Definitions

  • the present invention relates to a receiving arrangement of a breaking tooth on a crushing roller of a crusher, wherein the crushing tooth at least partially protrudes from the surface of the crushing roller for generating a refractive effect.
  • Crushing rollers can be equipped to produce a refractive effect directly with crushing teeth, but often crushing rollers are also equipped with so-called crushing plates on or on which the crushing teeth are attached to produce the refractive effect.
  • the crushing teeth protrude beyond the surface of the crushing roller or of the crushing plates in order to generate a crushing action against a crushed material by a rotation of the crushing roller.
  • two crushing rollers are arranged parallel to each other and set in rotation, and the crushed material is placed in a gap between the two crushing rollers in order to achieve the crushing effect on the crushed material.
  • Crushers in the context of the present invention thus relate to crushers with rather slowly rotating crushing rollers, which achieve a crushing effect while producing very high refractive powers.
  • Crushers in the context of the present invention thus also relate in particular to so-called sizers.
  • the receiving arrangement of a crushing tooth to a crusher relates both the recording of the crushing tooth on a crushing plate, which in turn is attached to the body of the crushing roller, as well as the inclusion of the crushing tooth on the body of the crushing roller itself
  • the term crushing roller used below therefore always includes the term of the crushing plate.
  • the crushing teeth are often mounted on the crushing roller in such a way that the crushing teeth can be disassembled once a degree of wear has been reached.
  • the crushing processes can cause very high loads, both central and oblique, on the teeth.
  • the oblique loads on the crushing teeth place high demands on the strength of the crushing teeth and the receiving arrangement for attaching the crushing teeth on the roller or on the crushing plate, but the receiving arrangement should take as little as possible space, and the crushing teeth can not, for example, with their tooth root basically be taken very deep in the crushing roller.
  • the recording geometries on the crushing roller should be possible with little effort and few machining steps to produce, and there should be an easy accessibility of the processing surfaces.
  • crushing rollers are known, which must be coated at regular intervals, so that the accessibility of the crushing plates must be given to the armor.
  • Recording structures for the arrangement of the crushing teeth on the crushing roller, which protrude from the surface of the crushing roller, should be avoided.
  • the materials of the crushing teeth are nowadays formed for reasons of wear by highly hard materials, which are extremely expensive in the machining. These include hard metals, ceramics, high-strength steels and combinations thereof.
  • DE 41 23 967 A1 shows a receiving arrangement of a breaking tooth on a crushing roller of a crusher, and the crushing teeth are screwed from the rear side of the crushing plates.
  • the crushing plates have a receiving structure which protrudes above the surface of the crushing roller, so that the disadvantages described above arise.
  • EP 0 640 396 B1 shows an impact crusher with a rotor which has blow bars which are fastened by one or more clamping wedges in blow bar receivers of the rotor.
  • the blow bars have root portions which extend into a receiving pocket in the crushing roller and are keyed with a clamping wedge.
  • such an arrangement is only feasible using another component which forms an abutment bar, which is arranged at the edge of the receiving pocket by carrying out thermal joining processes.
  • the receiving arrangement of the blow bar is designed very expensive, and with impact crushers significantly lower maximum forces on the over the surface of the crushing roller protruding tool areas, so that an arrangement of a blow bar can not be further developed to Brechzähne on the crushing roller of a crusher or a sizer on the same or similar manner.
  • the blow bars are formed over the entire crushing chamber width, very small oblique loads act in comparison to the breaking teeth of a crusher.
  • the object of the invention is the improved design of a receiving arrangement of a crushing tooth on a crushing roller of a crusher, the receiving arrangement should be as simple as possible to be produced with minimal processing steps in the crushing roller or in a crushing plate, and the arrangement of the crushing tooth on the crushing roller should as possible withstand high loads, however, the crushing tooth should be as easy and fast replaceable.
  • the invention includes the technical teaching that in the crushing roller, a receiving pocket is introduced, wherein the crushing tooth has a tooth root which extends into the receiving pocket, and wherein at least one clamping means disposed substantially below the surface of the crushing roller and received in the receiving pocket is through which the tooth root is clamped in the receiving pocket.
  • the solution according to the invention thus consists in a laying of the receiving arrangement under the surface of the crushing roller, and an additional mounted on the crushing roller holder deleted.
  • machining operations can be easily performed below the surface of the crushing roller without taking any annoying raised structures into account.
  • the simple design of a receiving pocket, which is open at the top, ensures easy accessibility of the processing zones. An armoring of the plates can be carried out with little effort.
  • the receiving pockets for receiving the refractive teeth over their tooth roots may have rectangular recesses with a, for example, flat bottom of the bag, and the machining of the receiving pockets is thus carried out in a very simple manner by a milling operation. For example, a single milling operation may be sufficient to form a receiving pocket in the crushing roller or crushing plate.
  • the load capacity of the breaking teeth and the receiving arrangements with respect to obliquely introduced loads can be greatly increased.
  • the teeth for simple versions of crushing rollers by cutting, such as a thermal burnout can be provided from a thick sheet steel, as well as in the receiving pockets but also highly coated teeth with Hard metal, ceramic or other materials are included in the receiving pockets.
  • the crushing tooth is, as it were, extended by its crushing root, which extends below the surface of the crushing roller, and a mechanical wedging of the tooth root can take place within the receiving pocket.
  • the very high loads occurring can be introduced directly from the crushing tooth on the tooth root in the crushing roller without screw or other connection means must be formed to accommodate the high forces.
  • Replacing the crushing teeth can be done manually or robotic within a very short time.
  • the robotic means can both operate the clamping means, for example, loosening and tightening the clamping wedge or the wedgelock, as well as a removal and insertion of the crushing tooth in particular make fully automated.
  • the tooth root of the crushing tooth and the clamping means can be introduced adjacent to each other in the receiving pocket.
