Definitions
- the invention relates to a roller press for grinding of particulate material such as cement raw materials, cement clinker and similar materials.
- the invention relates to a roller press which has two oppositely rotating rollers with a first roller being movably supported relative to the second roller so that the rollers form between them a roller gap, and a co-rotating annular disc, attached to an end of one of the rollers and extending over in the area around the roller gap and the end of the other roller, and which annular disc is movable towards the end surface of the other roller in the direction of the roller axis and under the action of a number of springs.
- a roller press of the aforementioned kind is known from DE 40 37 816 A1 , and may for example be used for grinding particulate material.
- an annular disc to restrict and cover the roller gap at the ends of the rollers in order to limit the flow of material which is laterally discharged at the ends of the rollers during the operation of the roller press.
- the annular disc is spring-loaded so as to allow minor axial movements in instances where, for example, material particles which are hard and difficult-to-ghnd penetrate the area between the annular disc and the rollers, or in instances where one of the rollers is in an inclined position relative to the other roller.
- roller press of the kind mentioned in the introduction which is characterized in that the annular disc is divided into a number of sectors over its circumference, each individually biased by one or more springs towards the end surface (3a) of the other roller (3).
- the ring sectors have end stops for the axial movement of the ring sectors in the direction towards the roller.
- the end stops may be made up of any suitable means effectively restricting the axial movement of the ring sector in the direction towards the roller.
- an end stop may comprise a number of studs having a certain axial extension and being attached either to the end of the roller or to the ring sector.
- the axial extension of the end stop is adjustable.
- the end stop can also be used to pre-tension the springs.
- the end stop is made up of a number of adjustable screws which are fitted in through-going threaded holes in the ring sector.
- the ring sectors are fitted on the non-movable roller since in a situation where the movable roller is distorted there would otherwise be a risk of collision between the ring sectors and the roller.
- Any distortion during operation of the movable roller would mainly be ascribable to axial segregation of the material in the feed shaft.
- Such segregation entails that fine material may be present at one end of the roller gap while coarse material is present at the other end of the roller gap. This will lead to an uneven grinding bed thickness along the roller gap, resulting in a distortion of the movable roller. Where the grinding bed thickness is small, the end of the movable roller will move across the stationary roller.
- the axial pressure from the grinding bed will actuate the springs in the ring sector using a force which is so strong that the springs will be compressed to such an extent that the sectors of the annular disc are moved away to avert a potential collision with the end of the movable roller now beyond the end of the stationary roller.
- Fig. 1 shows a section of a roller press
- Fig. 2 shows a sectional view of the roller press illustrated in Fig. 1.
- Fig. 1 shows a roller press 1 which comprises two oppositely rotating rollers 2, 3, where one roller is movably supported relative to the second roller, with the rollers 2, 3 forming between them a roller gap 4.
- a roller press 1 which comprises two oppositely rotating rollers 2, 3, where one roller is movably supported relative to the second roller, with the rollers 2, 3 forming between them a roller gap 4.
- On both ends of one of the rollers 2 multiple co-rotating ring sectors 5 are symmetrically fitted around the axis of the roller 2.
- Fig. 2 shows the two oppositely rotating rollers 2, 3 and a single co-rotating ring sector 5 which, subject to actuation by a number of springs 7, is mounted for movement in the direction of the roller axis, and extends over the end surface 3a of the second roller 3 in the area around the roller gap 4.
- the ring sector 5 Via a frame or mounting structure 6, the ring sector 5 is attached to the roller end 2a, for example by means of screws 9, and the springs 7 lie true against the frame structure 6 and the ring sector 5.
- the frame structure 6 is equipped with arms 6a to control the movements of the ring sector 5.
- End stops 8, in the form of, for example, one or more bolts, are fitted in threaded holes in the ring sector 5 on both sides of the latter and engage the end surface 2a of the roller 2. Adjustment of the end stops 8 will cause the ring sector 5 to move axially, thereby attaining the desired position of the ring sector 5.
