  • the height-adjustable in the base body rotor is made of wear-resistant steel and has at its ends releasably received baffle elements, which crush the introduced components by the resulting impact impact stress in different sized fragments, which can then be separated from each other.
  • the cited document gives no indication that the comminuted particles are deposited in several fractions with different particle sizes by means of downstream sieves arranged one above the other, which are directly downstream of the ejection opening of the impact reactor.
  • a baffle device for crushing wood is made WO2004024331 known.
  • a device for comminuting material in particular of wood, comprises a baffle reactor which has a substantially cylindrical basic body in whose closed interior a rotor driven by a motor rotates with at least one baffle element which contacts the material and produces a crushed high momentum transfer into partial components.
  • the device further comprises an ejection box which is connected to the interior of the cylindrical base body via an ejection opening, and a first auger arranged in the ejection box below the ejection opening for conveying the comminuted material from the ejection box.
  • the device according to the invention is characterized in that below the ejection opening a first sieve with a first mesh width is arranged which, viewed from the ejection opening, extends inclined towards the first auger relative to the horizontal, and that below the first sieve one relative to the horizontal inclined sliding surface or a relative to the horizontal inclined second sieve is arranged, which has a relation to the first mesh size reduced second mesh size.
  • the sliding surface, or the second sieve, extending from the cylindrical base body to a second screw conveyor, which is arranged below the first screw conveyor.
  • the ejection box of the device according to the invention can be kept comparatively compact in terms of its dimensions, since the required footprint for the sieves - which is determined by the vertical projection of the sieves - by the inclined arrangement of the same against their effectively reduced effective screen area.
  • the particles remaining on this remaining particles which do not pass downwards through the sieve meshes, slip downwards in the direction of the feed screw due to their own weight and thereby the sieve surface in the region of the ejection opening for the following to release the particle mixture emerging from the ejection opening.

  • the ejection opening can be closed by a flap or a slide, whereby the possibility of a discontinuous transfer of the comminuted material from the baffle space into the ejection box is created in an advantageous manner.
  • This alternative embodiment has the advantage that the supply amount of crushed material controlled in the ejection box to regulate, if desired, the amount of shredded material on the first and / or second screen. As a result, it is possible in particular to effectively prevent overflowing or overshooting of the sieves and clogging of the conveying screws.
  • the additional advantage that the removal of the crushed material from the baffle out can be made controlled by other parameters, for example, based on the located in the crushed particles, or in the baffle moisture, which to avoid a lump formation and an associated clogging of the sieves must not be too high.

  • the use of a snail trough equipped with sieve openings has the advantage that particles with a smaller diameter in relation to the mesh size of a sieve, which inadvertently get into the worm trough associated with the sieve in question, still pass through the sieve openings in the worm trough below lying sieve or fall into the underlying screw trough and thereby be applied according to their size in the correct sieve fraction. This is additionally promoted by the rotating conveying movement of the screws in the screw trough and the resulting mixing and circulation of the particles in the screw trough.
  • the third sieve has a mesh size in the range of 20 mm, the first sieve a mesh width in the range of 15 mm and the second sieve a mesh width in the range of 5 mm.
  • the wood particles must be present in different sizes to a particle board on the one hand the smoothest possible surface and on the other hand a high To give resilience.

  • the amount of particles above the desired area can also be reduced because, on the one hand, the particles stay longer in the baffle space to be sufficiently crushed and, on the other hand, through a narrower range between the mesh sizes of the first and third screen, the proportion of too large particles in the particle mixture is reduced, which passes through the third sieve.
  • horizontally extending barrier strips can be arranged on the first screen, which reduce the speed of the comminuted material emerging from the ejection opening as it moves along the inclined screen.

  • a high ejection speed of the particles passing through the ejection opening onto the first screen e.g. may be required for the separation of mixtures by a corresponding peripheral speed of the rotor, can be compensated by an appropriate choice of the inclination of the sieve plate of the first sieve.
  • the first auger is in this case located below the discharge opening in the region near the outer wall of the impact reactor, and the second sieve is located in the same direction of inclination or the opposite direction of inclination in the manner previously described below the first sieve.
