Impeller feeder for dry powder material or particulate material in the upper hopper continuously, evenly feed sent to the next device is a dosing device. The valve, also known as star dust unloading valve, open star unloader, rotary feeder. Composed of the body, shaft, blade and reducer. Decelerate the motor to drive the drive shaft and the impeller rotation, so as to achieve the purpose of dumping ash. With blade wear resistance and high performance of the air lock, completely discharge, stable connection, compact features, flexible impeller feeder adoption of a flexible rotor, seal better, and to ensure uniform feed. 
 Impeller feeder is widely used in cement, building materials, chemicals, metallurgy and light industry sectors material system to the material equipment. Impeller to the feeder, bucket elevator uses: the text's tube Venturi tube of the short, the Venturi effect of the principle is when the wind had to block things, blocking things the leeward surface of the side port near the air pressure is relatively low, resulting in the adsorption and lead to the movement of the air .... impeller feeder, bucket elevator use: Diaphragm material is a layer of special fabric and attached to the above, a thin layer of elastomer composition. thickness usually (0.2 ~ 1.1mm), the life of the diaphragm is usually in millions of 
 Steel impeller feeder is widely used in building materials, metallurgy, chemical industry, power industry, and also a dry powder or small particles in the upper hopper for uniform delivery to the device under the then steel impeller feeder, also known as electric rotary discharge valve. steel impeller feeder for the amount of conveying flue dust, pulverized coal and other dry materials (grain size less than 10 mm), transportation equipment.
