Screw Conveyor

Screw conveyors are divided into two types: shaft screw conveyors and shaftless screw conveyors. They are divided into U-shaped screw conveyors and tube screw conveyors. Axle screw conveyors are suitable for non-adhesive dry powder materials and small particle materials (eg cement, fly ash, lime, grain, etc.) and shaftless screw conveyors suitable for conveyors made of viscous and easily-wound materials. (Such as: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating spiral vane transfers the material and conveys it through the screw conveyor. The force that the material does not rotate with the screw conveyor blade is the weight of the material itself. The friction resistance of the screw conveyor casing to the material. Spiral blades welded on the rotating shaft of the screw conveyor. The surface shape of the blade has different types such as solid surface type, belt type surface, and blade surface type according to the material to be conveyed. Spiral conveyor screw axis in the direction of material movement in the end of the thrust bearing with the material to the spiral of the axial reaction force, in the captain is longer, should be added to the middle of the hanging bearings.
