Introdcution
The Blow Through Rotary Airlock feeder used in pneumatic conveying of positive pressure applications only. Instead of a typical outlet, blow thru rotary airlocks include two ports on the sides of the valve near the bottom. The conveying line pipe connects directly to the valve, with the air stream flowing through the rotor pockets. This design is very efficient, and works wellon powdered materials .However, this valve is not recommended on pellet products as the vanes and inside house will quickly wear (For pellet material, we have drop through type ). With special designed hopper, it works more efficiently.
