Definitions

  • the invention relates to a grinding roller with a roller body and a Variety of wear protection elements made of hard metal, the at least one part form the roll surface.
  • a roller press in which the Roll surface is formed of flat zones, consisting of a highly wear-resistant material, with the spaces between the highly wear-resistant zones with a material of other wear resistance are filled.
  • the interspace material is a sinterable composite material and the highly wear-resistant zones are formed by hot isostatic pressing formed hard body, wherein the space material and the Material of the wear-resistant zones by a hot isostatic pressing process attached to the main body and where the wear resistance of the Interspace material according to a desired, through wear adjusting profiling is substantially slightly higher or lower than the wear resistance of the hard body.
  • the invention is therefore based on the object, a new wear protection concept for the roll surface.
  • the grinding roller according to the invention consists of a roller body and a Variety of wear protection elements made of hard metal, the at least one part form the roll surface.
  • the roll main body also looks in Circumferentially extending recesses, wherein in each recess several wear protection elements in the circumferential direction arranged one behind the other are.
  • the wear protection elements form in this way a quasi closed ring, which offers a high wear protection.
  • the wear protection elements for example, by gluing, staples or Soldering be attached directly to the roller body.
  • the wear protection elements on a Attachment body fastened which consists of a material with lower hardness, especially steel.
  • the holder body is much better than that Edit wear protection element and therefore can in a simple manner be adapted to the roll body.
  • the wear protection elements in the area of the roll edges over the Projecting roll body, they take over the function in this area a dam to the flow of the crushing material in the axial direction avoid.
  • the surface of the wear protection elements can be smooth or be formed profiled.
  • the grinding roller consists essentially of a roller body 10 as well a plurality of wear protection elements 11, 12, 13, 14, ...
  • the Wear protection elements are made of hard metal and form at least part of the Roll surface.
  • the Roll main body 10 extending in the circumferential direction recesses 10.1, 10.2, 10.3, wherein in each recess several wear protection elements in Circumferentially arranged one behind the other.
  • the recesses preferably extend over the entire circumference and are provided at least in the region of the two roll ends 10a, 10b.
  • the Versch andschutzetti are in the circumferential recesses so attached that between two circumferentially arranged one behind the other Wear elements no material of the roll body is present.
  • the distance of the wear protection elements in Circumferential direction on the roll surface less than 5 mm.
  • the length of the Wear protection elements in the circumferential direction is preferably 20-100 mm.
  • the recesses 10.1, 10.3 are dimensioned so that in each recess in axial direction only a wear protection element 11, 13 is arranged.
  • Fig. 2 is a recess 10.2 shown at the end of the roll 10b, in the axial Direction several wear protection elements 12, 14 can be arranged.
  • One Effective edge protection can also be achieved if at the Roll ends only a circumferential recess is provided, in the axial Direction is arranged only a wear protection element.
  • the wear protection elements are rectangular in plan, preferably square educated.
  • any wear protection element to be mounted on a holder body 15, wherein the holder body suitably made of a material with lower hardness, in particular steel consists.
  • the attachment of the wear protection element on the support body can be done for example by gluing, but especially by brazing.
  • the holder body 15 has on its the wear protection element 11th opposite side on a pin 16, with a corresponding complementarily configured bore 10c in the roll body 10 together acts.
  • a fixation can in particular by gluing the pin in the Drilled hole.
  • the circumferential recesses are therefore one of the number the pin provided corresponding number of holes.
  • the arranged on the roll edge wear protection elements 11, 12 are so Aligned that they wear with a page 11a of the Roll surface and with a vertically disposed side 11b a Wear protection for the radially outer edge of a side surface of the grinding roller forms.
  • the support member 15 on the to the side surface of the grinding roller aligned side of the support member also a second wear protection element 17 on the unprotected side of the support member to protect against wear.
  • Adjacent wear protection elements are preferably with such a small Spaced apart that no autogener between them Wear protection is formed.
  • the wear protection elements can also over the entire width of the grinding roller to be ordered.
  • the illustrated embodiment are for the central area Profile body 18 provided (see Fig. 4). These profile body 18, like the Wear protection elements 11 or otherwise formed. They rise up and are preferably spaced such that during the Grinding the material to be crushed in the circumferentially forming Interposed spaces and there forms an autogenous wear protection layer.
  • the wear protection elements can at the roll edge or in the Roll center be arranged flush with the base material, so that in axial direction no profiling results.
  • the to the Roller ends arranged wear protection elements 11 over the surface of the Roller body 10 protrude, as shown in Fig. 4.
  • the Wear protection elements 11 thus form over the entire circumference of the roller a dam, thereby avoiding the flow of crushing material in axial direction (arrow 19).
