Medium to large tubular conveyor ore powder electric tubular elevator, screw conveyor is suitable for non-viscous dry powder materials and small granular materials.(For example: cement, fly ash, lime, grain, etc.) whileshaftless screw conveyoris suitable for conveying viscous and easily entangledScrew conveyors are divided into two types in terms of conveying form: shaft screw conveyor and shaftless screw conveyor. In terms of appearance, they are divided intoU-type screw conveyor and tubular screwconveyor. Shafted materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating spiral blades push thematerialto move for screw conveyor conveying. The force that prevents the material from rotating with the screw conveyor blades is the weight of the material itself and the frictional resistance of the screw conveyor casing to the material. The spiral blades welded on the rotating shaft of the screw conveyor have different blade surface types according to the material being conveyed, including solid surface type, belt surface type, blade surface type, etc. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to withstand the axial reaction force of the material on the screw. When the machine is long, intermediate hanging bearings should be added.

       When the material is added to the fixed chute, due to the gravity of the material and the friction between the material and the chute, the material accumulated in the lower part of the chute does not rotate with the screw body, but only moves forward under the push of the rotating spiral blades, just like a non-rotating nut moving translationally along a rotating screw, achieving the purpose of conveying materials. This machine is convenient for multi-point loading and unloading, and can simultaneously complete mixing, stirring or cooling functions during the conveying process. It is sensitive to overload and prone to clogging; it has crushing loss to materials. The horizontal screw conveyor has a simple structure, making it easy to install, maintain and handle faults. It is suitable for horizontal or slightly inclined (20obelow) continuous and uniform conveying of loose materials. The working environment temperature is-20—+40℃, and the material temperature is-20—+80℃. Its speed is relatively lower than that of vertical conveyors. It is mainly used for horizontal or small inclination angle material conveying, and the conveying distance is generally not more than70meters.Medium to large tubular conveyor ore powder electric tubular elevator.
