  • centrifuges that serve both the de-oiling and the cleaning of such mass parts. It is provided that the mass parts are de-oiled in a centrifuge in a first step.
  • the de-oiling is based here on the principle of centrifugal force, that is to say that the oil components adhering to the mass parts are centrifugally discharged from the centrifuge due to the high rotational speed of the centrifuges, which for this purpose has a centrifuge casing with a multiplicity of openings through which the oil particles escape from the centrifuge Centrifuge can escape. The thus ejected oil particles are then deposited on a wall of a bell surrounding the centrifuge, from where the oil particles are collected and removed.
  • the mass parts After the mass parts have been de-oiled, the mass parts are fed into another centrifuge, in which the mass parts are cleaned. For this purpose, a washing of the mass parts is provided with a washing fluid, which is also separated at the end of the washing process by centrifugal forces from the mass parts. Once the mass parts have reached a predetermined degree of drying, the mass parts are rinsed in another centrifuge, that is freed from still adhering washing fluid. Again, centrifugal forces are used to remove the flushing fluid with the captured particles of the washing fluid before the mass parts are then subjected to a drying process, with hot air generally being introduced for this drying process.

  • This drum thus represents the above-described centrifuge.

  • the mass parts are filled only once in the centrifuge, so that a transfer from one basket to another or from one centrifuge to another is not required. Furthermore, the treatment steps can be carried out separately but always in the same centrifuge, since this allows both the de-oiling and the cleaning of the mass parts. The mass parts once added for deoiling in the first station remain in the same centrifuge until final cleaning and drying. As a result, damage to the mass parts are avoided by decanting.

  • the centrifuge is moved from the first position to a second position within the support frame. In this second position, the centrifuge contains the de-oiled mass parts. In this second position, a washing fluid is then introduced into the centrifuge, with which the mass parts are washed. This process can be performed with a reduced number of revolutions of the centrifuge compared to the first step. It is also possible that the centrifuge is switched alternately in opposite directions of movement, or that the centrifuge is slightly tilted about a horizontal axis, so that a movement of the mass parts with each other is possible. As a result, areas are cleaned, which are not accessible by contact between the mass parts with constantly arranged in the same orientation mass parts.
