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.
screw conveyor it is used in transporting powder, block and granular materials, such as flour, grain, cement, chemical fertilizer, ash, sand, stone, coal, etc. It is widely applied to building,
metallurgy, chemical industry, mining, machinery , food, and medicine industry, etc. It is not suitable for conveying materials with perishable, big viscosity and easy to agglomerate beacuse of the
