Rotary Airlock

Rotary airlocks are important components of pneumatic conveying systems. Rotary airlock is also known as rotary valve, rotary feeder or airlock feeder. The main function of a rotary valve is to control flow of bulk solids from silo, mixer, cyclone or hopper under gravity, pressure and vacuum conditions.

Application Areas

 

Silo Discharge: 

The rotary valve placed under the silo or dust collection system is used to control the bulk solid discharge.

 

Dosage Control:

By controlling the rotation speed of the airlock feeder, volumetric metering and dosing of granular solids is achieved.

 

Pneumatic Transportation:

The airlock mounted under a cyclone is used for discharging the cyclone.

 

Pneumatic Transportation:

Rotary valves mounted under cyclones, silos or hoppers are used to feed the pneumatic conveying line.


 

Rotary Airlock Models

FT Series

Flow through rotary airlocks are used in wide range of applications.

Flow Through Rotary Valve
BT Series

Blow through rotary valves are used in pneumatic transport systems. They are suitable for tranfering sticky powdered materials.

 

Blow Through Rotary Valve

OS Series

The Off Set type also refered as side entry type rotary feeders are used for preventing crackage of delicate materials like sunflower seed and  peanut. These models are also suitable for hard to shear pellets like nylon or plastic granules.

Rotor Types:

Closed End Rotors

Closed end rotors reduce air leakage. They prevent wear on side covers of airlock when handling abrasive materials.

Close End Airlock Rotor

Open End Rotors

Open end rotors are generally used in blow through type rotary feeders.
