Cement and aggregates screw conveyors are essential equipment in material handling for industries like cement production, concrete batching, mining, and construction. These conveyors transport bulk materials such as cement, sand, gravel, and other aggregates efficiently over short to medium distances.

Key Features of Cement and Aggregates Screw Conveyors:

1. Material Handling Efficiency:
   • Designed to move bulk materials continuously with minimal spillage.
   • Handles powders (cement, fly ash) and granular materials (sand, gravel, crushed stone).
2. Construction & Design:
   • Helical Screw: A rotating screw blade (flight) inside a U-shaped or tubular casing.
   • Materials: Typically made of wear-resistant steel, stainless steel, or carbon steel.
   • Configurations: Horizontal, inclined, or vertical screw conveyors based on application needs.
3. Capacity & Customization:
   • Available in various diameters (100mm to 600mm or more) and lengths.
   • Can be customized with variable pitch, multiple inlet/outlet points, and different screw flight designs.
4. Dust Control & Sealing:
   • For cement handling, enclosed conveyors prevent dust emissions and material loss.
   • Equipped with wear liners and anti-clogging mechanisms.
5. Drive Mechanism:
   • Powered by electric motors with gear reducers for efficient torque transmission.
   • Speed control using VFDs (Variable Frequency Drives) for precise material flow.

Applications:

• Cement Industry: Feeding cement from silos to mixers or packing systems.
• Concrete Batching Plants: Transporting cement, sand, and aggregates to mixing units.
• Mining & Quarrying: Moving crushed stone, gravel, and minerals.
• Waste-to-Energy Plants: Handling fly ash and bottom ash (like in your field of expertise).

Advantages:

✔️ Compact design for space-saving installation.
✔️ Low maintenance with minimal moving parts.
✔️ Handles abrasive materials effectively.
✔️ Can operate in harsh environments with proper liners and coatings.
