Description

Walzenmühle  rolling mill
Die Erfindung betrifft eine Walzenmühle mit zwei in einem Maschinenrahmen angeordneten Walzeneinheiten, die jeweils eine in zwei Lagersteinen drehbar gelagerte Mahlwalze aufweisen, wobei die beiden Mahlwalzen gegenüberliegend angeordnet und mit jeweils einem Antrieb zum gegenläufigen Antreiben der Mahlwalzen gekoppelt sind. The invention relates to a roller mill with two arranged in a machine frame roller units, each having a rotatably mounted in two jewels bearing grinding roller, wherein the two grinding rollers are arranged opposite one another and each coupled to a drive for driving in opposite directions of the grinding rollers.
Zwischen Maschinenrahmen und wenigstens einer Walzeneinheit ist ein Kraftbeaufschlagungssystem zur Erzeugung einer Mahlkraft vorgesehen, wobei die Mahlkraft über den aus mehreren Rahmenteilen bestehenden Maschinenrahmen und die Lagersteine auf die Mahlwalzen übertragen wird. Dabei ist zwischen wenigstens zwei miteinander verbundenen Rahmenteilen und/oder zwischen einem Rahmenteil und einem der Lagersteine eine lösbare, formschlüssige Verbindung mit zwei gegeneinander gepressten Verbindungsflächen zur Übertragung der Mahlkraft vorgesehen ist. Between the machine frame and at least one roller unit, a Kraftbeaufschlagungssystem is provided for generating a grinding force, wherein the grinding force is transmitted via the machine frame consisting of several frame parts and the jewels on the grinding rollers. In this case, between at least two frame parts connected to one another and / or between a frame part and one of the bearing blocks, a detachable, positive connection with two mutually pressed connection surfaces for the transmission of the grinding force is provided.
Da die Mahlwalzen im Betrieb verschleißen, ist ein turnusmäßiger Walzenwechsel erforderlich, bei dem die Walzeneinheiten nach dem Lösen der Verbindung zwischen Mahlwalze und Antrieb aus dem Maschinenrahmen herausgezogen werden. Dieser Walzenwechsel ist bei Gutbettwalzenmühlen etwa 3 mal pro Jahr erforderlich und ist jeweils mit einem erheblichen Zeitaufwand verbunden, sodass Möglichkeiten gesucht wurden, wie sie beispielsweise in der DE 10 2010 048 214 AI offenbart sind, um den Walzenwechsel zu beschleunigen. Since the grinding rollers wear in operation, a regular roll change is required, in which the roller units are pulled out after the release of the connection between the grinding roller and drive from the machine frame. This roll change is required about 3 times a year in the case of high-grade roll mills and is associated with a considerable expenditure of time, so that possibilities were sought, as disclosed, for example, in DE 10 2010 048 214 A1 in order to accelerate the roll change.
Üblicherweise werden bei der Verbindung der Rahmenteile des Maschinenrahmens formschlüssige Verbindungen in Form von runden oder ebenen Passfederverbindungen oder auch Bolzenverbindungen eingesetzt. Bei der Demontage wird die Verbindung zwischen den Druckbalken und einem oberen Rahmenteil (der auch als Obergurt bezeichnet wird) und einem unteren Rahmenteil gelöst, sodass der obere Rahmenteil angehoben werden kann und die Druckbalken und die Walzeneinheit(en) herausgezogen werden können. Dieser Demontagevorgang ist nach wie vor aufwendig und zeitintensiv. Usually, in the connection of the frame parts of the machine frame positive connections in the form of round or flat feather key or bolt connections are used. When disassembling the connection between the pressure bar and an upper frame part (which is also referred to as top chord) and a lower frame part is released, so that the upper frame part can be raised and the pressure bar and the roller unit (s) can be pulled out. This disassembly process is still complex and time consuming.
Der Erfindung liegt daher die Aufgabe zugrunde, eine schnellere Demontage und Montage einer Walzeneinheit zu ermöglichen. The invention is therefore based on the object to enable a faster disassembly and assembly of a roller unit.
Erfindungsgemäß wird diese Aufgabe durch eine Walzenmühle mit zwei in einem Maschinenrahmen angeordneten Walzeneinheiten gelöst, die jeweils eine in zwei Lagersteinen drehbar gelagerte Mahlwalze aufweisen, wobei die beiden Mahlwalzen gegenüberliegend angeordnet und mit jeweils einem Antrieb zum gegenläufigen Antreiben der Mahlwalzen gekoppelt sind, zwischen Maschinenrahmen und wenigstens einer Walzeneinheit ein Kraftbeaufschlagungssystem zur Erzeugung einer Mahlkraft vorgesehen ist, wobei die Mahlkraft über den Maschinenrahmen und die Lagersteine auf die Mahlwalzen übertragen wird, und der Maschinenrahmen aus mehreren Rahmenteilen besteht, wobei zwischen wenigstens zwei miteinander verbundenen Rahmenteilen und/oder zwischen wenigstens einem Rahmenteil und einem der Lagersteine eine lösbare, formschlüssige Verbindung mit zwei gegeneinander gepressten Verbindungsfiächen zur Übertragung der Mahlkraft vorgesehen ist, wobei wenigstens eine der beiden gegeneinander gepressten Verbindungsfiächen eine mikroformschlusserzeugende Beschichtung aufweist. According to the invention this object is achieved by a roller mill with two arranged in a machine frame roller units, each having a rotatably mounted in two jewels grinding roller, the two grinding rollers are arranged opposite each other and coupled with a drive for driving the counter-rotating grinding rollers, between machine frame and at least a rolling unit is a Kraftbeaufschlagungssystem for generating a grinding force is provided, wherein the grinding force is transmitted to the grinding rollers via the machine frame and the bearing blocks, and the machine frame consists of several frame parts, wherein between at least two interconnected frame parts and / or between at least one frame part and a the stones a releasable, positive connection with two against each other pressed Verbindungsfiächen is provided for transmitting the grinding force, wherein at least one of the two Ver pressed against each other Bondingfiächen having a microforming-generating coating.
Die mikroformschlusserzeugende Beschichtung hat den Vorteil, dass die Verbindungsfiächen nur wenige Millimeter angehoben werden müssen, um das Herausziehen der Walzeneinheit zu ermöglichen. Durch die mikroformschlusserzeugende Beschichtung wird die übertragbare Kraft zwischen den beiden Verbindungsfiächen deutlich erhöht, sodass auch hohe Mahlkräfte, von beispielsweise 16000 kN und mehr, übertragen werden können, wie sie beispielsweise bei Gutbettwalzenmühlen bzw. Walzenpressen im Zement- und Mineralsbereich auftreten. The microforming coating has the advantage that the Verbindungsfiächen must be raised only a few millimeters to allow the withdrawal of the roller unit. The microforming-producing coating significantly increases the transmittable force between the two bonding surfaces, so that even high grinding forces of, for example, 16,000 kN and more can be transmitted, as they are For example, in the case of high-pressure roller mills or roller presses in the cement and mineral area occur.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unter anspräche. Further embodiments of the invention are the subject of the subclaims.
Gemäß einer weiteren Ausgestaltung der Erfindung sind Spannmittel, beispielsweise in Form einer Vielzahl von Schraub Verbindungen, vorgesehen, um die beiden Verbindungsflächen gegeneinander zu pressen. Die mikroformschlusserzeugende Beschichtung der miteinander verbundenen Rahmenteile und/oder von Rahmenteil und Lagerstein ist vorzugsweise so ausgebildet, dass die Verbindung durch Anheben der beiden Verbindungsflächen voneinander um maximal 4 mm vollständig aufgehoben ist. According to a further embodiment of the invention, clamping means, for example in the form of a plurality of screw connections, are provided in order to press the two connecting surfaces against one another. The microforming-producing coating of the interconnected frame parts and / or frame part and bearing block is preferably formed so that the connection by lifting the two connecting surfaces from each other by a maximum of 4 mm is completely eliminated.
Die Verbindungsflächen sind vorzugsweise plan ausgebildet und die mikroformschlusserzeugende Beschichtung kann insbesondere durch eine Hartstoff- Partikelbeschichtung gebildet werden, wobei die Hartstoffpartikel, vorzugsweise eine Härte nach Mohs von 6 bis 10 aufweisen. The connecting surfaces are preferably planar and the microforming-producing coating can be formed, in particular, by a hard-particle coating, the hard-material particles preferably having a Mohs hardness of from 6 to 10.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Walzemühle so ausgebildet, dass eine Walzeneinheit als Loswalze und die andere Walzeneinheit als Festwalze im Maschinenrahmen gehaltert ist, wobei das Kraftbeaufschlagungssystem zwischen Maschinenrahmen und der als Loswalze fungierenden Walzeneinheit angeordnet ist. According to a preferred embodiment of the invention, the roll mill is designed so that a roller unit is mounted as a Loswalze and the other roller unit as a fixed roller in the machine frame, wherein the Kraftbeaufschlagungssystem between the machine frame and acting as the Loswalze roller unit is arranged.
Der Maschinenrahmen wird vorzugsweise durch wenigstens einen unteren Rahmenteil, wenigstens einen oberen Rahmenteil und mehrere den oberen und unteren Rahmenteil verbindende Druckbalken gebildet. Dabei können die Lagersteine am oberen und unteren Rahmenteil gleitverschieblich geführt sein. Die Verbindungsflächen sind entweder an Teilen des Maschinenrahmens ausgebildet oder die mikroformschlusserzeugende Beschichtung ist auf einem Zwischenelement aufgebracht, das fest mit den zu verbindenden Teilen des Maschinenrahmens verbunden ist. Gemäß einer ersten bevorzugten Ausgestaltung der Walzenmühle sind vier Druckbalken vorgesehen, wobei zwei Druckbalken als Widerlager der einen Walzeneinheit und die beiden anderen Druckbalken als Widerlager der anderen Walzeneinheit dienen und der obere und untere Rahmenteil mit den vier Druckbalken durch jeweils eine lösbare, formschlüssige Verbindung mit zwei gegeneinander gepressten Verbindungsflächen verbunden sind, wobei wenigstens zwei der gegeneinander gepressten Verbindungsflächen die mikroformschlusserzeugende Beschichtung aufweisen. The machine frame is preferably formed by at least one lower frame part, at least one upper frame part and a plurality of pressure bars connecting the upper and lower frame parts. In this case, the jewels can be slidably guided on the upper and lower frame part. The connecting surfaces are either formed on parts of the machine frame or the microformschlusserzeugende coating is applied to an intermediate member which is fixedly connected to the parts to be joined of the machine frame. According to a first preferred embodiment of the roller mill four pressure bars are provided, wherein two pressure bars serve as an abutment of a roller unit and the other two pressure bars as abutments of the other roller unit and the upper and lower frame part with the four pressure bars by a releasable, positive connection with two are pressed against each other pressed connecting surfaces, wherein at least two of the pressed against each other connecting surfaces have the microformschlusserzeugende coating.
Gemäß einer zweiten Ausgestaltung der Erfindung sind lediglich zwei Druckbalken vorgesehen, die mit den oberen und den unteren Rahmenteilen verbunden sind und als Widerlager der als Loswalze fungierende Walzeneinheit dienen. Die als Festwalze fungierende Walzeneinheit ist dann über ihre Lagersteine mit den oberen und unteren Rahmenteilen über die lösbare, formschlüssige Verbindung mit zwei gegeneinander gepressten Verbindungsflächen verbunden, wobei wiederum wenigstens eine der beiden gegeneinander gepressten Verbindungsflächen die mikroformschlusserzeugende Beschichtung aufweist. According to a second embodiment of the invention, only two pressure bars are provided, which are connected to the upper and the lower frame parts and serve as an abutment of acting as a Loswalze roller unit. The roller unit acting as a fixed roller is then connected via its bearing blocks with the upper and lower frame parts via the detachable, positive connection with two mutually pressed connection surfaces, wherein in turn at least one of the two pressed against each other connecting surfaces has the microforming-generating coating.

The disassembly of a roller unit will be apparent from Figures 6 to 8. FIG. 6 shows the roller mill in its operating position according to FIG. 1. In a first step, the screw connections 6, 7 are released between the two pressure bars 15, 17 and the associated lower and upper frame parts. Furthermore, the coupling of the roller unit to be replaced must be released from its drive. In Fig. 2, this coupling point is provided with the reference numeral 40. In order to facilitate the extraction of the pressure bars 15, 17 and the roller unit 2, guide rails 18, 19 are provided in extension of the lower frame parts 10, 11.
Nach dem Lösen der Schraub Verbindungen 6, 7 können die beiden Druckbalken 15, 17 über die Führungsschienen 18, 19 herausgezogen werden. Unter Umständen ist es zweckmäßig, wenn die beiden oberen Rahmenteile 12, 13 zu diesem Zweck mittels eines Kettenzuges um wenige Millimeter angehoben oder zumindest festgehalten werden. In der weiteren Folge wird dann auch die Walzeneinheit 2 vollständig herausgezogen. Sofern erforderlich wird dann auch die andere Walzeneinheit 3 nach Lösen ihrer Verbindung mit dem Antrieb 5 herausgezogen. Der Einbau erfolgt in umgekehrter Reihenfolge. In Fig. 9 ist eine Walzenmühle gemäß einem zweiten Ausführungsbeispiel dargestellt, die sich vom ersten Ausführungsbeispiel lediglich dadurch unterscheidet, dass die Druckbalken 15, 17 weggelassen wurden und die Lagersteine 22, 23 direkt mit dem unteren und oberen Rahmenteile 10, 12 bzw. 11, 13 verschraubt sind. After loosening the screw connections 6, 7, the two pressure bars 15, 17 can be pulled out via the guide rails 18, 19. Under certain circumstances, it is expedient if the two upper frame parts 12, 13 are raised for this purpose by a few millimeters by means of a chain hoist or at least held. In the further sequence, the roller unit 2 is then completely pulled out. If necessary, then the other roller unit 3 is pulled out after releasing their connection to the drive 5. Installation is the reverse order. 9 shows a roller mill according to a second embodiment, which differs from the first embodiment only in that the pressure bars 15, 17 have been omitted and the bearing blocks 22, 23 directly with the lower and upper frame parts 10, 12 and 11, 13 are bolted.
Die miteinander in Verbindung stehenden Bereiche der ersten und zweiten Verbindungsfläche sind vorzugsweise zu wenigstens 50%, höchstvorzugsweise zu wenigstens 90%>, mit der mikroformschlusserzeugenden Beschichtung bedeckt. Die einzelnen Partikel der Beschichtung weisen vorzugsweise eine längste Ausdehnung von durchschnittlich < 2 mm auf. Die Beschichtung kann wahlweise durch Klebung, Sintern, Lackierung, chemische Verfahren, galvanische Verfahren, Suspension oder Flammspritzverfahren aufgebracht werden. Es ist auch denkbar, dass die mikroformschlusserzeugende Beschichtung nicht direkt auf den Druckbalken bzw. den unteren oder oberen Rahmenteilen, sondern vielmehr auf Zwischenelementen aufgebracht ist, die jeweils fest mit den Druckbalken oder Rahmenteilen verbunden sind. The communicating portions of the first and second bonding surfaces are preferably at least 50%, most preferably at least 90%, covered with the microforming coating. The individual particles of the coating preferably have a longest extent of on average <2 mm. The coating can optionally be applied by gluing, sintering, painting, chemical processes, electroplating, suspension or flame spraying. It is also conceivable that the microforming-producing coating is not applied directly to the pressure bar or the lower or upper frame parts, but rather to intermediate elements which are each firmly connected to the pressure bars or frame parts.
Der große Vorteil der mikroformschlusserzeugenden Beschichtung besteht vor allem darin, dass bereits ein geringfügiges Abheben der beiden Verbindungsflächen von wenigen Millimetern völlig ausreichend ist, um die Druckbalken bzw. die Walzeneinheiten herauszuziehen. Dennoch gewährleistet diese Beschichtung eine ausreichende Übertragung der Mahlkräfte über den Maschinenrahmen. Des Weiteren ist der Fertigungsaufwand durch den Wegfall der bisher üblichen Passverbindungen wesentlich geringer und es ergibt sich eine kompaktere Bauform. Auch die Montage des Maschinenrahmens wird durch den geringeren Ausrichtungsaufwand erleichtert, da insbesondere keine Passkeilanfertigung auf der Baustelle erforderlich ist. The great advantage of the microforming-producing coating is, above all, that even a slight lifting off of the two connecting surfaces of a few millimeters is completely sufficient to pull out the pressure bars or the roller units. Nevertheless, this coating ensures adequate transfer of grinding forces across the machine frame. Furthermore, the production costs by the elimination of the usual passport joints is much lower and it results in a more compact design. The assembly of the machine frame is facilitated by the lower alignment effort, since in particular no Passkeilanfertigung on the site is required.
