Screw Conveyor

Product Description

The screw conveyor is a kind of machine which uses the motor to drive the screw to rotate and push the material to realize the purpose of conveying. It can be transported horizontally, obliquely or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance and easy closed transportation. The screw conveyor is divided into two kinds of conveying forms: the axle screw conveyor and the axle-less screw conveyor, and the shape of the screw conveyor is divided into U-type screw conveyor and tubular screw conveyor. Axis screw conveyor is suitable for non-sticky dry powder materials and small particulate matter. (e.g. cement, fly ash, lime, grain, etc.) Axis screw conveyor is suitable for conveyor from sticky and easily winding materials. (e.g. sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating screw blade pushes the material to the screw conveyor, so that the force that the material does not rotate with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor shell to the material. The helical blades welded on the rotating shaft of the screw conveyor have solid surface, belt surface and blade surface according to the different materials conveyed. The screw shaft of screw conveyor has thrust bearing at the end of the material movement direction to give the axial reaction force to the screw along with the material. When the length is long, the bearing should be suspended in the middle.
