  • the breaking waves 20, 22 are in FIGS. 6 and 7, respectively shown in cross section. They are made of one with longitudinal grooves 24 provided cylindrical full cylinder as the core body 21 formed, in which longitudinal grooves 24 on both sides tapered or T-shaped break or blow bars 26, 27 are used with breaking edges 27 which of clamping means 28 using screws 29 are held.
  • Crushing device 10 has on its crusher 12 a feed hopper 30, via which the feed to be fed Shredding material the crushing rollers 20, 22 is supplied and thereby as a result of the intended Inclined due to gravity on the crushing gap 23 moved between the crushing rollers 20, 22.
  • a metering shaft located above the crushing rollers 32, each along a circumferential surface Screw line is provided with drivers 33, ensures thereby for a continuous feeding of the shredding material 34 according to its nature in terms of size and strength as well as in the correct dosage in order to avoid malfunctions as a result of jamming of the Crushing rollers 20, 22 safely excluded. In addition it ensures a material build-up that prevents dust should prevent.
  • the removal device 16, which is below the crusher 12 connects, is preferably as a belt conveyor trained, but instead a screw conveyor, a vibratory conveyor or the like.
  • Fig. 2 the crusher 12 is in cross section, the means transversely to the longitudinal sectional view shown in FIG. 1, reproduced, from this representation it can be clearly seen that the breaking waves 20 with on both sides tapered crushing or blow bars 26 are provided, which are directed radially outwards and have a rectangular cross section.
  • the drivers 33 cover the entire circumferential surface of the metering shaft Cover 32 so that the shredding material to be fed 34 is always detected safely.
  • each of the breaking waves 20 is a contour sieve element 36 modeled on the breaking waves 20, which in a variably adjustable distance is pivotable and fixable, as in particular from the 4 is shown schematically.
  • Fig. 4 the arrangement of the crushing waves 20 and the metering shaft 22 and the sieve elements 36 is shown in a schematic side view, here the relative adjustability of the crushing waves 20 to each other according to the horizontal arrow s H and the metering shaft 32 to the crushing waves 20 corresponding to the vertical Arrow s V is indicated.
  • the pivoting adjustment of the screen elements 36 by one joint 37 can be seen.
  • FIG. 5 is a side view of the crusher 12 at shown removed housing, the breaking waves 20 by the sieve element in front of it in this view 36 are covered. Those on the are clearly visible Circumferential surface of the arranged above the sieve element 36 Metering shaft 32 along a helical line attached driver, which as from this view also emerges, chip-like, that is, with about triangular cross-section, formed and with their Narrow sides transverse to the longitudinal axis of the metering shaft 32 are aligned.
  • the foot width is each Driver about 40% of the diameter of the metering shaft 32 and the sheet thickness about 15 to 25% of the foot width while the height of the driver 33, that is, their radial Extension starting from the circumferential surface of the metering shaft 32, about 60% of the diameter of the metering shaft.
  • Fig. 7 shows a cross section through a second embodiment a breaking wave 22 according to the invention, the T-shaped break or blow bars 27 in place of has rectangular break bars or blow bars 26.
  • the other features are the same as for the first Embodiment match, so that here too the same Reference numbers are used.
  • Pre-broken wood is first put into the machine, that is, into the feed hopper 30 of the crusher 12.
  • the metering shaft 32 conveys the crushed material Direction of the breaking waves 20, 22 and thus ensures a uniform filling of the feed space 30.
  • Above the metering shaft 32 forms a pile of wood, which prevents the broken material from being thrown upwards becomes. At the same time, it acts as dust protection, by having a mechanical filter-like lock for the small parts created during crushing.

  • the distance of the breaking waves 20, 22 from each other and hence the distance of the outer circumference of these breaking waves 20, 22 is chosen so that the radius of everyone provided with the breaking or blow bars 26, 27 Crushing wave 20, 22 that of the adjacent crushing wave 20, 22 penetrates or at a distance from this runs. Which distance is chosen depends largely of the desired degree of comminution of the comminuting material 34.
  • a metering shaft 32 is located above the breaking shafts 20, 22 arranged in terms of their diameter to the Opening of the feed hopper 30 is adjusted. This dosing shaft 32 has drivers that the material 34th into the crushing gap 23 between the crushing shafts 20, 22 promotes. If the metering shaft 32 is switched off, then the crushing waves 20, 22 are also no longer material 34 fed for shredding.
  • the metering shaft 32 are not shown Sensors arranged that the fill level of the Monitor crushing material 34 in the hopper 30. For example, the power consumption of the drive increases on, then the metering shaft 32 is switched off or driven more slowly so that the material accumulation are processed via the breaking waves 20, 22 can.
  • the crushing or blow bars used for crushing 26, 27 preferably have a flat cross section. However, it is also conceivable that the crushing or Form blow bars 26, 27 concave. In any case it must be ensured that two breaking edges per breaking or Blow bars 26, 27 are present.

  • the roll diameter including the break or blow bars 26, 27 is about 400 millimeters and comes with a rotational speed of 500 revolutions per Minute driven.
  • This shredding device will have a breaking capacity of 51 cubic meters per Hour for a final product with an edge length of 40 mm reached. Materials are the starting point with edge lengths of up to 500 millimeters.
  • the distance between the breaking edges of the breaking or blow bars 26, 27 is 30 mm.
  • the advantage of the shredding device according to the invention relies on less wear, one high throughput, due to the high number of breaking edges, a little warming and associated with it a low noise and dust development in comparison with conventional shredding equipment.
  • Another advantage of the invention is that it is small Dust development. This is about 3 percent, whereas the dust development in the prior art, for example with hammer mills, significantly more, namely 14 to 18 percent. Then dust spoken if the grain size is less than three millimeters is.
