  • the crushing devices with relatively small teeth have a worse intake behavior, as the crushing devices with the relatively large-sized teeth.
  • Inadequate comminution of the material or frequent clogging of the comminution device with the relatively small-sized teeth is the result.

Rather, the expert has previously assumed that due to the use of small-sized cutting tools, of course, an inadequate intake behavior is expected, which is why several devices for comminuting the material with different tooth sizes has been used in successive crushing steps for the production and screening of the screenings in order to avoid that frequent clogging or sticking of the devices may occur due to the insufficient feed behavior.
