Feeders / Airlocks and Rotary Valves


FLSmidth’s heavy-duty feeders, airlocks and rotary valves are field-proven in countless applications. Our feeders/airlocks help maximize the performance and dependability of both pressure and vacuum pneumatic conveying systems.

Our standard feeders and airlocks are constructed of cast iron, or a combination of iron and steel, and are also available in special combinations of stainless steel, aluminum and/or ductile iron.

Feeders and airlocks are available with a special abrasion-resistant ceramic lining for long operating life, reducing downtime and requiring minimal maintenance.
