Spiral Conveyor

A screw conveyor is a device that uses an electric motor to rotate a spiral, pushing materials to achieve the purpose of conveying.MechanicalIt can be horizontally, inclined, or vertically conveyed, featuring simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient for enclosed transportation. The screw conveyor is divided into two types in terms of conveying methods: shafted screw conveyors and shaftless screw conveyors, and into different types in terms of appearance.U-shaped screw conveyorAndPipe auger conveyorThe shafted spiral conveyor is suitable for dry, non-adhesive powdery materials and small particle materials (e.g., cement, fly ash, lime, grain, etc.).Axleless Spiral ConveyorIdeal for conveyors handling sticky and entanglement-prone materials (e.g., sludge, biomass, garbage, etc.). The working principle of the spiral conveyor is rotation.Helical BladeTranslateMaterialThe force that prevents the material from rotating along with the spiral conveyor blades is the weight of the material itself and the frictional resistance from the conveyor housing against the material. The spiral blades welded to the rotating shaft of the spiral conveyor come in various types, such as solid face, belt face, and blade face, depending on the material being conveyed. At the terminal end of the material movement direction, the spiral shaft of the spiral conveyor hasThrust bearingAxial counterforce on the spiral due to material, for longer machine lengths, an intermediate hanger bearing should be added.
