Screw conveyor
Keywords:
The screw conveyor is suitable for horizontal and inclined conveying of granular or powdered materials. Conveying such as vertical conveying. The conveying distance varies depending on the machine model, typically ranging from 2 meters to 70 meters.
The conveying principle of the screw conveyor: Rotating spiral blades push the material forward for screw conveyance.
Structural features: Screw conveyor Spiral blades are welded onto the rotating shaft.
A double-screw conveyor is a type of screw conveyor that features two rotating shafts, each fitted with helical blades. Simply put, it’s created by organically combining two separate screw conveyors into a single unit.
The direction of rotation of the screw conveyor’s rotating shaft determines the conveying direction of the material. However, in general, screw conveyors are designed with rotating blades optimized for unidirectional conveying. When conveying material in the reverse direction, this can significantly reduce efficiency. Conveyor The service life.
Working principle
The rotating helical blades propel the material forward, enabling screw conveyor operation. The force that prevents the material from rotating along with the screw conveyor blades is the combined effect of the material’s own weight and the frictional resistance exerted by the screw conveyor casing on the material. The helical blades welded onto the screw conveyor’s rotating shaft come in various profiles depending on the type of material being conveyed, including solid-faced, belt-faced, and blade-faced designs. At the end of the screw conveyor’s helical shaft, in the direction of material movement, a thrust bearing is installed to accommodate the axial reaction force exerted by the material on the shaft. When the conveyor’s length is relatively long, intermediate support bearings should be added.
