Abstract
A dual sand reclaimer comprising a drum formed of an inner and outer cylinder, substantially along its length, the drum being formed into three segments, an entrance segment wherein the castings are initially deposited for removal of its green mold sand, the inner cylinder thereat being perforated to provide for separation of the sand from its castings, a middle segment wherein the castings and internally arranged mold sand are subjected to abrasive members that remove any core sand, and a third or discharge segment from which the castings exit, and having an inner cylinder thereat perforated to provide for the passage of the core sand and abrasive members therethrough, with the sand being screened for removal thereat, while the abrasive members are returned by vanes arranged intermediate the inner and outer cylinders of the middle segment of the drum for a return to the leading end of the segment for reusage.
