Abstract
In order to effectively remove and reclaim sand from a metal casting, an apparatus and system includes a bed having an entrance for receiving the casting and an exit for removing the casting. The bed is adapted to fluidize sand and may also be subjected to vibratory forces. The apparatus and system further includes a sand distribution conveyor for supplying sand to be fluidized to the bed at a point generally near the entrance and a sand transfer conveyor for removing sand to be recirculated from the bed at a point generally near the exit. The bed achieves a thorough mixing of the sand due to the fluidization and vibratory forces. With these features of construction, the apparatus and system also includes a sand return conveyor with all of the conveyors being vibratory and insulated to achieve energy efficient sand recirculation.
