Definitions

  • Blow bars with essentially bar-shaped bar bodies are used, which are adapted to different requirements with regard to the material to be shredded, the shredding performance, only by a certain longitudinal profile u. The like. Adjusted, but this is unsatisfactory, especially for smaller machines with their various uses.
  • the wear when using the blow bars in one position can also be limited to one cutting edge half, which allows full use of the blow bars in the other position.
  • the recesses or interruptions of the cutting edges result in more favorable cutting edge shapes in terms of the impact conditions and gap conditions, since corners or strongly curved roundings occur in the cutting edge course, as a result of which the surface pressures when the cutting edges are impacted on the material to be shredded and thus the shredding effect are increased.
  • the cutting recesses or interruptions can have different shapes, in particular u or v shape, and are expediently combined with a similar longitudinal profile of the last body.
  • the mounting lugs can be a dovetail-shaped or a mushroom-shaped widening
  • the mounting lugs can be a dovetail-shaped or a mushroom-shaped widening
  • wedge-shaped contact surfaces of the mounts together with wedge and clamping drives can provide for a corresponding mounting of the mounting bracket of the blow bars, whereby a longitudinal mounting bracket per blow bar is usually sufficient, but it is also quite possible to use two or more parallel mounting approaches and appropriately trained rotor mounts can give.
  • the rotor 1 takes two diametrically opposite one another Blow bars 7, whereby the cheek parts 4 and the support plates 5, 5a result in a cross-section flattened on both sides between these two blow bars 7 and an approximately elliptical outline shape E is produced. Correct use of the blow bars 7 is ensured, which come into effect with their front side and the cutting edges 9 without being impaired by the rotor cross section. In addition, they are supported by the support plates 5a over the entire length, which makes them highly resilient and stable.
  • an axially parallel locking bar 17 is also provided here, which extends between the support plates 5a of the rotor receptacles 6 and projects through grooves 18 of the mounting lugs 15, which are lined up in series along the plane of symmetry S of the blow bars 14.
  • the blow bars 14 are divided lengthwise into two parts 14a, a common locking bar 17 being provided for locking.
  • blow bar 33 the bar body 33a of which has two parallel mounting lugs 34 and is equipped with axial normal cutting edges 35 and axial cutting edges 36 which intersect in a grid-like manner.
