Durable Spiral Sand Washer / XL Screw Washing Machine for River & Artificial Sand

High Washing Cleanliness: Through spiral stirring and mutual grinding of sand and gravel, effectively removes mud, dust, and impurities from sand surface, ensuring high-purity finished sand.

Excellent Dewatering Effect: Novel sealing structure combined with adjustable overflow weir plate ensures superior dewatering performance for clean, dry finished sand.

Effective Classification & Impurity Removal: Utilizes different settling velocities of particles by size and density to achieve accurate classification and thorough impurity removal.

Minimal Sand Loss: Fine sand loss is extremely low during washing; washed sand grading and fineness modulus meet national standards.

Novel Sealing Structure + Fully Enclosed Oil-Bath Transmission: Innovative sealing design with fully enclosed oil-bath transmission ensures long-term maintenance-free operation.

Bearing Isolated from Water & Materials: Bearings are completely separated from water and sand to prevent rusting and damage, significantly extending service life.

Reasonable Structural Design: Simple yet robust construction ensures stable and reliable operation with minimal downtime.

Single & Double Spiral Options: Available in single spiral and double spiral models to meet different capacity requirements.

Durable & Wear-Resistant Construction: Built with high-quality materials for excellent wear resistance and long service life.

Large Processing Capacity: Single machine capacity reaches 20-350 tons per hour, suitable for various production scales.
