FIELD: metallurgy, particular, methods for portion reclamation of molding sand, mainly, clay-bound used molding sand for its repeated use. SUBSTANCE: dust particles are pneumatically sucked out during treatment to reduce portion mass which is compensated in mass correspondingly by volume due to adding of definite amount of sand. EFFECT: provision of constant removal of sand particle shells in the entire course of portion treatment.
