AERODYNAMIC UNIT FOR ENRICHMENT OF BULK MATERIALS Russian patent published in 1994 - IPC

FIELD: enrichment of bulk materials. SUBSTANCE: unit has pipes, through which basic material is conveyed via feeders into aerodynamic tube, and magnetic drums for removal of magnetic inclusions. Particles of material are accelerated in aerodynamic tube and fed into separating chamber. Where dust is separated by means of dedusting apparatus and discharged into aspiration system. Impact-inertia part of separating chamber is provided with screen, against which particles of material collide and as a result dust adhered to them is removed. Cleaned material is discharged downward through pipes. EFFECT: increased capacity and enhanced reliability in operation. 2 cl, 1 dwg
