Abstract
Inefficiencies in reclaiming foundry sand from foundry cores made up of sand and an organic resin binder are reduced in a method of reclaiming such sand that includes the steps of reducing a foundry core made up of sand and an organic resin binder to small clumps or individual particles, placing the small clumps or individual particles in a bed and introducing a heated gaseous oxidant into the bed generally from the bottom thereof in sufficient volume to fluidize the bed and at sufficient temperature to oxidize the resin binder on the small clumps or individual particles. Also disclosed is an apparatus for performing the method.
