Definitions

  • the invention relates to crushing machines with a rotor.
  • Such crushing machines are in different Construction methods and known for various feed materials. So there are, for example, designs in which the supporting body for the crushing tools from an arm cross rotor or also consist of a one-piece rotor body.
  • the hammer crusher is a particularly advantageous design according to German patent 26 05 751, whose rotor of several rotatably attached on a shaft Slices and arranged between them Hammering exists, which are rotatably mounted.
  • the shredding machines mentioned are used for shredding of metallic or non-metallic material or a mixture of these two types of material and consist almost always of a fixed housing, in which the rotor is rotatably mounted.
  • On the inside the housing is usually a so-called Anvil, preferably at the inlet of the housing, the in the case of the hammer breaker according to the patent mentioned the movable striking tools mounted on the rotor or Hammering works together.
  • he is usually with with a rapidly rotating drive coupled rotor a variety of parallel to the rotor shaft, against this but equipped with eccentrically offset axes on which the hammers or rotor tools are freely rotatable are.
  • the crushing takes place through the interaction the rotor hammer with both the fixed anvil at the material inlet as well as with the function of a counter tool possessing housing inner wall instead, against the the material was thrown and at least in one area of the rotor circumference also between this and the shredding tools is crushed or torn.
  • the rotor hammers are in any suitable way on the circumference of the rotor spaced apart.
  • the rotor body consists of a variety of discs, all with the rotor shaft are non-rotatably connected.
  • the invention has for its object an optimization the set-up times, especially different ones Avoid intervals for the exchange. This task is accomplished in a surprisingly simple way the features and measures specified in the main claim solved.
  • active wear parts on the one hand and “inactive” wear parts are spoken on the other hand, then these terms take into account that the Crushing tools, such as the hammers their active crushing work a different wear (active wear) are subject to wear protection other machine parts serving covers, such as for example the protective shields, which are not active on Participate in the crushing process, however, by the whirling around Feed, as mentioned at the beginning, by abrasion and wear impacting pieces of material (secondary Wear of the inactive components).
  • the teaching according to the invention not only leads to a reduction the cost of part manufacturing as well an increase in tool life by making less different Alternating phases of the active and inactive wear parts be achieved, but also opens up diverse Design options for an optimal wear part system. This is particularly advantageous with such Use crushing machines, their rotor from disks, preferably essentially circular Washers.
  • At least one of the two types of wear parts from zones of different material properties like goodness, hardness, toughness and / or Thickness exist. This can be done, for example, through targeted Heat treatment can be achieved. It can thus Cover surfaces or the cover parts of the inactive wear parts (Protective caps) a larger, the wear stronger get resistant hardness as their webs and hubs.
  • the active and / or inactive wear parts releasable and / or are insoluble, so that for the composite for example screws or rivets on the one hand and on the other hand Soldering, welding, gluing, etc. come into question or combinations of these.
  • the sandwich construction is a particularly favorable combination represents, in a further embodiment of the invention at least parts of the wearing parts are executed, for example the hammer overall and from the protective cap only their cover part or top surface.
  • the hammer structure looks like two relative at least hard, wear-resistant layers or layers include a softer one between them, i.e. on both sides attached to the side surfaces of the softer core layer are, then advantageously results in self-sharpening sandwich construction for the hammers, because then the softer core layer on the free end faces wears out faster than the harder outer layers on the side, so that the hammer end in the area of the core receives an indented shape, making the opposite protruding cover layers for a better Shredding efficiency and greater stability to lead.
  • the softer, preferably tough material layers areas are particularly advantageous in Range of those equipped with harder bushings, for example Bearing eyes, made of hammers and protective caps, but also have core layers for the hammers and in the case of the multi-layer composite construction of the cover parts the protective caps have significant advantages, for example as significantly reducing the risk of breakage of the wearing parts Under or intermediate layer.
  • the softer intermediate or Core layer not over their entire two side layers Main surfaces are covered with harder outer layers, rather, the latter can extend to the core layer Have openings, especially only in the side Edge area are provided, preferably also in a shape adapted to the outer hammer contour the recess in the top layer. So that material be saved; the manufacture of this contoured, with Breakthroughs on top layers is by means of laser cutting and / or contour burning easily possible. If in this case the cover layers are preferably on the core layer can be welded on, then additional nor the course of hardness in the edge area Core layer in for the wear behavior of the hammer be influenced in an optimal way.
  • the invention is not limited to one Discs existing rotor 2, but is also in others Carrying bodies of crushing machines, for example an arm cross rotor or a one-piece rotor body, applicable.
  • the shaft 3 can by a drive, not shown be rotated.
  • the disks 4 consist of flanges 4.1 and hubs 4.2 and have holes 4.3 on the same pitch circle lie.
  • the discs 4 lie with their hubs 4.2 on the Shaft 3 close to each other and are at the end of the rotor designed as end plates 4.4 with covers 4.5.
  • the discs form with the hubs 4.2 and the flanges 4.1 4 on the shaft 3 a multi-part rotor or Support body of the rotor 2 for the hammer crusher (Fig. 1 and 2).
  • the active wear parts 7 are on the axle rods 6 rotatable, i.e. freely rotatable, eccentrically mounted and crush in centrifugal position (Fig. 3) in cooperation with one or more counter tools, not shown the housing 1 a not specified here Feed.
  • the inactive wear parts 8 form with their top surfaces 8.1 a substantially cylindrical shell, which the Protects discs 4 from wear.
  • the fastenings or bearings are located the rotatable, active wear parts 7 in Range of intersections f-III, f-VII, f-x, e-I etc. as well the attachment points or brackets of the inactive Wear parts 8 at the intersections f-I, f-IT, f-IV etc. (Fig. 4), or f-I / II, f-IV / V / VI, f-VIII / IX etc. (Fig.
  • the different arrangements of active and inactive Wear parts 7, 8 according to FIGS. 4 to 6 in connection 7 are intended to illustrate that the functional unit Rotor 2 with the active wear parts 7 and the inactive Wear parts 8 during the crushing process in Active and inactive wear according to the invention subject to.
  • the wear is the active wear parts 7 inevitably a multiple wear of inactive wear parts 8.
  • the purpose of the invention is different Wear to match, if possible interpret matching intervals.
  • the invention in their structure, their shape, their Material composition and / or their mutual association the wear and tear during the shredding process adapted active and inactive wear parts 7, 8 to a coordinated, advantageous wear behavior to lead.
  • Joining in composite construction for the purposes of the invention comprises detachable and / or non-detachable Joining agents or types, e.g. Screws, bolts, Dowel pins, rivets, welding, soldering, shrinking, gluing or the like, alone or in combination.
  • This hammer 7 consists of a core layer 7.1 and cover layers 7.2 on both sides and a bore 7.3 for the rotatable, eccentric bearing on the Axle rods 6 (Fig. 1, 2, 3 and 7).
  • the cover layers 7.2 are broken through in the form of the outer contour of the hammer 7, so that the core layer 7.1 in the area of the bore 7.3 and the inner edges of the cover layers 7.2 is exposed.
  • the cover layers 7.2 face the tough or softer core layer 7.1 a larger one Hardness. This is advantageous for the storage area of the Hammer 7 tough and the actual active wear area hard and wear-resistant.
