Rotary Airlock Valve

Rotary feeders, also known as rotary airlocks or rotary valves, Rotary airlock feeders have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used.. Rotary feeders are primarily used for discharge of bulk solid material from hoppers/bins, receivers, and cyclones into a pressure or vacuum-driven pneumatic conveying system. Components of a rotary feeder include a rotor shaft, housing, head plates, and packing seals and bearings.

Rotors have large vanes cast or welded on and are typically driven by small internal combustion engines or electric motors.These valves can handle 2 liter /revolution to 425 liter /revolution, i.e. 1 TPH to 300 TPH. Two Types of Rotary Airlock Valve.

Mechtech India blow through series are suitable for plastics, flour, food, grain, chemical and milling industries. These valves are specially designed for pneumatic conveying systems to achieve a easy and smooth flow of materials. Suitable for non-abrasive product and can eliminate pressure drop to very minima.

Rotary Valves are designed for maximum versatility in application. They are suitable for controlled discharging and feeding of powdery or granular materials from silos, hoppers, pneumatic conveying systems, bag filter houses, or cyclones.
