  • Patent number: 3976422
    Abstract: An apparatus for reclamation of resinous moulding mixes used in foundry practice incorporates three chambers contained in a common housing, namely a heating chamber (3), a firing chamber (2) and a cooling chamber (4). A bottom (6) of the heating chamber forms a fluidizing conveyor conveying the moulding mix from a chute (8) to a closure (27) through which the mix drops onto a grate (5) of the firing chamber (2). The fuel is supplied through a system of collectors and nozzles to the clearances between the grate elements, while the air for fluidizing of the mix is supplied through a duct (14) to the space below the grate. The firing chamber is connected with the cooling chamber by means of the mix transfer holes (10) and (11). A bottom (12) of the cooling chamber forms a fluidizing conveyor conveying the mix to a discharge hole (24). The cooling chamber includes a cooler (23).
