Next, sieve hole 5b (sieve auxiliary hole 51
The larger waste on the sieve that did not pass b ')
Due to the vibration of the porous member 5, the air outlet 3 is further discharged on the wind selecting portion 5c.
Air having a small specific gravity and a small weight is floated upwardly away from the metals by the air that is conveyed to the side and blows out from the wind selecting hole 5f on the wind selecting portion 5c. Then, the floated lightweight waste, that is, the lightweight plastics and papers, is sucked into the suction hood 25 through the suction port 26 together with air by the blower 31, and is collected by the collector 30 via the conduit 29. . Relatively heavy waste that does not surface, mainly wood chips,
The mixed metal and rubber pieces are separated by the control weir 5h, and the wind selector 5c
Suspended above. Then, the suspended wood chips and the like get over the control weir 5h and are sent to the discharge trough 37 through the discharge port 3. In the waste on the discharge trough 37, first, the magnetic metal in the waste trough is collected by the metal collecting magnetic separator 38, and at the end of the discharge trough 37, aluminum is collected by the aluminum collecting separator 39.
Are blown away and collected, and the remaining ones become combustibles.

いという事態はほとんど起きない。During this sorting operation, one end is a suction hood.
It is pulled by 25 suction and the other end is a magnetic separator for metal recovery.
Long objects such as tapes that tend to balance and remain on the discharge trough 37 by being entangled with the metal object adsorbed on the 38 and being sent together on the discharge trough 37 through the discharge port 3 and discharged. , The cutters 43 and 44 as shown by the chain lines in FIGS.
It is cut by being caught by the saw-tooth blades 43a, 44a, and one end side is discharged to the suction hood 25, and the other end side is discharged through the magnetic separator 38 which rotates together with the metal object. Therefore,
Unlike the conventional case, the long object does not remain on the discharge trough 37, and the smooth transportation due to the vibration of the waste can be continued without interruption. When the long objects are cut by the cutters 43 and 44, the cutter itself vibrates together with the main body 4 in addition to the abutting force of the long objects which is entangled with the metal object and caught by the sawtooth blades 43a and 44a under the action of this force. As a result, the situation in which disconnection is not possible rarely occurs.
