ABSTRACT:
A thickener has a receptacle in which a thickening drum having an axial filtering wall is mounted in a receptacle for rotation about an axis. A liquid-and-solid-materials mass to be thickened is introduced into the one axial end of the thickening drum. Thereby the solid materials contained in the mass to be filtered form a filtering layer on the inner surface of the a filtering wall and liquid filtrate from the mass flows through the filtering layer and wall into the receptacle. At least one barrier plate radially divides the inner space of the thickening drum into axially sequential spaces, the barrier plate being fixed within the thickening drum for rotation therewith. The barrier plate is provided with at least one opening axially therethrough for flow of the mass to be thickened and at least one opening axially therethrough for air flow in the axial direction of the thickening drum. The thickened mass is then discharged from the other axial end of the thickening drum.
