Casting sand recovery - detaches sand from the casting in two cleaning stages to give separate types bonded only with clay and only with resin

摘要

To regenerate casting sand, when bonded with clay and resin when taken from a mould, the clinging sand is initially detached from the casting as the casting is removed horizontally to remove only the sand containing a clay bonding. When the casting is vertical, or at an angle, the remaining sand containing bonded resin is detached and cleaned off. USE/ADVANTAGE - The two-stage operation removes the sand from the casting, in separate types of sand according to the bonding with clay and with resin, so that the casting sand material can be regenerated and recovered for further use, to reduce disposal vols. and with less loading on the environment.
