Definitions

  • the invention relates to a comminution device, comprising: two comminution shafts arranged parallel to one another and having comminution elements arranged thereon, wherein the comminution shafts are preferably rotatable in a mechanically synchronized manner with respect to each other; a shaft-side coupling member connected to a respective first end of the crushing shafts; and a housing having a housing-side coupling element which can be coupled to the shaft-side coupling element.
  • twin-well shredders enjoy a wide application in the comminution of various input materials.
  • These twin-shaft shredders differ from so-called single-shaft shredders in that they have two shredding shafts. The crushing itself is done with the tools on the two shafts to each other, but also against fixed crushing tools.
  • Rotary shears have only so-called cutting discs have the gaps. In the gaps passes the material to be shredded, which is actually cut by the disc of the other wave. The rotary shears have no shredding tools that extend beyond the width of the cutting discs.
  • such two-shaft shredders are used in the waste and recycling industry and in the field of biomass.
  • shredding household waste commercial and production waste of various kinds, Construction site waste, waste wood, green waste and other biomass, but also with iron and other metal scrap.
  • both shredding shafts can be operated with different speeds and directions of rotation.
  • comminution shafts rotate only in synchronous speed and in opposite directions, so the two comminution shafts move towards each other at the same speed or move away from each other.
  • the crushing tools located thereon must be designed so that a mutual contact and thus damage the crushing tools is excluded because the waves can rotate in different rotational speed and direction.
  • the crushing tools can be formed so that the tools of the two shafts interlock, and each of the tools of one shaft, with the tools of the other shaft, perform the crushing, there by the synchronous drive of the crushing shafts, at correct execution of shredding tools mutual damage can be excluded.
  • twin-shaft shredders with synchronous drive once a higher degree of comminution of the input materials is possible, as well a more uniform piece size is achieved by the sieve-like action of the crushing tools on both shredding shafts, than in asynchronously driven twin-shaft shredders.
  • the two-shaft shredders described further here are therefore exclusively those with synchronous drive of the two comminution shafts.
  • twin-shaft shredders with synchronous drive of the shredding shafts have the in Fig. 1 apparent main components of shredding tools. These include the two crushing shafts 1 and 3 with the coupling halves 5 and 7. The two shafts have so-called support elements 9 and 11 which carry the actual comminution tools. As the Fig. 1 shows that are once dividing elements 17 and 19 and the fangs 13 and 15. The main body of the crushing shafts 1 and 3 have additional separating elements 21 and 23rd

  • This two-shaft shredder is the so-called counter rake 31 and 32 of the tines 33 and 34 most different Embodiment is provided.
  • This counter rake is part of such two-shaft shredders.
  • This counter rake once has the task to strip shredded material, which has accumulated between the support disks 9 and 11 of the two shafts 1 and 3 during comminution. This is to prevent a once crushed material from getting back between the crushing waves, and is crushed by these again. Since the two waves reversed in blockages, so change the direction of rotation of each other to each other, uncrushed material would pass from the cutting chamber in the output stream of the crushed material. This should be prevented with the counter rake 31 and 32.
  • the third comminuting element is the regrooving rake 35, which is also referred to as a post-breaking bar.

  • the Nachschneiderechen 35 also carries additional elements 36. Their training is different according to the task of comminution.
  • the task of Nachschneiderechens 35 is to comminute the input material after crushing by the separating elements 17 and 19 of the shafts 1 and 3 in addition, and already shredded material before the counter rake 31 and 32 strip.
  • the reaming rake 35 is subjected to additional comminution by breaking, from which the further term breaking bar also originates.

  • the so-called front movable funnel wall 47 which is fastened to the crushing housing 40 and to the front end wall 41, has to be removed become.
  • a hoist is required because the movable funnel wall of about 450 kg manually remove, does not allow the weight.
  • the Nachschneiderechen 35 is lowered onto the conveyor belt located below the shredder.
  • the service personnel have to go under the crushing housing 40 on the discharge belt lying on his back, and attach the hanger of the hoist on Nachschneiderechen 35.

  • the housing-side coupling element and the shaft-side coupling element can have mutually complementary centering elements. This facilitates merging and aligning the two coupling elements.

In this way, there is a gap in which can fall from the shaft side penetrating parts of the input material, without further to get to the coupling elements.

  • the Figure 10 shows a view in the region of the coupling 119, with the coupling halves 119W on the shaft 102, wherein a shaft 102 has been arranged offset for better view, and the coupling half 119G on the drive side. From this you can see the close fit between the two coupling halves.
  • the coupling half 119G has been provided with an additional centering mandrel 123.
  • a bore has been provided which can receive the centering mandrel.
