METHOD OF TRANSPORTATION OF HIGH CONCENTRATION LOOSE MATERIALS IN GAS MIXTURE Russian patent published in 2002 - IPC

FIELD: pneumatic transportation. SUBSTANCE: proposed method of loose material transportation includes delivery of compressed gas through branch pipe into chamber feeder for aerating loose material with this gas, additional supply of gas flows spaced over length of transportation pipeline through activators with turning of lows at angle and with lead of helix to provide helical motion of material. Compressed gas is delivered into chamber feeder is swirled state through said branch pipe with possibility of swirling material-and-gas mixture and delivery of swirled mixture into transportation pipeline in which helical motion of material formed at transportation along pipeline is maintained by delivery of said flows at angle and with lead equal to parameters of said helical motion of material. EFFECT: reduced power consumption. 2 dwg
