  • the control of a crushing machine, in which the perforated disc is installed is designed so that it is not operable when the actual values deviate from the desired values.
  • the Perforated disk serve as a security device, because it can be determined by the target-actual comparison, for example, if a perforated disc is inserted in the flow direction behind the last knife whose bore diameter is so small or whose thickness is so great that can be ruled out that the operator is injured by the rotating knife.
  • the perforated disc has holes whose diameter is ⁇ 6 mm and preferably a thickness ⁇ 5 mm.
  • data are stored on the means which in particular have information about the size of the bore and preferably about the thickness of the respective perforated disk.
  • data can additionally be stored on the means, which relate to the transit time and the load of the perforated disc.
  • the wear of the perforated disc can be automatically determined, so that when a certain degree of wear of the perforated disc is exceeded, the crushing machine is no longer in operation, because the perforated disc according to the invention is no longer sufficient as a security device.
  • the means on which data can be stored and retrieved provided in a closed cavity in the perforated disc, so that it can neither be found by unauthorized persons, nor manipulated.
  • the arrangement of the agent should be made in any case so that it, if it is accidentally discovered, unusable in the expansion, preferably destroyed.
  • the data query from the built-in such a perforated disk data storage succeeds in a crushing machine best when the means is biretemental wirelessly coupled to a arranged on the crushing machine or mobile transmitting and receiving system, via an amplifier to the second data storage and / or electronic Machine control can be connected so that the data of the agent can be read and changed.
  • the transmitting and receiving system is provided with particular advantage in the immediate vicinity of the perforated disc.
  • the data memory integrated in the perforated disk according to the invention after appropriate data removal, transmission, processing and reproduction on a corresponding display, the data suitable for the identification of the perforated disc and possibly also the data of an associated counterpart, for example a knife, so the whole used for comminution system.
  • the data can be recognized by the controller of the crushing machine and taken into account in that the operation of the crushing machine is allowed only when functional parts are in use.
  • the means is a sensor chip on which data can be reversibly stored and retrieved.
  • the present invention has the advantage that only clearly identifiable components are used in the cutting set, so that on the one hand a trouble-free operation of the crushing machine is ensured and on the other a perforated disc can be used as a backup device of a cutting set, because the crusher only then put into operation can be, if a very specific perforated disc has been identified with a not-too-large amount of wear from the crusher.
