CENTRIFUGAL SEPARATOR Russian patent published in 2009 - IPC B03B5/32 

FIELD: technological processes.

SUBSTANCE: invention is related to devices for enrichment of ores and may be used for separation of granular materials according to density. Centrifugal separator comprises two conic cups of different diametres, which are installed coaxially and connected to electric drive. Separator is additionally equipped with the second electric drive. Cups are connected to different electric drives with the possibility of their independent rotation. Conic cups are installed one inside another. On side surface of internal conic cup, slots are arranged, which are installed vertically along cone generatrix, and on its external surface, vanes are fixed vertically, which produce speed-up device. Height of internal conic cup makes 2/3 of internal conic cup height. Internal surface of external conic cup is arranged with corrugations, height of which reduces to its upper part.

EFFECT: higher efficiency of material separation.
