Rotary Feeder
A Rotary Feeder — also known as a Rotary Airlock or Rotary Valve — is a continuously rotating device that discharges bulk material from dust filters, cyclones, hoppers, and bins while maintaining an airtight seal between two pressure zones. It is a critical component in any aspiration or pneumatic conveying system — without it, the pressure differential collapses and the entire system loses effectiveness.
Key Functions
- Airlock seal between two pressure zones for aspiration and pneumatic conveying systems
- Continuous, controlled discharge from dust filters, cyclones, hoppers and bins
- Metering device — accurate control of feed rate into downstream equipment
Configurations
- Mild Steel construction for general bulk material handling
- Stainless Steel construction for hygiene-critical applications
- VFD-compatible for automated, variable feed-rate control
- Sized to match aspiration airflow and dust loading of the connected equipment
