Abstract
Apparatus for reclaiming sand is provided for removing impurities therefrom. The apparatus includes a vibratory conveyor in which the sand is fluidized and heated. The conveyor vibrates the sand to obtain a more uniform temperature. The apparatus may be used to clean used process sand, such as by pyrolyzing binder from foundry sand, or may be used to remove impurities from virgin sand, thereby minimizing the amount of silica which must be added to the virgin sand.
