  • both the crushing tools and the counter-blade device have a tooth structure
  • the teeth, in particular the tooth flanks do not wear symmetrically, so that the gap dimension can not be reduced uniformly by displacing the counter-blade device in the direction of the rotor over the entire tooth structure.
  • the tools or the counter knife must be replaced to again to provide the necessary small gap, with which such good can be crushed. The replacement of these shredders limited to a considerable extent the availability of the device.

  • the two counter blade strips can be conveniently attached to a common counter blade traverse, which may extend parallel to the rotor axis. It is understood that several, for example two or three such counter-blade devices can be arranged over the surface of revolution of the comminution shaft.
  • the displacement of the counter-knife strips can also take place in a direction which has both a component in the radial direction and a component in the circumferential direction. Such a displacement is particularly advantageous in cases in which a clearance angle between the crushing tools on the rotor and the counter knives is set.
