The Spiral Sand Washer, also known as a screw sand washing machine, is designed for cleaning, classifying, and removing impurities from sand and gravel materials. It is available in single-spiral and double-spiral configurations and can effectively separate soil, clay, mud, and other contaminants from sand. The machine adopts a novel sealing structure, adjustable overflow weir plate, and fully enclosed transmission system to ensure excellent washing, dehydration, and classification performance. It is widely used in highway, hydropower, construction, aggregate, mining, and sand production industries for washing river sand, mountain sand, quarry dust, and manufactured sand used in road construction and concrete production.
The machine has a simple and practical structure with fewer moving parts, ensuring stable operation and easy maintenance.
The rotating spiral blades agitate the material and separate mud, clay, and impurities effectively, improving finished sand cleanliness.
The washer helps retain fine particles during the washing process, supporting better finished sand quality and higher material recovery.
The innovative sealing structure and enclosed transmission system protect key components from water, slurry, and contamination.
The adjustable overflow design allows better water-level control and improves separation accuracy during sand washing.
High-quality steel, wear-resistant components, and an oil-bath drive system support durable performance and lower maintenance cost.
