ABSTRACT:
A sealing device for sealing between two relatively rotating cylindrical surfaces in a conveyor has its one cylindrical surface formed as a stationary wall portion in a transition housing and its other cylindrical surface formed as a cylindrical wall portion of a rotating bottom in said transition housing, one of said cylindrical surfaces being provided with at least one scraper and/or impeller blade acting against the other of said cylindrical surfaces in order to feed material, during operation, in a direction into the interior of the conveyor, thereby to reduce the tendency of the bulk goods to penetrate between and cause wear of said two cylindrical surfaces.
