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

FIELD: mining, chemical and other industries. SUBSTANCE: aerodynamic complex for enriching loose materials consists of blocks. Vibration chute 1 connected with charging bunkers 2 and crusher 3, overloading branch pipe 4 and elevator 5 which is connected with the vibrating dryer containing overloading bunker 6, is mounted in the blocks. Sieves 7 of classification, heaters with reflectors 8, inclined shelves 9 on vibrating housing 10, dust exhaust fan 11 with air duct 12 are also set up in the blocks. The vibrating dryer is mounted over vibrochamber 13 of roasting and vibrochamber 14 of electropulse processing which are connected with zigzag aerodynamic tunnel 17 by vibration chute 15 through iron separator 16. On one side tunnel 17 has pneumatic blower 18, on the other side it is equipped with inclined deflecting movable shields 19, power cylinders 20, constant magnets 21, vibrators 22 and vertical chambers 23 of rarefaction. Dynamic chamber 24 of separation is equipped with air-tight chamber 25 for separating the small fraction and with T-joint having throttle valve 26 in the center. Air duct 27 from it is introduced into chambers 28 for separating dust particles with movable deflecting shield 29 which are connected with an aspiration system. The complex is equipped with a plant for the gravitational separation of particles with swinging partitions and stock-rooms which are connected between themselves by transporters 34. The regulation of the complex is exercised from control desk 35. EFFECT: facilitated manufacture. 4 dwg
