AERODYNAMIC PLANT FOR ENRICHING LOOSE MATERIALS Russian patent published in 1995 - IPC

FIELD: mining, chemical and other industries. SUBSTANCE: aerodynamic plant consists of technological blocks. Charging and unloading bunkers, vibration bunker, aerodynamic tunnel introduced into the dynamic separation chamber with deflecting vibration shield are mounted in the blocks. The plant is equipped with heaters set up in the vibration bunker, with electric separator and vertical separation chambers mounted one after another into which the aerodynamic tunnel is introduced. The vibration bunker and the vertical separation chambers are connected with the aspiration system by air ducts. The aerodynamic tunnel is made as zigzag. A sieve and checkered reflectors-shelves are mounted in the vibration bunker. Vibrating chutes with opposite lying heaters having reflectors are set up in the dynamic separation chamber. The inner surface of the dynamic separation chamber has a layer resistant to wear and made of silicone for example. The electric separator is made as a drum, a constant-current source, a mechanical brush and corona electrodes with power cylinders and with an additional vibration bunker in the form of T-joint with balancing partitions. The middle vibration bunker from T-joint is connected with the aerodynamic channel by a branch pipe. The rest are connected with transporters. The aerodynamic tunnel is made of the material resistant to wear, fiber glass for example, as C-shaped members checkered in the height of the vertical separation chambers with perforated ends and power cylinders connected with the vertical separation chambers. EFFECT: enhanced efficiency of enriching loose materials. 4 cl, 2 dwg
