PULP ENRICHMENT PROCESS AND DEVICE DESIGNED FOR ITS PERFORMANCE Russian patent published in 1994 - IPC

FIELD: mining-and-enriching industry. SUBSTANCE: feed pulp is supplied to a rotor making rotary and reversible oscillations. The rotor is installed inclined on a support. It has a slide valve arranged above the unloading device. The latter accommodates dissecting knives positioned in steps. Due to the rotor inclination and rotary-reversible oscillations ore particles move to the lower part of the rotor under the action of gravitational and inertia forces. Thus enriched layer is separated. As soon as the mass of the ore reaches the unloading zone, it is divided by the dissecting knife and brought out. During the further movement more intensive separation and division are performed till the layer thickness equal to that of a concentrate is obtained. EFFECT: more efficient ore processing. 5 cl, 2 dwg
