Screw Conveyors Are Used In The Chemical Mining Grain And Food Industries

Screw conveyor is a mechanical device that uses a motor to drive a screw to rotate and push materials to achieve the purpose of transportation.

Working principle

The rotating helical blades push and convey the materials. The weight of the materials themselves and the frictional resistance of the casing prevent the materials from rotating along with the blades.

Structural composition

It is generally composed of three major parts: the main body, the inlet and outlet device, and the drive device. The main body is composed of the first section, the middle section and the tail section. The spiral shaft is welded with spiral blades. The blade surface types vary according to the different materials being conveyed, such as solid surface type, belt surface type and blade surface type, etc.

Applicable scope

Applicable for the transmission of powdery materials, granular materials and small piece materials and widely used in tall departments of national economy, such as building material, metallurgy, chemical industry, power, mining, machinery, grain and food.

Screw conveyors is consisted of conveyer body, feeding and discharging hole and driving device; the screw blade of screw conveyer has three modes: hypostatic screw surface, belt screw surface and blade screw surface. Among them, the blade screw surface is used less to transit the condensable materials with high viscosity. But this blade screw also has the function of mixing and integrating to materials. From the angle of materials displacement direction, screw conveyer can be divided into horizontal screw conveyer and perpendicular screw conveyer that are used in the horizontal transmission and perpendicular lifting to all powdery materials, granular materials and small piece materials. This screw conveyer is not suitable to be used to transit the special materials because they are easy to deteriorate and agglomerate with the characters of large viscosity, heat and pressure intolerance and strong causticity.

Product advantage

1.The middle bearing adopts rolling and slipping exchange structure with advantages of good sealing and wearing resistance.
2.Suspension bearing adopts machine outside oil cup, which is convenient for lubricating.
3. The new added electric discharge hole is convenient for automatic controlling.
