Definitions
- the invention relates to an inner lining for cylindrical ball mills.
- Such cylindrical ball mills are called ball tube mills.
- the inner linings of such ball tube mills usually consist of armor plates. If the inner lining is smooth, there is only a point contact between the balls and the inner lining. The grinding effect between the balls and the inner lining is therefore very low and the grinding effect between the balls in the ball cluster is also low because the balls are only slightly circulated due to the smooth inner lining. Since the balls are in direct contact with the inner lining, there is considerable noise.
- the balls in the ball mill cause the balls to brake and the balls are rotated slightly during rotation, so that there is a slight shift in the ball pile, which is not sufficient for a grinding effect in the ball pile.
- a grinding effect therefore mainly arises only between the balls and the grooves of the inner lining.
- Such training is referred to as groove armor.
- the top balls are thrown and are supposed to hit the ball train.
- the impacting balls result in an impact effect, whereby the coarse fraction of the ground material is broken up.
- the balls rest on the inner lining with point contact. There is therefore little or no grinding effect between balls and inner lining.
- the balls are in direct contact with the bare inner lining and there is therefore a lot of noise.
- the object of the invention is to improve the grinding effect.
- the invention consists essentially in the combination of the features known per se that the inner lining has grooves running approximately in the circumferential direction with webs lying between the grooves, and that elevations and / or depressions arranged transversely to the circumferential direction are provided.
- the grooves can run exactly in the circumferential direction or approximately in the circumferential direction along helical lines, such that the base of the grooves and / or the webs have the elevations and / or depressions, and that the base of the grooves and / or the ridges of the webs in the direction of the Grooves are wavy.
- the inventive design combines the advantages of an inner lining with grooves running in the circumferential direction with the advantages of an inner lining equipped with lifting elements, without having to accept the disadvantages of these two designs.
- the balls and the ground material are raised higher in the direction of rotation of the ball mill by the elevations and / or depressions on the groove base and / or on the webs.
- the balls and the material to be ground in the pebble are therefore more strongly layered, so that the less fine grinding in the pebble is improved.
- the top balls are thrown onto the ball train during rotation.
- the ground material is coarsely ground between the balls in the ball pile and the ground material is finely ground in the grooves between the inner lining and the balls.
- the wave-shaped design of the grooved material and / or the ridges of the webs enables the balls to be raised higher, but at the same time offers the advantage that the balls run smoothly in the groove profiles and without any disruptive vibrations and therefore complete fine grinding takes place in the grooves. The end result is improved grinding, protection of the inner lining and noise reduction.
- the arrangement is preferably such that the elevations and / or depressions or the waves on the base of the groove run in the same direction with the elevations and / or depressions on the ridges of the webs and on the same he the inner lining.
- the advantage here is that the depth of the groove remains approximately the same despite the elevations and depressions, so that the balls remain guided in the grooves.
- the grooves have the same transverse profile over the entire circumference of the inner lining. There is thus a uniform grinding of the ground material in the grooves over the entire length of the grooves.
- the intermediate layer between balls and grooves formed by the regrind is not torn.
- the noise-absorbing layer formed by the regrind is maintained and the wave form of the base of the groove and the ridges of the webs ensure that the balls are carried along during rotation.
- the balls striking the ball train naturally produce a certain amount of noise, but this noise development is also considerably reduced by the layer of the ground material located in the grooves.
- the inner lining is usually composed of individual plates, so-called armor plates.
- the plates adjoining one another in the circumferential direction result in a type of arch effect, by means of which these plates are held in their position.
- the plates are divided in the region of the elevations or wave crests.
- the plates naturally have a greater thickness in the area of the wave crests than in the area of the wave valleys. Because the plates are subdivided in the area of the wave crests, the greater thickness of the plates improves the arching effect.
- FIG. 1 shows a section along line II of FIG. 2
- FIG. 2 shows a plan view in the direction of arrow 11 of FIG. 1
- FIG. 3 shows a section along line III - 111 of FIG. 2.
- 4 and 5 show a tube mill with the inner lining, wherein FIG. 4 shows a cross section along line IV-IV of FIG. 5 and FIG. 5 shows a longitudinal section along line V-V of FIG. 4.
- the outside 1 of the armor plates 2 is cylindrical with a radius which corresponds to the inner radius of curvature of the housing of the ball tube mill.
- the armor plate 2 On the inside 3, the armor plate 2 has grooves 4, the base 5 of which is corrugated in the circumferential direction. In the area of the wave crests 6, the plate 2 has a greater thickness than in the area of the wave troughs 7.
- the ridges 8 of the webs 9 existing between the grooves 4 are likewise corrugated and run in the cross section according to FIG. 1 equidistant from the groove base 5.
- the transverse profile 10 the grooves 4 are the same over the entire circumference of the inner lining or over the entire length of the groove 4.
- the web 9 ' is only half the width, since these side edges adjoin the adjacent armor plate 2.
- the end faces 12 which delimit the armor plate 2 in the circumferential direction are inclined and run radially to the axis of the ball tube mill. When these armor plates 2 are joined together, there is a vault effect, which is particularly pronounced in that the end faces 12 are arranged in the region of the wave crests 6.
- this bore 13 is a hole for screwing the armor plates 2 to the wall of the ball tube mill. In view of the great strength of the armor plates 2 in the region of the wave crests 6, this bore 13 can be omitted, the armor plates 2 being fixed in the housing of the ball tube mill solely by the arch effect.
- the inner lining 16 which is composed of the armor plates 2 shown in FIGS. 1 to 3, is located in the drum-shaped housing 14, which is driven to rotate in the direction of the arrow 15. These armor plates 2 cover the entire inner wall of the drum-shaped housing 14.
- the grooves 4 extend over the entire inner circumference and the lifting elements are formed by the wave crests 6 and wave troughs 7, which cause the ball cluster 17 to be carried in the direction of rotation 15.
- the surface on which the pebbles 17 turn when they are rotating is indicated by a dashed line 18.
- the pebble is raised to a height of approximately 19. The balls fall from this height 19 and fall on the ball train indicated by 20.

Abstract
Description
Die Erfindung bezieht sich auf eine Innenauskleidung für zylindrische Kugelmühlen. Solche zylindrische Kugelmühlen werden Kugelrohrmühlen genannt. Die Innenauskleidungen solcher Kugelrohrmühlen bestehen üblicherweise aus Panzerplatten. Wenn die Innenauskleidung glatt ausgebildet ist, besteht zwischen den Kugeln und der Innenauskleidung nur eine Punktberührung. Die Mahlwirkung zwischen den Kugeln und der Innenauskleidung ist daher sehr gering und die Mahlwirkung zwischen den Kugeln im Kugelhaufen ist gleichfalls gering, weil infolge der glatten Innenauskleidung die Kugeln nur geringfügig umgewälzt werden. Da die Kugeln unmittelbar mit der Innenauskleidung in Berührung stehen, ergibt sich eine beträchtliche Lärmentwicklung. Es ist bekannt, die Innenauskleidung mit ungefähr in Umfangsrichtung verlaufenden Rillen auszubilden, deren Querschnittsproifl einen Krümmungsradius aufweist, der bei den bekannten Kugelmühlen ungefähr dem Krümmungsradius der grössten Kugel entspricht, wobei zwischen diesen Rillen Stege bestehen (AT-B-283 092). In diesen Rillen wird ein Ausweichen des Mahlgutes quer zu den Rillen weitgehend verhindert. Das Mahlgut bleibt somit als Zwischenlage zwischen der Innenauskleidung und den Kugeln in den Rillen. Es ergibt sich eine Linienberührung zwischen Kugeln und Rillen bzw. Mahlgut. Es wird dadurch die Mahlung zwischen Kugeln und Innenauskleidung wesentlich verbessert und infolge des zwischen der Innenauskleidung und den Kugeln befindlichen Mahlgutes ergibt sich eine beträchtliche Lärmverminderung. Durch das in der Kugelmühle befindliche Mahlgut erfolgt eine Bremsung der Kugeln und bei der Rotation werden daher die Kugeln, geringfügig mitgenommen, so dass eine geringfügige Umschichtung im Kugelhaufen erfolgt, welche aber nicht für einen Mahleffekt im Kugelhaufen ausreicht. Ein Mahleffekt ergibt sich daher in der Hauptsache nur zwischen den Kugeln und den Rillen der Innenauskleidung. Solche Ausbildungen werden als Rillenpanzerung bezeichnet. Es ist weiters bekannt, die Innenauskleidung glatt und ohne Rillen aber mit quer zur Umfangsrichtung angeordneten Erhebungen und Vertiefungen auszubilden, welche als Hubelemente bezeichnet werden, weil sie die Kugeln anheben. Durch diese Hubelemente werden die Kugeln in Drehrichtung der Kugelmühle wirksam mitgenommen. Es erfolgt daher eine starke Umschichtung der Kugeln und eine gute Mahlung im Kugelhaufen. Die obersten Kugeln werden abgeworfen und sollen auf die Kugelschleppe auftreffen. Die auftreffenden Kugeln ergeben eine Schlagwirkung, wodurch der grobe Anteil des Mahlgutes zertrümmert wird. Die Kugeln liegen aber bei dieser Ausführungsform der Innenauskleidung mit Punktberührung an der Innenauskleidung auf. Es ergibt sich daher nur eine geringe oder keine Mahlwirkung zwischen Kugeln und Innenauskleidung. Die Kugeln sind in unmittelbarer Berührung mit der nackten Innenauskleidung und es entsteht daher eine starke Lärmentwicklung. In beiden Fällen, sowohl bei der Ausbildung der Innenauskleidung mit Rillen als auch bei der Ausbildung der Innenauskleidung mit Hubelementen ist die Mahlwirkung unbefriedigend.The invention relates to an inner lining for cylindrical ball mills. Such cylindrical ball mills are called ball tube mills. The inner linings of such ball tube mills usually consist of armor plates. If the inner lining is smooth, there is only a point contact between the balls and the inner lining. The grinding effect between the balls and the inner lining is therefore very low and the grinding effect between the balls in the ball cluster is also low because the balls are only slightly circulated due to the smooth inner lining. Since the balls are in direct contact with the inner lining, there is considerable noise. It is known to form the inner lining with grooves running approximately in the circumferential direction, the cross-sectional profile of which has a radius of curvature which, in the known ball mills, corresponds approximately to the radius of curvature of the largest ball, webs being present between these grooves (AT-B-283 092). In these grooves, the regrind is prevented from escaping transversely to the grooves. The regrind thus remains as an intermediate layer between the inner lining and the balls in the grooves. There is a line contact between balls and grooves or regrind. As a result, the grinding between balls and inner lining is significantly improved and as a result of the ground material located between the inner lining and the balls there is a considerable reduction in noise. The balls in the ball mill cause the balls to brake and the balls are rotated slightly during rotation, so that there is a slight shift in the ball pile, which is not sufficient for a grinding effect in the ball pile. A grinding effect therefore mainly arises only between the balls and the grooves of the inner lining. Such training is referred to as groove armor. It is also known to form the inner lining smooth and without grooves but with elevations and depressions arranged transversely to the circumferential direction, which are referred to as lifting elements because they lift the balls. These lifting elements effectively take the balls with them in the direction of rotation of the ball mill. There is therefore a strong layering of the balls and good grinding in the ball pile. The top balls are thrown and are supposed to hit the ball train. The impacting balls result in an impact effect, whereby the coarse fraction of the ground material is broken up. In this embodiment of the inner lining, however, the balls rest on the inner lining with point contact. There is therefore little or no grinding effect between balls and inner lining. The balls are in direct contact with the bare inner lining and there is therefore a lot of noise. In both cases, both in the formation of the inner lining with grooves and in the formation of the inner lining with lifting elements, the grinding effect is unsatisfactory.
Aufgabe der Erfindung ist es, die Mahlwirkung zu verbessern. Zur Erfüllung dieser Aufgabe besteht die Erfindung im wesentlichen in der Kombination der für sich bekannten Merkmale, dass die Innenauskleidung ungefähr in Umfangsrichtung verlaufende Rillen mit zwischen den Rillen liegenden Stegen aufweist, und dass quer zur Umfangsrichtung angeordnete Erhebungen und/ oder Vertiefungen vorgesehen sind. Die Rillen können hiebei genau in Umfangsrichtung oder auch ungefähr in Umfangsrichtung nach Schraubenlinien verlaufen, dass der Grund der Rillen und/oder die Stege die Erhebungen und/oder Vertiefungen aufweisen, und dass der Grund der Rillen und/oder die Kämme der Stege in Richtung der Rillen wellenförmig verlaufen. Durch die erfindungsgemässe Ausbildung werden die Vorteile einer Innenauskleidung mit in Umfangsrichtung verlaufenden Rillen mit den Vorteilen einer mit Hubelementen ausgestatteten Innenauskleidung vereinigt, ohne die Nachteile dieser beiden Ausbildungen in Kauf nehmen zu müssen. Zwischen den in der äussersten Schicht befindlichen Kugeln und den Rillen befindet sich eine Schicht des Mahlgutes. Es wird dadurch eine Feinmahlung des Mahlgutes erreicht und es wird die Lärmentwicklung beträchtlich vermindert. Durch die Erhebungen und/oder Vertiefungen am Rillengrund und/oder auf den Stegen werden die Kugeln mit dem Mahlgut in Drehrichtung der Kugelmühle höher angehoben. Es erfolgt daher eine stärkere Umschichtung der Kugeln und des Mahlgutes im Kugelhaufen, so dass die weniger feine Mahlung im Kugelhaufen verbessert wird. Die jeweils obersten Kugeln werden bei der Drehung auf die Kugelschleppe abgeworfen. Durch die sich ergebende Schlagwirkung wird der infolge seines geringeren spezifischen Gewichtes auf dem Kugelhaufen liegende grobe Anteil des Mahlgutes zertrümmert, und es wird überdies die Bewegung der Kugeln im Kugelhaufen durch diese Schlagwirkung vergrössert. Im Kugelhaufen wird das Mahlgut zwischen den Kugeln gröber gemahlen und zwischen der Innenauskleidung und den Kugeln wird in den Rillen das Mahlgutfein gemahlen. Die wellenförmige Ausbildung des Rillengutes und/ oder der Kämme der Stege ermöglicht das höhere Anheben der Kugeln, bietet aber gleichzeitig den Vorteil, dass die Kugeln in den Rillenprofilen ruhig und ohne störende Erschütterungen ablaufen und daher eine vollständige Feinmahlung in den Rillen erfolgt. Im Endergebnis ergibt sich eine verbesserte Mahlung, eine Schonung der Innenauskleidung und eine Lärmverminderung.The object of the invention is to improve the grinding effect. To achieve this object, the invention consists essentially in the combination of the features known per se that the inner lining has grooves running approximately in the circumferential direction with webs lying between the grooves, and that elevations and / or depressions arranged transversely to the circumferential direction are provided. The grooves can run exactly in the circumferential direction or approximately in the circumferential direction along helical lines, such that the base of the grooves and / or the webs have the elevations and / or depressions, and that the base of the grooves and / or the ridges of the webs in the direction of the Grooves are wavy. The inventive design combines the advantages of an inner lining with grooves running in the circumferential direction with the advantages of an inner lining equipped with lifting elements, without having to accept the disadvantages of these two designs. Between the balls in the outermost layer and the grooves there is a layer of the ground material. Fine grinding of the ground material is thereby achieved and noise generation is considerably reduced. The balls and the ground material are raised higher in the direction of rotation of the ball mill by the elevations and / or depressions on the groove base and / or on the webs. The balls and the material to be ground in the pebble are therefore more strongly layered, so that the less fine grinding in the pebble is improved. The top balls are thrown onto the ball train during rotation. As a result of the resulting impact, the coarse fraction of the ground material lying on the pebble due to its lower specific weight is destroyed, and the movement of the balls in the pebble is also increased by this impact. The ground material is coarsely ground between the balls in the ball pile and the ground material is finely ground in the grooves between the inner lining and the balls. The wave-shaped design of the grooved material and / or the ridges of the webs enables the balls to be raised higher, but at the same time offers the advantage that the balls run smoothly in the groove profiles and without any disruptive vibrations and therefore complete fine grinding takes place in the grooves. The end result is improved grinding, protection of the inner lining and noise reduction.
Vorzugsweise ist die Anordnung so getroffen, dass die Erhebungen und/oder Vertiefungen bzw. die Wellen am Rillengrund mit den Erhebungen und/oder Vertiefungen auf den Kämmen der Stege gleichsinnig verlaufen und auf gleichen Erzeugenden der Innenauskleidung liegen. Hiebei wird der Vorteil erreicht, dass die Tiefe der Rille trotz der Erhebungen und Vertiefungen ungefähr gleich bleibt, so dass die Kugeln in den Rillen geführt bleiben. Gemäss einer bevorzugten Ausführungsform der Erfindung weisen die Rillen über den gesamten Umfang der Innenauskleidung gleiches Querprofil auf. Es erfolgt somit über die ganze Länge der Rillen eine gleichmässige Mahlung des in den Rillen befindlichen Mahlgutes. Die vom Mahlgut gebildete Zwischenschicht zwischen Kugeln und Rillen wird nicht zerrissen. Die durch das Mahlgut gebildete lärmdämmende Schicht wird aufrecht erhalten und durch die Wellenform des Rillengrundes und der Kämme der Stege wird die Mitnahme der Kugeln bei der Rotation gewährleistet. Die auf die Kugelschleppe auffallenden Kugeln ergeben naturgemäss eine gewisse Lärmentwicklung, jedoch wird auch diese Lärmentwicklung durch die in den Rillen befindliche Schicht des Mahlgutes beträchtlich vermindert.The arrangement is preferably such that the elevations and / or depressions or the waves on the base of the groove run in the same direction with the elevations and / or depressions on the ridges of the webs and on the same he the inner lining. The advantage here is that the depth of the groove remains approximately the same despite the elevations and depressions, so that the balls remain guided in the grooves. According to a preferred embodiment of the invention, the grooves have the same transverse profile over the entire circumference of the inner lining. There is thus a uniform grinding of the ground material in the grooves over the entire length of the grooves. The intermediate layer between balls and grooves formed by the regrind is not torn. The noise-absorbing layer formed by the regrind is maintained and the wave form of the base of the groove and the ridges of the webs ensure that the balls are carried along during rotation. The balls striking the ball train naturally produce a certain amount of noise, but this noise development is also considerably reduced by the layer of the ground material located in the grooves.
Üblicherweise ist die Innenauskleidung aus einzelnen Platten, sogenannten Panzerplatten, zusammengesetzt. Die in Umfangsrichtung aneinander anschliessenden Platten ergeben eine Art von Gewölbewirkung, durch welche diese Platten in ihrer Lage gehalten werden. Bei einer solchen Ausbildung der Innenauskleidung sind gemäss einer bevorzugten Ausführungsform der Erfindung die Platten im Bereich der Erhebungen bzw. Wellenberge unterteilt. Die Platten weisen naturgemäss im Bereich der Wellenberge eine grössere Stärke auf als im Bereich der Wellentäler. Dadurch, dass die Unterteilung der Platten im Bereich der Wellenberge erfolgt, ist durch die grössere Stärke der Platten die Gewölbewirkung verbessert. Dies hat insbesondere bei einer schraubenlosen Ausbildung der Innenauskleidung Vorteile, da bei einer solchen schraubenlosen Ausbildung die Befestigung der Platten an der Wandung der Rohrmühle durch die Gewölbewirkung allein erfolgt.The inner lining is usually composed of individual plates, so-called armor plates. The plates adjoining one another in the circumferential direction result in a type of arch effect, by means of which these plates are held in their position. With such a design of the inner lining, according to a preferred embodiment of the invention, the plates are divided in the region of the elevations or wave crests. The plates naturally have a greater thickness in the area of the wave crests than in the area of the wave valleys. Because the plates are subdivided in the area of the wave crests, the greater thickness of the plates improves the arching effect. This has advantages in particular in the case of a screwless design of the inner lining, since in the case of such a screwless design the plates are fastened to the wall of the tube mill solely by the arch effect.
