Rotary Airlock Feeders

ProcessBarron’s rotary airlock feeders are critical to a reliable ash handling and bulk materials handling system.

Rotary airlock feeders (also called rotary airlock valves) meter and move fine, sticky materials such as recovery boiler salt cake, pulverized coal, fly ash, bottom ash, sand, and limestone to conveyors or ash conditioners. Rotary airlocks also have several pollution control applications in many industries. Learn more about our ash handling products and services here!

Key Advantages of Rotary Airlock Feeders

From enduring the temperature intensity, to the demands of maintaining pressure requirements, rotary airlock feeders must function reliably to ensure ash handling efficiency and environmental compliance for your plant. Constructed from heavy-duty carbon steels, stainless steel, or abrasion-resistant steels, these premium air-tight rotary feeder designs feature shallow rounded pockets that prevent material build-up in the rotor and facilitate improved flow. 

Additionally, these rotary feeders have shear-pin overload protection, convenient clean-out access doors, and can operate at various speeds through simple sprocket modification. Rotary airlock feeder designs, particularly new-generation designs, have proven to be significantly more reliable than flap-gates or older rotary feeders, especially in cement plants. These rotary airlock feeders require a much lower frequency and intensity of maintenance than older alternatives.
