VENTURI (EJECTOR) FEEDER EP

A Venturi feeder is determined to pneumatic conveying of dry and loose powder and

fine grain materials. Feeder feeds material continually under pressure of conveying air

(gas) to pneumatic conveying

pipeline. Ejecting effect of

conveying air stream decreases

pressure in inlet chamber so

conveyed material is fed into conveying

pipeline. Used construction parts are pipeline

parts; the feeder is in light of inside

overpressure in conformity with regulation No.

26/2003 and is considered as a pipeline that

isn’t a pressure device. Temperature of ambient

temperature isn’t limited.

Venturi feeder is delivered in both, standard and wear

proof design with mixing chamber of cylindric or T shape.

Wear proof design has inner parts in contact with material

stream made of Si - ceramics. The conveying pipeline leads from the feeder body

horizontally or is inclined up. The air nozzle is movable to set the air stream ejecting

effect.
