Due to its specialization and uniqueness, the air-cushion belt conveyor, in addition to sharing the common characteristics of ordinary conveying machinery, has its own features and development trends, thus forming a new branch within bulk material conveying machinery. Working principle: A pneumatic cushion belt conveyor is a type of belt conveyor that uses a thin air film to support the conveyor belt and the materials on it. It replaces the idlers of a roller belt conveyor with perforated air chambers. When an air source supplies air with a certain pressure and flow rate into these chambers, the air inside escapes through the small holes in the grooves, creating a layer of air at a certain pressure between the conveyor belt and the grooves; this air layer is known as an air cushion, which supports the conveyor belt and the materials on it. It transforms the rolling friction of the idler roller machine into fluid friction using air as the medium, **reducing operational resistance and achieving significant energy savings. Current development status of air-cushion belt conveyors in China ① Widespread use: In China’s grain and oil industry as well as in the development of non-ferrous metals, wherever there is a need for handling large quantities of bulk materials – such as in grain and oil processing plants, grain storage facilities, bulk grain logistics companies, and port and warehouse operations – air-cushion belt conveyors have been widely adopted in recent years as the primary conveying equipment for storing and transporting alumina powder, which is used as a raw material. ②The advanced nature of its conveying technology: Over the past 20 years, air-cushion belt conveyors have been widely used in China, particularly in large logistics and warehousing companies located in ports and docks, and their unparalleled advantages have been demonstrated, such as being environmentally friendly ； High capacity ； Low energy consumption ； Long service life ； Low subsequent maintenance costs ； High comprehensive benefits ； ③In terms of creativity in applications, since the introduction of air-cushion belt conveyors in the 1980s, over these 40 years of development, outstanding enterprises in our country have invested a great deal in research, improvement, and innovation. In particular, there have been significant improvements in aspects such as the appearance, structure, hole arrangement, and air supply of air-cushion belt conveyors. Especially in recent years, as environmental protection requirements have increased, companies that produce air-cushion belt conveyors have invested a great deal of effort in research related to environmental-friendly sealing, resulting in rapid progress in this area.
