Screw Conveyor System

A Screw Conveyor System is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can be conveyed horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. In terms of conveying form, screw conveyors are divided into two types: shafted screw conveyors and shaftless screw conveyors, and are divided into U-shaped screw conveyors and tubular screw conveyors in appearance. The shaft screw conveyor is suitable for non-viscous dry powder materials and small granular materials. (For example cement, fly ash, lime, grain, etc.) and the shaftless screw conveyor is suitable for conveying viscous and easily entangled materials. (Example sludge, biomass, garbage, etc.) And there are different types of screw conveyors like Auger Conveyor, U Type Screw Conveyor, U Shaped Screw Conveyor, etc. The working principle of the screw conveyor is that the rotating screw blade pushes the material to be conveyed by the screw conveyor, and the force that prevents the material from rotating with the screw conveyor blade is the weight of the material itself and the frictional resistance of the screw conveyor casing to the material. The spiral blade welded on the rotating shaft of the screw conveyor, the surface type of the blade has solid surface type, belt type surface type, blade surface type and other types according to the different conveying materials. The screw shaft of the screw conveyor has a thrust bearing at the end of the material moving direction to give the screw axial reaction force with the material. When the length of the machine is long, an intermediate hanging bearing should be added.
