The screw conveyer is divided into two kinds of screw conveyor and non - axial screw conveyor in the form of conveying, which are divided into U type screw conveyor and pipe type screw conveyor. Axle screw conveyer is suitable for sticky dry powder material and small particle material. (for example, cement, fly ash, lime, grain, etc.) and no axle screw conveyer is suitable for sticky and easy to wound material. The working principle of the screw conveyor (such as sludge, biomass, garbage and so on) is that the rotating spiral blade conveys the screw conveyer by the spiral blade, which makes the material not rotating with the blade of the screw conveyer is the weight of the material itself and the friction resistance of the screw conveyer's shell to the material. The surface of the spiral blade welded on the rotating shaft of the screw conveyer has the shape of the solid surface, the belt face type and the blade face type according to the different conveying materials. The spiral shaft of the screw conveyer has the thrust bearing at the end of the material moving direction to screw the axial force with the material. In the long time, the middle hanger bearing should be added.
