Air-cushion belt conveyor, due to its professionalism and speciality, has its own characteristics and development trends in addition to the commonality of general conveying machinery, so it has also formed a new branch of bulk material conveying machinery.
​​
working principle
​​
The air cushion belt conveyor is a belt conveyor that uses a thin air film to support the conveyor belt and the materials on it.
​​
It replaces the idler of the idler belt conveyor with a perforated air chamber. When the air source provides air with a certain pressure and flow into the air chamber, the air in the air chamber escapes through the small holes on the pan groove, and the air in the air chamber escapes. A layer of air film with a certain pressure is formed between the conveyor belt and the disc groove, which is called an air cushion, which supports the conveyor belt and its upper material.
​​
The rolling friction of the roller machine is changed into the fluid friction with air as the medium, which greatly reduces the running resistance and has a significant energy saving effect.

The development status of domestic air cushion belt conveyor
​​
① Widespread use
​​
In the development process of my country's grain and oil industry and non-ferrous metals, where there is heavy bulk material handling, such as:
​​
Grain and oil processing enterprises,
​​
Grain warehousing companies,
​​
Bulk grain logistics enterprises,
​​
Port and wharf warehousing enterprises
​​
In particular, in recent years, a wide range of aluminum companies have generally selected air cushion belt conveyors as the main conveying equipment for the storage and logistics of raw alumina powder.
​​
②Advancement of conveying technology
​​
During the extensive use of air-cushion belt conveyors in China for nearly 20 years, especially in the application of large-scale logistics and warehousing enterprises in ports and terminals, its unparalleled advantages have been proved, such as:
​​
Green;
​​
large volume;
​​
Low energy consumption;
​​
long lasting;
​​
Low maintenance cost later;
​​
High comprehensive benefit;
​​
③Creativity in application
​​
Since the introduction of air-cushion belt conveyors in the 1980s, in the 40-year development process, my country's outstanding enterprises have invested a lot of research, improvement and innovation.
​​
In particular, the appearance, structure, hole layout and air supply of the air-cushion belt conveyor have been significantly improved.
​​
Especially in recent years, the requirements for environmental protection have increased, and air-cushion belt conveyor companies have also invested a lot of research in environmental protection and sealing, and have also developed by leaps and bounds.
