Description: An auger, formally known as a screw conveyor and commonly called a screw conveyor or auger conveyor, is a type of continuous conveying machinery without flexible traction components. Its core working principle is based on Archimedes' screw principle: a motor drives a shaft fitted with helical blades to rotate inside a closed trough or pipe through a reducer, and the axial thrust of the blades pushes the material forward along the trough, achieving continuous conveying in horizontal, inclined, or vertical directions.
Structural componentshelical blades, screw shaft, trough/pipe body, drive unit, bearing assembly, and inlet and outlet.
Main categoriesClassified by the presence or absence of a central shaft:. Shafted screw conveyor: for non-sticky dry powder and small granular materials, such as cement, fly ash, lime, grain, and flour.
Shaftless screw conveyor (WLS type): The central shaft is removed and the blades are driven from the ends. It is for conveying viscous and easily entangled materials such as sludge, domestic waste, biomass, and long fibers.
Classified by external structure:. U-shaped screw conveyor (trough type): Open trough body easy to inspect and observe.
For horizontal or slightly inclined conveying. Tubular screw conveyor: Fully enclosed circular tube structure with excellent sealing.
Stop dust leakage and capable of large-angle or even vertical conveying. Classified by conveying direction:horizontal, inclined, and vertical.has and.
Sealed and environmentally friendly: The fully enclosed tubular or U-shaped covered design greatly reduces leakage when conveying dusty materials.
Meeting environmental protection requirements.
Flexible layout: It can be used for horizontal, inclined (≤15°), and vertical conveying; multiple inlet and outlet ports can be arranged.
And it supports reverse conveying. It can be directly connected and fixed to supporting equipment without the need for a foundation.
High conveying efficiency: The small diameter, high speed, and variable pitch design ensures smooth, fast, and uniform feeding.
Multifunctional: It can simultaneously processes such as stirring, mixing, cooling, loosening, and heating during conveying.
Easy maintenance: The U-shaped head and tail bearings are externally mounted and the hanger bearings are with oil cups for centralized lubrication.
A cleaning device is installed at the discharge end, and the overall noise level is low.
Material options: Carbon steel stainless steel (304/316) manganese steel and plastic for different working conditions such as food processing.
Chemical processing and corrosive environments.
