ABSTRACT:
An apparatus for feeding bulk material includes a housing which accommodates a rotor arranged between an inlet port and an outlet port of the housing and having a plurality of radially extending vanes. The vanes are fixed on a shaft and provided with sealing strips for sealing the vanes against the housing. For compensating occurring wear and maintaining the sealing action, the sealing strips are corrected by an adjusting bar with two spaced conical sufaces which cooperate with push rods having one end lying against the conical surfaces and another end in force-locking connection with the sealing strips.
