PURPOSE: To provide a selection device of waste product which enables an incidence of plugging to be reduced significantly, minimizes the size of an air generation source, and need not be enlarged structurally. CONSTITUTION: A sieve part 5a with many sieve holes 5b is formed of almost half the supply port side of a porous member 5 provided almost horizontally on a main box-type hollow system 4 which can vibrate, and a stepped air selection part 5c with a single step formed by an upright wall 51 with air selection holes 5f is formed of almost half the discharge port side. In addition, a magnetic selection part 17 is provided below the sieve part of the porous member, with a metal piece discharge port 17c provided. Further, a sectioned chamber 15 for the air selection part is formed of an area below the air selection part for the porous member, with air supply ports 16a, 16b provided. Besides, a concurrently air power using-type sieve part 18 is provided at a position below a sectioned chamber for the air selection part and adjacent to the magnetic selection part, with a discharge port 18c for a material over the sieve provided. A sectioned chamber 19 for a concurrently air power using sieve part is formed of an area below the concurrently air power using-type sieve part, with a discharge port 19b for a material below the sieve and an air supply port 19a provided. A suction hood 20 is provided above the concurrently air power using-type sieve part. |
