Rotary feeder working principle

The rotary feeder is also called rotary valve, star discharger, air lock, air shut-off, the usual rotary feeder structure is a rotor with several blades rotating in the cylindrical casing, the material falling from the upper hopper, filled in the space between the blades, and discharged with the rotation of the blades to the lower part, the side of the fuselage is equipped with a constant pressure suction port, which can suck away the high-pressure gas brought by the rotation of the impeller from this mouth. Reduce the phenomenon of gas ejecting, which is conducive to the smooth falling of materials. For the pressure and suction pneumatic conveying system, the rotary feeder is one of the main components, which can supply the material into the conveying pipe evenly and continuously, and in the separation and dust collection part of the system, it has the function of unloader.
