Spiral Sand Washer

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.
