Rotor box for a ground milling machine and ground milling machine having such a rotor box

The present invention relates to a rotor box for a ground and/or road milling machine such as, in particular, for a road miller or a trench cutter which surrounds at least one milling rotor for removing ground material (B). It is provided that the wall of this rotor box is configured at least in one section with an enlarged distance from the milling rotor in order to allow a specific guiding of the milled material away from the milling rotor in this region of the rotor box and that at least one separating device is disposed between this section of the wall and the milling rotor, which prevents contact of the guided-away milled material with the milling rotor in this region. The present invention further relates to a ground and/or road milling machine such as in particular a road miller or trench cutter having at least one such rotor box.
