Abstract

A discharging apparatus for a large diameter, generally vertically walled reaction vessel in which a recessed dish or receiving structure having the same diameter as the reaction vessel is mounted beneath the lower discharge end of the reaction vessel. There is an aperture in the floor of this receiving structure and a rotating impeller urges material received from the reaction vessel through this aperture into a smaller diameter recessed receiving structure which is also equipped with a rotating impeller to remove material to a screw conveyor for removal from the system. This screw conveyor can be significantly smaller than would be required using a conventional screw conveyor reaction vessel discharge.
