<p>Chips (8) of magnetic material are separated from a mixture (7) of such chips (8) and chips (9) of non-magnetic material by the chip mixture (7) being supplied to a plane run (3a) of an endless conveyor belt (3) which in this run passes over a fixed magnetic plate (5). The magnetic plate (5) is arranged close to the plane run (3a) and supports a plurality of permanent magnets, which are adapted to retain the chips (8) of magnetic material on the conveyor belt (3). The magnets have such alternating polarity and are positioned in such a manner on the magnetic plate (5) that, as the conveyor belt (3) moves over the megnetic plate (5), flinging motions are imparted to the chips (8) of magnetic material to release chips (9) of non-magnetic material connected to these chips. The plane run (3a) of the conveyor belt (3) is oriented in such a manner that the major part of the chips (9) of non-magnetic material, which are released from the chips (8) of magnetic material as the conveyor belt (3) moves over the magnetic plate (5), fall freely from said one side of the plane run (3a) without falling back on the conveyor belt (3).</p> |
