Definitions

  • the invention relates to rollers for roller machines, in particular for high-pressure roller presses with two rotatably mounted rollers which rotate in opposite directions and are separated from one another by a nip for pressure comminution of granular material.
  • roller crushers and roller mills In the case of roller crushers and roller mills, brittle ground material is drawn into the roller gap and subjected to pressure reduction there.
  • material bed comminution in the nip of a high-pressure roller press in which the individual particles of the ground material drawn into the nip by friction in a material bed, ie. H. are crushed in a material bed compressed between the two roller surfaces when an extremely high pressure is applied (EP-PS 0 084 383). It is understood that the roller surfaces are subjected to extremely high stress and wear. It is therefore known to armor the roller surface by welding weld layers of hard metallic materials onto the roller base body or by connecting a one-piece or multi-part wear-resistant jacket made of cast or rolled material to the roller base body.
  • Fig. 1 shows as a prior art detail of the top view of a high-pressure roller press with two rotatably mounted counter-rotating rollers (10, 11) which are separated from each other by a nip (12) in the granular material using a very high pressure the material bed crushing described above is subjected.
  • the roller shells In the original new state, the roller shells have a cylindrical surface, which is indicated by the dashed lines (13, 14). The roller surfaces are armored against wear.
  • the trough-shaped or trough-shaped wear profile (15) of the roller (10) or (16) of the roller (11) described above is formed during operation of the high-pressure roller press, that is to say the rollers wear on the side Edge areas (17, 18) and on the opposite edge areas are not as strong as on the other surface areas.
  • roller gap (12) resulting from the wear profiles (15, 16) does not become uncontrollably large during the operation of the roller machine, for the purpose of adjusting the roller gap, without the rollers touching inadmissible ways at the peripheral points that are not so badly worn , the components that remain on the side of the roller and have not yet worn out (17, 18) (as well as on the corresponding opposite roller edges) are artificially ground or otherwise removed.
  • the volume of material to be abraded or removed or the lateral bead is indicated at (18) by left hatching.
  • the invention is based on the object of designing rollers for roller machines, in particular for high-pressure roller presses, in such a way that the lateral beads or trough-shaped wear profiles of the roller surfaces described above do not occur, or only after a very long operating time.
  • the rollers according to the invention have wear-resistant roller armor, be it welded armor or a cast or rolled one-part or multi-part wear-resistant roller jacket.
  • the wear-resistant roller surface designed so that the lateral parts of the wear-resistant roller surface located in the region of the roller ends wear out more quickly and this higher wear counteracts the formation of the lateral beads on the roller surface.
  • this can be done by deliberately welding or welding in less wear-resistant materials or material welding layers in the lateral roller end regions. This applies both to the new production of a wear-armored roller and to the regeneration of such a roller after it has worn out.
  • rollers have a cast, wear-resistant surface armor
  • the cast material e.g. B. on the basis of chilled cast iron, made less wear-resistant in the lateral roll surface end areas by locally introduced heating (tempering) than in the other areas of the surface armor.
  • roller armor in the lateral end regions Pour less wear-resistant materials into the armor.
  • Fig. 2 shows a wear-resistant roller (19) with a cylindrical outer contour, at the two ends of which there is a transition region (20a, 20b), in which towards the roller end faces (21a, 21b) Roll diameter decreases, linearly or domed outwards.
  • the advantage of the rollers according to the invention for the operation of the roller machine is that an adjustment of the roller geometry required by grinding the roller surface can, if at all necessary, be reduced to a minimum.
  • the useful life of the wear-resistant roller armor is extended in the rollers according to the invention.
  • the costs and the availability of the roller machine are influenced favorably when using the rollers according to the invention.
