Method and apparatus for sorting solids by airstream

摘要

An airstream solid sorting technology easily and efficiently sorts electric wire and other slender objects from other unslender objects in crushed bulk wastes. A mixture of slender and unslender objects is supplied into an airstream sorting vessel, in which a turbulent stream of gas supplied from below through a meshed screen tilted in its bottom agitates the mixture. Slender objects stalling and falling longitudinally in the direction in which gravity works pass through the meshed screen, thus falling into a slender objects collecting vessel placed below the meshed screen. Unslender objects sliding down along the tilted meshed screen are thus separated.
