Description

Die Erfindung betrifft einen Kollergang mit zumindest einem um eine Königswelle od. dgl. drehenden Läuferpaar aus mehreren Läufern.The invention relates to a pan mill with at least one around a vertical shaft or the like rotating pair of runners several runners.

Unter einem Kollergang wird eine Zerkleinerungsmaschine verstanden, bei der mehrere um eine horizontale Achse routierende und um eine senkrechte Königswelle umlaufende schwere Stahl- oder Steinwalzen ein Gut zwischen sich und einer feststehenden oder sich drehenden Mahlbahn zerdrükken. Heute handelt es sich bei dem Gut meist um keramische Massen, die auf diese Weise behandelt werden.A crushing machine is under a pan mill understood, in which several routing around a horizontal axis and around a vertical royal wave heavy steel or stone rollers a good between themselves and crush a fixed or rotating grinding track. Today, the estate is mostly ceramic Masses treated in this way.

Meist sind Kollergänge bekannt, bei denen nur ein Läufer pro Drehachse vorgesehen ist. Jeder Läufer hat seine eigene Mahlspur oder läuft teilweise in der Mahlspur eines anderen Läufers.Usually pan millers are known, in which only one runner is provided per axis of rotation. Every runner has his own Milling track or partially running in someone else's milling track Runner.

Effizienter sind jedoch Kollergänge, welche mit Läuferpaaren arbeiten. However, runner blocks with pairs of runners are more efficient work.

Bekannte Läuferpaare sind zwar an einer gleichen Drehachse angeordnet, laufen jedoch je nach ihrer Entfernung von der Königswelle mit unterschiedlicher Geschwindigkeit. Derartige Kollergänge sind bspw. in der DE-PS 175 299 und der DE-PS 180 167 beschrieben. Diese Läuferpaare haben allerdings den Nachteil, daß die zwischen der Mahlbahn und dem Umfang jedes Läufers gebildeten Reibflächen relativ gering sind und dementsprechend der Wirkungsgrad des Kollergangs beschränkt ist.Known pairs of runners are on the same axis of rotation arranged, but run depending on their distance from the Vertical shaft at different speeds. such Cauldron courses are, for example, in DE-PS 175 299 and DE-PS 180 167 described. However, these pairs of runners have the disadvantage that the between the grinding track and The circumference of each runner is relatively small are and accordingly the efficiency of the pan mill is limited.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den Wirkungsgrad besonders in Bezug auf Reib- bzw. Schwerwirkung des Kollergangs wesentlich zu verbessern.The present invention is based on the object Efficiency especially with regard to friction or heavy effects to significantly improve the pan mill.

Zur Lösung dieser Aufgabe führt, daß die Läufer eines Läuferpaares verdrehgesichert miteinander verbunden sind.To solve this problem, the runners of a pair of runners are secured against rotation.

Das bedeutet, daß die Läufer eines Läuferpaares mit gleicher Geschwindigkeit um die Achse drehen. Es werden zum einen zumindest zwei nebeneinander liegende Mahlspuren gleichzeitig überrollt, zum anderen ergibt sich eine doppelt so große Reib- bzw. Schrotfläche pro Läuferumdrehung. Dies liegt daran, daß die Ebene, in der auf der Mahlbahn keine Reibung stattfindet, zwischen den beiden Läufern eines Läuferpaares hindurch verläuft, so daß die gesamte Oberfläche des Läuferumfangs an der Reibung mit der Mahlbahn teilnimmt und zwar in einem je größeren Umfang, je weiter der Läuferumfang nach außen oder nach innen sich von der Mittelebene zwischen den beiden Läufern entfernt. Hierdurch ergibt sich für einen Doppelläufer ein neuer, mittlerer Abrollradius, der, theoretisch, bezogen auf den Innenläufer, um die halbe Läuferbreite größer, und, bezogen auf den Außenläufer, um die halbe Läuferbreite kleiner ist.This means that the runners of a pair of runners have the same Turn the speed around the axis. It becomes one at least two grinding marks lying next to each other rolled over at the same time, on the other hand there is double so large friction or shot area per rotor revolution. This is because the level in which on the grinding track no friction takes place between the two runners of a pair of runners runs through, so that the entire Surface of the rotor circumference on the friction with the Mahlbahn participates and to a greater extent, depending further the runner circumference outwards or inwards the middle plane between the two runners. hereby there is a new one for a double runner mean rolling radius, which, theoretically, related to the Inner runner, half the width of the runner, and covered to the outer rotor, is half the rotor width smaller.

Durch die größere Reibfläche zwischen Läufer und Mahlbahn ergibt sich wiederum ein höherer Aufbereitungsgrad des Mahlgutes infolge der wesentlich größeren Zerkleinerungsarbeit und der damit verbundenen Steigerung der Knet,-Misch- und Homogenisierungswirkung. Ein höherer Wirkungsgrad der Doppelläufer ergibt sich auch dadurch, daß ein seitlicher Mahlgutaustritt nur an vier Läuferseiten erfolgt, statt, wie bei den Entgegenhaltungen, an acht Seiten.Due to the larger friction surface between the rotor and the grinding track again results in a higher degree of preparation of the Grist as a result of the much larger shredding work and the associated increase in kneading, mixing and homogenization effect. A higher efficiency the double runner also results from the fact that a side regrind only emerges on four runner sides, instead of eight pages, as in the references.

Benötigt werden ferner nur zwei Drehachsen für vier Läufer und auch nur zwei Läuferlagerungen anstelle von vier. Zur Installation eines mehrstufigen Schabersystems steht mehr Platz zur Verfügung, um auch bei kleinen Drehzahlen den Mahlguttransport von der in der Regel ungelochten Innenspur zur gelochten Außenspur zu gewährleisten. Ferner ist die Zugänglichkeit der Maschine für Wartungsarbeiten ähnlich gut wie bei einem Zwei-Läufersystem.Only two axes of rotation for four runners are required and only two rotor bearings instead of four. to Installation of a multi-stage doctor system is more Space available to the even at low speeds Grist transport from the usually unpunched inner track to ensure the perforated outer track. Furthermore, the Accessibility of the machine for maintenance work similar just like a two-runner system.

Wenn im vorliegendem Fall von "Läuferpaar" gesprochen wird, so erfaßt die Erfindung auch den Gedanken, daß mehr als zwei Läufer an einer Achse angeordnet sind und verdrehgesichert miteinander verbunden sind. Hier können verschiedene Ausgestaltungen, je nach Wunsch, gewählt werden.If in the present case the term "pair of runners" is used, the invention also embraces the idea that more than two runners are arranged on one axis and secured against rotation are interconnected. Here can be different Designs can be selected as desired.

Vor allem bei sehr hartem Mahlgut, wie insbesondere keramischen Massen od. dgl., ist es notwendig, die beiden Läufer eines Läuferpaares unabhängig voneinander in der Vertikalen bewegbar auszugestalten. Nur so wird gewährleistet, daß ein Läufer infolge eines harten Mahlgutes angehoben werden kann, während der andere Läufer auf einer tieferen Mahlspur abläuft.Especially with very hard regrind, especially ceramic ones Masses or the like, it is necessary for the two runners of a pair of runners independently of one another in the vertical designed to be movable. This is the only way to ensure that a Runners may be lifted due to hard ground material can while the other runner is on a deeper grinding track expires.

Damit diese vertikale Bewegbarkeit gegeben, jedoch andererseits die Verdrehsicherung beibehalten ist, sollten die Läufer eines Läuferpaares miteinander verbunden sein. Dies kann auf beliebiger Art und Weise erfolgen. Bspw. können von einem Läufer aus Führungselemente in entsprechende Ausnehmung des anderen Läufers einragen, so daß die beiden Läufer nicht mehr gegeneinander verdreht werden können. So that this vertical mobility exists, but on the other hand the anti-rotation lock is maintained, the Runners of a pair of runners must be connected to each other. This can be done in any way. For example. can from a runner out of guide elements in corresponding Protect the recess of the other runner so that the two Runners can no longer be turned against each other.

Die Führungselemente und die Ausnehmungen sind dann so ausgestaltet, daß der eine Läufer gegenüber dem anderen Läufer in der Höhe verändert werden kann. Hierdurch wird auch die spezifische Flächenpressung des anderen Läufers verbessert.The guide elements and the recesses are then designed that one runner versus the other runner can be changed in height. This will also specific surface pressure of the other runner improved.

Ein weiterer Gedanke bezieht sich auf die Anordnung der Drehachse gegenüber der Königswelle. Wird die Drehachse für das Läuferpaar exzentrisch angeordnet, so erfolgt ein gewisses Nachschleppen des Läuferpaares bei Drehung der Königswelle. Hierdurch werden die Läufer über die Mahlspuren gezogen, so daß nochmals der Wirkungsgrad der Zerkleinerungsarbeit verbessert ist. Another thought relates to the arrangement of the Axis of rotation opposite the vertical shaft. If the axis of rotation for the pair of runners arranged eccentrically, so there is a certain Dragging of the pair of runners while rotating the vertical shaft. This will run the runners over the grinding marks drawn so that again the efficiency of the crushing work is improved.

  • Gemäß Figur 1 ist eine Mahlbahn 1 vorgesehen, auf der zwei Läuferpaare 2 und 3 laufen. Jedes Läuferpaar 2, 3 ist über eine Drehachse 4, 5 mit einer vertikal aufragenden Königswelle 6 verbunden, wobei diese Königswelle 6 in der Regel im Uhrzeigersinn um eine Achse A dreht. Die Mahlspuren der Läufer auf der Mahlbahn 1 sind gestrichelt angedeutet. Für einen jeweils inneren Läufer 7 gilt die Mahlspur 8, für einen jeweils äußeren Läufer 9 die Mahlspur 10.According to Figure 1, a grinding track 1 is provided on the two Runner pairs 2 and 3 run. Each pair of runners 2, 3 is over an axis of rotation 4, 5 with a vertically rising vertical shaft 6 connected, this vertical shaft 6 usually rotates clockwise around an axis A. The traces of grinding the Runners on the grinding track 1 are indicated by dashed lines. For the grinding track 8 applies to each inner runner 7 one outer runner 9 each, the grinding track 10.

    Erfindungsgemäß liegen die beiden Läufer 7 und 9 verdrehgesichert auf der Drehachse 4/5 fest. D.h., sie drehen mit der gleichen Geschwindigkeit um die Drehachse 4/5, so daß der äußere Läufer 9 gegenüber dem inneren Läufer 7 gehemmt läuft. Hierdurch wird ein relativ große Reibfläche zwischen dem Läuferumfang und der Mahlbahn 1 erzielt, wie dies in Figur 5 dargestellt ist. According to the invention, the two runners 7 and 9 are secured against rotation fixed on the axis of rotation 4/5. That is, they rotate with it the same speed around the axis of rotation 4/5, so that the outer rotor 9 is inhibited with respect to the inner rotor 7 running. This creates a relatively large friction surface between the rotor circumference and the grinding track 1 achieved, as in Figure 5 is shown.

    Bei herkömmlichen Läuferpaaren drehen die Läufer mit unterschiedlicher Geschwindigkeit, so daß sich pro Läuferpaar jeweils vier relativ kleine Reibflächen 11.1 - 11.4 (siehe Figur 4) ergeben. In der jeweiligen Mittenebene E1 bzw. E2 jedes Läufers ergibt sich keine Reibfläche. Nur die inneren und äußeren Umfangsbereiche jedes Läufers ergeben, je nach der Entfernung von der Mittenebene E1 bzw. E2, eine mehr oder weniger große Reibfläche.In conventional pairs of rotors, the rotors rotate with different ones Speed, so that per pair of runners four relatively small friction surfaces 11.1 - 11.4 (see Figure 4) result. In the respective center level E1 or E2 each runner has no friction surface. Only the inside and outer peripheral areas of each runner, depending on the distance from the center plane E1 or E2, one more or less large friction surface.

    Werden dagegen zwei Läufer 7 und 9 drehgesichert miteinander verbunden, so wird für jedes Läuferpaar 2, 3 nur eine gemeinsame Mittelebene ME gebildet, so daß vor allem die äußeren Bereiche jedes Läufers fern von der Mittelebene ME eine wesentlich größere Reibfläche ausbilden. Dies führt zu einer insgesamt wesentlich höheren Reibfläche 11.5 bzw. 11.6 für jeden Läufer 7, 9.In contrast, two runners 7 and 9 are secured against rotation with one another connected, only one for each pair of runners 2, 3 common middle plane ME formed, so that especially the outer areas of each runner far from the median plane ME form a much larger friction surface. this leads to an overall much higher friction surface 11.5 or 11.6 for each runner 7, 9.

    Die verdrehgesicherte Verbindung der beiden Läufer 7, 9 eines jeden Läuferpaares 2, 3 soll jedoch so erfolgen, daß die Läufer 7, 9 vertikal zueinander bewegbar sind. Dies ist insbesondere bei relativ hartem Mahlgut notwendig, damit bei einem Ansteigen des einen Läufers 7, 9 nicht der andere Läufer 9, 7 von der Mahlbahn 1 abgehoben wird, wodurch die Mahltätigkeit des gesamten Kollerganges wesentlich beeinträchtigt wäre.The anti-rotation connection of the two runners 7, 9 one however, each pair of runners 2, 3 should be such that the runners 7, 9 can be moved vertically to one another. This is necessary especially with relatively hard regrind when one runner 7, 9 rises, the other does not Runner 9, 7 is lifted off the grinding track 1, whereby the Grinding activity of the entire pan mill significantly impaired would.

    Für die Ausgestaltung der Verdrehsicherung und der vertikalen Bewegbarkeit der beiden Läufer 7, 9 sind viele Möglichkeiten denkbar. Nur eine Möglichkeit ist in den Figuren 2 und 3 angedeutet. Hierbei weist jede Fläche eines Läufergrundkörpers 12.1 bzw. 12.2 einen etwa zentrischen Ringkanal 13.1 bis 13.4 auf. In den inneren Ringkanälen 13.2 und 13.3 zwischen zwei Läufergrundkörpern 12.1 und 12.2 sitzt eine elastische Kupplung 14 mit Luftbalg, die ebenfalls als Ring ausge-bildet ist. For the design of the anti-rotation and vertical Movability of the two runners 7, 9 are many options conceivable. Only one way is in the figures 2 and 3 indicated. In this case, each surface of a basic rotor body 12.1 or 12.2 an approximately centric ring channel 13.1 to 13.4. In the inner ring channels 13.2 and 13.3 sits between two rotor bodies 12.1 and 12.2 an elastic coupling 14 with air bellows, which also as Ring is formed.

    Querschnittlich stellt sie ein auf dem Kopf stehendes U dar, wobei ihre beiden Schenkel 15.1 und 15.2 über Druckringe 16.1 und 16.2 gegen einen jeweiligen Kanalboden 17.1 bzw. 17.2 gepreßt werden. Dieses Anpressen erfolgt durch eine Mehrzahl von Zugschrauben 18.1 bzw. 18.2, welche den jeweiligen Läufergrundkörper achsparallel durchsetzen, wobei ein entsprechender Schraubenkopf 19.1 bzw. 19.2 jeweils in dem äußeren Ringkanal 13.1 bzw. 13.4 versenkt ist.In cross-section, it represents an upside down U. represents, with their two legs 15.1 and 15.2 via pressure rings 16.1 and 16.2 against a respective channel floor 17.1 or 17.2 are pressed. This pressing takes place through a plurality of lag screws 18.1 and 18.2, which the Push through the respective rotor base body parallel to the axis, whereby a corresponding screw head 19.1 or 19.2 each is sunk in the outer ring channel 13.1 or 13.4.

    Jeder Läufergrundkörper 12.1 bzw. 12.2 ist von einem Läuferring 20.1 bzw. 20.2 umfangen, der bspw. bei einem Verschleiß austauschbar ist.Each rotor base body 12.1 or 12.2 is of a rotor ring 20.1 or 20.2, for example, in the event of wear is interchangeable.

    Im vorliegenden Ausführungsbeispiel ist die Drehachse 4/5 über eine Schleppkurbel 21 mit einem nicht näher gezeigten Achsstummel verbunden, der wiederum an die Königswelle 6 anschließt. Da dies bei bekannten Kollern ebenfalls gezeigt ist, wird auf eine nähere Beschreibung verzichtet.In the present exemplary embodiment, the axis of rotation is 4/5 via a drag crank 21 with a not shown Axle stub connected, which in turn to the king shaft 6 followed. Since this is also shown in known paners a detailed description is dispensed with.

    Die Drehachse 4/5 ist in dem Läufergrundkörper 12.1 normal über bspw. zwei Wälzlager 32.1, 32.2 gelagert, verjüngt sich danach zu einem Gelenkstück 22 und zu einem Achsstummel 23, der wiederum in einem Axiallager 24 und einem Stützlager 27 gelagert ist. Auf die Axiallagerung 24 folgt eine Stützscheibe 25, eine Deckscheibe 26, sowie eine Mutter 28 und Kontermutter 29, welche dem Achsstummel 23 aufgeschraubt sind. Die Lageranordnung 24/27 schlägt an einer Gehäuseschulter 30 in dem Läufergrundkörper 12.2 an, so daß die Drehachse 4/5 zwischen der Stützscheibe 25 und einer die Schleppkurbel 21 unterlegenden Anschlagscheibe 31 verspannt ist. Eine Festlegung der Wälzlager 32 in dem Läufergrundkörper 12.1 erfolgt durch zwei Scheiben 33, die wiederum von einer Mutter 34 und Kontermutter 35 mit Druck beaufschlagt sind.The axis of rotation 4/5 is normal in the rotor body 12.1 mounted on, for example, two roller bearings 32.1, 32.2, tapered then to a joint piece 22 and one Axle stub 23, which in turn in a thrust bearing 24 and a support bearing 27 is mounted. On the axial bearing 24 follows a support plate 25, a cover plate 26, and one Nut 28 and lock nut 29, which the stub axle 23rd are screwed on. The bearing arrangement 24/27 strikes a housing shoulder 30 in the rotor base body 12.2, so that the axis of rotation 4/5 between the support plate 25 and a stop disk 31 underlying the drag crank 21 is tense. A definition of the roller bearing 32 in the Basic rotor body 12.1 is made by two disks 33 which again from a nut 34 and lock nut 35 with pressure are acted upon.

    In Figur 3 ist erkennbar, daß das Gelenkstück 22 in den Achsen B und C gelagert ist, was bedeutet, daß der Läufer 9 gegenüber dem Läufer 7 in Richtung des Doppelpfeiles 36 bewegbar ist. Bei einer Bewegung in Richtung des Doppelpfeiles 36 gibt die elastische Kupplung 14 nach, bewirkt aber gleichzeitig auch durch Anhebung oder Senkung des Gelenkstückes 22 eine Reduktion des Achsabstandes B, C in horizontale Verschiebung der Läufer 7/9 zueinander. Dabei wird der Luftbalg in der Kupplung 14 zusammengepreßt und bewirkt eine Rückstellkraft in die Ausgangstage des jeweiligen Läufers.In Figure 3 it can be seen that the joint piece 22 in the Axes B and C is mounted, which means that the rotor 9th opposite the rotor 7 in the direction of the double arrow 36 is movable. When moving in the direction of the double arrow 36 yields the elastic coupling 14, effected but at the same time also by raising or lowering the Joint piece 22 a reduction in the center distance B, C in horizontal displacement of the runners 7/9 to each other. there the air bellows is compressed in the clutch 14 and causes a restoring force in the starting days of the respective runner.

    Ferner ist erkennbar, daß die beiden Läufer 7 und 9 einen Abstand a voneinander einhalten. Hierdurch wird eine taumelnde Bewegung der Läufer möglich, wobei durch die elastische Kupplung 14 mit Luftbalganordnung immer wieder eine Rückstellung in die Ausgangslage erfolgt.It can also be seen that the two runners 7 and 9 one Keep distance a from each other. This will make a tumbling Movement of the runners possible, with the elastic Coupling 14 with air bellows arrangement always one Reset to the starting position.

    In Figur 1 ist im übrigen erkennbar, daß die Drehachsen 4 und 5 exzentrisch mit der Königswelle 6 verbunden sind. Dies bewirkt ein gewisses Nachschleifen der Läuferpaare, wenn die Königswelle 6 in Drehrichtung z gedreht wird. Hierdurch wird die Mahlung und Scherung des Mahlgutes nochmals verbessert.

This causes a certain regrinding of the rotor pairs when the vertical shaft 6 is rotated in the direction of rotation z. This further improves the grinding and shearing of the ground material.
