Spiral Sand Washer

Spiral sand washing machines are divided into single spiral and double spiral types, and are mainly used for washing, grading, impurity removal, and washing of fine and coarse grained materials in sand and gravel fields, highways, hydropower, construction and other industries. They have the characteristics of low power consumption and high cleaning degree. The good sealing structure ensures the high efficiency and durability of the equipment, good cleaning and dehydration effects, and stable fine grain products.

Product introduction
CATHAY spiral sand washing machine is specially designed for cleaning sand and gravel aggregates and mine tailings. It uses double spiral strong rolling technology to achieve efficient cleaning. The mud content of finished sand is ≤0.8% (national standard ≤3%), the fine sand recovery rate is ≥95%, and the single machine processing capacity is 50-500 tons/hour.

Core advantages
✅ 99% cleaning rate
- Extended spiral trough (≥6 meters), mud and sand are fully separated
- Adjustable inclination design (15°-25°), adaptable to different mud contents
✅ Zero loss of fine sand
- Optional cyclone + dewatering screen recovery system
- Recovery rate of fine sand above 0.075mm ≥95%
✅ Water-saving and durable
- Water consumption is only 1.8m³/ton of sand (3-5m³ for traditional equipment)
- Blade lining wear-resistant alloy steel, life of 20,000 hours
✅ Intelligent operation and maintenance
- Automatic protection against current overload
- Bearing seals to prevent sand, free replacement for 3 years
