What is a Screw Auger Conveyor?
A Screw Auger Conveyor, often simply called a screw conveyor, is a mechanical device used to move bulk materials in a controlled and efficient manner. It consists of a helical screw blade (also called “flighting”) housed inside a tube or trough. As the screw rotates, materials are pushed forward in a linear direction.
The system is simple, yet highly effective, and can be used in horizontal, inclined, or vertical configurations, depending on the application.
How Does a Screw Auger Conveyor Work?
The working principle of a screw auger conveyor is based on rotational motion and gravity:
- Material Entry:
Bulk materials enter through a feed hopper or inlet point.
- Rotating Screw Blade:
As the helical screw turns, it pushes the material along the length of the conveyor.
- Material Discharge:
The material is then discharged at a designated outlet point.
The rate at which materials are moved can be adjusted by controlling the screw’s rotational speed and pitch.
Key Components
- Trough or Casing –
Encloses the screw and the material.
- Helical Screw (Flighting) –
The rotating component that transports the material.
- Drive Motor –
Provides the necessary torque for rotation.
- Bearings and Shaft Seals –
Reduce friction and prevent leakage.
- Inlet & Outlet Chutes –
Allow easy feeding and discharge of materials.

Benefits of Using a Screw Auger Conveyor
- Precision and Control
Screw auger conveyors provide consistent material flow rates, ensuring precise batching and feeding.
- Space-Efficient Design
They require minimal floor space and can be customized for tight or confined installations.
- Dust-Free Operation
The enclosed design prevents dust from escaping, maintaining a clean and safe working environment.
- Versatility
Can handle dry, semi-solid, and even sticky or abrasive materials across many industries.
- Easy Maintenance
Fewer moving parts mean reduced wear and tear, leading to lower maintenance needs.
- Energy Efficiency
The design minimizes energy consumption while maximizing output.
