Screw Conveyor
A Screw Conveyor is a mechanical device used for transporting bulk materials in a controlled and efficient manner.
It consists of a rotating screw (or helix) inside a trough, tube, or casing, which moves the material along the conveyor’s length.
Screw conveyors are highly versatile and commonly used in industries such as agriculture, mining, food processing, and manufacturing.
This device is widely used in various industries to transport materials efficiently and continuously. It is ideal for moving materials in a variety of forms, including powders, granular substances, and semi-liquid materials.
The screw conveyor consists of a rotating screw (or auger) inside a tube or trough. As the screw turns, the material is pushed along the conveyor, moving from the intake to the discharge end.

Key Features:
- Design:
- The screw’s rotation propels materials forward through the conveyor.
- The casing prevents spillage and protects the materials.
- Material Handling:
- Suitable for granular, powdery, semi-solid, or wet materials.
- Examples include grains, sand, cement, sludge, and food ingredients.
- Types:
- Horizontal Screw Conveyors: Used for short distances or flat surfaces.
- Inclined Screw Conveyors: For moving materials at an angle.
- Vertical Screw Conveyors: For lifting materials to a higher elevation.
- Live Bottom Screw Conveyors: Used to discharge material from storage hoppers or bins.
- Construction Materials:
- Stainless steel for food-grade or corrosive materials.
- Carbon steel for heavy-duty industrial use.
- Applications:
- Agriculture: Grain and seed transport.
- Construction: Cement, sand, and aggregate handling.
- Waste Management: Sludge and waste material movement.
- Food Processing: Handling flour, sugar, and other food materials.
Advantages:
- Simple and robust design.
- Customizable for various applications.
- Effective in handling sticky or abrasive materials.
- Compact and requires minimal space.
Limitations:
Not ideal for handling large, bulky items.
May experience wear when handling abrasive materials.
Limited efficiency for long-distance transportation.
