Industrial airlocks, also known as rotary airlock valves or rotary feeders, are essential components in bulk material handling systems. Their primary function is to transfer materials from one chamber to another while preventing air leakage, maintaining system pressure and efficiency.
These machines consist of a rotor with multiple vanes rotating inside a housing, allowing material to pass through while sealing air gaps.
They are widely used in:
- Flour mills (chakki plants)
- Cement and fly ash handling
- Food processing and grain industries
- Dust collection systems (cyclones & bag filters)
Key Features:
- Continuous material discharge
- Maintains pressure/vacuum in system
- Reduces air leakage and energy loss
- Available in CI, MS, and SS construction
- Low maintenance and long service life
Airlocks are critical in systems where material flow and air sealing must work together, especially in pneumatic conveying and dust control setups.
