ABSTRACT:
A partition (51, 52, 53) is provided within a vessel (1) for dividing the vessel into two along the vertical direction of the vessel except upper and lower portions thereof. The vessel (1) contains polishing particles (4). A cleaning liquid sprayer (8) is provided in the upper portion of the vessel (1). A discharge opening (2, 3) is provided in a lower portion of the vessel (1) for discharging the cleaning liquid passing through the perforated plate (2). Vibrators (71, 72) are mounted on the brackets (61, 62) to the wall of the vessel (1) for vibrating the vessel so as to generate convection currents of the polishing particles (4) in such a manner that polishing particles flow downward on one side of the partition (51, 52, 53) and upward on the other side thereof.
