After more than ten years of use, the excellent characteristics of air suspension conveyor have been fully demonstrated. Now it has been widely used in mining, coal, metallurgy, building materials, grain, chemical industry, port and other industries. It uses air film to support the conveyor belt and is used to convey density of 0.5~2.5t / m 3 For loose materials such as block, granular, and powder, the air suspension belt conveyor replaces the rollers of the loaded branch of the general belt conveyor with an air chamber, and sends pressurized air into the air chamber through a fan. The air escapes through the air holes in the air chamber disc groove, and forms a very thin air film between the carrying belt and the disc groove to hold up the carrying belt and the material. It has the characteristics of safety, environmental protection, high efficiency, not easy to deviate, and a long service life of the conveyor belt. In actual use, because the airflow in the disc groove air holes has a large air pressure to hold up the material on the carrying belt, after long-term use, the air holes are flushed by the air flow for a long time, the air hole diameter becomes larger, resulting in a decrease in air pressure, affecting the normal transportation of the carrying belt.
