Abstract: To provide an apparatus for reclaiming foundry sand and a method for reclaiming foundry sand that can effectively remove binders and so on that attach to returned foundry sand that has been used. Foundry sand that has been used is supplied from a chute for feeding sand 14A to a rotor 16. The rotor 16 is rotated by a driver 20 so that frictional force is generated on the sand in the rotor 16. Then, the sand in the rotor 16 is dropped into the container for washing with water 30 that is located below the rotor 16. In the container for washing with water 30, an agitator 34 is rotated by the driver 20 so that the sand in the container for washing with water 30 is agitated and washed with water.
