An Aggregate Washing and Screening Plant is a facility designed to process raw construction materials like sand, gravel, and crushed stone. It removes impurities (clay, dirt, organic residues) and classifies aggregates by size.

Components:

  1. Vibrating Feeder: Uniformly feeds raw material into the plant.

  2. Crushers (Jaw/Impact Crusher): Reduces oversized rocks to manageable sizes.

  3. Screening Equipment (Trommel/Vibrating Screen): Separates aggregates by size.

  4. Washing Systems:

    • Log Washer: Scrubs stubborn clay and contaminants.

    • Sand Screw: Washes and dewaters fine materials.

    • Hydrocyclone: Separates fine particles from sand.

  5. Conveyor Belts: Transports material between stages.

  6. Dewatering Units: Removes excess moisture from washed aggregates.

  7. Storage Silos: Stores processed aggregates.

Workflow:

  1. Feeding: Raw material is fed via vibrating feeder.

  2. Crushing (if required): Oversized rocks are crushed.

  3. Screening: Aggregates are sorted by size using screens.

  4. Washing: Impurities are removed using water and mechanical action.

  5. Dewatering: Moisture is reduced via hydrocyclones or dewatering screens.

  6. Storage: Clean aggregates are stored in silos.

Applications:

  • Concrete and asphalt production

  • Road construction

  • Infrastructure projects

  • Landscaping

Benefits:

  • High-quality aggregate output

  • Environmentally friendly water recycling

  • Reduced waste material
