen hohen Mahlhilfskörperfüllung im Mahlbehälter können, während des Betriebs der Rührwerkskugelmühle, Mahlhilfskörper an den Spalt der Vorzerkleinerungseinrichtung gelangen und hier zu Verschleiß oder anderen Beeinträchtigungen führen. Aufgrund dessen ist es in einer vorteilhaften Ausgestaltung der Erfindung vorgesehen den Spalt entweder durch einen dynamischen oder statischen Spaltschutz zu schützen.Due to the pressure prevailing in the grinding container and the percentage high Mahlhilfskörperfüllung in the grinding container, during the operation of the ball mill, Mahlhilfskörper reach the gap of Vorzerkleinerungseinrichtung and here lead to wear or other adverse effects. Because of this, it is provided in an advantageous embodiment of the invention to protect the gap either by a dynamic or static gap protection.
Unter bestimmten Bedingungen im Mahlraum kann es vorteilhaft sein, den Spaltschutz als rotierendes oder statisches Teil nach dem Vorzerkleinerer anzuordnen.Under certain conditions in the grinding chamber, it may be advantageous to arrange the gap protection as a rotating or static part after the pre-shredder.
Die Wirkung des Spaltschutzes wird entsprechend der Erfindung dadurch verbessert, daß hierbei ein Ringelement zur Anwendung kommt, das mit dem Rotor des Vorzerkleinerers verbunden ist. Hierbei schleudert das Ringelement die Mahlhilfskörper im Bereich des Spalts radial ab und erzeugt gleichzeitig eine Unterdruckzone am Ende des Spaltübergangs zum Mahlraum wodurch das Produkt aus der Vermahlzone leicht in den Mahlraum übertritt.The effect of the gap protection is improved according to the invention in that in this case a ring element is used, which is connected to the rotor of the pre-shredder. Here, the ring element hurls the Mahlhilfskörper radially in the region of the gap and simultaneously generates a negative pressure zone at the end of the gap transition to the grinding chamber whereby the product easily passes from the grinding zone into the grinding chamber.
In einer erfindungsgemäßen Ausgestaltung der Erfindung weist das Ringelement am mahlraumseitigen Ende des Mahlspalts einen Ansatz auf, der keil- bzw. nasenförmig gestaltet sein kann.In one embodiment of the invention, the ring element on the grinding chamber-side end of the grinding gap on a neck, which may be designed wedge-shaped or nose-shaped.
Diese Gestaltung bringt den Vorteil mit sich, daß zwischen dem Ansatz und dem Ringelement ein Abstand eingehalten werden kann, der dem 2- bis 10-fachen der Weite des Mahlspalts entspricht. Dieser Abstand kann bei aufwendiger Konstruktion der Befestigung des Ringelements, der Größe des vorzerkleinerten Gutes oder den Mahlhilfskörpern angepaßt werden.This design has the advantage that between the approach and the ring member, a distance can be maintained, which corresponds to 2 to 10 times the width of the grinding gap. This distance can be adapted in case of complicated construction of the attachment of the ring element, the size of the pre-shredded material or grinding auxiliary bodies.
Entsprechend einer weiteren Ausgestaltung der Erfindung kann es für die Funktion der Vorzerkleinerungsvorrichtung wesentlich sein, daß das statische oder dynamische Ringelement nicht nur radial am Mahlspalt endet, sondern diesen überlappt und zwar in einem Verhältnis vom 2- bis 10-fachen der Weite des Mahlspalts.According to a further embodiment of the invention, it may be essential for the function of the pre-shredding device that the static or dynamic ring element not only ends radially at the grinding gap, but overlaps it in a ratio of 2 to 10 times the width of the grinding gap.
Entsprechend einer bevorzugten Ausführung besteht die Vorzerkleinerungseinrichtung aus einem rotierenden Teil und einem stehenden Teil, wobei das rotierende Teil wiederum vorzugsweise mit der Rührwelle in Verbindung steht.According to a preferred embodiment, the pre-shredding device consists of a rotating part and a stationary part, wherein the rotating part in turn is preferably in communication with the stirring shaft.
Das stehende Teil der Vorzerkleinerungseinrichtung steht mit dem Mahlbehälter in Verbindung. Dies ist insbesondere dann von Vorteil, wenn dieser Bereich des Mahlbehälters gekühlt wird. Schon die Kühlung eines der Teile der Vorzerkleinerungseinrichtung bewirkt das Konstanthalten der Produkttemperatur während der Vorzerkleinerung.The stationary part of the pre-shredding device communicates with the grinding container. This is particularly advantageous when this area of the grinding container is cooled. Even the cooling of one of the parts of the pre-shredding device keeps the product temperature constant during the pre-shredding.
Bei einer vorteilhaften Weiterbildung der Erfindung sind die Zahnscheiben so angeordnet, daß deren zum Mahlraum gerichtete Flächen des rotierenden und des stehenden Teils der Vorzerkleinerungseinrichtung gleichzeitig die einlaßseitige Mahlraumbegrenzung bilden.In an advantageous embodiment of the invention, the toothed disks are arranged so that their faces directed towards the grinding chamber surfaces of the rotating and the stationary part of the pre-shredding simultaneously form the inlet-side Mahlraumbegrenzung.
Der vom stehenden und vom rotierenden Teil der Vorzerkleinerungseinrichtung gebildete Spalt wird vorteilhafterweise kleiner gehalten als der Durchmesser der im Mahlraum befindlichen Mahlhilfskörper. Dabei wird eine Spaltweite von 0,2 - 2 mm gewählt. Durch die Anordnung von zusätzlichen Flügeln oder dergleichen auf der zum Mahlraum weisenden Seite des rotierenden Teils kann die Einströmung der vorzerkleinerten Produktteile verbessert und ein Mahlhilfskörperstau im Bereich des Scherspaltes vermieden bzw. reduziert werden.The gap formed by the stationary and the rotating part of the pre-shredding device is advantageously kept smaller than the diameter of the grinding auxiliary body located in the grinding chamber. In this case, a gap width of 0.2 - 2 mm is selected. By the arrangement of additional wings or the like on the zum Mahlraum pointing side of the rotating part, the inflow of pre-shredded product parts can be improved and a Mahlhilfskörperstau be avoided or reduced in the shear gap.
In einer besonderen erfindungsgemäßen Ausgestaltung kann entweder das rotierende oder auch das stehende Teil der Vorzerkleinerungseinrichtung axial verstellbar sein, wodurch die Spaltweite während, vor oder nach dem Produktionsprozeß verändert werden kann. In einer rein mechanischen Ausgestaltungsmöglichkeit der Erfindung sind sowohl das rotierende wie auch das stehende Teil der Vorzerkleinerungseinrichtung über Gewinde auf der Rührwelle oder am Mahlbehälter axial einstellbar. Über Kontermuttern wird die korrigierte Arbeitsstellung fixiert.In a particular embodiment of the invention, either the rotating or the stationary part of the pre-shredding device can be axially adjustable, whereby the gap width can be changed during, before or after the production process. In a purely mechanical embodiment of the invention, both the rotating and the stationary part of the pre-shredding device are axially adjustable via threads on the agitator shaft or on the grinding container. Lock nuts fix the corrected working position.
In einer Weiterbildung der vorgenannten erfinderischen Gestaltung sind das rotierende und/oder das stehende Teil der Vorzerkleinerungseinrichtung durch elektrische oder hydraulische Stellglieder in ihrer Position korrigierbar. Die über externe Befehlselemente initiierbaren Kolben oder Elektroantriebe erlauben somit einen direkten Eingriff auf die Vorzerkleinerung und damit auch einen Eingriff auf die Feinheit des dem Mahlprozeß zugeführten Produkts.In a development of the aforementioned inventive design, the rotating and / or the stationary part of the pre-shredding device can be corrected by electrical or hydraulic actuators in their position. The initiatable via external command elements piston or electric drives thus allow a direct intervention on the pre-crushing and thus also an intervention on the fineness of the grinding process supplied product.
