Screw conveyor is divided into shaft screw conveyor and shaftless screw conveyor in
conveying form, and is divided into U-type screw conveyor and tube screw conveyor
in appearance. Shaftless screw conveyor is suitable for non-viscous dry powder materials
and small particle materials (such as cement, fly ash, lime, grain, etc.) while shaftless
screw conveyor is suitable for conveying viscous and easily wound materials. (such as:
sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the
rotating screw blade will push the material and carry out the screw conveyor transport,
so that the material does not rotate with the screw conveyor blade is the material's own
weight and the friction resistance of the screw conveyor shell to the material. The spiral
blade welded on the rotating shaft of the screw conveyor has solid surface type, belt
surface type, blade surface type and other types according to the different conveying
materials. The screw shaft of the screw conveyor has a thrust bearing at the end of the
direction of material movement to react with the axial force of the material to the screw.
When the captain is long, the middle hanging bearing should be added.
