Description

Die Erfindung betrifft einen Walzenbrecher zum Brechen von heißem Schüttgut wie z. B. von aus einem Brennofen ausgetragenen Zementklinker, mit wenigstens zwei zueinander parallel angeordneten gegenläufig angetriebenen Brechwalzen, die ein drehbar gelagertes Tragrohr aufweisen, auf das jeweils eine Vielzahl mit dem Tragrohr drehfest zu verbindender Brechringe aufschiebbar ist, deren Außenoberflächen Brechelemente aufweisen.The invention relates to a roll crusher for breaking hot bulk material such. B. of discharged from a kiln cement clinker, with at least two mutually parallel oppositely driven crushing rollers having a rotatably mounted support tube, on each of which a plurality of the support tube rotatably connected to crushing rings can be pushed, the outer surfaces have refractive elements.

Bei einer Zementklinkerproduktionslinie wird der in einem Drehrohrofen aus calciniertem Zementrohmehl erbrannte glühend heiße Zementklinker aus dem Ofenaustragsende auf einen Kühler, heute meistens auf den Kühlrost eines Rostkühlers abgeworfen, auf diesem verteilt und durch geeignete Fördertechnologien in Längsrichtung zum Kühleraustragsende bewegt, wobei gleichzeitig der Kühlrost und die heiße Schüttgutschicht quer zur Förderrichtung im wesentlichen von unten nach oben von Kühlluftdurchströmungen durchsetzt werden. Dabei hat es sich als vorteilhaft herausgestellt, wenn der zum Zusammenbacken neigende heiße Zementklinker eine möglichst gleichmäßige Stückgröße und gleichmäßige Korngrößenverteilung aufweist. Daher ist es bereits bekannt, bei einem Rostkühler im Bereich einer Kühlroststufe als sogenannten Zwischenbrecher einen Walzenbrecher mit mehreren parallel angeordneten gegenläufig rotierbaren Brechwalzen anzuordnen, die sich über die gesamte Breite des Rostkühlers erstrecken und welche die Aufgabe haben, insbesondere die großen Klinkerstücke zu zerkleinern, die sich dann nach Durchgang durch die Walzenspalte im anschließenden Rostkühlerbereich weiter abkühlen lassen, siehe z. B. Broschüre 7-330e der KHD Humboldt Wedag AG vom Oktober 1994, Seite 4 . Auch am Klinkeraustragsende eines Rostkühlers im Gutauslaufschacht angeordnete Klinkerbrecher in Gestalt derartiger Mehrwalzenbrecher sind bekannt.In a cement clinker production line burned in a rotary kiln of calcined cement raw meal burnt hot cement clinker from the Ofenaustragsende on a radiator, today mostly on the cooling rack of a grate cooler, distributed on this and moved by suitable conveyor technologies in the longitudinal direction to Kühleraustragsende, at the same time the cooling grid and the hot bulk material layer are traversed transversely to the conveying direction substantially from bottom to top of cooling air flow. It has been found to be advantageous if the tendency to cake hot cement clinker as uniform as possible piece size and uniform particle size distribution. Therefore, it is already known to arrange a roll crusher with a plurality of parallel oppositely rotatable crushing rollers, which extend over the entire width of the grate cooler and which have the task of crushing in particular the large clinker pieces, the then after Allow passage through the nips in the subsequent grate cooler area to cool further, see, for example, US Pat. B. Brochure 7-330e of the KHD Humboldt Wedag AG from October 1994, page 4 , Also on Klinkeraustragsende a grate cooler in the Gutauslaufschacht arranged clinker breakers in the form of such Mehrwalzenbrecher are known.

Bei solchen Walzenbrechern zum Brechen von heißem Zementklinker sind die Walzenoberflächen hohen mechanischen und thermischen Beanspruchungen ausgesetzt. Es ist daher z. B. aus der EP 1 495 812 A1 ein am Gutaustragsende eines Zementklinker-Rostkühlers angeordneter Mehrwalzenbrecher bekannt, deren mehrere zueinander parallel angeordnete gegenläufig angetriebene Brechwalzen jeweils eine drehbar gelagerte Tragrohrkonstruktion aufweisen, die eine angetriebene Welle darstellt, auf die jeweils mehrere mit der Welle drehfest zu verbindende und an ihrer Außenoberfläche Brechelemente aufweisende Brechringe aufschiebbar sind, so dass im Verschleißfalle die einzelnen aufgeschobenen Brechringe einfach austauschbar sind. Bei den bekannten Brechringen sind die voneinander beabstandeten Brechelemente allerdings ausschließlich als achsparallele. Profile und im übrigen in ihrer Gesamtheit ungleichmäßig über den Außenumfang der Brechringe verteilt, wodurch sich der Walzenspalt zwischen benachbarten Brechwalzen während des Brechwalzenbetriebes ständig verengt und dann wieder erweitert, was je nach Drehwinkelstellung der Brechwalzen eine ungleichmäßige Zerkleinerung des Zementklinkers und eine ungleichmäßige Korngrößenverteilung des den Mehrwalzenbrecher verlassenden Austragsgutes zur Folge hat, mit der weiteren Folge, dass im Mehrwalzenbrecher nicht ausreichend aufgeschlossene Klinkerstücke auch nicht ausreichend gekühlt werden können. Darüber hinaus beeinflusst ein variierendes Kornband des Zementklinkers die nachgeschaltete Mahlung negativ.In such roll crushers for breaking hot cement clinker, the roll surfaces are exposed to high mechanical and thermal stresses. It is therefore z. B. from the EP 1 495 812 A1 a arranged at the Gutaustragsende a cement clinker grate cooler multi-roll crusher, having a plurality of mutually parallel oppositely driven crushing rollers each having a rotatably mounted support tube construction, which represents a driven shaft, on each of a plurality of rotatably connected to the shaft and on its outer surface refractive elements having crushing rings pushed are so that in case of wear, the individual pushed crushing rings are easily interchangeable. In the known crushing rings, however, the spaced refractive elements are exclusively as axially parallel. Profiles and the rest in their entirety unevenly distributed over the outer circumference of the crushing rings, whereby the nip between adjacent crushing rollers during crushing operation constantly narrows and then widened, which depending on the angular position of the crushing rollers uneven crushing of the cement clinker and uneven particle size distribution of the multi-roll crusher leaving the product to be discharged, with the further consequence that in the multi-roll crusher insufficiently digested clinker pieces can not be sufficiently cooled. In addition, a varying grain size of the cement clinker negatively affects the downstream grinding.

Aus der US-A-3 120 354 ist ein Walzenbrecher bekannt, dessen Brechwalze über die Aussenseite von Brechringen über Umfang und Breite gleichmässig verteilt angeordnete Brechelemente aufweist.From the US-A-3,120,354 a roll crusher is known, the crushing roller on the outside of crushing rings over the circumference and width uniformly distributed arranged crushing elements.

Der Erfindung liegt die Aufgabe zugrunde, für einen Rostkühler zum Kühlen von heißem Schüttgut insbesondere heißem Zementlinker einen Mehrwalzenbrecher der eingangs genannten Art zu schaffen, der geeignet ist, bei gutem Guteinzugsverhalten und hoher Standzeit der ringförmigen Brechwerkzeuge die vom Drehrohrofen ausgetragenen Zementklinkerbrocken auf einigermaßen gleiche Stückgrößen zu zerkleinern und eine gleichmäßige Korngrößenverteilung im aufgeschlossenen Kühlgut als Voraussetzung für einen hohen Kühlerwirkungsgrad und für eine gleichmäßigere nachgeschaltete Mahlung zu erzielen.The invention has for its object to provide a multi-roll crusher of the type mentioned for a grate cooler for cooling hot bulk material in particular hot cement linker, which is suitable for good Guteinzugsverhalten and long service life of the annular crushing tools discharged from the rotary kiln cement clinker dry to reasonably equal piece sizes crushing and to achieve a uniform particle size distribution in the digested refrigerated goods as a prerequisite for a high cooler efficiency and for a more uniform downstream grinding.

Diese Aufgabe wird gemäß der Erfindung mit einem Walzenbrecher mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with a roll crusher having the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Dadurch, dass beim erfindungsgemäßen einem Klinkerkühler zugeordneten Walzenbrecher als Brechwerkzeuge dienende auswechselbare Brechringe eingesetzt werden, von deren zylindrischer Außenseite Brechelemente vorspringen, die sowohl über den Umfang als auch über die Breite der Brechringkörper gleichmäßig verteilt bzw. gleichmäßig voneinander beabstandet angeordnet sind, werden die Aufgabegutmaterialien für die Brechwalzen einschließlich der in der heißen Klinkerschicht enthaltenen Glühnester von den Brechelementen der rotierenden Brechwalzen gleichmäßig aufgeschlossen, was eine gleichmäßige Korngrößenverteilung im Brecheraustragsgut und damit eine effektive Klinkerkühlung zur Folge hat. Außerdem vermitteln die gleichmäßig über die zylindrische Außenseite der Brechringkörper verteilt angeordneten vorspringenden Brechelemente die Funktion auswechselbarer Einzugshilfen für das zu brechende Gut in den jeweiligen Walzenspalt.Due to the fact that interchangeable crushing rings serving as crushers are used in the roller crushers associated with a clinker cooler according to the invention, and from the cylindrical outer side of which project breakers which are evenly distributed over the circumference and across the width of the crushing rings are evenly spaced, the feed materials for the crushing rollers including the Glühnester contained in the hot clinker layer of the crushing elements of the rotating crushing rollers uniformly digested, which has a uniform particle size distribution in Brecheraustragsgut and thus an effective clinker cooling result. In addition, the evenly distributed over the cylindrical outer side of the crushing ring arranged arranged breaking elements convey the function interchangeable catchment aids for the material to be crushed in the respective nip.

Erfindungsgemäss ist der Werkstoff der vorspringenden Brechelemente verschleißbeständiger als der Werkstoff des insbesondere aus Metallguss bestehenden Brechringkörpers, der die Brechelemente trägt. So kann der Werkstoff der Brechelemente z. B. aus Hartmetall bestehen, z. B. aus Sinterhartmetall. Die kompletten Brechringe mit den vorspringenden Brechelementen können durch Verbundguss oder durch Aufschweißung der harten Brechelemente auf die Brechringkörper oder durch Einsetzen der harten Brechelemente in entsprechende Ausnehmungen wie Bohrungen, Nuten etc. der Brechringkörper hergestellt sein.According to the invention, the material of the protruding crushing elements is more resistant to wear than the material of the crushing body, which consists in particular of cast metal, and which carries the crushing elements. Thus, the material of the refractive elements z. B. made of carbide, z. B. of cemented carbide. The complete crushing rings with the projecting crushing elements can be produced by composite casting or by welding the hard crushing elements on the crushing rings or by inserting the hard crushing elements into corresponding recesses such as holes, grooves, etc. of the crushing rings.

Nach einem weiteren Merkmal der Erfindung können die von der zylindrischen Außenseite der Brechringkörper vorspringenden Brechelemente die Gestalt von Noppen haben, z. B. zylindrische Noppen, kegelförmige Noppen, Vielecknoppen etc.. Alternativ dazu können die Brechelemente aber auch die Gestalt von parallel zur Brechringachse liegenden Stegen haben.According to a further feature of the invention, the projecting from the cylindrical outer side of the crushing ring crushing elements may have the shape of nubs, z. As cylindrical studs, conical nubs, polygons, etc. Alternatively, the refractive elements but also have the shape of lying parallel to the Brechringachse webs.

Die Erfindung und deren weitere Merkmale und Vorteile werden anhand der in den Figuren schematisch dargestellten Ausführungsbeispiele näher erläutert.The invention and its further features and advantages will be explained in more detail with reference to the embodiments schematically illustrated in the figures.

Beim erfindungsgemäßen Walzenbrecher, der einem Zementklinkerkühler zugeordnet ist, sind mehrere Brechwalzen, z. B. 5 oder 6 Brechwalzen parallel nebeneinander angeordnet, die sich über die gesamte Kühlerbreite quer zur Kühlerförderrichtung erstrecken und die in ihrer Mehrzahl gegenläufig angetrieben sind. Dabei weisen die Brechwalzen jeweils ein in der Zeichnung nicht dargestelltes drehbar gelagertes Tragrohr auf, auf das jeweils mehrere mit dem Tragrohr drehfest zu verbindende Brechringe aufschiebbar sind, deren Außenoberfläche vorspringende Brechelemente aufweist. Das heißt auf das Tragrohr jeder der parallel nebeneinander angeordneten Brechwalzen ist jeweils eine Vielzahl von Brechringen auswechselbar aufgeschoben, von denen in Figur 1 der Brechring 10 dargestellt ist, der, wie auch die übrigen Brechringe, über an der Innenseite angeordnete Nuten 11 drehfest mit dem nicht dargestellten Tragrohr zu verbinden ist.When roll crusher according to the invention, which is associated with a cement clinker cooler, several crushing rollers, z. B. 5 or 6 crushing rollers arranged side by side in parallel, which extend across the entire radiator width transverse to the radiator conveying direction and which are driven in opposite directions in their majority. In this case, the crushing rollers each have a non-illustrated in the drawing rotatably mounted support tube, on each of which a plurality of break-in rings to be connected to the support tube to be connected are pushed, the outer surface having projecting refractive elements. That is, on the support tube of each of the parallel juxtaposed crushing rollers a plurality of crushing rings is interchangeably postponed, of which in FIG. 1 the crushing ring 10 is shown, which, like the other breaking rings, is non-rotatably connected to the support tube, not shown, via grooves 11 arranged on the inside.

Die Außenseite des Brechrings 10 sowie sämtlicher auf das zugehörige mit Drehantrieb versehene Tragrohr aufgeschobenen Brechringe ist zylindrisch. Wie aus der perspektivischen Darstellung der Figur 1 klar hervorgeht, springen von der zylindrischen Außenseite des Brechrings 10 Brechelemente in Gestalt von beispielsweise zylindrischen Noppen 12 vor, die sowohl über den Umfang als auch über die Breite des Brechrings 10 gleichmäßig verteilt angeordnet sind. Diese gleichmäßige Verteilung bzw. Beabstandung der Vielzahl der nach Art eines Rasters angeordneten Brechelement-Noppen 12 gilt für sämtliche auf jeweils ein Tragrohr aufgeschobenen und dann unmittelbar nebeneinander angeordneten Brechringe 10, so dass ein Paar zueinander parallel angeordneter gegenläufig angetriebener Brechwalzen, ausgestattet mit dem gleichmäßig verteilt angeordneten Feld von Brechelement-Noppen 12 ein gutes Guteinzugsverhalten aufweist, das heißt auch in der Lage ist, im Schüttgutbett des heißen Zementklinkers enthaltene Glühnester wirkungsvoll aufzuschließen und ein Brechgut mit gleichmäßiger Korngrößenverteilung zu erzeugen, wodurch der Kühlwirkungsgrad bei der Abkühlung des Zementklinkers erhöht sowie die nachfolgende Mahlung des Zementklinkers vergleichmäßigt wird.The outer side of the crushing ring 10 as well as all the crushing rings pushed onto the associated rotary support tube are cylindrical. As seen from the perspective view of FIG. 1 clearly shows jumping from the cylindrical outer side of the crushing ring 10 before breaking elements in the form of, for example, cylindrical nubs 12, which are arranged distributed uniformly over both the circumference and over the width of the crushing ring 10. This uniform distribution or spacing of the plurality of arranged in the manner of a grid crushing element nubs 12 applies to all pushed onto one support tube and then immediately juxtaposed crushing rings 10, so that a pair of mutually parallel oppositely driven crushing rollers, equipped with evenly distributed arranged field of crushing element nubs 12 has a good Guteinzugsverhalten, that is also able to effectively dissolve in the bulk bed of the hot cement clinker contained Glühnester and produce a crushed material with uniform particle size distribution, whereby the cooling efficiency increases during the cooling of the cement clinker and the subsequent grinding of cement clinker is made uniform.

Die Brechelemente 12 können z. b. längs Mantellinien der Brechringe 10 gleichmäßig beabstandet angeordnet sein, und benachbarte Reihen von Brechelementen können auch auf Lücke so versetzt zueinander angeordnet sein, dass das Feld der gleichmäßig über den Umfang und die Länge der Brechwalzen verteilten Brechelemente entsteht.The crushing elements 12 may, for. b. along the generatrices of the crushing rings 10 may be arranged evenly spaced, and adjacent rows of crushing elements may also be arranged offset to each other gap so that the field of uniformly distributed over the circumference and the length of the crushing rollers crushing elements.

Die Brechelement-Noppen 12 können statt eine zylindrische Konfiguration auch z. B. eine kegelförmige oder auch vieleckige Konfiguration haben. Der Werkstoff der vorspringenden Noppen 12 ist verschleißbeständiger als der Werkstoff des Brechringkörpers. So können die Noppen 12 Hartmetallstifte sein, die durch Verbundguss mit dem Brechringkörper oder durch Aufschweißung auf den Brechringkörper oder durch Einsetzen in entsprechende Ausnehmungen des Brechringkörpers mit diesem fest verbunden sind.The refractive element nubs 12 may instead of a cylindrical configuration also z. B. have a conical or polygonal configuration. The material of the projecting nubs 12 is more resistant to wear than the material of the Brechringkörpers. Thus, the nubs may be 12 hard metal pins, which are firmly connected by composite casting with the crushing ring body or by welding on the crushing ring body or by inserting into corresponding recesses of the crushing ring body with this.

Nach dem Ausführungsbeispiel der Figur 3 können die von der zylindrischen Außenseite der Brechringe 10 vorspringenden Brechelemente auch die Gestalt von parallel zur Brechringdrehachse liegenden Stegen 13 haben, die wiederum sowohl über den Umfang als auch über die Breite aller Brechringe 10 gleichmäßig verteilt angeordnet sind. Auch hier ist infolge der drehfesten Verbindung zwischen den Brechringen 10 und dem zugehörigen Tragrohr vermittels der achsparallelen Durchgangsnut 11 bzw. Nuten sichergestellt, dass nach Aneinanderreihung aller auf ein Tragrohr aufgeschobenen Brechringe 10 das Feld der gleichmäßig verteilt angeordneten von den Brechringen 10 vorspringenden Stegen 13 entsteht.According to the embodiment of FIG. 3 For example, the crushing elements projecting from the cylindrical outer side of the crushing rings 10 can also have the shape of webs 13 lying parallel to the crushing-ring rotational axis, which are in turn distributed uniformly both over the circumference and over the width of all crushing rings 10. Here, too, as a result of the rotationally fixed connection between the breaking rings 10 and the associated support tube by means of the axis-parallel through groove 11 or grooves ensured that after juxtaposition of all pushed onto a support tube crushing rings 10 the Field of uniformly distributed arranged by the crushing rings 10 webs 13 is formed.
