The Cement Silo Screw Conveyor is a robust and efficient mechanical system designed for the seamless transfer of cement or other powdered materials from storage silos to mixing plants, packaging units, or processing equipment.
Featuring a rotating helical screw enclosed in a durable trough or tube, it ensures smooth, controlled, and dust-free material flow with minimal energy consumption.
The cement silo screw conveyor operates on a simple yet highly efficient mechanical principle to transport bulk materials like cement, fly ash, or powdered additives. Here’s how it works:
Material Intake – Cement is fed into the conveyor through an inlet (typically from a silo discharge or hopper).
Helical Screw Rotation – A rotating screw (auger), driven by an electric motor and gearbox, moves axially inside a sealed tube or trough.
Material Displacement – As the screw rotates, its helical flights push the cement forward along the trough, similar to how a corkscrew moves through a cork.
Controlled Discharge – The cement is conveyed smoothly to the discharge point (e.g., a mixer, packing machine, or another silo) with minimal spillage or dust emission.

Inclined Cement Silo Concrete Screw Conveyor construction material selection: when Inclined Cement Silo Concrete Screw Conveyor convey ambient material with corrosive features, carbon steel (Q235) is usually adopted; when screw conveyor conveys high temperature (higher than 150 DEG C), manganese plate is usually adopted since manganese plate has the advantages of high temperature resistance and wear resistance; when the material is corrosive, stainless steel (SS304) is generally adopted because SS304 is corrosion resistant. If screw feeder conveyor conveys food, food grade stainless steel (SS306L) will be adopted.
What's more, after polishing, Inclined Cement Silo Concrete Screw Conveyor has a good appearance, which is commonly used in chemical, pharmaceutical and other industries.
