Double Screw Washing Machine Silica Sand Washer Spiral Sand Washer

Product Description

Double Screw Washing Machine Silica Sand Washer Spiral Sand Washer

Spiral washing machine is widely used for washing all kinds of easy-washing and difficult-to-wash ore. If the ore contains more than 20% mud, it will block the crusher and the chute. The spiral washing machine can make the ore with more than 20% mud be stirred and scrubbed in the washing machine to achieve the purpose of separating the ore from the mud. The washed ore is discharged from the discharge port, and the muddy water is discharged from the tailing end. The equipment is matched with the trommel scrubber washing machine, and it is currently a relatively effective washing equipment for processing difficult-to-wash ore.

Working Principle and Parameters

Spiral washing machine removes clays and other deleterious materials by material-on-material inter-particle scrubbing, as well as the interaction with the paddle shafts and water. For clay contaminated hard rock and ore, it needs more aggressive washing action than any other type of ore available. The left and right spiral shafts complete ore scrubbing and lifting, also convey the material over the machine length to the discharge.

Product Hotselling Point

1.High cleanliness and excellent washing performance: The spiral sand washer utilises water buoyancy and the density difference between solid particles for classification. Through continuous agitation by spiral blades, sand and gravel are thoroughly separated from slurry. It is suitable for cleaning highly viscous, high-clay-content materials such as river sand and manufactured sand.

2.Combining three key functions: washing, dewatering, and grading Washing: Removes soil, dust, and impurities from the surface of sand and gravel; Dewatering: Reduces the moisture content of discharged sand through inclined positioning and centrifugal action; Grading: Automatically sorts particles by size to meet diverse grain size requirements. This integrated design reduces the need for ancillary equipment, enhancing the efficiency of the entire production line.

3.Rational structure, stable and reliable operation: Features a fully enclosed transmission mechanism and waterproof sealed bearings, effectively preventing mud and water ingress to extend core component lifespan; The spiral shaft is constructed from high-strength materials, with blades available in polyurethane or manganese steel alloy for enhanced wear and corrosion resistance.

4.Wide applicability with bespoke service options: The spiral sand washer is suitable for processing materials within the 0 to10mm particle size range, such as construction sand cleaning; aggregate preparation for hydraulic and hydroelectric projects; and pre-concentration desliming operations for metallic minerals including gold and iron ores. It accommodates both single-spiral and dual-spiral configurations, enabling non-standard customisation according to output requirements and site conditions

1.What is the main purpose of a twin-screw sand washer?
It is mainly used for washing and classifying sand materials, removing clay and impurities to improve sand purity.

2.What is the difference between a double-screw and a single-screw sand washer?
Double-screw models have higher capacity and more uniform washing, suitable for higher production lines.

3.Can it wash kaolin or materials with high clay content?

Yes, but for sticky materials, pre-treatment with a scrubber or blunger is recommended for better results.

4.How much water does it consume?
Depending on model and clay content, typical consumption is 2–5 tons per ton of sand. A water recycling system can reduce make-up water.

5. What are the wear parts?

Main wear parts are screw blades, liners, bearings, and seals.

6. Can it be combined with other equipment?
Yes, it is often combined with vibrating screens, sand washing & recycling units, filter presses, etc., to form a complete sand washing line.
