Screw conveyors and conveying formally divided into two kinds of shaftless screw conveyor screw conveyor shaft, in the shape into a U-shaped and tubular screw conveyor screw conveyor. Shaft screw conveyor is suitable for non-sticky powder materials and small particles of material (for example: cement, fly ash, lime, grain, etc.) without shaft screw conveyor for easy winding by viscous materials. (Example: sludge, biomass, waste, etc.) screw conveyor works rotating helical blade passage of the material were transported screw conveyor, so that the material does not rotate together with the screw conveyor blade force is the material of its own weight and screw conveyor housing friction of the material. Rotating shaft helical screw conveyor welding blades, blade surface transport of materials depending on the type of entities face, belt surface type, surface type and other types of blades. Screw conveyor screw axis in the direction of movement of materials terminal has thrust bearings with the material to spiral axial reaction force, the longer the captain, should be added to the intermediate hanger bearings.
