摘要： A device for removing adhering material from sand surfaces is provided. The device includes a rotary box (5), driving means (20) for rotating the rotary box, and movable means (8) having a movable surface (15). The rotary box includes a circular bottom plate (5A), a circumferential, inclined wall (5B), and a ring portion (5C). The movable surface (15) is substantially parallel to and spaced apart from the inclined wall (5B) of the rotary box. As the sand is centrifuged by the rotary box, a sand layer S is formed along the inclined wall. The sand layer, the thickness of which is greater than distance between the movable surface (15) and the inclined wall (5B), moves around with the rotary box and come between the surface (15) and the wall (5B) to thereby impart to the sand compressive and shearing forces to effectively remove the adhering material. The processed sand then overflows the ring portion (5C) of the rotary box.
