Cast Iron Blow Through Airlock Valve Positive Rotary Feeder
Rotary airlocks displace bulk solids from one vessel or atmosphere to another, while minimizing the loss
of air pressure between them. In pneumatic conveying systems, rotary airlocks are used to charge bulk
solids into the system or to remove them from collection devices (e.g. cyclone or dust collector) at the
end of a system. Pneumatic systems use high-pressure fans or blowers to impart velocity to air thru a
defined circuit of piping, carrying the bulk solids with it thru the system.
Rotary feeder is also called rotary pocket feeder or airlock machine.The structure of normal rotary feedèr
(shown as the picture on the right) is that a rotor with several blades in acylindrical case. The material feu
