In most sand foundries, the majority of sand is removed during a shakeout operation. This aids the cooling process and minimizes the amount of sand to be removed later by the blast cleaning operation. In a low percentage of requirements, sand removal is accomplished solely by the blast machine with no previous shakeout operation.
