Positive-pressure dense-phase pneumatic conveying uses compressed gas as power source, uses forced pneumatic conveying and relies on closed pressure vessel (sending tank) as transmitter. Generally, the pressure of gas source is 0.5 Mpa-0.7 Mpa, and the operating pressure is 0.3-0.5 Mpa. The delivery tank can only adopt clearance conveying mode, and the conveying distance can reach more than 1000m.

    Due to the effect of pressure, the material enters the conveying pipe from the sending tank, and the compressed gas opens and closes at a certain frequency through the solenoid valve to form a pulsed air flow (air knife). With the help of the air knife pressure greater than the pressure of the sending tank, the material is cut into a material bolt. The material is pushed forward by the static pressure difference before and after the bolt. After the material is separated by the separating device, the material falls into the bin and the gas is discharged into it.

 Product characteristics：

1. Low flow rate but high conveying capacity has little effect on material quality.
2. The system has high pressure and low gas consumption.
3. Automation of control system, high requirements for various electrical components;
4. Multi-point feeding and multi-point unloading;
5. The sending tank (also known as the warehouse pump) is a pressure vessel, which is a mandatory equipment.
6. The air source is generally screw air compressor, and the post-processing equipment must be matched.
7. The system is reliable and less maintained, but requires high quality of operation technicians.
