CONCENTRATION TABLE Russian patent published in 2005 - IPC

FIELD: equipment for concentration of minerals, may be used for gravitational separation in flow of fine-grained and sludge ore pulp.

SUBSTANCE: concentration table has supporting frame, drive, rhombic deck with truncated charging and concentrate ends and corrugations extending in parallel with discharge edges for discharge of light fraction, pivotal tie-rod including resilient member including springs or rubber parts, resilient vibrating members made in the form of supporting columns inclined toward drive and adapted for carrying deck fixed thereon through core beam, pulp receiver, narrowing chamber adapted for preliminary concentration and equipped with corrugations provided on side wall and extending in parallel with deck corrugations, and threshold system for discharge of preliminarily enriched concentrate, washing-away water distributor, and enrichment product collecting chute. Deck is divided lengthwise of concentration table into two symmetrical equal working parts movable in transverse direction and equipped with spacer columns for adjustment of their transverse angle of inclination. Spacer columns and supporting columns under concentrate end of deck include jacks, which may be of mechanical or hydraulic type.

EFFECT: simplified construction, increased capacity, effective separation process, and reliable operation of concentration table.
