されて、上述の作動が繰り返される。Next, the operation of this embodiment will be described. A crushed resin 22 is put into the hopper 10 from a crusher (not shown). The thrown resin pulverized material 22 drops from the lower part of the hopper 10 onto the conveyor belt 2, and the thickness adjusting plate 3
1 and the conveyor belt 2 have a thickness of a gap 35 and are adsorbed to the conveyor belt 2 in layers. When the resin pulverized product 22 is a petroleum-based plastic, it tends to be negatively charged, so it is negatively charged during molding and pulverization, and the resin pulverized product 22 is adsorbed by the charging device 30 to the conveyor belt 2 which is positively charged. . Then, in this state, the conveyor belt 2 moves in the counterclockwise direction indicated by the arrow 26 as the drive roller 1 rotates. With the movement of the conveyor belt 2, the resin pulverized material 22 has a space 1 between it and the conveyor belt 2.
2 is transferred to a classifying member 6 in which the resin 2 is arbitrarily adjusted, and the resin pulverized material 22 larger than the interval 12 is separated from the conveyor belt 2 by the classifying member 6 and falls into the collection box 7. On the other hand, the crushed resin material 22 smaller than the interval 12 moves to the static eliminator 8 while being adsorbed. Since the conveyor belt 2 is destaticized by the destaticizing device 8, the crushed resin material 22 falls into the recovery box 9. Then, the conveyor belt 2 from which the crushed resin material 22 has been removed is again moved to the charging device 30 to be positively charged, and the above operation is repeated.

る。In this embodiment as described above, the crushed resin material that has been electrostatically adsorbed is classified by the distance between the classifying member 6 and the conveyor belt 2. Since this distance is easy, the size of the crushed resin material is classified. Can be changed arbitrarily. Also,
By removing the static electricity, the fine resin pulverized product can be removed from the conveyor belt 2, so that reliable removal is also possible.
