Spiral Sand Washer
Capacity: 5-300 TPH
Feeding Size: 0.1-10 mm
Discharging Size: 0.1-10 mm
Handling Materials: Natural river sand, sea sand, gravel sand, etc.
Spiral sand washer cleans and classifies sand (0.1–10 mm) by rotating spirals, removing ≤1% clay at 5–300 t/h. Ideal for river/artificial sand washing, it consumes 1–3 m³/t water with optional fine sand recovery. Avoid sticky clay >10 mm.
Advantages

01.
High Cleaning Efficiency
Removes 95%+ clay coatings from 0.1–10mm sand, achieving ≤1% residual impurities for construction-grade material.

02.
Water Conservation
Uses only 1–3 m³ water per ton (vs. 5 m³ in traditional methods) with closed-loop recycling systems.

03.
Dual Functionality
Combines washing and grading in one unit, outputting classified sand (e.g., 0.1–3mm or 1–5mm) directly.

04.
Low Maintenance
Wear-resistant manganese steel spirals last 2–3x longer than standard designs in abrasive silica sand applications.
How Does A Spiral Sand Washer Work
1. Slurry Feeding: Sand-clay mixture (20–30% solids, 0.1–10 mm) enters the inclined trough, where rotating spirals (10–20 RPM) agitate the material.
2. Mechanical Scrubbing: Sand particles collide under spiral motion, dislodging surface clay while counter-current water (0.2–0.4 MPa spray) flushes impurities.
3. Hydraulic Classification: Clean sand rises along the spiral grooves due to density, while clay slurry overflows the weir at the trough’s lower end.
4. Dehydrated Discharge: Washed sand exits the upper chute with <15% moisture (optionally dewatered further via screens), completing the cycle.
