【Abstract】 A new mechanic reclaiming system for used sand has been developed, and its application on steel castings process with sodium silicate sand was introduced. The properties of the reclaimed sand were investigated in contrast to the new sand. The results showed that the reclaimed sand has more round shape than the new sand. After application of this new technology to the casting process, the results showed that this technology is effective, and it can solve the environmental pollution problems produced by the traditional reclaiming technology.更多还原
