Reclamation sand is the process by which foundry sand is reconditioned without significantly affecting its physical properties. During the sand reclamation process, binders and coatings that adhere to sand grains during casting production are removed to recycle sand for subsequent use. The two primary purposes of sand reclamation are cleaning the mold material grain to remove binders that still adhere to it following the thermal load or are firmly affixed to the grain due to this load and the removal of powdered components i.e., separation of the reclaimed molding base material. The actual reclamation consists of a peeling or impact process which removes all adhesions from the sand grain to the best possible extent. For this purpose, the used mono or mixed sand is prepared in various process combinations. Following the reclamation process, the sand grain is separated.
