Resin bonded sand equipment uses physical, chemical, mechanical or heating methods to remove the residual adhesive film wrapped on the sand surface, so that the sand can be roughly restored to the original sand state before adding the adhesive, so that the old sand can be recycled. The resin sand production line is one of the commonly used equipment in the foundry industry. The castings produced by the resin sand production line have high dimensional accuracy and surface quality, good fluidity of resin sand, and can improve the filling of mold. The sand has good thermal stability, less thermal expansion, stable chemical performance, decreased acid consumption value, and simple control of resin sand performance, which is conducive to improving casting quality, reducing defects such as ripple and mechanical sand sticking, so as to improve quality and labor productivity and reduce labor intensity of workers. After the resin sand production line is recycled, the old sand can save the sand cost, reduce the sand cost of enterprises, reduce the pollution of new sand to the environment, and make more than 90% of the waste sand can be reused.
