A rotary airlock (also known as a rotary feeder or rotary valve) consists of a housing, a rotor and shaft assembly, two end plates, seals, bearings, a motor, and a drive assembly. When assembled, the rotary airlock functions like a rotating paddle wheel inside the housing, transferring dry bulk solids from the top (inlet) to the bottom (discharge) during rotation.

Literally serving as an air lock between its inlet and outlet ports, the airlock prevents airflow through its vanes and pockets while continuously moving material in a rotating motion.

Airlocks play a vital role in material conveying and processing systems. An improperly selected or applied airlock can result in poor efficiency, increased maintenance, higher labor costs, product degradation, equipment wear, frequent replacements, and production losses due to unplanned shutdowns. The annual cost associated with any of these issues can easily surpass the initial cost of the equipment.

Capacity (t/h) = [Volume (L) × Speed (rpm) × 60 × Density (t/m³) × Fill Factor (%)] / 1000.
