CENTRIFUGAL SEPARATOR Russian patent published in 2006 - IPC B03B5/32 B03B13/04 

FIELD: apparatuses for extracting gold and platinum containing sands.

SUBSTANCE: centrifugal separator includes cylindrical housing provided with attachments for discharging light and heavy fractions in the form of cone part filled with liquid non-mixing with mineral suspension; annular accumulator of noble components, tangential branch pipe for supplying mineral suspension made of electrically non-conducting material. Detector for detecting metallic inclusions and connected with delay line is mounted on outer side of tangential branch pipe. In cavity of cylindrical housing shaft with sleeve is arranged. At least four bent blades are rigidly secured to said sleeve; mutually opposite ends of said blades form angle 90°. Horizontal partition is mounted near lower base of cylindrical housing and it is joined through shaft and screw joint with reversing electric motor. Balance beam is secured to shaft and it is joined with rod of regulating shut-off valve. On inner surface of cylindrical housing there are cycloidal casings; on inner surface of cone portion there are curvilinear helical guides communicated with annular accumulator.

EFFECT: enhanced efficiency of separation of mineral suspension.
