The utility model has the advantages that:

1. the undersize material is subjected to twice deep air separation treatment, so that the undersize material can be treated to reach the standard of reutilization.

2. A small plastic remover is introduced by a negative pressure induced draft device during air separation treatment of undersize materials, so that the soil materials and the small plastics are separated to meet the use requirement.

3. Proper equipment selection, reasonable arrangement, scientific flow and good effect.
