Twisted dragon

The auger is a machine that uses a motor to drive a spiral to rotate and push materials to achieve the purpose of conveying. It can be transported horizontally, inclinedly or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. Screw conveyors are divided into shaft screw conveyors and shaftless screw conveyors in terms of conveying form, and are divided into U-shaped screw conveyors and tubular screw conveyors in appearance. Shaft 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 conveyors with viscous and easy-to-wind materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating screw blade pushes the material to be conveyed by the screw conveyor. The force that prevents the material from rotating with the screw conveyor blade is the weight of the material itself. The friction resistance of the screw conveyor casing to the material. The spiral blades welded on the rotating shaft of the screw conveyor have solid surface, belt surface, blade surface and other types according to the different materials to be conveyed. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the axial reaction force of the screw with the material. When the length of the machine is long, an intermediate suspension bearing should be added.
