Definitions
- the invention relates to a roller press with two rotatably mounted press rollers, between which a nip is formed, in which the material to be processed is guided, wherein the nip is front side (or laterally) limited by limiting plates, the boundary plates each having a base plate and a wear protection layer attached to the base plate, wherein the wear protection layer is formed at least in a first wear zone (with high stress) of individual wear protection elements (at least partially) made of a wear-resistant material with respect to the base plate greater hardness.
- This roller press is used in particular for the comminution of material, in particular of highly abrasive material, eg. As ore, cement clinker, slag, kimberlite, coal or ceramic bases.
- a roller press for high pressure crushing is also referred to as a good bed roller mill.
- the invention also relates to roll presses for the compaction or briquetting of material. Always occur in the processing of material, eg. As in the crushing of brittle, granular material, high forces and the roll surfaces are heavily stressed, so that the wear protection of the roll surfaces in practice is of particular importance. Thus, for the wear protection of the roll surfaces z.
- boundary plates delimiting the nip laterally are subject to high stresses and heavy wear, so that they are provided with a wear protection layer.
- Such boundary plates are also referred to in practice as "cheek plates”. They delimit the roller gap which tapers in a funnel shape in the direction of rotation of the press rolls or in the conveying direction laterally or roll frontally.
- a roller press with such lateral boundary plates or Mahlgut exchangesblechen is z. B. from DE 10 2007 032 177 B3.
- a boundary plate z. B. applied a continuous wear protection layer by build-up welding or other means on the base plate or attached to this.
- a first wear zone which relates in particular to the region of the minimum gap width of the nip, occur in the particularly high forces to provide a wear protection layer of individual wear protection elements.
- It may be a variety of plate-shaped wear protection elements (tiles), the z. B. of a wear-resistant composite material, for. B. made of hard metal, are made and attached in a tight arrangement next to each other surface on the base plate, z. B. by soldering.
- the use of such boundary plates or cheek plates with a tiled, wear-resistant surface has basically proven itself in practice. At high forces in particularly critical areas, however, it can lead to chipping of individual parts of the tiles and this in turn provides targets for further outbreaks, so that solutions with tiled structure are fundamentally capable of further development. - This is where the invention starts.
- WO 2014/209417 A1 discloses a roller press with adjustable, lateral limiting elements.
- limiting elements can also be provided in which pin-like wear protection elements are displaceably arranged in sleeve-shaped holders, so that the wear protection elements are arranged displaceably in the holders, in order, for. B. to be able to adjust the supernatant of the wear protection element on the bracket beyond.
- the invention has for its object to provide a roller press of the type described above, in which in the region of the lateral boundary plates or cheek plates damage the wear protection layer reliably avoided.
- the wear protection layer in the area of the cheek plates should be distinguished by a particularly high durability and consequently optimum wear protection.
- such a boundary plate should be provided.
- the invention teaches in a generic roller press of the type described above that the Verschl comprehensive protection- elements are designed as pin-shaped wear protection elements and consequently as pins (ie wear protection pins) that the base plate in the first wear zone a plurality of individual, in the base plate has incorporated (only front open) recesses and that in the recesses (or in each recess) each have a single wear protection pin is inserted with its full length such that the pins do not project beyond the recesses out.
- the pins are (substantially) flush aligned in the recesses
- the pins have a length which corresponds (substantially) to the depth of the recesses.
- the recesses have a different depth and in this case it is useful if the lengths of the pins is adapted to the respective depth of the recess, so that overall the preferred flush aligned arrangement is realized.
- the recesses are preferably separated from one another by separating webs which surround the respective recess in full or in part.
- the pins are inserted with their full length in the recesses so that the pins do not protrude beyond the dividers out of the recesses. It is preferably provided that the pins (with their front surfaces) terminate flush with the separating webs, so that the pins or their front surfaces and the surfaces of the separating webs form an aligned and consequently uniform, flat surface.
- the invention is based on the recognition that the possibly occurring in boundary plates with a tiled surface chipping can be reliably avoided in a simple manner when a wear layer is made of a variety of pin-like wear protection elements, but the pins do not rest laterally against each other, but each independently in a variety of recesses, z. B. holes, fully supported and thus stabilized. Since each pin is supported in a single hole over the full circumference and the full length, there is no risk of chipping and thus form no points of attack for further destruction of
- pins can be used on fundamentally known findings.
- wear protection pens which are also referred to as "studs” come in practice for a long time in the field of roll surfaces of press rolls for crushing brittle material used.
- studs In the area of such roll surfaces, however, it is essential that the pins protrude beyond the main body of the roll so that an autogenous wear protection is formed by the material to be shredded in the region of the intermediate spaces.
- the pins in the region of the lateral boundary plate, it does not depend on the formation of such autogenous wear protection, so that the pins do not protrude beyond their limiting surface.
- any bending loads of the pins are avoided and this in turn means that pins made of particularly hard material can be used, since they must withstand no bending loads.
- a particularly close arrangement of the pins can be realized, ie the pins are arranged as close to each other as possible close together to obtain a full-surface wear protection layer of these pins.
- the wear protection pins are therefore used in the lateral boundary plates according to the invention due to other considerations and in a different arrangement than in conventional "Studlining" surfaces of press rolls.
- the recesses on the one hand and the pins on the other hand are preferably cylindrical.
- the recesses can z. B. can be formed as holes and preferably as blind holes. It is advantageous if the base plate of a ductile metal, for. B. made of steel.
- the recesses are integrated directly in one piece in such Grundplatter, z. B. by machining, preferably by drilling, milling or the like.
- the wear protection pins are preferably made of a wear-resistant multiphase material, eg. B. made of hard metal. It is a non-oxidic material based on hard material in the form of an intermetallic (intermediate) phase, which consists of a hard material and a binder phase.
- binder or binder phase is cobalt (Co).
- pins can be used with a particularly high hardness, since the pins are subject to the described reasons no bending stress.
- cobalt content can be used.
- the pins are completely inserted into the recesses (preferably exactly matched in diameter) and held in a form-fitting and / or frictional engagement in the recesses by the pins z. B. are pressed into the recesses.
- the pins are preferably arranged particularly close to the base plate. It follows that the recesses surrounding and the individual recesses of a separating dividers in the region of the minimum thickness are particularly narrow. In this case, the minimum thickness may be less than half the diameter of the recesses themselves.
- the recesses and, accordingly, the pins can z. B. a diameter of 6 mm to 20 mm, z. B. 10 mm to 20 mm, z. B. 14 mm to 16 mm.
- the dividers can have a minimum thickness of less than
- the pins as pin-shaped wear protection elements have a length (that is to say the initial length) which is greater than the diameter of the pins, preferably more than 1.5 times the diameter, z. B. more than twice.
- the length of the pins is z. B. 10 mm to 50 mm, preferably 20 mm to 40 mm. With a diameter of 10 mm, the length z. B. 16 mm or at a diameter of 35 mm z. B. 53 mm.
- the recesses, z. B. are formed as holes, preferably have a flat or flat bottom. Furthermore, it is expedient if the pins have a surface facing away from the wear surface, which is also flat or planar.
- this embodiment is limited only to a spatially limited, first wear zone covering the area of the nip with a minimum gap width.
- first wear zone covering the area of the nip with a minimum gap width.
- the boundary plate has a second (larger) wear zone covering the area outside of said first wear zone.
- This second wear zone which covers in particular the region above the first wear zone in the gap which widens counter to the direction of rotation, can be, for example, B. be equipped with conventional wear protection elements in the embodiment as a plate-shaped tiles or with a surface buildup welding.
- Plate-shaped tiles means plate-shaped wear protection elements whose diameter or width is greater than their height or thickness. In particular, it can be polygonal tiles. However, these tiles are not individually arranged in individual recesses in the second wear zone, but flat next to each other in a flat depression of the base plate.
- the invention also relates, moreover, to a delimiting plate for a roller press of the type described.
- the limiting plate according to the invention which is equipped with the pin-shaped wear protection elements, is also placed under protection on its own. All variants and options that are explained in connection with the roller press, can therefore be realized even with the isolated under protection provided boundary plates.
