Abstract

The invention relates to a mill comprising a motor-driven grinding container (1) for receiving the material to be ground. The grinding container (1) is rotated by a rotary arm (8) of the drive about an axis of rotation (A) located outside the container, yet at the same time remains non-rotatable about the centre axis (B) thereof by a gear mechanism (9a, 9b, 9c). The grinding balls (12), which can move freely in the grinding container (1), are thus thrown back and forth from wall to wall without any appreciable share of the kinetic energy thereof being lost, for instance due to collisions with each other.

Description

Mühle sowie Verfahren zum Mahlen von Mahlgut mit derselben  Mill and method for grinding regrind with the same
Die Erfindung betrifft eine Mühle mit einem motorisch angetriebenen Mahlbehälter und darin frei beweglichen Mahlkörpern. The invention relates to a mill with a motor-driven grinding container and free-moving grinding media therein.
Derartige Mühlen werden insbesondere zum Feinmahlen von mineralischen Werkstoffen, etwa zur Herstellung von Nanopartikeln oder Nano- pulvern aus solchen Werkstoffen eingesetzt. Bei den bisher bekannten Mühlen dieser Art ist der Wirkungsgrad zwischen der eingebrachten Energie und der tatsächlich genutzten Energie zum Brechen des Mahlgutes unbefriedigend. Daraus resultiert ein hoher Verschleiss der Mahlkör- Such mills are used in particular for the fine grinding of mineral materials, for example for the production of nanoparticles or nanopowders from such materials. In the previously known mills of this type, the efficiency between the introduced energy and the energy actually used for breaking the ground material is unsatisfactory. This results in a high wear of the Mahlkör-

Der schlechte Wirkungsgrad kann zudem eine hohe Temperaturentwicklung im Mahlgut zufolge haben, so dass eine aktive - K-ühlung-des-Mahlguts erforderlich ist, um ungewollte Eigenschaftsveränderungen oder Reaktionen des Mahlgutes zu vermeiden. CONFIRMATION COPY per and the associated contamination of the ground material. The poor efficiency can also have a high temperature development in the millbase, so that an active - K-illung-des-Mahlguts is required to avoid unwanted property changes or reactions of the ground material.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine Mühle der eingangs genannten Art zu schaffen, die sich durch ein effizientes Erzeugen insbesondere von Nanopartikeln und durch einen guten energetischen Wirkungsgrad auszeichnet. The invention has for its object to avoid these disadvantages and to provide a mill of the type mentioned above, which is characterized by an efficient generation in particular of nanoparticles and by a good energy efficiency.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Mahlbehälter annährend quaderförmig ausgebildet ist und durch das Antriebssystem der Mühle in mindestens zwei Dimensionen bewegt wird. Sehr vorteilhaft ist er dabei um seine eigene Mittelachse undrehbar. This object is achieved according to the invention in that the grinding container is approximately parallelepiped-shaped and is moved by the drive system of the mill in at least two dimensions. It is very advantageous in this case about his own central axis undriven.
Auf diese Weise wird erreicht, dass die Mahlkörper im Mahlbehälter vorwiegend hin und her von Wand zu Wand geschleudert werden, und zudem auch durch gegenseitiges Zusammenprallen der Mahlkörper. Die Geometrie bewirkt aber eine bessere stochastische Verteilung der Drehmomente der Mahlkörper und reduziert damit ein energievernichtendes Rollen und Schleifen der Mahlkörper. In this way it is achieved that the grinding media in the grinding container are mainly tossed back and forth from wall to wall, and also by mutual collision of the grinding media. However, the geometry causes a better stochastic distribution of the torques of the grinding media and thus reduces energy-dissipating rolling and grinding of the grinding media.
Entsprechendes gilt auch für die Partikel des Mahlguts, welche mit dieser Mühle sehr effizient zu Nanopartikeln verarbeitet werden können. Ausserdem werden die damit einhergehenden Reibungsverluste herabgesetzt, was auch die Wärmeentwicklung innerhalb des Mahlgutes reduziert. Die Erfindung sieht ferner vor, dass der um seine Mittelachse undrehbare Mahlbehälter durch das Antriebssystem-der-Mühle- um eine ausserhalb des Behälters angeordnete Achse gedreht wird. Dadurch kann er mit einem einfachen Antrieb in zwei Dimensionen bewegt werden. Seine Kreisbahn ist vorzugsweise in einer vorzugsweise horizontalen Ebene angeordnet. Die zweidimensionale Bewegung erfolgt somit entlang der y- Achse und der x-Achse, wobei auch eine Auf- und Ab-Bewegung in z- Richtung möglich wäre. The same applies to the particles of the millbase, which can be processed very efficiently into nanoparticles with this mill. In addition, the associated friction losses are reduced, which also reduces the heat development within the ground material. The invention further provides that the milling container, which can be rotated about its center axis, is rotated by the drive system of the mill about an axis arranged outside the container. This allows it to be moved in two dimensions with a simple drive. Its circular path is preferably arranged in a preferably horizontal plane. The two-dimensional movement thus takes place along the y-axis and the x-axis, whereby an up and down movement in the z-direction would also be possible.
Die Erfindung sieht weiterhin vor, dass das Antriebssystem ein Lagergehäuse mit einer Antriebswelle und einem Dreharm aufweist, dessen ein Ende an der Antriebswelle drehfest befestigt ist und dessen andere Ende den Mahlbehälter trägt, wobei dieser mittels eines Zahnradgetriebes relativ zum Dreharm mit gleicher Geschwindigkeit und in entgegengesetzter Drehrichtung wie der Dreharm gedreht wird. Dies bewirkt, dass der Mahlbehälter während seiner Drehung um die Drehachse des Dreharms gleichzeitig um die eigene Mittelachse undrehbar bleibt. The invention further provides that the drive system comprises a bearing housing having a drive shaft and a rotary arm, one end of which is rotatably attached to the drive shaft and the other end carries the grinding container, said by means of a gear transmission relative to the rotating arm at the same speed and in opposite Direction of rotation as the turning arm is rotated. This causes the grinding container during its rotation about the axis of rotation of the rotary arm at the same time remains unrotatable about its own central axis.
Der quaderförmige Mahlbehälter ist zweckmässigerweise mit 85° bis 95° betragenden Innenwinkeln ausgebildet. Zur Vereinfachung der Fertigung ist es vorteilhaft, wenn der Mahlbehälter einen rechteckigen Querschnitt aufweist, wobei die Seitenwände zum Mahlbehälterboden hin eine leichte Krümmung zur Behältermitte hin aufweisen können. The cuboid grinding container is expediently formed with 85 ° to 95 ° amount inner angles. To simplify the production, it is advantageous if the grinding container has a rectangular cross-section, wherein the side walls may have a slight curvature toward the container center towards the container center.
Die im Mahlbehälter frei beweglichen Mahlkörper sind erfindungsgemäss als Mahlkugeln ausgebildet, was dazu beiträgt, die Reibungsverluste beim Mahlprozess zu minimieren. Es ist im Sinne eines optimierten Mahlergebnisses von Vorteil, wenn die Mahlkörper eine -multimodale Grössenverteilung aufweisen. Es kann auch in diesem Sinne vorteilhaft sein , wenn die Anzahl Mahlkugeln so bemessen ist-- dass ihre -Füll menge ca. 1/3 des Gesamtinhaltsraumes des Mahlbehälters entspricht. The freely movable grinding media in the grinding container are designed according to the invention as grinding balls, which helps to minimize the friction losses during the grinding process. It is in the sense of an optimized Mahlergebnisses advantageous if the grinding media have a -multimodale size distribution. It may also be advantageous in this sense, if the number of grinding balls is sized - that their -Füll amount corresponds to about 1/3 of the total content of the grinding container.
Die erfindungsgemässe Mühle zeichnet sich auch dadurch aus, dass ihre Betriebsweise leicht dem jeweils vorgesehenen Mahlprozess anpassbar ist. Es ist insbesondere leicht möglich, den Mahlbehälter intervallartig und/oder mit alternierenden Richtungswechseln anzutreiben. The mill according to the invention is also distinguished by the fact that its mode of operation is easily adaptable to the grinding process provided in each case. In particular, it is easily possible to drive the grinding container at intervals and / or with alternating changes of direction.
Durch gleichzeitiges Zuführen, Herausziehen oder -drücken sowie Aussieben des Mahlguts ist es nach der Erfindung möglich, das Mahlverfahren als kontinuierlich ablaufendes Verfahren zu gestalten. Zuführ- und Absaugleitungen sind hierbei vorzugsweise im Deckel des Mahlbehälters angeordnet. By simultaneous feeding, pulling or pressing and screening of the ground material, it is possible according to the invention to design the grinding process as a continuously running process. Supply and suction lines are preferably arranged in the lid of the grinding container.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigen: The invention will be explained in more detail with reference to an embodiment with reference to the drawing. Show it:
Fig. 1 den Mahlbehälter samt Antrieb einer erfindungsgemäss Mühle, in der Seitenansicht und schematisch dargestellt, und1 shows the grinding container including drive a mill according to the invention, in the side view and shown schematically, and
Fig. 2 einen Schnitt entlang der Linie II-II in Fig. 1 , ebenfalls schematisch dargestellt. Fig. 2 is a section along the line II-II in Fig. 1, also shown schematically.
Wie aus Fig. 1 und Fig. 2 ersichtlich, ist der Mahlbehälter 1 zur Aufnahme des Mahlgutes quaderförmig ausgebildet, mit einem Boden 2, Seitenwänden 3a bis 3d und einem Deckel 4, der bei Bedarf abnehmbar ist. Der Mahlbehälter 1 hat ebene Wände und einen rechteckigen Quer- schnitt und wird durch ein Antriebssystem 5 angetrieben, der sich aus einem Lagergehäuse 6 mit einer Antriebswelle 7 und einem Dreharm 8 mit einem Zahnradgetriebe 9a, 9b, 9c zusammensetzt- As can be seen from FIG. 1 and FIG. 2, the grinding container 1 is rectangular in shape for receiving the material to be ground, with a base 2, side walls 3a to 3d and a cover 4 which can be removed as required. The grinding container 1 has flat walls and a rectangular transverse is driven by a drive system 5, which consists of a bearing housing 6 with a drive shaft 7 and a rotary arm 8 with a gear transmission 9a, 9b, 9c
Der Mahlbehälter 1 ist mit einem an seinem Boden 4 befestigten Tragzapfen 10 versehen, der am äusseren Ende des Dreharmes 8 gelagert ist. Letzterer ist an seinem anderen Ende an der Antriebswelle 7 befestigt und dreht sich um deren Achse A mit Drehgeschwindigkeit ωΑ in einer vertikalen Ebene auf einer Kreisbahn 1 1 mit Radius R. Dabei wird der Mahlbehälter 1 mitgenommen und dadurch zweidimensional in Richtung der y-Achse und der x-Achse mitbewegt. Gleichzeitig bewirkt das Zahnradgetriebe 9a, 9b, 9c, dass der Mahlbehälter 1 um seine Mittelachse B undrehbar bleibt, indem er relativ zum Dreharm 8 mit gleicher Drehgeschwindigkeit ωΒ = ωΑ aber in entgegengesetzter Drehrichtung wie der Dreharm 8 gedreht wird. The grinding container 1 is provided with a trunnion 10 attached to its bottom 4, which is mounted at the outer end of the rotary arm 8. The latter is attached at its other end to the drive shaft 7 and rotates about its axis A with rotational speed ωΑ in a vertical plane on a circular path 1 1 with radius R. In this case, the grinding container 1 is taken and thereby two-dimensionally in the direction of the y-axis and moved along the x-axis. At the same time, the gear mechanism 9a, 9b, 9c causes the grinding container 1 to remain non-rotatable about its central axis B by being rotated relative to the rotating arm 8 at the same rotational speed ωΒ = ωΑ but in the opposite direction of rotation as the rotating arm 8.
Im Mahlbehälter 1 befindet sich eine Anzahl Mahlkugeln 12, deren Grösse und Beschaffenheit mit der des Mahlguts abgestimmt ist, und deren Füllmenge ca. 1/3 des Gesamtinhaltsvolumens des Mahlbehälters 1 entspricht. Eine solche Füllmenge trägt in der Praxis dazu bei, das Mahlergebnis zu optimieren. Es ist hierbei vielfach vorteilhaft, wenn die Mahlkugeln 12 eine multimodale Grössenverteilung aufweisen. Die Mahlkugeln sind sphärisch ausgebildet. Sie können aber auch eiförmig sein. In the grinding container 1 is a number of grinding balls 12 whose size and texture is matched with the ground material, and their capacity corresponds to about 1/3 of the total volume of the grinding container 1. Such a filling amount contributes in practice to optimize the grinding result. It is in this case often advantageous if the grinding balls 12 have a multimodal size distribution. The grinding balls are spherical. But they can also be egg-shaped.
Die Mahlkugeln 12 sind im Mahlbehälter 1 frei beweglich. Da dieser um seine Mittelachse B undrehbar ist, werden sie darin im Betrieb von Wand zu Wand hin und her geschleudert, ohne dass ein nennenswerter Anteil ihrer kinetischen Energie etwa durch Zusammenprallen der Mahlkugeln vernichtet wird. Die erfindungsgemässe Mühle hat dadurch einen hohen energetischen Wirkungsgrad, der nicht nur wirtschaftliche, sondern auch verfahrenstechnische Vorteile mit sich bringt. Letztere resultieren aus der Verringerung der Reibungsverluste und der damit einhergehenden Wärmeentwicklung im Mahlgut. Die Vermeidung von reibungsbedingten Verunreinigungen und/oder wärmebedingten Reaktionen führt zu einer Qualitätsverbesserung des gemahlenen Produkts. The grinding balls 12 are freely movable in the grinding container 1. Since this is non-rotatable about its central axis B, they are hurled back and forth in operation from wall to wall, without a significant portion of their kinetic energy, for example, by collision of the grinding balls is destroyed. The inventive mill thus has a high energy efficiency, which brings not only economic, but also procedural advantages. The latter result from the reduction of friction losses and the associated heat development in the millbase. The avoidance of friction-related impurities and / or heat-related reactions leads to an improvement in the quality of the ground product.
Beim beschriebenen Ausführungsbeispiel ist die zweidimensionale Bewegungsbahn 12 des Mahlbehälters vertikal. Sie kann aber auch im Rahmen der Erfindung ohne weiteres waagerecht sein, oder aber dreidimensional, etwa indem der Mahlbehälter Schwingungen in den drei Dimensionen ausgesetzt wird. Die erfindungsgemässe Anordnung ermöglicht es auch, den Mahlbehälter intervallartig und /oder mit alternierenden Richtungswechseln anzutreiben. In the described embodiment, the two-dimensional trajectory 12 of the grinding container is vertical. But it can also be within the scope of the invention without further horizontal, or in three dimensions, such as by the grinding container is exposed to vibrations in the three dimensions. The arrangement according to the invention also makes it possible to drive the grinding container at intervals and / or with alternating changes of direction.
Es ist auch im Rahmen der Erfindung möglich, den Querschnitt des Mahlbehälters 1 leicht abweichend von der rechteckigen Form auszugestalten, wobei die Innenwinkel des Behälters vorzugsweise zwischen 85° und 95° variieren. Es ist auch möglich, den Mahlbehälter 1 mit leicht gekrümmten bzw. leicht angeschrägten Seitenwänden zu versehen, die zum Behälterboden hin eine Krümmung bzw. Schräge zur Behältermitte hin aufweisen. It is also possible within the scope of the invention to design the cross-section of the grinding container 1 slightly different from the rectangular shape, wherein the inner angle of the container preferably vary between 85 ° and 95 °. It is also possible to provide the grinding container 1 with slightly curved or slightly beveled side walls, which have a curvature or slope towards the container center towards the container bottom.
Die Erfindung ermöglicht ferner die Ausgestaltung des Mahlverfahrens als kontinuierliches Verfahren, nämlich durch gleichzeitiges Zuführen, Herausziehen oder -drücken sowie Aussieben des Mahlguts. Hierbei sind die Zuführ- und Absaugleitungen vorzugsweise im abnehmbaren Deckel 4 des Mahlbehälters 1 untergebracht. The invention further enables the design of the grinding process as a continuous process, namely by simultaneous feeding, pulling out or pressing and sifting out the ground material. in this connection the supply and suction lines are preferably housed in the removable lid 4 of the grinding container 1.
Zur Verminderung von Pulverablagerungen an den Wänden und Ecken des Behälters ist es zweckmässig, entsprechende Fluidisierungseinrich- tungen vorzugsweise in Ecken und Boden des Behälters einzubauen. To reduce powder deposits on the walls and corners of the container, it is expedient to install corresponding fluidizing devices, preferably in the corners and bottom of the container.
Die erfindungsgemässe Mühle eignet sich besonders für die Herstellung von Submikron- und Nanopulvern aus makroskopischen spröden Werkstoffen, wie insbesondere Diamant, Oxide, oder Karbide, sowie für die Herstellung von Kompositpulvern und mit Nanopartikeln und/oder Nano- tubes, insbesondere CNT verstärken Werkstoffen, wobei die weichere Matrix vor allem aus Metallen, Leichtmetallen und deren Legierungen oder aus Kunststoffen und/oder deren Mischungen besteht. The inventive mill is particularly suitable for the production of submicron and nanopowder from macroscopic brittle materials, such as in particular diamond, oxides, or carbides, and for the production of composite powders and nanoparticles and / or nanotubes, in particular CNT reinforce materials, said the softer matrix mainly consists of metals, light metals and their alloys or of plastics and / or mixtures thereof.
Mit dieser Mühle kann auch ein Mahlen unter Schutzgas, Vakuum oder reaktiven und /oder angeregten, wie beispielsweise plasmaaktivierten oder teilionisierten Gasen erfolgen. Letzteres würde die kontrollierte Herstellung von Submicron-Pulvern bzw. Nanopulvern aus Nitriden, Karbiden, Oxiden entsprechender Metalle, Metalllegierungen und/oder Mischungen erlauben, bis hin zur Herstellung von komplexen, nanostruktu- rierten Pulvern. Man vermischt Metalle, die zum einen eine hohe Reaktivität zu Sauerstoff, Kohlenstoff bzw. Stickstoff haben (Ti, Ta, W, AI etc.), mit Metallen geringerer Reaktivität (Ni, Cu, Ag etc.). Dadurch kann man auf der einen Seite die Härte und auf der anderen Seite die Zähigkeit eines Werkstoffes gezielt beeinflussen. Das Mahlgut soll möglichst ständig in Bewegung gehalten werden, um so den Mahlprozess effizienter zu gestalten und Anbackungen zu vermeiden. With this mill, grinding under protective gas, vacuum or reactive and / or excited, such as plasma-activated or partially ionized gases can be carried out. The latter would allow the controlled production of submicron powders or nanopowders from nitrides, carbides, oxides of corresponding metals, metal alloys and / or mixtures, up to the production of complex nanostructured powders. Mixed metals, which have a high reactivity to oxygen, carbon or nitrogen (Ti, Ta, W, AI, etc.), with metals of lower reactivity (Ni, Cu, Ag, etc.). As a result, it is possible to influence the hardness on the one hand and the toughness of a material on the other. The material to be ground should be kept constantly in motion so as to make the grinding process more efficient and avoid caking.
Die Erfindung ist mit dem erläuterten Ausführungsbeispiel ausreichend dargetan. Selbstverständlich könnte sie noch durch andere Varianten veranschaulicht sein. So könnten beispielsweise anstelle eines Zahnradgetriebes für den Antrieb der Mühle auch Zahnriemen oder ähnlichem verwendet werden. The invention is sufficiently demonstrated with the illustrated embodiment. Of course, it could still be illustrated by other variants. For example, instead of a gear transmission for driving the mill, toothed belts or the like could be used.
Mit der erfindungsgemässen Mühle soll auch Mahlgut, welches entnommen worden ist und noch nicht die gewünschte Korngrösse aufweist, nochmals einem Mahlprozess zugeführt werden. With the mill according to the invention also regrind, which has been removed and does not yet have the desired grain size, should be fed again to a grinding process.
Der Mahlbehälter wird vorzugsweise auf einer Kreisbahn in einer horizontalen Ebene bewegt. Diese Ebene kann aber auch in einem vorgegebenen Winkel, vertikal oder sich verändernd ausgerichtet sein. The grinding container is preferably moved on a circular path in a horizontal plane. However, this plane can also be oriented at a predetermined angle, vertically or in a changing manner.
Der Mahlbehälter könnte durch das Antriebssystem der Mühle in allen drei Dimensionen bewegt werden, indem beispielsweise noch eine Rüttelbewegung übergeordnet ist. Auch diese Undrehverbarkeit des Mahlbehälters in Bezug auf seine Mittelachse (B) könnte durch eine Steuerung in eine beschränkte gleich- oder ungleichmässige Drehbewegung ersetzt werden. The grinding container could be moved by the drive system of the mill in all three dimensions, for example, is still a parent shaking movement. This Undrehverbarkeit the Mahlbehälters with respect to its central axis (B) could be replaced by a control in a limited equal or non-uniform rotational movement.
