  • the screen frame is further pushed in the insertion direction, so that also takes place a seal against a front abutment ⁇ surface / wall of a receiving space for the sieves. ⁇ same time, the edge of the screen frame is sealed by the stopper face.
  • the eccentric 6 When the screen frame has to be removed, the eccentric 6 is rotated counterclockwise, after which movement of the rail 3 is generated downwards.
  • the movement of the rail 3 allows removal of the screen frame also in cases where dirt deposits cause a clamping of the screen frame.
  • the rail 3 also has a locking lug 8, which protrudes with the rail 3 in the lower position U from a receiving space and prevents the closing of a cover of the receiving space. If the rail 3 is not in the lower position ⁇ on U, the cover can be closed. It is thus prevented that the bulk material screening device is put into operation without sieves or with incorrectly positioned sieves.
