FIELD: transport.
SUBSTANCE: invention relates to equipment for pneumatic handling of loose and fine materials. The system includes material charging unit and discharging unit, expander-tube pump with air bottom containing charging tube for material top-loading, valve for compressed air release, valve for replacing air feed, level sensor, electric-contact manometer, disk shutter and transmission pipeline. Additionally, the system contains flow stabiliser(s) installed in pipeline at intervals not exceeding 100 m on the level from disk shutter to discharging unit, and pneumatic manifold of expander-tube pump. Air bottom of expander-tube pump is made as air elements of the main pressure air unit located in chamber cone and as air elements of auxiliary aeration unit, which elements are located in discharge tube. Stabilisers are performed as insert made of metal strip initial section of which is bended at an angle of 180 degrees.
EFFECT: invention provides lowering energy consumption for material transportation due to lower relative blowing rate.
