pneumatic conveyor is an advanced material conveying machine. It is compact, flexible and labor-saving. It can load and unload quickly and easily. It can convey by positive pressure separate or suction by vacuum separate or convey by positive and vacuum pressure at the same time after a simple combination. It can be used to convey granular materials on horizontal, inclined and vertical such as soybean, rice, wheat, corn, sorghum, barley malt, plastics and resins etc.
Pneumatic conveyor is widely used to handle materials in bulk loading, bulk conveying, bulk unloading, silo to silo, stack to stack in barn, farm, railway stations, docks, grain processing and brewing industries. When using this machine to convey grains, grains have to be selected and dehydrated.
Working priciple of pneumatic conveyorÂ
Pneumatic grain conveyor is composed of the high pressure blower, air flow control valve, separator tube, air locker, connecting pipe, suction nozzle and conveying pipelines and other components. Its working principle 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 or the dust collector.
