Screw conveyor in the form of transmission is divided into shaft screw conveyor and shaft-free screw conveyor two, in the shape of u-type screw conveyor and pipe screw conveyor.Shaft screw conveyor is suitable for non-viscous dry powder materials and small particle materials (such as: cement, fly ash, lime, grain, etc.) while shaft screw conveyor is suitable for viscous and easily wound materials.(for example, sludge, biomass, garbage, etc.) the working principle of screw conveyor is that the rotating screw blade pushes the material to carry out the screw conveyor transmission. The force that makes the material not rotate with the screw conveyor blade is the weight of the material and the friction resistance of the screw conveyor shell to the material.The spiral blade welded on the rotary shaft of the screw conveyor, the surface type of the blade has the solid surface type, the belt surface type, the blade surface type and so on according to the different transportation materials.The spiral shaft of the screw conveyor has thrust bearing at the end of the direction of material movement to give axial reaction force to the screw with the material. If the length is longer, the intermediate hanging bearing should be added.
