What Is Spiral Sand Washing Machine Used For?

Spiral Sand Washing Machine is mainly used in sand production line, it is the “scavenger” in the sand production line, which is mainly used to remove soil, dust and other impurities in sand and gravel. Spiral sand washer has strong crushing and dispersing ability to the fine mud clusters, and the sand and gravel are cleaner after cleaning.

Spiral Sand Washing Machine is a kind of sand washing machine, mainly through the spiral device in the equipment to mix the sand and gravel material, so as to make the soil in the sand and gravel material mixed with water, and discharged from the flow port on the equipment, while the sand and gravel material is gradually screened under the action of the spiral device, and discharged from the discharge port on the top, so as to realize the cleaning and screening effect of the sand and gravel material.

Spiral Sand Washing Machine is suitable for metallurgy, building materials, hydropower and other industries, such as washing, grading, removing impurities and other operations, sand and gravel aggregates in the fine and coarse grain size material cleaning.

Working Principle of Spiral Sand Washing Machine

Spiral Sand Washing Machine is generally tilted when it is installed, when it works, the spiral begins to rotate under the action of the motor, the material is fed evenly from the feed box, and a certain amount of water is continuously injected into the main tank, the transmission department drives the spiral shaft to rotate at a certain speed, forcing the material to turn over and roll in the tank and move towards the discharge port, the fine-grained material and impurities are discharged along with the overflow water through the overflow weir, and coarse-grained material is discharged by the discharge port, thus realizing the material washing, grading, removing impurities and dewatering. Thus realizing the washing, grading, removing impurities and dewatering of materials, and completing the cleaning of sand and gravel.

Advantageous features of Spiral Sand Washing Machine

• High cleanliness: the sand and gravel cleaned by the spiral sand washer, especially the fine sand is cleaner than the wheel bucket sand washer, but its efficiency is relatively low, the materials cleaned by the spiral sand washer can meet the requirements of high-grade materials.
• Low failure rate, long life: the rotating part of the spiral sand washer is isolated from water and sand, so its wear and failure rate is greatly reduced, and the service life becomes longer, which saves the secondary input cost of the spiral sand washer in the process of using.
• Simple structure: the sand washer has a simple structure, stable operation, and it is convenient for overhaul and maintenance.
• Sewage can be recycled: the sewage after washing the sand through the sedimentation tank and for re-use, saving resources and reducing investment costs.

Spiral Sand Washing Machine FAQ

Q: How much water does a spiral sand washer use per ton of sand?

A: A spiral sand washing machine typically uses 10-30 tons of water per 100 tons of sand. The exact amount depends on the sand’s clay content and your required cleanliness. You can reduce water consumption by 80-90% by adding a thickener and water recycling system.

2. Q: What is the maximum feeding size for a spiral sand washer?

A: Most spiral sand washers can handle sand particles up to 10mm. If your material contains larger stones or gravel (over 10mm), we recommend installing a vibrating screen before the washer to remove oversize material and prevent damage to the spiral blades.

3. Q: How do I prevent the spiral blades from wearing out too quickly?

A: To extend blade life: ① Feed a consistent, even amount – avoid overloading; ② Remove large debris (over 10mm) before washing; ③ Choose wear-resistant materials – we offer blades made of polyurethane or high-chromium alloy, which last 2-3x longer than ordinary steel.

4. Q: Can a spiral sand washer remove clay from dirty sand?

A: Yes. The machine uses a counter-current washing tank and rotating spiral to scrub and separate clay, silt, and impurities from sand particles. For heavy clay contamination, we recommend adding a log washer before the spiral sand washer for better cleaning results.

5. Q: What is the capacity range of your spiral sand washers?

A: Our spiral sand washers are available in capacities from 50 to 350 tons per hour (TPH). Popular models include: single-spindle (50-150 TPH) and double-spindle (150-350 TPH). Tell us your target output and feed material, and we’ll recommend the right model within 24 hours.
