The segmented wheel air-lock ash discharge valve rotary feeder features an aesthetically pleasing and elegant design. The rigid impeller feeder consists of a rotating impeller with compartments, a body, and a new type cycloidal pinwheel reduction motor, among other components. It is compact in size, reliable in operation, and offers excellent sealing and wear resistance. The working principle of the rigid impeller feeder is as follows: when the impeller is driven by the transmission mechanism to rotate within the body, powdered or granular material falling from the upper separator (or hopper) enters the impeller compartments through the feed port and is conveyed to the discharge port for expulsion as the impeller rotates. Throughout the entire process, it enables continuous and quantitative feeding and discharging.

The star-shaped discharger device is a primary equipment for ash discharge in dust removal systems, air supply, and feeding for other devices. The star-shaped discharger is suitable for both powdered and granular materials. It is widely used in environmental protection, metallurgy, chemical, grain, food, and other industrial sectors.

The star-type discharger (also known as rigid wheel feeder, star-type feeder, airlock, rotary feeder, etc.) is extensively applied in building materials, metallurgy, chemical, power, and other sectors as an ash discharge device for the hoppers of various dust removal equipment. It relies on the gravitational force of the material and the forced action of the feeder's working mechanism to discharge material from the silo and continuously and uniformly feed it into the next device. It can also serve as a feeding and discharging device for various mills, dryers, silos, and other equipment, suitable for dry powdered and small granular materials. The segmented wheel air-lock ash discharge valve rotary feeder boasts an aesthetically pleasing and elegant design.
