Introduction of Screw Conveyor

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 othe 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 200°C. Screw conveyor is not suitable for transporting those materials which is perishable, with big viscous and easy caking. In the concrete mixing plant screw conveyor's effect reflected to the fullest. Our company can design and manufacture special models based on your needs.

Application of Screw Conveyor

 Screw conveyor is applicable for transporting powder granular and small blocked bulk material, such as clay powder, cement, concrete, sand, stone, grain, coal etc. It also can complete the gathering, stirring, mixing, dehydrating, customizing material, unloading, stacking during conveyor.

Working Principle of Screw Conveyor

When the hollow axes with screw flight rotate along the jacketed trough, the bulk material feed into the trough and screw flight

was hold back by the frication resistance acted on the wall of trough during running, the screw flight push the material and make the material do axial movement, simultaneity the material contact with the hollow shaft and jacketed trough full with cooling water and do heat transfer process. The cooled material can be discharged at the proper outlet at the bottom of trough or transport out at the end of trough.

Structure Advantages of the Screw Conveyor

A) High quality motor and gear box, with heavy duty design, large torqe and low noise.
B) outside tube complete with one inlet, one outlet, end flange, ball joint , inspection window.
C) standard fitting parts, middle bearing, end bearing, splined shaft coupling
D) Lifting eyes on each tube section, convinient for transport and installtion.
E) small diameter, great efficiency, high throughout rates. .
