ProcessBarron’s rotary airlock feeders, also known as rotary airlock valves, play a critical role in maintaining a reliable ash handling or bulk material handling system. These feeders meter and move fine, sticky, abrasive, and high-temperature materials such as recovery boiler salt cake, pulverized coal, fly ash, bottom ash, sand, and limestone into downstream conveyors, ash conditioners, or pneumatic systems.
Rotary airlock feeder designs, especially modern, engineered versions, offer substantial performance advantages over older flap gates or legacy valves, particularly in cement, biomass, power generation, and recovery boiler environments.
Our rotary feeders are built to handle abrasive, corrosive, sticky, and high-temperature material streams without clogging or excessive wear.
Engineered tolerances and air-tight construction help maintain system pressure and ensure consistent flow into ash conditioners, conveyors, and pneumatic systems.
Rotary airlocks are widely used in ash handling, cement processes, biomass plants, steel mills, and pollution control systems.
Each feeder can be tailored to your system’s size, temperature range, inlet configuration, and material type.
ProcessBarron provides inspections, maintenance, rebuilds, and offers Raumaster Airlock Feeders for applications requiring top-tier European engineering.
