Abstract

An electrodynamic particle separator of the ion bombardment type which utilises a rotating collecting roll 10 and a grid plate 28 having a plurality of ion discharge electrodes 24 positioned about a substantial portion of the collecting roll periphery, to subject a stream of particulate material 20 passing therebetween to an ion field over a substantial length of travel, whereby non-conducting particles 36 retain charge they receive and are thereby attracted to the grounded surface of the collecting roll, while conducting particles 38 lose any charge they receive and continue to fall downwardly under the force of gravity. A movable gate 22 is positioned in the stream of particulate material beneath the ion field to separate the non- conducting particles attracted to the roll and falling substantially beneath it from the conducting particles which fall in their original path. The latter may pass through a second similar separator for further improved separation. <IMAGE>
