Abstract
A rotary feeder for dosing bulk material, includes a casing having an inner chamber and formed with a top inlet, a bottom outlet and spaced-apart bearing covers flanking the inlet and the outlet. A rotor is accommodated in the chamber and is mounted on a shaft for rotation about a pivot axis. The shaft supports a plurality of vanes extending radially outward from the shaft between lateral end disks, with the shaft being supported on opposite sides of the rotor by bearings. In order to minimize the length of the shaft and a flexure of the shaft when encountering a substantial pressure differential between the inlet and the outlet, the chamber of the housing is sealed from the ambient environment by at least one shaft seal situated axially outwardly from the one bearing of the first and second bearings which is located on a same side of the rotor as the shaft seal.
