It is compact, reliable in operation, with good sealing and wear resistance. The working principle of the rigid impeller feeder is that when the impeller is driven by the transmission mechanism to rotate within the body, the 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 discharge as the impeller rotates. Throughout the entire working process, it enables continuous and quantitative feeding and discharging.The star discharger device is the main equipment for ash discharge in dust removal equipment, air supply, and feeding for other equipment. The star discharger is suitable for powdered and granular materials. It is widely used in environmental protection, metallurgy, chemical, grain, food, and other industrial sectors.The star discharger (also known as rigid wheel feeder, star feeder, airlock, rotary feeder, etc.) is widely used in building materials, metallurgy, chemical, power, and other sectors as the ash discharge device for various dust removal equipment hoppers. It relies on the gravity of the material and the forced action of the feeder's working mechanism to discharge the material from the silo and continuously and uniformly feed it into the next device. It can also serve as the feeding and discharging device for various mills, dryers, silos, and other equipment, suitable for dry powdered and small granular materials.The discharge device is divided into three parts: motor, cycloidal pinwheel reduction, and rotary dragon-type ash discharge valve.By adopting the principle of planetary rotation, the input and output shafts are on the same axis and have the characteristic of being directly integrated with the motor, resulting in a compact structure, aesthetically pleasing and novel design, small size, and light weight. (2) Excellent sealing performance, uniform and stable feeding, smooth discharge operation, low noise, few failures, long service life, and high wear resistance. (3) The bearings and gearbox are far from the valve body, avoiding the effects of high-temperature dust. The front and rear end covers have good sealing performance, preventing dust leakage and extending the service life of moving parts and the lubrication system. (4) Strong overload capacity, low impact inertia, suitable for frequent starting and reverse rotation.
