Spiral Conveyor is a kind of machinery which uses the motor to drive the spiral revolution, and the material to realize the conveying purpose. It can be horizontal, inclined or vertical transport, with simple structure, small cross-sectional area, good sealing, easy to operate, maintenance easily, easy to close transport and so on. Screw conveyor in conveying form is divided into axial screw conveyor and no axis screw conveyor Two kinds, on the outside type is divided into U-type screw conveyor and pipe-type screw conveyor. The axial screw conveyor is suitable for the adhesive-free dry powder material and the Small granule material. (For example: Cement, fly ash, lime, grain, etc.) and no shaft screw conveyor suitable for conveyor by viscous and easy winding material. (For example: sludge, biomass, garbage, etc.) the working principle of screw conveyor is the rotating spiral vane to carry the material through the screw conveyor transmission, so that the material is not with the screw conveyor blades rotating force is the material itself weight and screw conveyor casing friction resistance to the material. Screw Conveyor rotating axis of the spiral vane, the face of the blade according to the different materials of the delivery of solid surface, belt type, leaf type and other types. Screw conveyor spiral shaft in the material movement direction of the terminal has thrust bearing with the material to screw the axial force, in the longer the captain, should be added to the middle suspension bearing.
