 Working principle of pneumatic vacuum grain conveyor 

The working principle of pneumatic vacuum grain conveyor is negative pressure air stream generated by the high pressure blower though the suction nozzle, suctioning the materials into the hose tube, then materials through the separation tube, air and material separated, material fell off into the air locker downward, then materials will be conveyed to the required place by positive pressure air flow. The air separated will go into the blower through the separator tube (RB-20 and RB-30 through the dust collector).
