Date Feb. 11, 1988.An apparatus for the separation of a mixture of particulate material having particles of substantially the same particle size. The apparatus comprising a wind tunnel (10) having an entry and an exit. The exit is associated with a fan (14) for creating an air flow through the wind tunnel (10) from the entry to the exit. An inlet (18) is provided at the top side of the wind tunnel for introducing the particulate material into the wind tunnel whereby it can fall freely under the influence of gravity transverse to the air flow. A plurality of collectors (20) are spaced axially along the bottom of the wind tunnel, each collector extending transversely across the wind tunnel.</p> |
