ABSTRACT:
A system for the thermal processing of material in a housing having an inlet for receipt of the materials and an outlet for the discharge of the material after thermal treatment. The heating of the materials is accomplished, at least in part, by contact of the materials with a particulate medium which has been preheated in a separate heating operation employing infrared radiant heaters. The housing includes a heating zone separate from the zone used for thermal processing of the materials with the separate heating zone including the infrared radiant heaters. The particulate medium is introduced to the heating zone and brought to a controlled temperature. The medium is then conveyed to the processing zone where it is admixed with the materials being thermally processed. A shrouded zone is located intermediate the processing and particulate medium heating zones. This zone comprises a section of reduced clearance thereby providing a gas and dust lock between the processing and heating zones. The conveyor system may comprise a single shaft supporting agitating and conveying paddles in the processing and heating zones and a screw conveyor in the intermediate shrouded zone.
