  Recently, surface scrubbing mostly reclaims waste sand in foundries. There are 3 types of reclamation methods impact, friction and grindstone. In this study, we tested 7 new types of silica sand by grindstone method to investigate the relation between the material characteristic of silica sand and reclamation. The results showed that silica sand was tended to be more easy-to-grind when the loose bulk specific gravity was high. We also found that the grain shape and true specific gravity of silica sand, but not the latter half affected the first half of reclamation. Correlation was seen between the mold strength, bulk density, SiO<sub>2</sub>, and total clay after reclamation.
