Definitions

  • the invention relates to a grinding roller for granular pressure reduction Good, especially for roller presses for material bed shredding, with one Roller jacket with wear-resistant surface armor that alternates Zones of highly wear-resistant material and intermediate zones other wear resistance.
  • the invention also relates to a Process for producing the grinding roller.
  • roller mills In the case of roller mills, granular, brittle ground material is placed in the roller gap, through the two rotatably mounted counter-rotating rollers are separated from each other, drawn in and there a pressure comminution subject.
  • material bed crushing is also known in the Roll nip of a high-pressure roller mill or roller press in which the individual particles of the frictionally drawn into the nip Grist in a bed, d. H. in one between the two roller surfaces compressed material filling when using a high pressure can be crushed. It goes without saying that the roller surfaces of a high load and a high Are subject to wear.
  • roller surfaces have at least the following requirements : They should have a high wear resistance, can be produced inexpensively by the operator or Customers can be repaired, and also good feed behavior for possess the goods to be shredded.
  • EP-B-0563564 is a grinding roller for a material bed roller mill known in which the roller shell made of a wear-resistant Chilled cast iron exists. Thereby are on the outer surface of the chilled cast iron jacket Profiled welding beads welded on, which cross can, so that then a diamond-shaped weld bead grid pattern for the purpose of achieving autogenous wear protection. Except that it is problematic to weld chilled iron properly, especially if the hard cast material contains a high proportion of carbon, Contains chromium etc, is the production of this chilled cast iron roll cover subsequent special build-up welding is complex. The service life the build-up welding bead is limited.
  • the invention is based on the object, in particular for the grinding rollers of high-pressure roller mills or roller presses for pressure reduction granular good one for the autogenous wear protection with application surface armor suitable for raster armor technology to create a high through wear and pressure resistance Has durability and yet relatively simple and overall is inexpensive to manufacture and repair.
  • the recesses of the roller shell can be circular, elongated, polygonal, Rectangular, square or also shaped like a circle with tips in the circumferential direction of the roller or also with tips in the axial direction.
  • these recesses are corresponding prefabricated, highly wear-resistant hard bodies especially made of sintered metal. The reason of the deepening and the bottom of the hard body are z. B.
  • the tool for performing the adhesive printing process can be a hydraulic one or mechanical press. It is particularly advantageous the tool is a hot one put over the fitted hard body Shrink ring, which is at a temperature of z. B. 200 ° C has been heated and which after cooling, d. H. after its shrinkage from the pressed hard bodies is removed again, for which purpose as a tool serving shrink ring from at least two parts z. B. two ring halves is composed.
  • the shrink ring which serves as a tool, performs its function of pressing the hard body well into the recesses of the roll shell can and the shrink ring on the tops of the hard body to be pressed Fits tightly, it can be advantageous that the shrink ring on his Inside in the zones opposite the hard bodies to be pressed, corresponding radially inward elevations has, in the same shape as the hard metal body to be pressed.
  • the adhesive can Production of the adhesive connection between the hard bodies and the Because of the depressions with hard metal splinters such. B. hard metal carbide chips be provided, whereby the strength of the adhesive bond is still increased.
  • the surface armor according to the invention is highly wear-resistant and but comparatively easy to manufacture. Should be in the operation of the roller press or Gutbett roll mill an adhesive connection of a hard body can solve the roller surface in such a case of damage be repaired by the operator himself.
  • the clearance zones of the roll shell between those fitted in the roll shell recesses Hard bodies can be in operation when the roller machine through the entrance protected auto wear protection against wear become.
  • Figure 1 are in the outer surface of a roll shell 10 from each other spaced depressions 11, 12 molded.
  • highly wear-resistant hard bodies 13, 14 are fitted, which also rise above the outer diameter of the base body can.
  • the hard bodies can consist in particular of sintered metal and they can z. B. a cylindrical To have shape.
  • the diameter of the hard body 13, 14 can, for. B. 70 mm amount, and the smallest distance between adjacent hard bodies from each other can at the parting lines 20 z. B. 20 mm.
  • the reason 15 of the wells 11, 12 and the underside 16 of the hard body 13, 14 are with of a certain surface roughness, so that the two surfaces do not lie snugly on each other, but small between the two surfaces Cavities have been formed.
  • the hard metal plates 13, 14, which according to the top view in FIG. 2 are cylindrical 3, but can also be rectangular according to FIG. 3, polygonal, square or according to FIG Circumferential direction as well as according to FIG Axial direction, etc.
  • roller jacket 10 of the grinding roller is a cast metal body, so it can also be made from at least two different liquid casting compounds be produced in a single casting process.
  • composite casting the at least two casting compounds are distributed so that in the outside area of the roll shell a harder metal casting compound and in the radial inner area concentrated a softer metal casting compound of the roller shell become.
  • the metal casting compounds can be coordinated with one another that there is good material compatibility in the mixing zone area and none Tensions occur.
  • the entire roll shell 10 can be centrifugally cast be made, in the appropriate form first the harder metal casting compound and then the softer and tougher one Cast metal casting. At the same time this composite casting in the outer surface of the roll shell 10 Indentations 11, 12 are formed, thereby machining the Roll jacket is not required.
  • the one located in the outer region of the roll shell 10 Cast material can advantageously have a hardness of more than 55 HRC (Rockwell C hardness test).
  • the cast material can be chrome-alloyed and also special carbides and other hard alloy components
