Working Principle
An auger screw conveyor (also known as a screw conveyor) is a mechanical device used to transport materials, often in bulk. It consists of a helical screw blade (called a flighting) that rotates inside a tube or trough, moving materials along its length. Here's a breakdown of its working principle:
Working Principle:
-
Material Entry:
- Material is fed into the conveyor system, usually through a hopper or inlet at one end of the conveyor.
-
Rotating Screw Mechanism:
- The rotating helical screw inside the conveyor rotates when the motor is activated. The screw can have varying designs (continuous, ribbon, paddle) depending on the application.
-
Material Transport:
- As the screw rotates, the material moves forward due to the rotational force of the screw and the friction between the material and the conveyor wall.
- The spiral motion pushes the material from the inlet toward the discharge point.
-
Discharge:
- The material is transported along the conveyor length until it reaches the discharge outlet, where it exits the system.
Factors Influencing the Operation:
- Screw Pitch: The distance between successive threads or coils of the screw affects the rate of material flow. A larger pitch results in faster transport.
- Speed of Rotation: The faster the screw rotates, the faster the material is moved.
- Material Properties: The flow characteristics of the material being transported, such as moisture content, particle size, and cohesiveness, will affect how efficiently the screw conveyor works.
- Inclination Angle: Screw conveyors can operate horizontally or at an incline. The angle of inclination affects the conveyor's efficiency, with steeper angles generally reducing capacity.

- Versatility: Can handle a wide range of materials, from grains to powders to sludge.
- Enclosed System: Reduces dust and contamination.
- Customizable: Can be adapted to various lengths, sizes, and inclinations to suit specific applications.
Combined and designed for unpacking, unloading, and transporting powdered, granular, and small ton bags. It's extensively used across various industries including petrochemicals, raw materials, plastics, carbon black, mining, and food additives. Additionally, it is highly valued in the cement industry for its simple structure, low production cost, user-friendly operation, excellent cost-effectiveness, and built-in dust collector to prevent dust dispersion.
