A beach sand screening plant is an industrial system designed to clean raw sand extracted from beaches or riverbeds by removing impurities (stones, gravel, shells, roots) and producing homogeneous sand. These plants play a critical role in maintaining tourist beaches, construction projects, or environmental restoration.

2. How Does It Work?

  1. Feeding: Raw sand is loaded into the hopper via an excavator or conveyor belt.

  2. Pre-Screening (Trommel Screen): Large debris (stones, branches) is removed using a rotating trommel screen.

  3. Fine Screening (Vibrating Screen): Sand is passed through vibrating screens to classify it by grain size (e.g., 0-5 mm).

  4. Washing (Optional): Some plants include a washing unit to remove salt, clay, or organic residues.

  5. Stockpiling and Transport: Cleaned sand is transferred to stockpiles or directly to the site of use.

3. Purpose

  • Beach Maintenance: Restores beaches damaged by wave or wind erosion.

  • Safety: Removes sharp shells, glass, or stones to make beaches safe for public use.

  • Construction Quality: Ensures sand used in construction is uniform and pure.

4. Applications

  • Tourism: Maintenance of hotel and public beaches.

  • Post-Storm Cleanup: Replenishes sand after severe weather events.

  • Construction Projects: Produces high-quality sand for concrete or plaster.

  • Ecological Restoration: Protects natural habitats (e.g., sea turtle nesting areas).

5. Advantages

  • High Efficiency: Processing capacity of 50-500 tons per hour.

  • Mobility: Some models are portable with wheeled or tracked chassis.

  • Eco-Friendly: Preserves marine ecosystems by recycling natural sand.
