Definitions

  • the invention relates to a process for the reprocessing of a used grinding roller of a high-pressure good bed roller mill according to the preamble of claim 1.
  • Milling rolls of this type are known, for example, from EP 0 516 952 B1. They contain a plurality of wear-resistant profile body, which are incorporated with part of their length in holes of the roller body and protrude with the remaining part of its length over the surface of the roller body. In the operation of such
  • Rolls fill the spaces between the protruding profile bodies with the good bed roller mill abandoned crushed material, which thus provides a certain autogenous wear contactor for the surface of the roller body.
  • Roll surface forming material of the roll body is greater than 56 HRc (hardness according to Rockwell). This grinding roller is used in the crushing operation until a substantial part of all profile body has worn out completely and / or has fallen out of the roll body. The reprocessing of the used grinding roller is then carried out in such a way that the roll surface is brought back into a cylindrical shape by completely turning off the profiled body and the original holes, after which new holes are produced and inserted into these holes new profile body.
  • the invention is therefore based on the object, a method according to the preamble of claim 1 in such a way that a cost-effective reprocessing of a used grinding roller is achieved.
  • the worn surface of the roller body is turned off at least in a partial region of the width of the roller body when a certain state of wear is reached. Then, in a welding process, a material layer for increasing the diameter is applied at least to the turned-off surface.
  • the welded material layer is then with
  • these bores can either be provided only in the welded-on material layer or extend into the base material of the roller body lying beneath this material layer.
  • the worn surface of a roller body can be equalized even with different degree of wear of the individual sections with the least possible material and labor.
  • the inventive method is thus characterized by a time and material-saving, cost-effective reprocessing of a used grinding roller.
  • Fig. 1 shows (in a schematic longitudinal partial section through the roller) left the new condition of the roller.
  • the roller body 1 is provided with a plurality of holes 2,
  • Fig. 1 shows right the worn state after a certain period of operation.
  • Fig. 2 illustrates how a used grinding roller according to a first variant of the method according to the invention can be worked up again.
  • the worn state of the roller body 1 'already described with reference to FIG. 1 and the profile body 12', 13 ', 14' are shown.
  • the worn profile bodies 12 ', 13', 14 ' are first removed.
  • the worn surface l 'a of the roller body 1' is turned off to a diameter D.
  • Diameter D in this embodiment is smaller than the diameter of the bottom of the holes 2, 3, 4. These old holes are thus completely removed by the twisting.
  • Welding process applied a layer of material 16 to increase the diameter. This material layer 16 is then provided with holes 22, 23, 24 for receiving new profile body 32, 33, 34.
  • the worn state is shown on the left again and the state after reprocessing is shown on the right.
  • the differently worn surface l' a of the roll body 1 'in the edge regions of the width of the roll body ie here in the areas in which the profile body 12', 13 'were turned off (except here in the region of the profile body 14') to the diameter D 'of the most heavily worn portion.
  • a plurality of layers of a material layer 26 are then applied to the resulting, largely leveled surface 1 'c in a welding process. Thereafter, this material layer 26 is provided with holes 22, 23, 24, in the new
  • FIG. 4 shows a modification of the variant according to FIG. 3.
  • material layers 26a, 26b, 26c are applied to the leveled surface 1c of the roll body 1 ', which is viewed over the width of the roll body 1' - may have different hardness, thickness and wear properties. In particular, it is possible to take account of the different wear stresses which occur in operation in the individual subregions of the width of the roller body.
  • Holes 22, 23, 24 are provided for receiving the new profile body 32, 33, 34 exclusively in the welded-on material layer 16 or 26 or 26 a, 26 b, 26 c
  • Fig. 5 shows a variant of the embodiment of FIG the holes 42, 43, 44 for receiving the new profile body 32, 33, 34 are passed through the welded material layer 26 'and into the under this
  • Material layer 26 'extending base material of the roll body 1' extend.
  • the thickness of the welded-on material layer 26 ' can be kept significantly smaller than in the variant according to FIG. 3.
  • Rolling body must have uniform diameter. It can be rather for individual partial areas of different diameters are selected, for example, when the edge area is only slightly worn and therefore no welding is carried out here.
