PROBLEM TO BE SOLVED: To prevent the occurrence of concentrated collision with the given part of a separation rail when a mixture consisting of contaminants, an abrasive, and a game ball is moved from a fixed part on the inflow side to a separation rail by a method wherein the separation rail is arranged movably to the fixed part on the inflow side and a fixed part on the outflow side. SOLUTION: The ends on one side of a plurality of separation rails 4 are rotatably supported below the front of a fixed part 2 on the inflow side by a bush 8, and an interlocking rotation mechanism 9 is arranged at the part, protruding to the opposite side to the bush 8, of the separation rail 4. The part, protruding to the opposite side from the interlocking rotary mechanism 9, of one of the separation rails 4 is coupled to the output shaft of a motor 10 mounted on the fixed part 2 on the inflow side. The other ends of the separation rails 4 are rotatably supported at the front part of the fixed part 3 on the outflow side by a bush 12. Since a plurality of the separation rains 4 are rotated in the same direction through an interlocking rotary mechanism 9 by drive of the motor 10, when a mixture after polishing consisting of contaminants, an abrasive, and a game ball 5 is moved from a fixed part 2 on the inflow side to the separation rail 4, the mixture is prevented from concentrated collision with the given part of the separation rail 4. |
