Rotary Air Lock

Rotary Air-lock Valves are used at the bottom of Bins, Cyclones, Dust Collectors or Feed Hoppers to discharge materials at a controlled rate or act as an Airlock. They are also used to introduce materials into positive or negative conveying systems. A Rotary Feeder / Airlock Valve consists of a rotor which turns at a given RPM in close clearance to it’s casing thus maintaining a uniform rate of material flow and provides a seal. TheRotary Air-locks provide reliable service in high pressure, high temperature and other severe service conditions. The valves can be used in various industries such as food, plastics, chemical, asphalt, mining, baking, cement and paint.

Rotary Air-Locks are usually used to accomplish 3 basic tasks:

a)to feed material from bins or hoppers.

b)To deliver fines from the collector while sealing against air loss.

c)And to feed material to pneumatic conveying line against pressure
