Introduction With the pressure tank as the essential component, after calculation is done within the tank, the pressure tank pneumatic conveying equipment forces the powder or particles into the transporting pipeline with compressed air for further transmission. The transmission has flexible directions, strong capacity and long distance, suitable for large scale, long distance transporting of the quantity powder or particles.   Characteristics 1. Fully hermetic operation 2. No dust flying, no leakage or blockage 3. High solid-gas ratio, strong transmission ability and long conveying distance 4. Calculation realized with the pressure tank 5. Total pneumatic control, easy for automation 6. Reliable operation with no moving parts
