Negative Pressure Pneumatic Conveying
Negative pressure pneumatic conveying system is a material transportation method that uses a vacuum pump or fan to generate a pressure below atmospheric pressure in a closed pipeline to suck materials from one place to another.
The negative pressure system mainly uses the vacuum generated by the vacuum Roots blower (or vacuum pump) in the sealed pipeline to feed the material through the suction nozzle (or star feeding valve and mixing acceleration chamber unit) with an air flow lower than the outside atmospheric pressure. Then it is mixed with air and sucked along the conveying pipeline to the cyclone separator (commonly known as sakron) for gas-solid separation to realize material transportation from low or bulk locations to one or more high points. Its characteristics are that the material does not leak out, does not cause environmental problems, and the feeding device is relatively simple.

Real cases of Negative Pressure Pneumatic Conveying
Suitable for centralized transportation from multiple places to one place. There can be one or several feeding points, and the feeding pipe can be equipped with one or more branch pipes. Not only can materials from multiple feeding points be transported to the unloading point in sequence, but materials from multiple feeding points can also be transported to the unloading point at the same time.
Under the action of negative pressure, the material is easily sucked in, so the feeding at the throat is simple. The hopper can be opened for continuous feeding and conveying.
Materials are conveyed under negative pressure, and moisture is easy to evaporate. Therefore, materials with higher moisture content are easier to convey than pressure-feeding. Materials supplied under heating can be cooled by conveying.
Components must be kept sealed, and the structures of domestic separators, dust collectors, air locks and other components are relatively complex.
The fan is located at the end of the system, requiring a high degree of air purification.
