　　Harbin shaftless screw conveyor manufacturer

　　Working principle

　　Using rotating spiral blades to push and transport materials,while the weight of the material itself and the frictional resistance of the screw conveyor casing prevent the material from rotating together with the spiral conveyor blades.

　　Compared with traditional screw conveyors with shafts,the shaftless screw conveyor has the outstanding advantage of strong resistance to entanglement due to the use of a non central shaft design and the use of a flexible integral steel screw to push materials.

　　Classification

　　Spiral conveyors are divided into two types in terms of conveying form:axial spiral conveyors and shaftless spiral conveyors,

　　In terms of appearance,it is divided into two types:U-shaped screw conveyor and tubular screw conveyor.

　　From the perspective of material displacement direction,screw conveyors are divided into two types:horizontal screw conveyors and inclined screw conveyors.

　　This time we will mainly use the example of a shaftless screw conveyor for explanation.
