Abstract
Description
Die Erfindung ist auf ein Messvorrichtung zur Messung des Verschleißes der Mahlwalzen von Zweiwalzenmaschinen, insbesondere von Hochdruck-Walzenpressen zur Druckzerkleinerung körnigen Gutes gerichtet.The invention is directed to a measuring device for measuring the wear of the grinding rollers of two-roller machines, in particular of high-pressure roller presses for pressure comminution of granular material.
Bei Walzenbrechern und Walzenmühlen wird körniges, sprödes Mahlgut in den Walzenspalt, durch den die beiden drehbar gelagerten, gegenläufig rotierbaren Mahlwalzen voneinander getrennt sind, eingezogen und dort einer Druckzerkleinerung unterworfen.In the case of roller crushers and roller mills, granular, brittle regrind is drawn into the roller gap, through which the two rotatably mounted, counter-rotating grinding rollers are separated from one another and subjected to pressure reduction there.
Bekannt ist auch die sogenannte Gutbettzerkleinerung im Walzenspalt einer Hochdruck-Walzenpresse, bei der die einzelnen Partikel des eingezogenen Mahlgutes in einem Gutbett, d. h. in einer zwischen den beiden Walzenoberflächen zusammengedrückten Materialschüttung bei Anwendung eines extrem hohen Druckes gegenseitig zerkleinert werden (EP-A-0 084 383). Dabei sind die Walzenoberflächen einer außerordentlich hohen Beanspruchung ausgesetzt, woraus u. a. ein hoher Verschleiß resultiert. Es ist bekannt, durch unterschiedliche Gestaltung und Beschichtung der dem Verschleiß ausgesetzten Walzenoberflachen diesem Verschleiß entgegen zu wirken. So werden in der EP-A-0 361 172 auf den Walzengrundkörper durch Schweißen verschiedene Schichten aus unterschiedlichen Legierungen zum Verschleißschutz aufgetragen.Also known is the so-called material bed comminution in the nip of a high-pressure roller press, in which the individual particles of the ground material in a material bed, ie. H. are mutually comminuted in a material bed compressed between the two roller surfaces using an extremely high pressure (EP-A-0 084 383). The roller surfaces are exposed to extremely high loads, which a. high wear results. It is known to counteract this wear by different design and coating of the roller surfaces exposed to wear. In EP-A-0 361 172, for example, various layers of different alloys are applied to the roller base body by welding to protect against wear.
Die Kenntnis des Oberflächenzustandes der Mahlwalzen ist für den Betrieb von Zweiwalzenmaschinen, insbesondere beim Betrieb von HochdruckWalzenpressen wichtig, da rechtzeitig erkannt worden muß, wann die zum Verschleißschutz aufgetragenen Schichten erneuert werden müssen, damit keine bleibenden Schäden am Walzengrundkörper entstehen können. Weiterhin können durch Inhomogenitäten des Mahlgutes (enthaltene Fremdkörper, beispielsweise Mahlkugeln) oder durch Materialfehler der Mahlwalze Oberflächenablösungen an der Mahlwalze herbeigeführt werden, die schnell erkannt werden müssen, um größere Schäden an der Mahlwalze zu verhindern.Knowledge of the surface condition of the grinding rollers is essential for the operation of two-roller machines, particularly when operating high-pressure roller presses This is important because it must be recognized in good time when the layers applied to protect against wear must be renewed so that no permanent damage to the roller body can occur. Furthermore, surface inhomogeneities on the grinding roller can be brought about by inhomogeneities of the grinding material (foreign bodies contained, for example grinding balls) or by material defects in the grinding roller, which detachments must be quickly recognized in order to prevent major damage to the grinding roller.
Hinsichtlich des Betriebsverhaltens der Zweiwalzenmaschine ist die Beschaffenheit der Oberfläche der Mahlwalzen von Bedeutung, da beispielsweise das Einzugsverhalten des Mahlgutes weitgehend von der Oberflächenbeschaffenheit der Mahlwalzen, und vom Einzugsverhalten der Durchsatz an Mahlgut und der Zerkleinerungsfortschritt abhängen, so daß auch aus diesen Gründen die Oberflächenbeschaffenheit der Mahlwalzen zu überwachen ist.With regard to the operating behavior of the two-roll machine, the nature of the surface of the grinding rollers is important, since, for example, the drawing-in behavior of the ground material largely depends on the surface quality of the grinding rollers, and on the drawing-in behavior the throughput of ground material and the size reduction progress, so that the surface properties of the grinding rollers are also for these reasons is to be monitored.
Die üblicherweise durchgeführte visuelle Beurteilung des Oberflächenzustandes wird erschwert durch die schnelle Drehzahl dar Mahlwalzen, so daß eine Beurteilung meist nur im Stillstand der Mahlwalzen erfolgen kann. Oft ist auch die Mahlwalze mit anhaftendem Mahlgut bedeckt, insbesondere wenn durch Oberflächenablösungen in der Oberfläche Hohlräume entstandenen sind, wodurch gleichfalls eine sichere Beurteilung erschwert wird.The usual visual assessment of the surface condition is made more difficult by the fast speed of the grinding rollers, so that an assessment can usually only be made when the grinding rollers are at a standstill. The grinding roller is often also covered with adhering regrind, in particular if voids have formed in the surface due to surface detachments, which also makes a reliable assessment more difficult.
Aus Patent Abstracts of Japan vol. 010, no. 003, 8. Jan. 1986 JP-60 161 511 ist eine Meßanordnung bekannt, die seitlich neben einer Walze einer Zweiwalzenmaschine (senkrecht zur Materialflußrichtung) angeordnet ist, um die Spaltweite zwischen den beiden Walzen während des Betriebs der Zweiwalzenmaschine berührungslos unter Berücksichtigung des Verschleisses der Walzen zu messen. Eigenbewegungen der Mahlwalze, die sich auf eine Änderung des Walzenspaltes auswirken, werden dabei gleichzeitig mit erfaßt. Außerdem wird durch anhaftendes Mahlgut, das den Walzenspalt verringert, das sich bei der bekannten Meßanordnung ergebende Verschleißbild ebenfalls nachteilig beeinflußt.From Patent Abstracts of Japan vol. 010, no. 003, Jan. 8, 1986 JP-60 161 511 a measuring arrangement is known, which is arranged laterally next to a roller of a two-roll machine (perpendicular to the material flow direction) to the gap width between the two rolls during the operation of the two-roll machine without contact Taking into account the wear of the rollers. Own movements of the grinding roller, which affect a change in the roller gap, are recorded at the same time. In addition, adhering regrind, which reduces the nip, also adversely affects the wear pattern resulting from the known measuring arrangement.
Aufgabe der Erfindung ist es, eine Messvorrichtung zu schaffen, das die mechanische Verschleißtiefe an der Walzenoberfläche erfaßt, diese zuverlässig anzeigt und das in der Lage ist, die Messung während des Betriebs der Zweiwalzenmaschine durchzuführen und bei dem an den Mahlwalzen anhaftendes Mahlgut den erhaltenen Meßwert nicht verfälscht.The object of the invention is to provide a measuring device which detects the mechanical depth of wear on the roller surface, reliably indicates this and which is able to carry out the measurement during the operation of the two-roller machine and does not produce the measured value obtained in the regrind adhering to the grinding rollers adulterated.
Die gestellte Aufgabe wird gemäß der Erfindung mit den Maßnahmen des Kennzeichnungsteils des Anspruchs 1 gelöst.The object is achieved according to the invention with the measures of the characterizing part of
Durch die berührungslose Messung mittels eines Meßwertaufnehmers kann in kurzen Zeitintervallen praktisch jeder Bereich der Mahlwalzenoberfläche erfaßt werden und, da das Meßsignal nur auf das Metall der Mahlwalze anspricht, gibt das Meßsignal - entsprechend umgeformt - ein exaktes Bild der Oberflächenbeschaffenheit der Mahlwalze wieder. Auf diese Weise ist zu jedem Zeitpunkt der aktuelle Verschleißzustand der Mahlwalzen abrufbar oder wird durch entsprechende Vorrichtungen ständig angezeigt. Die Messung erfolgt gemäß der Erfindung zweckmäßig von oben an der Scheitellinie der Mahlwalzen, da auf diese Weise auftretende Eigenbewegungen der Mahlwalze, beispielsweise durch Schiefstellung, keine den Meßwert verfälschenden Einflüsse ausüben können.Due to the contactless measurement by means of a sensor, practically every area of the grinding roller surface can be detected in short time intervals and, since the measuring signal only responds to the metal of the grinding roller, the measuring signal - appropriately transformed - gives an exact picture of the surface condition of the grinding roller. In this way, the current state of wear of the grinding rollers can be called up at any time or is constantly displayed by appropriate devices. According to the invention, the measurement is expediently carried out from above at the apex line of the grinding rollers, since self-movements of the grinding roller which occur in this way, for example due to misalignment, cannot exert influences which distort the measured value.
In vorteilhafter Ausgestaltung der Erfindung wird das Meßsignal durch einen auf die berührungslose Annäherung von Metall ansprechenden induktiven Wegaufnehmer gebildet, der oberhalb der Mahlwalze über die gesamte Walzenlänge verschiebbar angeordnet ist. Es ist aber auch möglich, mehrere Meßwertaufnehmer mit Abstand nebeneinander über die gesamte Mahlwalzenlänge oberhalb der Mahlwalze anzuordnen, wodurch wie bei der verschiebbaren Anordnung des Meßwertaufnehmers gleichfalls die gesamte Mahlwalzenoberfläche erfaßt werden kann. Nachfolgend wird an einem Ausführungsbeispiel der Gegenstand der Erfindung anhand von schematischen Zeichnungsfiguren näher erläutert.In an advantageous embodiment of the invention, the measurement signal is formed by an inductive displacement sensor which is responsive to the contactless approach of metal and which is arranged displaceably over the entire roller length above the grinding roller. However, it is also possible to arrange a plurality of transducers next to one another at a distance over the entire length of the grinding roller above the grinding roller, so that the entire grinding roller surface can also be detected, as with the displaceable arrangement of the transducer. The subject matter of the invention is explained in more detail below using an exemplary embodiment with the aid of schematic drawing figures.
Es zeigt:
- Fig. 1:
- Einen Schnitt in axialer Richtung durch eine Mahlwalze mit verschiebbarem Meßwertaufnehmer;
- Fig. 2:
- einen Schnitt in radialer Richtung durch eine Mahlwalze gemäß Fig. 1.
- Fig. 1:
- A section in the axial direction through a grinding roller with a displaceable sensor;
- Fig. 2:
- 2 shows a section in the radial direction through a grinding roller according to FIG. 1.
In Fig. 1 ist einem Schnitt parallel zur Walzenachse eine Mahlwalze (1) in einem Pressenrahmen (2) drehbar gelagert dargestellt. Oberhalb der Mahlwalze (1) befindet sich der Meßwertaufnehmer (3), der mit dem Pressenrahmen (2) in Pfeilrichtung verschiebbar verbunden ist. Bei entsprechendem Meßbereich des Meßwertaufnehmers (3) können somit, wie insbesondere die Fig. 2 zeigt, sowohl Erhebungen (4), die auf der Mahlwalzenoberfläche zur Verbesserung des Einzugsverhaltens des Mahlgutes aufgebracht sind, als auch lokale Vertiefungen (5), die durch Oberflächenablösungen verursacht sind, erfaßt werden. Da das Meßsignal nur durch den Abstand zwischen dem Meßwertaufnehmer und dem Metall der Mahlwalze gebildet wird, werden an der Mahlwalze anhaftendes oder die Vertiefungen (5) ausfüllendes Mahlgut, soweit es nicht magnetisierbar ist, bei der Bildung des Meßsignals nicht berücksichtigt. Das Meßsignal kommt also auch dann zustande, wenn die Mahlwalzenoberfläche einer visuellen Beurteilung nicht zugängig ist.In Fig. 1 a section parallel to the roller axis of a grinding roller (1) is shown rotatably mounted in a press frame (2). Above the grinding roller (1) is the sensor (3), which is connected to the press frame (2) so that it can move in the direction of the arrow. With a corresponding measuring range of the transducer (3), as can be seen in particular in FIG. 2, both elevations (4), which are applied to the grinding roller surface to improve the feeding behavior of the material to be ground, and local depressions (5), which are caused by surface detachments are detected. Since the measurement signal is formed only by the distance between the transducer and the metal of the grinding roller, regrind that adheres to the grinding roller or fills the depressions (5), insofar as it cannot be magnetized, is not taken into account in the formation of the measuring signal. The measurement signal also occurs when the grinding roller surface is not accessible to a visual assessment.
Über in der Zeichnung nicht dargestellte Leitungen kann das mit dem Meßwertaufnehmer erhaltene Meßsignal zu einem beliebigen Ort, beispielsweise dem Leitstand der Zweiwalzenmaschine, geführt und dort nach entsprechender Umformung registriert und/oder optisch, beispielsweise mittels Leuchtdioden, angezeigt und/oder als akustisches Signal wiedergegeben werden.Via lines not shown in the drawing, the measurement signal obtained with the transducer can be routed to any location, for example the control center of the two-roll machine, and can be registered there and / or optically displayed, for example by means of light-emitting diodes, and / or displayed as an acoustic signal .
