Definitions

  • the invention relates to rollers for a high-pressure roller press for material bed size reduction granular good, with a variety of having on the roller surface Distance from each other outwardly projecting profiles.
  • roller crushers and roller mills In the case of roller crushers and roller mills, brittle ground material is placed in the roller gap, through the two rotatably mounted counter-rotating rollers are separated from one another, drawn in and subjected to pressure comminution there.
  • the so-called material bed comminution in the roll gap is also known a high-pressure roller press, in which the individual particles are caused by friction regrind drawn into the nip in a bed, d. H. in between the material bed compressed on the two roller surfaces
  • Application of an extremely high pressure can be crushed (EP-A-0 084 383). It is understood that the roller surfaces are extraordinary are exposed to high stress and wear.
  • V-shaped welding beads on the press rolls of the EP-A-0 084 383 therefore only serve to improve the good collection capacity of the Press rolls and they are unable to do that between them when crushing the bed pressed-in material with certainty, so that the V-shaped Welding beads do not serve to protect the wear of the press rolls.
  • FR-A-767 645 discloses a roll crusher with rolls whose surface has some recesses or pockets distributed around the circumference, which are to be filled with material to be shredded. Significant areas of Roll surface seen in the circumferential direction between the pockets have their original cylindrical surface on and in the area of the narrowest nip, where the roller press pressure is greatest, the material to be crushed presses in the pocket of one (right) roller against the metallic cylindrical surface section the opposite (left) roller, so that at least this cylindrical metallic surface parts of the crushing rollers against wear are not currently protected.
  • This well-known roller crusher is also possible not about wear protection, but through the configuration of the roller surfaces should be from the material to be shredded such.
  • Spiked rolling mills are also known (eg brochure "HEAVY DUTY TOOTHED CRUSHING ROLLS "from Babbitless, published in 1980) for crushing Stones and ores, with roller surfaces that have a large number of teeth, the teeth of the adjacent rollers in the area of the nip for Exercise the crushing effect on gap.
  • the spiked mill could no longer have a crushing effect.
  • An intrusion of the to be shredded There is crushed material in the spaces between the spikes or teeth so not wanted; on the contrary, facilities would then have to be available be the good that undesirably enters the gaps between penetrates the teeth or spines, so that one Spiked roller crusher would be functional again.
  • the spines or The teeth of the spiked roller crusher therefore have nothing to do with wear protection.
  • FR-A-2 164 120 discloses ribs or other protrusions Rolling mill rolls for the treatment of soft, tough materials such as B. cocoa masses or chocolate masses, which through the ribs or other projections to be cut and tumbled again and again. In this well-known Rolling mill is not about the problem of roll wear.
  • FR-A-2 057 414 discloses a coal briquette press with on the roll surface arranged briquette troughs for the production of coal briquettes from large Lump of coal. So this is a material shaping and compression process, and the briquette troughs of the rollers are not used to protect against wear, but the material shaping. In the briquette depressions is said to be straight no material is left behind, on the contrary, the shaped ones should Charcoal briquettes from all mold troughs immediately after passing through the good material loosen through the narrowest nip.
  • pages 144 and 145 are protective measures against a sliding wear stress known, as in particular in the case of ground-moving machines such as B. occurs in digging excavator buckets. From the the latter publications it is known on the walls of excavator buckets so-called "studs" to weld, then when sliding such Excavator bucket through a grain pile covering the spaces between fill the "studs" with the clearing material itself as it is.
  • the clearing material is just digged into the spaces between the "studs” because the excavator bucket only translates, in no case, however, a rotational movement and certainly not a high-pressure pressing movement.
  • the excavator bucket only translates, in no case, however, a rotational movement and certainly not a high-pressure pressing movement.
  • the excavator bucket In the well-known "studs" of the excavator buckets, one can Stress in the direction of the blade circumference occurs, but not a high stress in the radial direction, especially not at a height of greater 50 MPa pressure or the equivalent of more than 2000 kN / m roll length, which at the Material bed shredding in the area of the narrowest nip of the press rolls acts on the regrind, which increases the risk of wear on the press rolls results.
  • the invention is based, for a high-pressure roller press the task to Material bed crushing of granular good simple press rolls to create, which are highly wear-resistant, without reducing their pull-in capacity is.
  • roller formation are able to take the pressed in between them and after High-pressure material bed shredding agglomerated material certainly always to hold as a compact.
  • Good material an ideal autogenous wear protection.
  • the profile body can also, in contrast to build-up welding beads, easily be formed with sharp edges with which it is stored between them Being able to hold on to good material even better.
  • the spaces or pockets between the profile bodies are in advance with a foreign compressed fine-grained good material filled in in the building materials area z. B. with a cement clinker / plaster mixture or in the ore area z. B. with highly wear-resistant ceramic material, which remains in the spaces or pockets.
  • a suitable one Binder to increase the adhesion of the materials used come.
  • the profile bodies attached to the roller surface can be made from profile strips exist, which are distributed on the roller surface in a grid pattern are arranged.
  • the press rollers can still pull in well can be increased if adjacent profile strips have a different height exhibit.
  • the profile body can also be made from a variety of from the roll surface protruding stud bolts exist on the roller surface are arranged in a grid pattern such that the distance between adjacent Stud bolts both in the same stud stud row as well as to neighboring ones Stud rows are always about the same size. This solution also remains the compressed material during the rotation of the rollers in the Spaces or pockets between the stud bolts and forms the actual one autogenous wear protection.
  • Fig. 1 shows a top view schematically High pressure roller press for Good bed crushing of granular goods, which of above about a good job, not shown Nip between the fixed roller (10) and the loose roller (11) is fed.
  • the driven counter-rotating rollers (10, 11) is a variety of outwardly projecting Welded profile strips (12, 13, 14), which intersects in a grid pattern are arranged.
  • the profile strips could also be in roller-axial direction, in a V-shape and the like be arranged on the roller surface.
  • FIG Shapes of profile strips (13, 14) shown are shown. So is the cross section of the profile strips (16 and 19) rectangular, the profile strips (17, 18 and 20) trapezoidal, and the profile bar shown on the far right has a circumferential groove on its circumference (21), so that in this embodiment in Operation of the roller press not only the gaps or pockets between the individual profile strips with the compressed fine-grained material fill out, but also the recess (21) to. While the profile strips (19, 20, 21) on the roller surface (22) is welded, soldered, are glued on or the like, they are Profile strips (16, 17, 18) in the material of the roller surface (22) anchored e.g. B. by a dovetail groove connection (23).
  • All profile strips (16 to 21) have in common that they are from a hard metallic alloy material, which the formation of sharp edges allows would not be achievable by surfacing. In this way, the profile strips with their sharp edges very well able to between the the profile strips stored or pressed fine-grained good material permanently as wear protection for the roller surface (22) to hold. This applies in particular to the profile strip (18) their undercuts.
  • the stud bolts (33) are in a grid pattern welded with advantage such that the rows of stud bolts applied along the roll surface lines (34, 35) each gap to each other are staggered.
  • the distance Adjacent studs in both the same stud row as well as to neighboring rows of studs always be about the same size, so that between the individual studs are approximately uniform and interspaces of equal size or Bags (36) are formed, which during the Operation of the roller press, d. H.
  • the size of these spaces or pockets (36) is dimensioned so large that the good material during the entire rotation of the Rollers (31, 32) for the purpose of autogenous wear protection remains in these pockets (36).
  • Fig. 5 shows an enlarged detail of the vertical section through the stud bolt (33) of FIG. 4 in the welded state.
  • the lower class of the Stud bolts (33) and all other stud bolts as well as the profile strips can be from one to the Ring body applied to the roller body (37) and / or from at least one layer next to each other welded weld beads exist.
  • the material is the underlayer (37) selected so that the stud bolts (33) or weld profile strips well or by means of other connection techniques applied.
  • the studs themselves can be cylindrical, frustoconical or pyramidal Have configuration.
  • the material of the hard wear-resistant profile strips of Figures 1 to 3 and the studs (33) of Figures 4 and 5 can be made of a metallic Alloy with hard materials in the structure, e.g. B. Carbides and / or special carbides exist and / or be high carbon and / or high chromium.
  • the Profile strips of Figures 1 to 3 and also the Studs (33) of Figures 4 and 5 can also made of hard ceramic material, cemented carbide or the like exist. In any case, the material shows the profile strips or stud bolts after Welding with advantage a core hardness of more as 52 HRC (Rockwell C hardness test). With The profile strips of Figures 1 to have advantage 3 and the stud bolts (33) of FIGS.
  • the invention is particularly well applicable to surface armor of high-pressure roller press rollers for material bed crushing or pressure treatment of ores, including ores containing diamonds, which represent particularly abrasive goods.
  • the service life the roll armor according to the invention even with such abrasive goods because only the radially outer surfaces of the profile strips or stud bolts are subject to wear, while the remaining areas of the roll surface and the profiles applied to it by the self-made from compressed material existing wear protection layer against wear are protected.
