S52 series centrifugal sand reclamation equipment adopts dry centrifugal reclamation principle,is mainly used for used resin coated sand reclamation. When working,the used sands will be throwed into the wear-resisting lining ring under the action of high-speed rotating impeller. By the mutual collision and friction between sand and lining ring, impeller and machine box, sands and sands, the inert membrane at the surface of the resin will be removed. According to the different technological requirements of used sand, This machine can be adjusted the reclamation cycle index to get  the technological requirements of reclaimed sand.
