Abstract

A device for treating granular and/or lumpy materials by passing a gaseous medium therethrough characterized by a chamber having at least one material discharge opening at a lower end and a material supply device having at least one member having a circular cross section coacting with a flanged opening of the chamber to form a pair of coaxially extending supply channels with the innermost channel being provided with a hood having a plurality of discharge pipes connected to a separate gas discharge and the outer channel being connected to a separate gas discharge conduit. Preferably, the outer channel is provided with an annular hood which is in communication with the other discharge channel by a plurality of discharge pipes. Either one of the two hoods may be provided with an adjustable member to enable varying the heighth of the hood. The material supply device preferably has a single inlet or feed pipe which is coaxially aligned with an opening in the first member which opening is provided with a conicalshaped closure member to regulate the introduction of material into the inner supply channel.
