Screw conveyor is a kind of continuous transmission equipment which without immunity traction components, it uses rotation screw to convey material. The screw conveyor is of simple structure, low marking cost, strong sealing, safe ,convenient operation and other advantages, It allows multiple inlets and outlets. It is widely used in various industrial department(such as building materials, chemicals, electric power, metallurgy, coal, mine, food and other industries)to convey powder, granular and lump material, such as, coal, ash, slag, cement, food, etc. The temperature of material is less than 200oC. Screw conveyor is not suitable for transporting those material which is perishable, with big viscous and easy caking. In the concrete mixing plant screw conveyor's effect reflected to the fullest.
Loose materials such as powder, granular and small piece material , which includes: clay powder, pulverized coal, coffee bean, sand, grain, cherry , cobble, and cast iron filings, ice, etc.
It is widely used for the grain transportation and some corrosion resistance of the material.
