How does the rotary feeder operate?
rotary feederCommonly known as impeller feeder, star feeder, air shut-off device, airlock, rotary feeder, star valve, etc. Composed of several blades, casing, seals, motor, reducer, etc. carried by the rotor. When the rotor rotates in the cylindrical shell, the material falling from the upper hopper due to its own weight is filled in the space between the blades and discharged to the lower part as the rotor rotates, and then the material is uniformly and continuously conveyed.
The rotary feeder is a key equipment in pneumatic conveying systems. For positive pressure conveying systems or negative pressure conveying systems,Rotating feederIt can uniformly and continuously feed the conveying pipe. Rotary feeders are highly suitable for positive and negative pressure pneumatic conveying systems, pulse dust removal equipment, and fine feeding. The rotary feeder has the characteristics of compact structure, beautiful appearance, stable operation, uniform feeding, and simple energy saving. And it can play a role in supplying air and locking airflow. Due to the low-speed rotation of the rotor and the small gap between the rotor and the inner cavity of the housing, the reverse movement of the airflow is effectively blocked, thereby ensuring the stability of the air pressure in the system and the normal discharge of materials.

1. Unloader, also known as star shaped ash discharge valve, star shaped discharge device, rotary feeder, airlock valve, air shut-off device, and unloader. Generally speaking, the structure of star shaped unloading ships consists of rotor impellers with rare blades, shells, seals, reducers, motors, etc.
When the material in the feeding bin falls due to its own weight and fills the gaps between the blades, the material is discharged from the lower part as the blades rotate, so that the star shaped unloader can discharge it continuously and quantitatively.
3. Star shaped pressure reducers are commonly used in force output systems. For pressure output systems or negative pressure output systems, star unloaders can uniformly and continuously feed the conveying pipe, ensuring that the gas and solid inside the output pipe are relatively stable, and enabling the normal operation of force conveying. Together, the upper and lower air pressure of the ship unloader can be separated, serving as an air lock. Therefore, star shaped ship unloaders are commonly used important components in power transportation systems.
4. The star shaped unloader can be used as a material bin unloader in the material collection system. The star shaped ship unloader is currently the most advanced unloading equipment in China and is also one of the important equipment commonly used in dust removal systems. Especially suitable for dust and small particle materials, it is highly selected for industrial engineering projects such as environmental protection, metallurgy, chemical industry, grain, cement, road construction, drying equipment, etc.
blowerPress air into the conveying pipe, and the material is supplied from the feeder. The mixture of air and material is compressed along the conveying pipe to the discharge point, and the material is discharged after passing through the separator. The air is purified by the dust collector and then discharged into the atmosphere.
Mixed type. It is a combination of the above two methods, and can generally transport loose materials except for materials that are fragile, highly viscous, abrasive, and prone to chemical changes that require special treatment. The disadvantage is high energy consumption, which has certain limitations on the block size, viscosity, and humidity of materials. The blower noise in the pneumatic conveying system is loud, and the pipeline is prone to wear during pneumatic conveying and grinding of materials.
