CENTRIFUGAL DRESSING APPARATUS Russian patent published in 2011 - IPC B03B5/32 

FIELD: process engineering.

SUBSTANCE: invention relates to dressing of minerals, particularly, to dressing equipment and may be used for concentration of ore and industrial ferrous and non-ferrous products in fluid medium. Proposed centrifugal dressing apparatus comprises stationary housing, pulp box, and drive shaft supporting hollow truncated cone with smaller base up ward, and impeller. Truncated cone stepped inside section features annular groove made at base of each step. Truncated cone outer surface has holes communicated with annular grooves. Separation deflectors made up of hollow truncated cones with larger bases directed downward are arranged at bottom inner surface, with clearance relative to cone, and fixed on drive shaft. Deflector arranged above that arranged below features larger clearance. Apparatus is provided with three stationary annular separation product boxes.

EFFECT: higher separation efficiency.
