ABSTRACT:
A solids separation system is provided, designed for pneumatic separation of pieces of scrap particularly metallic scrap, into light and heavy fractions. The mixture of pieces of scrap is fed into an enclosed separation vessel wherein they fall by gravity into a horizontally directed stream of air blown into and across the separator vessel, whereby the heaviest pieces fall through the air stream into a heavy solids hopper and the lighter materials are carried downstream by the force of the horizontal air stream into a second hopper. A gas outlet port is provided at the top of the vessel thereby imparting an upward velocity vector to the gas. The horizontal velocity of the gas being reduced by expansion, light metal pieces fall out of the influence of the gas stream into the light solids hopper. Means are provided for adjusting the air flow path from the first into the second hopper comprising a pivoted angularly disposed baffle plate defining the rear wall of the first hopper, the surface of which plate also serves to direct solids intercepted thereby into said first hopper.
