ABSTRACT:
A system (10) particularly suited for reclaiming used foundry sand by means of thermal reclamation. The subject system (10) includes, arranged in cooperatively associated series relation, thermal reclaimer means (14), post reclaimer means (15), primary cooling means (16), separator means (18), classifying and dust removal means (19), scrubber means (20) and secondary cooling means (22). The used sand, which preferably is first fed through a lump-crusher, shake-out apparatus (12), is made to pass through thermal reclaimer means (14) while being heated to a predetermined temperature for a preestablished period of time in order to accomplish the burning away of the organic materials, i.e., matter, which are present in the used sand. From the thermal reclaimer means (14), the used sand passes to and through the post reclaimer means (15) for further reclaiming and then to and through the primary cooling means (16) wherein the heated sand is cooled to a suitable temperature. The separator means (18) is operative to effect the removal of tramp metal from the cooled, thermally reclaimed sand. Thereafter, the cooled, thermally reclaimed sand is made to pass through the classifying and dust removal means (19) for classifying and removal of dust and fines and then through the scrubber means (20) wherein the dust associated with the particles of sand is removed therefrom. Finally, the substantially dust-free, cooled, thermally reclaimed sand passes through the secondary cooling means (22) wherein the sand is further cooled to substantially ambient temperature.
