Definitions
- the invention relates to a roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, each roller having a first end and a second end.
- roller crushers When crushing or grinding rock, ore, cement clinker and other hard materials roller crushers may be used having two generally parallel rolls which rotate in opposite directions, towards each other, and which are separated by a gap. The material to be crushed is fed by gravity or choke-fed into the gap.
- One type of roller crusher is called high pressure grinding rollers or high pressure roller crushers.
- This type of roller crusher uses a crushing technique called interparticle crushing.
- interparticle crushing the material to be crushed or pulverised is crushed not only by the crushing surface of the rolls, but also by particles in the material to be crushed, hence the name interparticle crushing.
- the document discloses an improved roll for a roller press capable of withstanding very high nip forces in a press nip for interparticle crushing.
- the roller press has a plurality of spaced wear-resistant surface members embedded in the pressing surface of the roll which are of a material harder than the material of the roll surface surrounding the inserts. By varying the size and number and material properties of the embedded pieces, the wear of the press roll is matched to the materials to be comminuted to minimize wear and to match the wear profile along the roll with extended pressing use.
- a general problem associated with existing high pressure grinding rollers is that the ratio between the roller diameter and the roller width is very important due to a significant edge effect, i.e. the crushing result is reduced at the edges of the rollers. This is because of the fact that material can escape over the edges of the rollers thereby reducing the crushing pressure on the material towards the gap at the edges of the rollers. Thus, these roller parameters cannot be varied to the desired extent.
- roller crusher according to the independent claims.
- a roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap.
- Each roller has a first end and a second end.
- the roller crusher comprises a flange attached to at least one of the ends of one of the rollers.
- the flange extends in a radial direction of the roller, and has a height above an outer surface of the roller which is sufficient to extend across the gap substantially along a nip angle of the roller crusher.

- the roller diameter and the roller width can be varied more freely without a reduced crushing result.
- the flanges will facilitate the providing of an autogenous protection layer on the rollers, consisting of the material to be crushed.
- the height may be sufficient to extend across the gap substantially along a nip angle of the roller crusher, when the gap is set to a maximum operational gap.
- the flange may comprise a feeding structure on the inside of the flange, said structure extending from the inside of the flange towards the other end of the roller. This is advantageous in that the structure will help increasing the pressure on the material towards the gap between the rollers at the edge of the roller even further. The structure will engage with the material which will be moved inside the crushing area and the pressure will be optimized.
- the structure may be arcuate, continuous, intermittent, or a combination thereof. These are preferred embodiments of the structure.
- the flange may be made of a first material and the structure of a second material, said second material being harder than said first material. This way, the structure will act as a wear-resistant element and protect the flange from wear. The structure will also help creating and holding an autogenous protection layer on the flange.

Abstract
Description
- The invention relates to a roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, each roller having a first end and a second end.
- When crushing or grinding rock, ore, cement clinker and other hard materials roller crushers may be used having two generally parallel rolls which rotate in opposite directions, towards each other, and which are separated by a gap. The material to be crushed is fed by gravity or choke-fed into the gap. One type of roller crusher is called high pressure grinding rollers or high pressure roller crushers. This type of roller crusher uses a crushing technique called interparticle crushing. Here, the material to be crushed or pulverised is crushed not only by the crushing surface of the rolls, but also by particles in the material to be crushed, hence the name interparticle crushing.
- One example of a high pressure grinding roller is described in
EP-516 952 - A general problem associated with existing high pressure grinding rollers is that the ratio between the roller diameter and the roller width is very important due to a significant edge effect, i.e. the crushing result is reduced at the edges of the rollers. This is because of the fact that material can escape over the edges of the rollers thereby reducing the crushing pressure on the material towards the gap at the edges of the rollers. Thus, these roller parameters cannot be varied to the desired extent.
- It is an object of the present invention to provide an improvement of the prior art. More particularly, it is an object of the present invention to provide a roller crusher for which the roller diameter and the roller width can be varied more freely without a reduced crushing result.
- These and other objects as well as advantages that will be apparent from the following description of the present invention are achieved by roller crusher according to the independent claims.
- A roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap is provided. Each roller has a first end and a second end. The roller crusher comprises a flange attached to at least one of the ends of one of the rollers. The flange extends in a radial direction of the roller, and has a height above an outer surface of the roller which is sufficient to extend across the gap substantially along a nip angle of the roller crusher. This is advantageous in that the flange eliminates the weakness spot at the edge of the rollers. The flange will help maintaining the material on the outer roller surface. That is to say, due to the flange, the material is prevented from falling over the edge of the roller. This will in turn help increasing the pressure on the material towards the gap between the rollers at the edge of the rollers. By eliminating the weakness spot at the edge of the rollers, the roller diameter and the roller width can be varied more freely without a reduced crushing result. Additionally, the flanges will facilitate the providing of an autogenous protection layer on the rollers, consisting of the material to be crushed.
- The height may be sufficient to extend across the gap substantially along a nip angle of the roller crusher, when the gap is set to a maximum operational gap. The advantages mentioned above will thus be achieved at the most critical moment of the crushing operation.
- The flange may comprise a feeding structure on the inside of the flange, said structure extending from the inside of the flange towards the other end of the roller. This is advantageous in that the structure will help increasing the pressure on the material towards the gap between the rollers at the edge of the roller even further. The structure will engage with the material which will be moved inside the crushing area and the pressure will be optimized.
- The structure may be arcuate, continuous, intermittent, or a combination thereof. These are preferred embodiments of the structure.
- The flange may be made of a first material and the structure of a second material, said second material being harder than said first material. This way, the structure will act as a wear-resistant element and protect the flange from wear. The structure will also help creating and holding an autogenous protection layer on the flange.
- The flange may be divided into a plurality of segments, which is advantageous in that both the manufacturing and mounting of the flange will be facilitated. The flange may be attached to the roller by means of adhesive, bolting, screwing, welding, brazing or any other suitable fastening technique.
- The roller crusher may comprise a flange attached to each end of one of said rollers, respectively. The advantages mentioned above will thus be achieved on both ends of the roller.
- Generally, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to "a/an/the [element, device, component, means, etc]" are to be interpreted openly as referring to at least one instance of said element, device, component, means, etc., unless explicitly stated otherwise. Further, by the term "comprising" it is meant "comprising but not limited to" throughout the application. Lastly, the "nip angle" is defined as the angle between the horizontal plane extending through the centre of a first and a parallel second roller, and a straight line which is drawn from the centre of the first roller to and through a point on the parallel second roller, at which point an active engagement between the second roller and the material to be crushed is started. In the literature concerning this subject, two different nip angles are provided. One nip angle concerns single particle crushing, and one nip angle concerns interparticle crushing. The nip angle concerning interparticle crushing is obviously smaller than the nip angle concerning single crushing. Note that, in the present application, the nip angle concerning interparticle crushing is intended.
- The above, as well as additional objects, features and advantages of the present invention, will be better understood through the following illustrative and non-limiting detailed description of preferred embodiments of the present invention, with reference to the appended drawings, where the same reference numerals will be used for similar elements, wherein:

Theroller crusher 1 comprises aflange 5 attached to the first andsecond end rollers 2 of theroller crusher 1. Theflanges 5 extend in a radial direction of theroller 2 and have a height H above anouter surface 6 of the roller which is sufficient to extend across the gap substantially along a nip angle α of theroller crusher 1. The height H is sufficient to extend across the gap substantially along a nip angle α of theroller crusher 1 when the gap is set to a maximum operational gap. Theflanges 5 are plain and will help maintaining material to be crushed on theouter roller surface 6. That is to say, due to theflanges 5, the material is prevented from falling over the edge of theroller 2. The flanges will also facilitate the providing of an autogenous protection layer on the rollers, consisting of the material to be crushed. Theflanges 5 are divided into a plurality ofsegments 7 in order to facilitate the manufacturing and mounting of the same. Theflanges 5 are, for example, attached to theroller 2 by means of adhesive, bolting or screwing. - In
Fig. 2a , theroller 2 of theroller crusher 1 having aflange 5 on eachend roller 2 is illustrated. Theflanges 5 are plain and will eliminate the weakness spot at the edge of therollers 2. Theflanges 5 will help maintaining the material on theouter surface 6 of therollers 2 and prevent the material from falling over the edge of theroller 2. This will in turn increase the pressure on the material towards the gap between therollers 2 at the edge of therollers 2. -
Fig. 2b illustrates asegment 7 of theflange 5 inFig. 2a . As stated above, theflanges 5 are divided intosegments 7 in order to facilitate the manufacturing and mounting of the same. However, theflanges 5 can naturally be designed as one single unit. - In
Fig. 3a , a second embodiment of theroller 2 of theroller crusher 1 is illustrated. Here, theflanges 5 comprise afeeding structure 8 on the inside of theflanges 5. Thestructure 8 extends from the inside of theflange 5 towards theother end roller 2. Thestructure 8 is continuous and arcuate. Thestructure 8 will increase the pressure on the material towards the gap between therollers 2 at the edge of theroller 2. The material will engage with thestructure 8 and be pressured towards and through the gap, i.e. the material will be choke-fed into the gap. -
Fig. 3b illustrates asegment 7 of theflange 5 inFig. 3a . Naturally, also theflanges 5 according to this second embodiment can be designed as one single unit. - In
Fig. 4a , a third embodiment of theroller 2 of theroller crusher 1 is illustrated. Here, theflanges 5 also comprise afeeding structure 8 on the inside. However, thestructure 8 according to this embodiment is intermittent. -
Fig. 4b illustrates asegment 7 of theflange 5 inFig. 4a . Naturally, also theflanges 5 according to this third embodiment can be designed as one single unit. - In
Fig. 5 , a side view of theroller crusher 1 is illustrated in order to facilitate the understanding of the nip angle α. A first straight line has been drawn from the centre of theright roller 2 to and through a point on theleft roller 2, at which point an active engagement between theleft roller 2 and the material to be crushed is started. The nip angle a is measured between the horizontal plane extending through the centre of the left and right roller, and said first straight line. It is the smaller of the two possible angles which can be obtained in accordance with the definition presented above. In the embodiment illustrated inFig. 5 , the height H of theflange 5 above theouter surface 6 of theroller 2 is sufficient to extend across the gap substantially along the nip angle a of theroller crusher 1. - During the crushing operation of the
roller crusher 1, the material to be crushed is transported to theroller crusher 1 by means of a feeding arrangement and is introduced into a funnel of the feeding arrangement. The material to be crushed is then fed to the gap between the tworollers 2 of theroller crusher 1. Theflange 5 of theroller crusher 1 will help maintaining the material on theouter roller surface 6 of therollers 2 and help increasing the pressure on the material towards the gap between the rollers throughout the width of therollers 2, especially at the edge of therollers 2. When the material has been crushed by means of the two parallel and rotating crushingrollers 2, it travels by gravity out of gap in order to be transported from the unit. - The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended claims.
