Type of screw conveyor
There are many kinds of screw conveyors, including U-shaped screw conveyor, pipe screw conveyor, auger conveyor, cement conveyor, pipe fly ash feeder, shaft screw conveyor and double shaft screw conveyor.
Advantages of screw conveyor
Screw conveyor is a kind of machinery that uses the motor to drive the screw to rotate and move materials to achieve the purpose of conveying. Compared with other auger conveyors, it can be transported horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, convenient closed transportation, etc. Screw conveyor can be divided into axial screw conveyor and shaftless screw conveyor in terms of conveying form, and can be divided into U-shaped screw conveyor and tubular screw conveyor in terms of appearance. The shaftless screw conveyor is suitable for non viscous dry powder materials and small particle materials (such as cement, fly ash, lime, grain, etc.), while the shaftless screw conveyor is suitable for the conveyor to be made of viscous and easily entangled materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating screw blades move the materials and carry out the screw conveyor conveying. The force that makes the materials not rotate with the screw conveyor blades is the weight of the materials themselves and the friction resistance of the screw conveyor housing to the materials. The spiral blades welded on the rotating shaft of the screw conveyor have solid surface, belt surface, blade surface, etc. according to the different materials conveyed.
