    • 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).

    • 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.
    • 提供了用于从砂表面去除粘附材料的装置。 该装置包括旋转箱(5),用于旋转旋转箱的驱动装置(20)和具有可移动表面(15)的可移动装置(8)。 旋转箱包括圆形底板(5A),周向倾斜壁(5B)和环形部分(5C)。 可移动表面(15)基本上与旋转箱的倾斜壁(5B)平行并间隔开。 当沙子被旋转箱离心时,沿倾斜壁形成砂层S. 其厚度大于可移动表面(15)和倾斜壁(5B)之间的距离的砂层与旋转箱一起移动并进入到表面(15)和壁(5B)之间,从而赋予 对砂的压缩和剪切力有效去除粘附材料。 经处理的砂然后使旋转箱的环部分(5C)溢出。
