Definitions

  • the invention relates to a wear-resistant surface armor for the rollers of roller machines, in particular high-pressure roller presses for pressure comminution of granular material, with a multiplicity of outwardly projecting profiles attached to the roller surface at a distance from one another.
  • roller crushers and roller mills In the case of roller crushers and roller mills, brittle ground material is drawn into the roller gap, through which the two rotatably mounted counter-rotating rollers are separated from one another, where it is subjected to pressure reduction.
  • 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.
  • the closed hard outer shell of the armored roller shells can be overstressed by the formation of pressure islands in the roller gap filled with the material to be pressed, with high local point loads on the rollers; Surface cracks can lead to crack propagation in the roller body and / or with a soft underlayer, the welded-on hard profile parts can be squeezed out to the side.
  • the risk that the welded profiled welding beads projecting outward may at least partially break out at high point loads is also not excluded.
  • the invention is based, for the rollers of roller machines, in particular of high-pressure roller presses for pressure comminution of granular goods, an armor that is simple to manufacture, wear-resistant and capable of being pulled in to create, which, despite profiling and therefore good retraction capacity, has a long service life with a minimized risk of cracking even at high point loads.
  • the multiplicity of profiles attached to the roller surface protrude outward from the roller surface with such a great height and are so closely spaced from one another that the gaps or pockets between the profiles during operation of the roller press are filled with one and the same compressed fine-grained material, which remains in the gaps or pockets during the roller revolutions, i.e. the profiles are able to hold the material pressed in between them.
  • the compressed fine-grained material remaining in the gaps or pockets between the roller surface profiles during the roller revolutions can consist of the material to be comminuted by means of material bed comminution in the roller gap of the roller press, which material is stored in these gaps or pockets at the start of the roller press operation and remains there .
  • the spaces or pockets between the profiles of the roller surface can also be filled in advance with a foreign compressed fine-grained material, for example in the building materials area.
  • a suitable binder can also be used to increase the adhesion of the materials.
  • the good pull-in capacity of the press rolls can be increased if neighboring profiles have different heights.
  • the profiles attached to the roll surface can consist of strips which are arranged in the roll axial direction or at an angle of 0 to 90 ° thereto.
  • the profiles can also be made from a multitude of protruding from the roller surface preferably welded studs exist, which are advantageously arranged in a grid pattern on the roller surface such that the distance between adjacent studs is always approximately the same, both in the same row of studs and to adjacent rows of studs.
  • the distance between the adjacent studs is chosen so large that the compressed material remains in the spaces or pockets between the studs during the rotation of the rollers and forms the actual (autogenous) wear protection.
  • This roller surface armoring according to the invention with the hard, wear-resistant nub bolts distributed in the shape of an hedgehog over the roller surface is also able to withstand point-like peak loads, such as can also occur during material bed comminution in the area of the narrowest roller gap of a high-pressure roller press, without destroying the nub bolts To drain the environment as crack-free as possible in the roller base body, which results in the high durability of the roller armor according to the invention.
  • Fig. 1 shows a top view schematically a two-roll machine, for. B. high-pressure roller press for material bed comminution of granular goods, which from above via a feed hopper, not shown the nip between the fixed roller (10) and the loose roller (11) is fed.
  • a plurality of outwardly projecting profile strips (12, 13, 14) are welded onto the surface of the driven rollers (10, 11) which rotate in opposite directions and which are arranged so as to be distributed in a grid pattern.
  • the profile strips could also be arranged on the roll surface in the direction of the roll axis, in a V-shape and the like.
  • a plurality of approximately equal spaces or pockets (15) are formed, which due to the high pressure in the narrowest nip fill up after a short period of operation with the granular material under pressure, which due to the comparatively Small distance between the adjacent profiles (13, 14) preferably less than 40 mm and a profile height preferably greater than 5 mm remains in the pockets (15) during the roller revolutions.
  • Fig. 2 different shapes of profile strips (13, 14) are shown enlarged in cross section.
  • the cross section of the profile strips (16 and 19) is rectangular, the profile strips (17, 18 and 20) trapezoidal, and the profile strip shown on the far right has a circumferential groove (21) on its circumference, so that this embodiment is in operation the roller press not only the spaces or pockets between the individual profile strips with the compressed fine-grained material fill out, but also the recess (21).
  • the profile strips (19, 20, 21) are welded, soldered, glued or the like onto the roller surface (22)
  • the profile strips (16, 17, 18) are anchored in the material of the roller surface (22), e.g. B. by a dovetail groove connection (23).
  • All profile strips (16 to 21) have in common that they consist of a hard metallic alloy material, which allows the formation of sharp edges that would not be achievable by build-up welding beads. In this way, the profile strips with their sharp edges are in a very good position to permanently hold the fine-grained good material that is embedded or pressed in between the profile strips as wear protection for the roller surface (22). This applies particularly to the profile strip (18 / with its undercuts.
  • the adjacent profile strips (24, 25, 26, 27, 28) can have different heights in order to increase the good pull-in capacity of the press rolls.
  • the compressed fine-grained material (29, 30) embedded in the spaces or pockets between the profile strips (24 to 28) during operation of the roller press can be clearly seen, which forms the autogenous wear protection.
  • good material (29, 30) can subsequently be reintroduced by simple pressing for the purpose of repairing or regenerating the rollers.
  • a plurality of is on the surface of the rollers (31, 32) welded out protruding stud bolts (33).
  • the stud bolts (33) are advantageously welded in a grid pattern in such a way that the stud bolt rows (34, 35) applied along the roll surface lines are each offset from one another with a gap.
  • the distance between adjacent stud bolts both in the same stud stud row and to adjacent stud stud rows can always be approximately the same size, so that between the individual stud studs approximately uniform and equally large gaps or pockets (36) are formed, which are formed during the operation of the roller press , ie fill granular goods with good material when carrying out the material bed comminution, the size of these spaces or pockets (36) being dimensioned so large that the material good during the entire rotation of the rollers (31, 32) for the purpose of autogenous wear protection in these pockets (36) remains.
  • Fig. 5 shows an enlarged detail of the vertical section through the stud bolt (33) of Fig. 4 in the welded state.
  • the lower layer of the studded stud (33) and all other studded studs as well as the profiled strips can consist of an annular bandage (37) applied to the base body of the roll and / or of at least one layer of welded-on weld beads lying next to one another.
  • the material of the lower layer (37) is selected so that the stud bolts (33) or profile strips can be welded on well or can be applied using other joining techniques.
  • the stud bolts themselves can have a cylindrical, have a frustoconical or pyramidal configuration.
  • the material of the hard wear-resistant profile strips of Figures 1 to 3 and the stud bolts (33) of Figures 4 and 5 can be made of a metallic alloy with hard materials in the structure, for. B. carbides and / or special carbides exist and / or high carbon and / or high chromium.
  • the profile strips of Figures 1 to 3 and also the stud bolts (33) of Figures 4 and 5 can also consist of hard ceramic material, cemented carbide or the like.
  • the material of the profile strips or stud bolts after welding advantageously has a core hardness of more than 52 HRC (Rockwell C hardness test).
  • the profile strips of Figures 1 to 3 and the stud bolts (33) of Figures 4 and 5 have a height of at least about 5 mm, z. B. 10 mm, and a thickness (diameter) of at least about 8 mm, e.g. B. 15 mm, on, with a roll diameter of at least 500 mm.
  • the invention can be used particularly well for the surface armouring of rollers of high-pressure roller presses for material bed comminution or pressure treatment of ores, including ores containing diamond, which are particularly abrasive goods.
  • the durability of the roller armor according to the invention is high even with such abrasive goods, because only the radially outer surfaces of the profile strips or stud bolts are subject to wear, while the other areas of the roller surface and the profiles applied to them are affected by the self-constructed wear protection layer consisting of compressed good material are protected against wear.
