Abstract
A specific gravity-specific waste air sorter separates impurities using a vortex for sorting waste into high-specific gravity materials, low-specific gravity materials, and impurities when the impurities are shaken off and removed by means of the hitting of a rotating drum and vanes while the waste fed therein is turned over by a vortex. A main drum has radial vanes, an upper auxiliary drum, and a lower auxiliary drum. The main drum is provided at one side of an input hole, the upper auxiliary drum is provided at the other side of the input hole, and the lower auxiliary drum is provided below the upper auxiliary drum. The main drum and the lower auxiliary drum rotate in the same direction, whereas the upper auxiliary drum rotates in the opposite direction. A vortex is formed between the main drum, the upper auxiliary drum, and the lower auxiliary drum.
