ABSTRACT:
The milling apparatus (1) has a bucket with a receiving chamber and has a milling unit with a milling rotor (14). The receiving chamber has a receiving opening (4) and is embodied as a bucket (2). On the bottom of the bucket (2), a through opening (19) is provided, which leads into a milling chamber (12). The milling rotor (14) can move material both into the receiving chamber and out of it again. To achieve both modes of operation, in a first embodiment a drive mechanism rotating in a predetermined direction (D) is provided; a beating arm (16) is associated with the first mode of operation, and a further beating arm (24) is associated with the second mode of operation. In another embodiment, which makes do with a single beating arm (16), the milling unit (54) can be operated in two different working positions via a turner. The positions differ from one another by a 180° rotation about a vertical axis that is perpendicular to the axis of rotation of the milling rotor (14).
