About Screw Conveyor

Screw conveyor is suitable for transporting powder, granular and small-block materials, such as coal, gravel, sand and lump coal, cement, cereal, and so on. And is not  apply to transportation of perishable, large viscous , easy-to-caking materials.

screw conveyor is bulk material handling equipment, which usually consists of a tube containing either a spiral blade coiled around a shaft (sometimes called an auger), driven at one end and held at the other. The main parts include tube, shaft with spiral blades, inlet and outlet chutes, as well as driving device.

Working principle

The screw conveyor consists of power device, gear box, coupling, screw axis and hanging bearing. The screw axis is made of several sections which connected with spline. Hence, the conveyor hold large load capacity and convenient to dismounting. It is open a besel on the casing to ensure a safe operation.

The material moves along the spiral within the tube. The unique action of the flexible spiral conveyor eliminates the risk of the product separation that can take place in conventional pneumatic conveying systems where mixed materials have components of different densities and particle size.
