Screw conveyor is widely used in various industries, such as building materials, chemicals, electric power, metallurgy, coal, grain and other industries, for horizontal or inclined conveyor dust, granular materials and small block, such as coal, ash, slag, cement, food, etc. The material temperature is less than 200 °C.

It is not suitable for conveying perishable, viscous, easy caking materials.

 

The  material feed into the casing and screw flight was hold back by the frication resistance acted on the wall of casing during running, the screw flight push the material and make the material do axial movement, simultaneity the clockwise and counterclockwise fight act as mixer. The material can be discharged at the proper outlet at the bottom of casing or transport out at the end of chute. Conveyor with simple construction, be able to feed and discharge in many position, it is easy to operate, have good seal capability and environmental friendly.

The Main Features of Screw Conveyor:

1. simple structure, small cross-sectional size and low cost;.

2. easy to load or unload .

3. The operation is simple and convenient;.

4. the transport process of materials from the outside world, sealing well.
