Can Sea Sand Be Used for Reclamation?

Sea sand can be used for reclamation, but it requires thorough processing due to high salinity, organic content, and fine particle size. A specialized crushing and screening生产线 is essential to transform raw sea sand into usable construction-grade aggregates.

Crushing and Sand-Making Production Line

A typical sea sand processing line includes:
1. Washing System: Removes salt and impurities (e.g., wheel bucket sand washer with 50–100t/h capacity).
2. Primary Crushing: Jaw crusher (e.g., PE600×900, feed size ≤500mm, output 50–160t/h).
3. Secondary Crushing: Cone crusher (e.g., HPT300, max. feed size ≤240mm, output 100–350t/h).
4. Sand Making: VSI crusher (e.g., B-9100, output 60–520t/h) for shaping fine particles.
5. Screening: Multi-layer vibrating screen (e.g., 3YK3070, processing capacity 50–800t/h).

Suitability of Processed Sea Sand Aggregates

After washing and grading:
– Fine modulus: 2.6–3.0 (符合ASTM C33标准).
– Chloride content: <0.01% post-treatment.
– Applications: Land reclamation, concrete mixing (non
