1. application:
Rotary airlocks are important components of pneumatic conveying, bulk solids handling and batching systems. The air-locked valve is widely used in conveying materials and dust collecting in industrial field

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. Airlocks can work on pressure and vacuum applications.

2. typical discharge material:
Wheat, flour, barley, oat, rye, bran, chaff, feed, seed, corn, chickpea, bean, lentil, pea, soy bean, sesame, rice, pice flour, dried fruit, nuts, peanut, almond, sunflower seed, cotton seed, grain cereals, chestnut, coffee grain, coffe powder, sugar, salt, spice, cement, calcite, ash, glass powder, marble powder, plastic pellets, sawdust, pvc, fly ash, coal, coal dust.

3. Characteristics:
- Usually it is composed of three-phrase AC asynchronous motor, motor reducer and rotary valve.
- It can work stably with high efficiency.
- With external bearings and motor-reducer, it can work under 280 °C.
- The material can be cast iron, carbon steel, stainless steel;
- Rotors can be made especially according to users requirement.
- Minimum gap between blade and body can lock the air efficiently.
- Driving method can be direct model or chain model.
- Precision machining of the components.
