A pair of the mesh rollers have metal meshes on the surfaces thereof and are rotated while holding the shredder dust 101. The foreign matter 103 is adhered to the metal meshes and the plastic pieces 102 fall without adhering to the metal meshes. A plastic recovery box 131 collects the plastic pieces 102 falling from the gap between the mesh rollers. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
