GRAVITY CONCENTRATOR Russian patent published in 2009 - IPC B03B5/38 

FIELD: mining engineering; mechanics.

SUBSTANCE: gravity concentrator includes a conical chamber with downward facing cone vertex, a central pulp charging tube, which can rotate in said chamber, a nozzle to supply water into lower part of said chamber, and containers to collect light and heavy fractions of material. Concentrator is equipped with a perforated conveyor worm, which is rigidly connected with said central tube and provides for bottom-up pulp transfer within chamber. Nozzle is positioned coaxially with said central tube to create loosening fluid flow, which passes through splitter and filter in the direction opposite to that of the pulp delivered from said tube.

EFFECT: improved efficiency of valuable heavy fraction extraction, improved concentrator throughput.
