Mission-Critical Flow Control for Modern Cement Plants
In a cement plant, stability is engineered, not assumed. Rotary Air Locks are mission-critical components that directly influence kiln efficiency, energy consumption, dust control, and emissions performance. From raw material grinding to clinker discharge, pressure integrity and controlled material flow are fundamental to continuous cement production.
What This Industry Demands
Fine abrasive raw meal and high dust loading across multiple zones
Critical false-air sensitivity in kiln and preheater thermal zones
High-temperature discharge at preheater, calciner, and clinker cooler points
Continuous 24/7 production cycles with zero tolerance for instability
Pressure differential management between process zones
High wear from abrasive clinker, limestone, and raw meal
Where We Apply in Cement
Kiln Feed Systems
Stable and pressure-sealed volumetric feeding into the rotary kiln for thermal efficiency, flame stability, and consistent clinker quality.
Preheater & Calciner Discharge
High Temperature Series rotary air locks with outboard bearing protection, thermal gap management, and heat-resistant sealing for elevated temperature zones.
Vertical Roller Mills (VRM)
Precision air sealing at VRM discharge that protects mill air balance, separator performance, and downstream pneumatic conveying stability.
Baghouse Dust Collection
Leakage-controlled discharge beneath bag filter hoppers that preserves filtration efficiency and supports environmental compliance.
AFR Feeding
Reinforced heavy-duty and abrasive series valves for controlled, pressure-sealed feeding of RDF, biomass, tyre chips, and other heterogeneous alternative fuels.
Waste Heat Recovery Systems (WHRS)
Pressure-zone isolation at WHRS discharge points to reduce air infiltration losses and protect thermal recovery and turbine performance.
In cement plants, air leakage is not a minor issue, it is an energy penalty. Uncontrolled leakage can increase fuel consumption, reduce kiln thermal efficiency, destabilize combustion control, lower mill performance, increase dust emissions, and impact environmental compliance. Precision sealing directly supports plant productivity and sustainability goals.
