Die Erfindung betrifft eine Rollenpresse zur Druckbehandlung insbesondere zur Gutbettzerkleinerung oder Kompaktierung bzw. Brikettierung körnigen Gutes, mit zwei in Lagergehäusen drehbar gelagerten gegenläufig angetriebenen und durch einen Walzenspalt voneinander getrennten Walzen, wobei die Lagergehäuse mit Ihren Unter- und Oberseiten auf Gleitbahnen von Konsolen des Maschinenrahmens gelagert sind, mit Einsatz von Hydraulikzylindern zum Anpressen der einen Walze über das im Walzenspalt befindliche Gut gegen die gegenüberliegende Walze.The invention relates to a roller press for pressure treatment in particular for Gutbettzerkleinerung or compaction or briquetting granular material, with two rotatably mounted in bearing housings counter-driven and separated by a nip rollers, the bearing housing stored with your lower and upper sides on slides of consoles of the machine frame are, with the use of hydraulic cylinders for pressing the one roller over the material located in the nip against the opposite roller.

Bei Walzenmühlen zur Durchführung der sogenannten Gutbettzerkleinerung werden die einzelnen Stücke bzw. Partikel des durch Reibung in den Walzenspalt eingezogenen Mahlgutes wie z. B. Zementrohmaterial, Zementklinker, Erze oder dergleichen in einem Gutbett, d. h. in einer zwischen den beiden Walzenoberflächen zusammengedrückten Materialschüttung bei Anwendung eines hohen Druckes ge- presst und gegenseitig zerkleinert, wobei man statt von einer Walzenmühle auch von einer Walzenpresse oder Rollenpresse spricht. Bei solchen bekannten Rollenpressen, siehe z. B. Broschüre "Rollen- pressen" Nr. 2-30Od der KHD Humboldt Wedag AG vom September 1994 oder z. B. WO 2005/070549 A1 , ist eine der beiden Walzen als Festwalze ausgebildet, die sich über Ihre Lagergehäuse gegen Endstücke des Maschinenrahmens abstützt, während sich die andere Walze als Loswalze über deren Lagergehäuse an Hydraulikzylindern abstützt, mit denen die Walzenpresskraft aufgebracht wird. KHD Humboldt Wedag GmbH 13.07.2007In roll mills for performing the so-called Gutbettzerkleinerung the individual pieces or particles of the drawn by friction in the nip grinding material such. For example, cement raw material, cement clinker, ores or the like in a bed of material, ie pressed in a compressed between the two roll surfaces bulk material when using a high pressure and crushed each other, which is instead of a roll mill also by a roll press or roller press. In such known roller presses, see, for. B. brochure "Rollenpressen" No. 2-30Od of the KHD Humboldt Wedag AG from September 1994 or z. As WO 2005/070549 A1, one of the two rollers is designed as a fixed roller, which is supported via their bearing housing against end pieces of the machine frame, while the other roller is supported as a Loswalze on the bearing housing to hydraulic cylinders, with which the roll pressing force is applied.

Beim Betrieb derartiger Rollenpressen sind die Oberflächen der Walzen aufgrund der hohen Pressdrücke und Presskräfte einer hohen Verschleißbeanspruchung ausgesetzt, besonders dann, wenn die Loswalze je nach Gutmaterialzufuhr zum Walzenspalt seitliche Ausweichbewegungen macht, wobei sich dann aufgrund der feststehenden Festwalze auch die Mittellage des Walzenspaltes und der aus diesem unten austretenden gepressten Gutmaterialschülpe ändert. Die Ausweichbewegung der Loswalze ist besonders dann groß, stoß- artig und für den Oberflächenyerschleiß der Walzen sowie für den Betrieb der Rollenpresse abträglich, wenn in den Walzenspalt ein un- zerkleinerbarer Fremdkörper, z. B. ein verlorener Hammer eines vorgeschalteten Hammerbrechers gerät.In the operation of such roller presses, the surfaces of the rollers are exposed to high wear stress due to the high compression pressures and pressing forces, especially if the Loswalze makes depending on Gutmaterialzufuhr to nip lateral evasive movements, which then due to the fixed fixed roller and the center position of the nip and this pressed out Gutgutschülpe exiting below changes. The evasive movement of the idler roller is particularly large, jerky and detrimental to the Oberflächenyerschleiß the rollers and for the operation of the roller press when in the nip an immiscible foreign body, eg. B. a lost hammer of an upstream hammer crusher device.

Aus der DE 19 27 164 C3 ist eine Doppelschwingenwalzenmühle bekannt, bei der die beiden Walzen jeweils in Schwingenarmen gelagert sind, die mit ihren unteren Enden am Maschinenrahmen angelenkt sind, so dass beide Walzen Ausweichwalzen sind. Jedoch ist das Prinzip der Doppelschwingenwalzenmühle bisher nur für Walzenmüh- len realisiert worden, nicht für Gutbettzerkleinerungs-Rollenpressen, bei denen die Walzenpresskräfte etwa um eine Zehnerpotenz höher liegen müssen als bei Walzenmühlen, z. B. bei 8 t/cm Walzenlänge und höher. Infolge der vergleichsweise niedrigen Walzendrücke und Walzenpresskräfte treten bei Walzenmühlen gravierende Probleme eines Walzenoberflächenverschleißes nicht auf. Abgesehen von der enormen Gewichtsbelastung durch die schwergewichtigen Walzen belastet eine stoßartige Änderung der Walzenspaltweite z. B. anlässlich eines Fremdkörperdurchganges bei der Doppelschwingenwalzenmühle zusätzlich die Schwingenlagerungsgelenke, die daher be- sonders massiv und schwergewichtig ausgeführt sein müssen. KHD Humboldt Wedag GmbH 13.07.2007From DE 19 27 164 C3 a double swing roller mill is known, in which the two rollers are each mounted in swing arms, which are articulated with their lower ends on the machine frame, so that both rollers are Ausweichwalzen. However, the principle of Doppelschwingenwalzenmühle has been realized len only for Walzenmüh- len, not for Gutbettzerkleinerungs roller presses, in which the roll compression forces must be about one order of magnitude higher than in roll mills, z. B. at 8 t / cm roll length and higher. Due to the comparatively low roller pressures and roller press forces, serious problems of roller surface wear do not occur in roller mills. Apart from the enormous weight load by the heavyweight rollers loaded a jerky change in the nip width z. B. on the occasion of a foreign body passage in the double rocker roller mill in addition the swing bearing joints, which must therefore be carried out particularly massive and heavy weight.

Der Erfindung liegt die Aufgabe zugrunde, eine Rollenpresse insbesondere zur Gutbettzerkleinerung zu schaffen, mit einem an sich konventionellen Maschinenrahmen mit Konsolen-Gleitbahnen zur Auflagerung der Walzen-Lagergehäuse, wobei aufgrund der Maschinen- konstruktion die Oberflächenbeanspruchung der Walzen vermindert und die Walzenstandzeit erhöht sind.The invention has for its object to provide a roller press, in particular for Gutbettzerkleinerung, with a per se conventional machine frame with console slideways for bearing the roller bearing housings, which reduced due to the machine construction, the surface stress of the rollers and the roller life are increased.

Diese Aufgabe wird gemäß der Erfindung mit einer Rollenpresse mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved according to the invention with a roller press with the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Bei der erfindungsgemäßen Rollenpresse ist nicht wie bisher üblich die eine Walze als Festwalze über ihre Lagergehäuse starr an Seitenteilen des Maschinenrahmens abgestützt, während die andere Walze als Loswalze über ein Hydrauliksystem federnd ausweichbar abgestützt ist, sondern erfindungsgemäß sind beide Walzen als quer zum Walzenspalt bewegliche Loswalzen ausgebildet, deren Lagergehäuse über den Walzenpressdruck aufzubringende Hydraulikzylinder an Seitenteilen des Maschinenrahmens abgestützt sind. Das heißt, bei der erfindungsgemäßen Rollenpresse ist die Losrollenseitenhälfte in der Maschinenmitte praktisch komplett gespiegelt. Bei dieser Maschinenkonstruktion weichen beide Loswalzen bei sich ändernder Presss- chülpendicke und z. B. bei einem Fremdkörperdurchgang durch den Walzenspalt immer spiegelsymmetrisch zum ursprünglichen Walzen- spalt aus. Die Walzenausweichbewegungen und Wege und die dabei auftretenden Beschleunigungen sowie auch evtl. auftretende Walzenschiefstellungen vermindern sich pro Loswalze im Vergleich zum konventionellen Rollenpressensystem bis zur Hälfte.In the roller press according to the invention is not as previously customary one roller supported as a fixed roller on its bearing housing rigidly on side parts of the machine frame, while the other roller is resiliently supported as Losdreze via a hydraulic system, but according to the invention both rollers are designed as transverse to the nip movable Loswalzen whose bearing housings are to be applied via the roll pressure hydraulic cylinder to be applied to side parts of the machine frame. That is, in the roller press according to the invention, the Losrollenseitenhälfte is almost completely mirrored in the middle of the machine. In this machine design, both idler rolls yield to changing thickness of the compacting die and z. B. in a foreign body passage through the nip always mirror symmetry to the original roll gap. The roller evasive movements and paths and the accelerations occurring as well as any occurring roll misalignments are reduced by up to half per loose roller compared to the conventional roller press system.

Um bei der erfindungsgemäßen Rollenpresse die Ausweichbewegun- gen der beiden Loswalzen nicht zu behindern, sollen die Reibungskräfte zwischen den Lagergehäusen und den Gleitbahnen der Maschinenkonsolen so gering wie möglich sein.In order not to obstruct the evasive movements of the two idler rollers in the roller press according to the invention, the frictional forces between the bearing housings and the slide tracks of the machine consoles should be as small as possible.

Nach einem weiteren Merkmal der Erfindung sind sämtliche Hydrau- likzylinder der beiden Loswalzen so mit Drucköl beaufschlagt, dass sich beide Loswalzen gleichmäßig symmetrisch zur Maschinenmitte hin spiegelbildlich zu dieser bewegen. Dazu können die Druckölräu- me sämtlicher Hydraulikzylinder über einen Ölvolumenstromteiler mit einem Stickstoffgasspeicher so verbunden sein, dass beide Loswal- zen zum Walzenspalt hin zentriert sind. Es besteht aber auch die Möglichkeit, die Lageänderung der beiden Loswalzen zu messen und über die Messwerte der Loswalzenpositionen die Druckölbeaufschla- gung der einzelnen Hydraulikzylinder nachzuregeln.According to a further feature of the invention, all of the hydraulic cylinders of the two idler rollers are subjected to pressure oil in such a way that both idler rollers move symmetrically symmetrically with respect to the machine center in mirror image to the latter. For this purpose, the pressure oil chambers of all the hydraulic cylinders can be connected via an oil volume flow divider to a nitrogen gas storage so that both loose rolls are centered towards the nip. However, it is also possible to measure the change in position of the two idler rollers and readjust the pressure oil supply of the individual hydraulic cylinders via the measured values of the idler roller positions.

Bei der erfindungsgemäßen Rollenpresse kann der Walzenwechsel vereinfacht werden, wenn wenigstens eines der beiden Seitenteile am Maschinenrahmen angelenkt und zum Walzenwechsel zur Seite hin ausklappbar ist. Dann können die Hydraulikzylinder mit Vorteil so an dem jeweiligen ausklappbaren Seitenteil des Maschinenrahmens be- festigt sein, dass die jeweilige Walze samt Lagergehäusen über die ausgeklappten Hydraulikzylinder hinweg über das Seitenteil aus- und einbaubar ist.In the roller press according to the invention, the roll change can be simplified if at least one of the two side parts articulated on the machine frame and the roll change to the side is folded out. Then the hydraulic cylinders can advantageously be fastened to the respective fold-out side part of the machine frame in such a way that the respective roller together with the bearing housings can be removed and installed via the folded-out hydraulic cylinder via the side part.
