ABSTRACT: METHOD AND APPARATUS FOR RECLAIMING FOUNDRY SAND. A method and apparatus for reclaiming used foundry sands including organic resin-bonded sands and clay-bonded sands is shown. The method includes passing used sand downward through a series of vertical, fluid sand beds. Hot air is forced upward in countercurrent fashion through the beds in turn so that a boiling ac- tion is achieved in the sand masses. The combination of thermal and abrasive action removes both organic resin and clay-bonded materials from the sand in one continu- ous operation.
