AERODYNAMIC INSTALLATION FOR THE ENRICHMENT OF DISPERSED MATERIALS Russian patent published in 1994 - IPC

FIELD: mining industry. SUBSTANCE: material enters booster pipe 3 in small amounts. By means of air flow the particles are displaced in the vortex flow. The vorticities are formed by conic rings 4. Then the material arrives into dynamic chamber 5 with deflecting shield 7. Large-sized particles knock against shield 7 and settle down in the lower part of the chamber getting rid of the dust. Small-sized particles are carried out of chamber 5 into set in-line bunkers 8 with shields 9 where they settle down too. Light particles are carried out into cylinder 10 by the aspiration system. EFFECT: simpler design of devices for the enrichment of loose materials. 4 dwg
