Star discharge device is also known as discharger, discharge valve, rotary feeder, air lock valve, usually the structure of star discharge is composed of a rotor impeller with several blades, a shell, a seal and a reducer, Motor and other components. When the material in the upper silo falls under its own weight and fills the gap between the blades, it is discharged at the lower part with the rotation of the blades. Therefore, the star unloader can discharge the material quantitatively and continuously. Star unloaders are commonly used in pneumatic output systems, for pressure output systems or negative pressure output systems. The star discharger can evenly and continuously supply the material to the conveying pipe. To ensure that the gas and solids in the pneumatic output pipe are relatively stable, so that the pneumatic conveying can work normally, and at the same time, the upper and lower parts of the discharger can be separated from the air pressure. And play a role in locking air. Therefore, the star discharger is an important component commonly used in pneumatic conveying systems.

　　 is especially suitable for dust, small particle materials, and is well-received for the selection and selection of engineering projects in environmental protection, metallurgy, chemical industry, food, cement, road construction, drying equipment and other industrial industries.
