    a) a controller (4) that is connected to a first measurement transmitter (4.1) for detecting the motor output (N) and with a fourth measurement transmitter (4.4) for detecting the height (h) of the waste stream (3) supplied to the reduction machine (2) for controlling/regulating the supply device (1), said supply device comprising a feed belt (1.1) and a forced supply (1.2) and by at least one connection with the supply device (1) for regulating the speed of the supply device (1).
    b) at least one measuring element (4.5) corresponding to the housing (2.1) or its parts and the controller (4) connected thereto for ejecting coarse, heavy or hard parts.
  8. The plant according to claim 7, characterized by at least one adjustment element (2.1.2) disposed in the housing (2.1) for changing the interior geometry of the housing (2.1).
  9. The plant according to any one of the claims 7 or 8, characterized in that the controller (4) is connected to one second measurement transmitter (4.2) for detecting the motor temperature (T1) and/or to a third measurement transmitter (4.3) for detecting the temperature (T2) of the motor bearings.
  10. The plant according to any one of the claims 7 through 9, characterized in that at least one measuring element (4.5) is a vibration sensor (4.6) connected to the controller (4), said controller (4) being connected to a drive element (2.1.1.1) for controlling the ejection flap (2.1.1) on the housing (2.1).
  11. The plant according to any one of the claims 7 through 9, characterized in that at least one measuring element (4.5) is a pressure sensor (4.7) connected to the controller (4), said controller (4) being connected to the drive element (2.1.1.1) for controlling the ejection flap (2.1.1).
  12. The plant according to any one of the claims 7 through 11, characterized in that the adjustment element (2.1.2) for changing the interior geometry in the housing (2.1) is a component part that cants off a dead corner space (2.1.3) above the ejection flap (2.1.1) toward the upper cover of the housing (2.1).
  13. The plant according to any one of the claims 7 through 12, characterized in that the ejection flap (2.1.1) abuts at least one element that has not been illustrated like a breaking bolt having a line of weakness, said line of weakness being dimensioned such that coarse, heavy or hard parts are allowed to pass outside through the ejection flap (2.1.1) by virtue of pressure build-up.
