What it is

Rotary vane feeders are positive-displacement bulk feeders that regulate flow from hoppers or cyclone outlets while maintaining pressure differentials (critical in pneumatic systems). Multiple variants such as Square D Type and Square BT Type are available for different operational needs.

Typical applications:

• Feeding material into pneumatic conveyors
• Hopper/ cyclone discharge with sealed flow
• Dust collector discharge units
• Metering feed into processing lines

Why it matters

• Maintains conveyor pressure balance
• Positive, smooth product feed
• Reduces air leakage and material degradation
• Different impeller designs for various materials
