Rotary feeders (also known as rotary airlocks or rotary valves) are essential components in bulk material handling systems. Primarily used for discharging bulk solid material from hoppers, receivers, and cyclones into pneumatic conveying systems, these valves ensure efficient material flow and pressure sealing.
Typical Materials Handled: Cement, ore, sugar, minerals, grains, plastics, fly ash, flour, gypsum, lime, coffee, cereals, and more.
The Round Flange Rotary Valve is a drop-through model suitable for both positive and negative air pressure systems. It is an ideal solution for ventilation and dust removal systems.
