Sand reclamation 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. Thus, the sand must be cleaned to remove the binders that adhere to it during thermally intensive operations.
