Definitions
- the invention relates to a press roll for a roll press, in particular for the comminution of highly abrasive substances, with a roll body which (for the wear protection in the edge regions) on one or both roll edges a plurality of circumferentially spaced and spaced apart in the tangential direction or circumferential direction pocket-like recesses, which are each formed laterally and open at the top, wherein in the individual pocket-like recesses only one hard body is used as an exchangeable edge protection element.
- a roll press usually has two press rolls.
- the roll press is used in particular to comminution and in particular high-pressure crushing of coarse mineral feed materials such. As ores, cement clinker, slag, kimberlite, coal or ceramic base materials.
- Such a roller press is also referred to as a good bed roller mill.
- the invention also encompasses roll presses for the compaction or briquetting of material.
- EP 1 502 650 B1 describes a press roll with circumferential recesses in the form of annular shoulders arranged on the roll edges, a multiplicity of wear protection elements being arranged one behind the other in the circumferential direction in each of these recesses.
- the wear protection elements made of hard metal form a quasi-closed ring, which should offer a high wear protection.
- the wear protection elements can be attached by gluing, stapling or soldering directly in the circumferential ring shoulders.
- the wear protection elements are mounted in the circumferential recesses close together, so that
- the wear layer of the press roll has substantially planar zones of a highly wear-resistant material, the z. B. tiles or tiles can be formed. The spaces between the highly wear-resistant zones are filled with a material of other wear resistance.
- the tiles or tiles can z. B. made of a metal matrix composite material by hot isostatic pressing. These prefabricated hard bodies are then fastened permanently to the basic body together with the interspace material by hot isostatic pressing.
- the invention is the technical problem of providing a press roll for a roller press, which is characterized by a particularly resistant, yet interchangeable wear protection on the roll edges.
- the invention teaches in a generic press roll of the type described above with individual pocket-like
- the length of the pocket-like recesses and the length of the edge protection elements used in the tangential direction or circumferential direction is greater than the distance between two immediately adjacent recesses.
- the invention is initially based on the recognition that it is fundamentally advantageous to equip the press roll on the roll edges with exchangeable and consequently detachable edge protection elements.
- Detachable means within the scope of the invention that these edge protection elements can be removed from the recesses without destruction for the purpose of replacement.
- the detachable edge protection elements are not arranged in circumferential grooves or annular shoulders, but rather in individual pocket-like recesses, wherein in each individual pocket-like recess only one hard body is detachably inserted as an exchangeable edge protection element.
- the solution according to the invention has the advantage that the individual edge protection elements, despite the very high pressing forces, do not touch each other and consequently can not butt against one another or be pressed against one another. Damage to the individual edge protection elements is thus avoided, and in particular damage due to breakage, which in principle is to be feared with brittle hard materials.
- the arrangement of the edge protection elements in individual, locally limited pockets moreover has the advantage that the edge protection elements are not only supported on a step-like shoulder on the underside and on the inside, but also laterally. Because the design of the roll edge with individual, locally limited pockets has the consequence that the individual recesses are delimited from each other by "dividers", so that
- the edge protection elements are supported tangentially by these dividers.
- the high pressure forces that occur can be well diverted into the body.
- the solution according to the invention over the known arrangements with circumferential annular shoulders has the advantage that can form an autogenous wear protection in the region of the partitions and thus in the area between the individual pockets and edge protection elements, which protects the edges of the wear protection elements used to a particular extent.
- the autogenous wear protection can build up not only in the remaining roller areas, but also in the edge area and between the individual edge protection elements. This has the consequence that a auskolkender wear in these zones is avoided.
- the pocket-like recesses are - as described - each side and top open.
- Laterally open means in the context of the invention based on the roller frontally open, that is open on the side facing away from the roll center in the axial direction.
- Open at the top means within the scope of the invention open on the side facing away from the roll axis in the radial direction. In detail, it will be discussed in the figure description.
- the press roll according to the invention is characterized by a reliable edge protection over the entire peripheral region of the press roll
- the length of the recesses and the length of the edge protection elements used in the circumferential direction is (significantly) greater than the (tangential) distance between two immediately adjacent recesses and consequently significantly greater than the thickness of the arranged between the recesses separating webs.
- the length of the recesses and the length of the edge protection elements is more than two times, preferably more than five times, more preferably more than ten times the distance between the individual pockets.
- the relatively small distance between the recesses compared to the length of the recesses also has the advantage that an autogenous wear protection can also be formed properly in the edge region.
- the dividers between the recesses provide sufficient stability to achieve the advantages already described.
- the invention proposes, in a preferred embodiment, that the (tangential) distance between two immediately adjacent recesses is more than 3 mm, preferably more than 4 mm.
- edge protection elements arranged in the individual pockets can have geometrically very different shapes.
- Edge protection elements are preferably used, which are square, for example rectangular, in the plan view of the roll surface. It is within the scope of the invention that the edge protection elements in a side view of the roller angular, z. B. are rectangular, so that the edge protection elements z. B. may have the shape of a cuboid. Alternatively, however, edge protection elements of other geometry are also covered by the invention, which may also have a non-cornered shape, particularly in plan view.
- the invention preferably proposes that the side recesses in the side view at least partially curved wall surfaces and the edge protection elements at least partially have adapted to the curved wall surface, curved outer contour.
- the already described lateral support of the edge protection elements and thus the derivation of the compressive forces into the main body can thereby be optimized.
- such pockets with curved wall or floor areas can be particularly easy to introduce into the body, z. B. by milling.
- edge protection elements made of various materials.
- the edge protection elements used detachably in the pocket-like recesses made of hard metal or hard metal similar materials eg. As cermets exist.
- edge protection elements of metal matrix composite material may preferably be used within the scope of the invention.
- MMC metal matrix composite material
- These edge protection elements made of MMC have the advantage over tungsten carbides that they can be designed less brittle by suitable choice of matrix materials, the proportion of which is much higher in comparison to carbide in MMC, and thus are less sensitive to bending.
- the selected composition of the material moreover, it is also possible to "adjust" the wear.
- Metal matrix composite means a material in which hard particles are bound into a continuous metallic matrix, wherein the hard particles are arranged by the continuous metallic matrix separated from each other within the composite material.
- edge protection elements made of a metal matrix composite material are preferably produced by sintering and / or hot isostatic pressing. In the finished material, the non-metallic hard particles are distributed and each surrounded by the metallic material of the metal matrix.
- the metal matrix composite materials therefore differ, inter alia, by the relatively low proportion of hard particles.
- the hard particles of the metal matrix composite materials are significantly larger than the hard particles of hard metals.
- a metal matrix composite material is used in which hard particles of a size of more than 20 ⁇ , z. B. more than 40 ⁇ (preferably more than 60 ⁇ ) and a volume fraction of less than 50% (preferably less than 40%) are used, which are embedded (discontinuously) in a (contiguous) metallic matrix.
- the volume fractions in the (pressed) hard body are meant.
- the edge protection elements are designed as substantially homogeneous solid body, z. As carbide, cermet or MMC.
- the edge protection elements can have a composite structure and in each case a carrier element with an attached or attached thereto.
- the carrier element consists of a ductile material with lower hardness than the wear layer.
- This embodiment has the advantage that the carrier element made of a good material to be processed, for. As steel, can be made, which in particular enables an optimal attachment of the edge protection element on the roll body.
- the wear layer itself then forms the wear protection.
- the wear layer of the edge protection element can, for. B. hard metal or a carbide-like material, eg. As cermet, or - as already described - from a metal matrix composite material (MMC). This wear layer is firmly connected in the course of the production of the edge protection elements with the carrier element, for. By sintering and / or hot isostatic pressing (HIP).
- HIP hot isostatic pressing
- the applied to the carrier element wear layer can cover the entire surface of the support element and thus form the entire surface of the edge protection element. Alternatively, however, the wear layer may cover only a portion of the support element. So there is z. B. the ability to incorporate a recess in the support element, in which the wear layer is then integrated in the sense of a wear insert.
- edge protection elements are inventively releasably attached to the roller body, so that the edge protection elements are basically interchangeable. Such attachment succeeds z. B. by a screw.
- the edge protection elements suitable openings, z. B. bores have, through which corresponding fasteners, z. As screws, can be introduced into the roll body.

- the thickness of the separating web can increase or decrease from the roll edge in the direction of the roll center.
- the recesses and the edge protection elements can each have a cross-section widening at least in the direction of the roll center.
- the cross-section can widen or extend in regions from the direction of the roll end side in the direction of the roll center, so that the (inner) surface of the edge protection elements, which in each case faces the center of the roll in the axial direction, is larger than the (outer) surface facing the roller end face.
- the contour of the recesses or pockets is carried out according to "negative". In this way, the edge protection element itself are positively connected at their outer contours with the roller, so that they are secured in the course of assembly against falling out.
- the invention relates not only to the described press roll itself, but in a preferred development also a roll press with two such press rolls.
- the press roll may be formed as a solid roll, that is, the roll body is formed as a solid body.
- the roller body can also have a (cylindrical) base body and a bandage arranged thereon, so that the wear protection is then mounted on / on this bandage.
- the pocket-like recesses can in the body, ie in the solid body or in the bandage, z. B. be machined by machining to form the partitions.
