摘要： An apparatus to remove adhering material from the surfaces of sand to recycle the sand is disclosed. The apparatus includes a container (13) to hold sand (S) to be processed, the container having a bottom opening; pressing means (17-20) to press the sand in the container downwards; a rotor (10) disposed under the bottom opening of the container (13), the rotor (10) having a surface (11) that contacts the sand in the container; means (2) for driving the rotor (10); and a gap (G) disposed near a place between the container and the rotor. The sand contacts and is abraded by the rotary surface (11 ) of the rotor (10), and the processed sand is discharged by the centrifugal force of the rotor (10) from the gap (G) onto a chute (21).

摘要： A device for removing foreign material from sand is disclosed. The device includes a rotary box which is driven such that sand is centrifuged therein. The box includes a circular bottom plate, a circumferential and inclined wall extending from the circular end of the bottom place, upwardly and outwardly, and ring portion which extends inwardly from the top of the inclined wall. A plurality of rollers are disposed in the box, each roller having a movable surface substantially parallel to and spaced apart from the circumferential and inclined wall of the box. Sand in the rotary box is centrifuged and circumferentially deposited on the inclined wall to form a sand layer which becomes progressively thicker and then contact the movable surface, subjecting the sand to shearing and compressive forces. Processed sand then overflows from the ring portion of the rotary box.
