Description

Die Erfindung betrifft eine Exzenter-Schwingmühle gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an eccentric vibratory mill according to the preamble of claim 1.

Wie bekannt ist, bestehen Schwingmühlen aus zylindrischen, trogähnlichen oder muldenförmigen, auf Gummipuffern oder Federn frei beweglich gelagerten Behältern, die entweder durch eine im Massenmittelpunkt umlaufende oder durch mehrere auf den Massenmittelpunkt abgestimmte Erreger in Form von Unbalanzen annähernd in kreisschwingende Bewegungen versetzt werden. Den in den Mahlbehältern befindlichen Mahlkörpern werden von den schwingenden Mahlbehältern Stöße erteilt, die durch Impulsfortpflanzung in das Innere der Mahlkörperfüllung gelangen. Die Zerkleinerung erfolgt durch Stoß- und Reibungsereignisse zwischen den Mahlkörpern selbst und zwischen den Mahlkörpern und der Behälterwand. Die Mühlenfüllung führt jeweils entgegen der Arbeitsrichtung des Erregers eine Umlaufbewegung aus, wodurch der Transport des Mahlgutes gewährleistet wird.As is known, vibratory mills consist of cylindrical, trough-like or trough-shaped Rubber buffers or springs freely movable Containers either through a center of mass circumferential or by several to the center of mass coordinated pathogens in the form of imbalances almost set in circular oscillating movements will. The grinding media in the grinding bowl are knocked by the vibrating grinding bowl issued by pulse propagation into the interior the grinding media filling. The crushing occurs through shock and friction events between the grinding media themselves and between the grinding media and the container wall. The mill filling leads against the working direction of the Pathogen makes a circular motion, causing the transport of the regrind is guaranteed.

Bei allen heute üblichen Schwingmühlenbauarten (Fertigungsprogramme der Firmen: KHD Humbold Wedag AG, Köln; Aulmann und Beckschulte, Maschinenfabrik Bergneustadt; Siebtechnik GmbH Maschinen- und Apparatebau, Mülheim/Ruhr; IBAG, Neustadt/Weinstraße; Ratzinger GmbH, München) befindet sich der Unwuchterreger im Massenmittelpunkt der Maschinen, so daß von einer annähernden Kreisschwingung ausgegangen werden kann.With all types of vibratory mill types common today (Manufacturing programs of the companies: KHD Humbold Wedag AG, Cologne; Aulmann and Beckschulte, Bergneustadt machine factory; Siebtechnik GmbH mechanical and apparatus engineering, Mülheim / Ruhr; IBAG, Neustadt / Weinstrasse; Ratzinger GmbH, Munich) the unbalance exciter is located in Center of mass of the machines, so that from one approximate circular vibration can be assumed.

Aus der Patentliteratur sind Vorschläge zum Bau von Schwingmühlen bekannt, bei denen aus konstruktiven Gründen der oder die Unwuchterreger zwar außerhalb des Massenmittelpunktes angeordnet sind, die aber in jedem Fall eine Kreisschwingung anstreben. Im US-Patent 3 545 688 ist eine Einrohrschwingmühle beschrieben, bei der das Mahlrohr beidseitig von zwei horizontal angeordneten Unwuchtmotoren in Kreisschwingungen versetzt wird. Gegenstand der DE 34 04 942 A1 ist eine "Mahlvorrichtung zum Zerkleinern von grobstückigem Material". Dazu wird ausgeführt: "Im Betrieb wird die Mahlvorrichtung gemäß der Erfindung mit Hilfe der am Gehäuse angeordneten Unwuchterregermassen in etwa kreisförmige Schwingungen versetzt...".Proposals for construction are from the patent literature known from vibratory mills, from which constructive reasons the or the unbalance exciter arranged outside the center of mass are, but in any case a circular vibration strive for. In U.S. Patent 3,545,688 is a single tube vibratory mill described in which the grinding tube on both sides by two horizontally arranged unbalance motors is made to oscillate in circles. object DE 34 04 942 A1 is a "grinding device for crushing coarse material " is executed: "The grinder is in operation according to the invention using the on the housing arranged unbalance exciter masses approximately circular Vibrations offset ... ".

Ein ähnliches Konstruktionsprinzip weist der Gegenstand der US-Patentschrift 34 25 670 auf. Der Mahlbehälter wird hierbei durch beidseitig angebrachte horizontale Stützfedern zusätzlich zwangsgeführt, so daß lediglich senkrecht stehende elliptische Schwingungen entstehen, durch die eine Beanspruchung des Mahlgutes im Sinne eines Pochwerkes erreicht wird. Wie auch für den Gegenstand der DE 34 04 942 A1 bereits zutreffend, liegt notwendigerweise der Antrieb in der Schwerkraftachse. Einer weiteren Vorrichtung, bei der zwei gegeneinander umlaufende Unwuchterreger sowohl außerhalb als auch innerhalb der Schwerkraftachse der Mahlvorrichtung angeordnet sind, ist als "Vibrating Grinding Mill" in der US 3 391 872 beschrieben. Es handelt sich dabei um das Prinzip der herkömmlichen Sturzmühle (Kugelmühle), bei der zur Verbesserung der Mahlwirkung die übliche Rotation des Mahlbehälters um die horizontal gelagerte Achse zusätzlich durch lineare Schwingungen, hervorgerufen durch die beiden gegeneinander umlaufenden Unwuchterreger, überlagert wird. Die Drehbewegung der Mahlkörperfüllung wird durch Rotation des Mahlbehälters ausgelöst, die entweder frei (als Folge der gerichteten linearen Schwingungen) oder erzwungen (durch einen zusätzlichen Drehantrieb) erfolgen kann und nicht durch die bei üblichen Schwingmühlen vorhandene Zentrifugalbeschleunigung der Unwuchten.
   In der nicht vorveröffentlichten DE 42 42 654 A1 wird ein Verfahren zur Naßfeinst- und Trockenfeinmahlung unter Einsatz einer Lineartrogschwingmühle beschrieben, wobei diese Schwingmühle aus zwei übereinander befindlichen, auf Schwingelementen gelagerten Mahlbehältern besteht und deren zwei Erregereinheiten gemäß den Figuren 1 und 2 exzentrisch einseitig außerhalb der Schwerkraftachse und des Massenmittelpunktes der beiden Mahlbehälter angeordnet sind. Erregereinheit und Mahlbehälter liegen aber zwischen den antriebsseitigen und den dem Antrieb gegenüberliegenden Federnachsen. Bei einer derartigen Anordnung gemäß den Figuren 1 und 2 wird entweder eine Kreisschwingung (Fig.2) oder eine Linearschwingung (Fig.1) erzeugt.
The subject of US Pat. No. 3,425,670 has a similar design principle. The grinding vessel is additionally positively guided by horizontal support springs attached on both sides, so that only vertically standing elliptical vibrations occur, by means of which the material to be ground is stressed in the manner of a knocking mill. As is also true for the subject of DE 34 04 942 A1, the drive necessarily lies in the axis of gravity. Another device, in which two unbalance exciters rotating around one another are arranged both outside and inside the gravity axis of the grinding device, is described as a "Vibrating Grinding Mill" in US Pat. No. 3,391,872. This is the principle of the conventional tumble mill (ball mill), in which, in order to improve the grinding effect, the usual rotation of the grinding container around the horizontally mounted axis is additionally superimposed by linear vibrations caused by the two unbalance exciters rotating around each other. The rotating movement of the grinding media filling is triggered by rotation of the grinding bowl, which can either be free (as a result of the directed linear vibrations) or forced (by an additional rotary drive) and not by the centrifugal acceleration of the unbalances present in conventional vibratory mills.
In the unpublished DE 42 42 654 A1 describes a method for wet and dry fine grinding using a linear trough vibratory mill, this vibratory mill consisting of two superimposed grinding vessels mounted on vibrating elements and the two exciter units according to FIGS. 1 and 2 eccentrically on one side outside of the Gravity axis and the center of mass of the two grinding vessels are arranged. Excitation unit and grinding container are, however, between the drive axles and the spring axles opposite the actuator. With such an arrangement according to FIGS. 1 and 2, either a circular oscillation (FIG. 2) or a linear oscillation (FIG. 1) is generated.

Die genannten Vorschläge konnten sich nicht durchsetzen, da sie gegenüber den im industriellen Einsatz befindlichen Schwingmühlen keinen Vorteil in Bezug auf Durchsatz und spezifischen Energiebedarf bieten.The suggestions mentioned could not prevail, as compared to those in industrial Vibrating mills in use have no advantage in terms of throughput and specific energy requirements Offer.

In einer 1992 erschienen Monographie: Kurrer K.-E. u.a.: "Analyse von Rohrschwingmühlen", Fortschrittsberichte VDI, Reihe Verfahrenstechnik Nr. 282, VDI Verlag 1992, werden Untersuchungen der Bewegungsvorgänge der Mühlenfüllung und der Maschinendynamik vorgestellt. Danach gliedert sich der Mahlraum von Rohrschwingmühlen je nach Erregungsintensität in energiereiche und energiearme Zonen (S. 15 ff). Die energiereichste Zone, die Hauptbeanspruchungszone ist gekennzeichnet durch die stärkste Normalstoß- und Reibstoßkraft (S. 57 ff). Die Reibstoßkraft ist die Voraussetzung für die Umlaufbewegung der Mühlenfüllung. Die Umlaufbewegung der Mühlenfüllung verläuft entgegen der Drehrichtung des Erregers. Bei der üblichen Kreisschwingung von Schwingmühlen kann entsprechend durch Änderung der Drehrichtung des Erregers die Drehrichtung der Mühlenfüllung im Uhrzeigersinn oder entgegen dem Uhrzeigersinn erfolgen. In a monograph published in 1992: Kurrer K.-E. including: "Analysis of vibrating tube mills", progress reports VDI, series process engineering No. 282, VDI Verlag 1992, studies of the Movement processes of the mill filling and the machine dynamics presented. After that, the Grinding room of vibrating tube mills depending on the excitation intensity in high-energy and low-energy zones (P. 15 ff). The most energetic zone, the main stress zone is characterized by the strongest normal impact and friction impact force (p. 57 ff). The friction impact is the prerequisite for that Orbital movement of the mill filling. The orbital movement the mill filling runs counter to the Direction of rotation of the exciter. With the usual circular vibration of vibratory mills can be used accordingly by changing the direction of rotation of the pathogen Direction of rotation of the mill filling clockwise or counterclockwise.

Der Erfindung liegt die Aufgabe zugrunde, durch konstruktive Maßnahmen den Energieeintrag in Schwingmühlen derart zu erhöhen, daß der Anteil der energiearmen Zonen minimiert und die bisher dadurch bedingte obere Grenze des Mahlbehälters- oder Mahlrohrdurchmessers von 650 mm überschritten werden kann.The invention is based, through constructive measures the energy input in To increase vibratory mills so that the proportion of low-energy zones minimized and so far Conditional upper limit of the grinding container or Grinding tube diameter of 650 mm are exceeded can.

Dies geschieht erfindungsgemäß entsprechend der Lehre des kennzeichnenden Teils des Patentanspruches 1.According to the invention, this is done according to the teaching of the characterizing part of claim 1.

Durch diese Anordnung werden die Bewegungsvorgänge der Mühlenfüllung entscheidend verändert. Der Anteil der Linearschwingungen bewirkt eine Erhöhung der Umlaufgeschwindigkeit der Mühlenfüllung gegenüber kreisschwingenden Schwingmühlen um annähernd den Faktor 4, so daß neben der Erhöhung der Normalstoßkraft vor allem eine Erhöhung der Reibstoßkraft zu verzeichnen ist.With this arrangement, the movement processes the mill filling changed decisively. The proportion of linear vibrations causes one Increase in the circulation speed of the mill filling compared to vibrating mills by approximately a factor of 4, so that in addition to the Increasing the normal impact force especially one There is an increase in the frictional impact force.

Kennzeichnend für die erfindungswesentliche einseitige Erregung außerhalb der Schwerkraftachse und des Massenmittelpunktes der Schwingmühle ist, daß im Gegensatz zu den üblichen kreisschwingenden Schwingmühlen die Umlaufbewegung der Mühlenfüllung nur dann erfolgt, wenn bei linksseitiger Anordnung des Erregers dieser im Linkslauf und bei rechtsseitiger Anordnung dieser im Rechtslauf betrieben wird.Characteristic of the one-sided essential to the invention Excitation outside the axis of gravity and the center of mass of the vibratory mill, that in contrast to the usual circular vibrating Vibrating mills the orbital movement of the mill filling only occurs if left-sided Arrangement of the pathogen in counterclockwise rotation and at right-hand arrangement of these operated in clockwise rotation becomes.

Der Vorteil der einseitigen Erregung der Schwingmühle außerhalb der Schwerkraftachse und des Massenmittelpunktes ist, daß das zusätzliche Auftreten von Ellipsen- und Linearschwingungen ganz wesentlich zur Verbesserung der Transportvorgänge durch die Erhöhung der Umlaufgeschwindigkeit beiträgt, was entscheidend für den Mahlfortschritt ist.The advantage of one-sided excitation of the vibratory mill outside the gravity axis and the Center of mass is that the additional Occurrence of ellipse and linear vibrations entirely essential to improve the transportation processes by increasing the orbital speed, which is crucial for the grinding progress.

  • Anhand der in den Figuren 1 und 2 dargestellten Schemata wird die Wirkungsweise des Gegenstandes der Erfindung erläutert. In Fig. 1 wird ein auf (nicht dargestellten) Schwingelementen gelagertes Mahlrohr (1) durch einen auf der linken Seite außerhalb der Schwerkraftachse angeordneten, links umlaufenden Erreger (2) in Schwingungen versetzt. Infolge der einseitigen Erregung führt das Mahlrohr nur erregerseitig Kreisschwingungen (Pfeil 4a) aus, die über Ellipsenschwingungen (Pfeil 4b) im Zentrum in Linearschwingungen (Pfeil 4c) auf der dem Erreger (2) gegenüberliegenden Seite des Mahlrohres übergehen.Using the schemes shown in Figures 1 and 2 the mode of operation of the subject of Invention explained. In Fig. 1 one is on (Not shown) vibrating elements stored Grinding tube (1) through one on the left arranged outside the gravity axis, left rotating exciter (2) vibrated. As a result of the one-sided excitation, the grinding tube leads circular vibrations only on the excitation side (arrow 4a) from the elliptical vibrations (arrow 4b) in the Center in linear vibrations (arrow 4c) on the Exciter (2) opposite side of the grinding tube pass over.

    Bei linksumlaufendem Erreger (2) wird die durch das Bezugszeichen (3) repräsentierte Mühlenfüllung in Rechtsdrehung (Pfeil 5) versetzt. Dabei führt die Mühlenfüllung erregerseitig eine Aufwärtsbewegung (Pfeil 6) und auf der dem Erreger gegenüberliegenden Seite eine Abwärtsbewegung (Pfeil 7) aus. Während die Kreisschwingung (4a) erregerseitig die Umlaufrichtung (5) der Mühlenfüllung (3) bestimmt, wird ihr durch die Linearschwingungen (4c) auf der dem Erreger (2) gegenüberliegenden Seite eine zusätzliche Beschleunigung erteilt, so daß die Umlaufgeschwindigkeit um ca. den Faktor 4 höher liegt als bei herkömmlichen, kreisschwingenden Schwingmühlen. Der Abstand der zur Achse des Mahlbehälters parallelen Achse des Erregers soll dazu größer sein als der kleinste Abstand vom Mahlbehältermittelpunkt zur Mahlbehälterinnenwand. Fig. 2 zeigt die Bewegungsverhältnisse, wenn der außerhalb der Schwerkraftachse und des Massenmittelpunktes einseitig links angeordnete Erreger (2) im Rechtslauf angetrieben wird. Unter diesen Bedingungen findet keine Umlaufbewegung (5) der Mühlenfüllung (3) statt, da die Aufwärtsbewegung (6) der Mühlenfüllung (3) in den Bereich der Linearschwingung (4c) fällt. Die Beanspruchung des Mahlgutes erfolgt in diesem Fall nur durch Stoß. Im Gegensatz dazu findet bei herkömmlichen, kreisschwingenden Schwingmühlen immer ein Umlauf der Mühlenfüllung statt und zwar entgegen der Arbeitsrichtung des Erregers, egal ob der Erreger im Rechts- oder Linkslauf angetrieben wird. If the exciter (2) rotates to the left, the the reference symbol (3) represents mill filling clockwise rotation (arrow 5). This leads the mill filling an upward movement on the exciter side (Arrow 6) and on the opposite side of the pathogen Side a downward movement (arrow 7) out. During the circular oscillation (4a) on the excitation side determines the direction of rotation (5) of the mill filling (3), the linear vibrations (4c) on the side opposite to the exciter (2) granted an additional acceleration, so that the Circulation speed about 4 times higher lies than with conventional, circular vibrating Vibrating mills. The distance from the axis of the grinding bowl parallel axis of the pathogen is supposed to do this be greater than the smallest distance from the center of the grinding container to the inside of the grinding container. Fig. 2 shows the movement conditions when the outside of the axis of gravity and the center of mass exciters (2) arranged on one side on the left Clockwise rotation is driven. Under these conditions there is no orbital movement (5) of the mill filling (3) instead, because the upward movement (6) of the mill filling (3) falls within the range of the linear vibration (4c). The In this case, the ground material is only subjected to stress by push. In contrast, conventional, circular vibrating mills are always in circulation Mill filling instead of against the working direction of the pathogen, regardless of whether the pathogen is legal or Left-hand rotation is driven.

    Gegenüber herkömmlichen Schwingmühlen ergeben sich folgende Vorteile:

    • Erhöhung des Auflockerungsgrades der Mühlenfüllung, so daß die bisherige maximale Aufgabekörnung mindestens um den Faktor 2 erhöht werden kann.
    • Verbesserung der Transportvorgänge durch hohe Umlaufgeschwindigkeiten der Mühlenfüllung und Homogenisierung der Mahlgutverteilung durch Aufhebung von Entmischungen.
    • Erhöhung des spezifischen Durchsatzes.
    • Verminderung des Energiebedarfs.
    • Aufhebung der energetisch bedingten oberen Grenze des Mahlrohrdurchmessers, der bisher bei 650 mm liegt.
    • Verringerung der Stillstandzeiten bei Reparaturen durch Wegfall von Übertragungselementen wie Wellen, Kupplungen u.a.
    • Ermöglichung der Modulbauweise durch Kopplung von Baueinheiten mit gleichem Mahlrohrdurchmesser zu Mühlen unterschiedlicher Länge für unterschiedliche Zerkleinerungsaufgaben und Verweilzeiten.
    The advantages compared to conventional vibratory mills are:
    • Increasing the degree of loosening of the mill filling so that the previous maximum feed size can be increased by at least a factor of 2.
    • Improvement of the transport processes through high circulation speeds of the mill filling and homogenization of the regrind distribution by eliminating segregation.
    • Increase specific throughput.
    • Reduction in energy consumption.
    • Elimination of the energy-related upper limit of the grinding tube diameter, which was previously 650 mm.
    • Reduction of downtimes for repairs by eliminating transmission elements such as shafts, couplings, etc.
    • Enabling the modular design by coupling units with the same grinding tube diameter to mills of different lengths for different shredding tasks and dwell times.

    Im folgenden werden schematisiert vier Ausführungsbeispiele der Erfindung für eine Exzenter-Schwingmühle mit einem Mahlrohrdurchmesser von 600 bis 1000 mm behandelt. Four exemplary embodiments are shown schematically below the invention for an eccentric vibratory mill with treated a grinding tube diameter of 600 to 1000 mm.

    Fig. 3 zeigt schematisiert die Ausführung einer Exzenter-Schwingmühle mit einem schwingungsfähig abgestützten Mahlbehälter in Form eines Mahlrohrs (1) von 600 mm Durchmesser, das einseitig außerhalb der Schwerkraftachse und des Massenmittelpunktes starr mit einem Unwuchtmotor als Erreger (2) verbunden ist. Der Ausgleich der Erregermasse erfolgt durch eine achsparallel auf der gegenüberliegenden Seite des Mahlrohres angeordnete Ausgleichsmasse (8).Fig. 3 shows schematically the design of an eccentric vibratory mill with a vibrationally supported Grinding container in the form of a grinding tube (1) of 600 mm Diameter that is unilaterally outside the gravity axis and the center of mass rigid with an unbalance motor is connected as an exciter (2). The pathogen mass is balanced by a axially parallel on the opposite side of the Compensating mass (8) arranged in the grinding tube.

    Gemäß Fig. 4 wird die gleiche Konstruktion wie in Fig. 3 dadurch erweitert, daß sich anstelle der Ausgleichsmasse (8) ein zweiter Unwuchtmotor (9) direkt am Mahlrohr (1) befindet. Die Schwingmühle kann wahlweise entweder durch den Erreger (2) oder durch den Erreger (9) betrieben werden, wobei jeweils der andere Unwuchtmotor (9 bzw. 2) als Ausgleichsmasse fungiert. Dies erlaubt die Betriebsweise der Mühle mit verschiedenen Erregerparametern wie Drehzahl und Schwingkreisdurchmesser.4, the same construction as in Fig. 3rd thereby expanded that instead of the balancing mass (8) a second unbalance motor (9) directly on Grinding tube (1) is located. The vibratory mill can be optionally either by the pathogen (2) or by the Exciter (9) are operated, each of the other unbalance motor (9 or 2) as a compensating mass acts. This allows the mill to operate with different excitation parameters such as speed and Resonant circuit diameter.

    Ein weiteres Beispiel der Erfindung ist in Fig. 5 dargestellt. Das Mahlrohr (1) hat in diesem Fall einen Durchmesser von 1000 mm und ist mit zwei übereinander, einseitig außerhalb der Schwerkraftachse und des Massenmittelpunktes angeordneten, synchron arbeitenden Unwuchtmotoren als Erreger (2a, 2b) ausgerüstet. Der Ausgleich der Erregermasse erfolgt wiederum durch eine Ausgleichsmasse (8) entsprechend Fig. 3. Another example of the invention is shown in FIG. 5 shown. The grinding tube (1) has in this case a diameter of 1000 mm and is with two one above the other, one-sided outside the gravity axis and the center of mass, synchronous unbalance motors as exciters (2a, 2b). The compensation of the pathogen mass takes place again by means of a balancing mass (8) corresponding to FIG. 3.

    Die Kopplung von Baueinheiten entsprechend Fig. 5 wird in Fig. 6 ausgewiesen. Zur Anpassung an unterschiedliche Mahlprobleme werden z.B. zwei Baueinheiten (A) und (B) zu einer Mühle zusammengefügt.The coupling of structural units according to FIG. 5 is shown in Fig. 6. To adapt to different grinding problems are e.g. two Units (A) and (B) put together to form a mill.

    Bei der in den Figuren 7 und 8 dargestellten Exzenter-Schwingmühle ist ein Mahlbehälter in Form eines Mahlrohres (1) mittels Schwingelementen (14) schwingungsfähig auf einem Grundrahmen (15) abgestützt. An dem Mahlrohr (1) ist rechts mittels einer Quertraverse (12) eine Erregereinheit in Form eines Unwuchtmotors (2) starr befestigt, wobei die Federnachse des antriebsseitigen Schwingelementes (14) zwischen den Schwerkraftachsen des Mahlbehälters 1 einerseits und der Erregereinheit 2 andererseits liegt.The one shown in FIGS. 7 and 8 Eccentric vibratory mill is a grinding vessel in shape a grinding tube (1) by means of vibrating elements (14) vibratable on a base frame (15) supported.
