Efficient Sand Washing Machine Construction Sand And Gravel Cleaning

A sand washer is a mechanical device designed to clean and remove impurities (such as dust, clay, and organic matter) from sand, gravel, or crushed stone. It is widely used in construction, mining, and aggregate processing industries to improve the quality of sand for concrete production, road building, and other applications.


Working Principle
Sand washers operate by mixing raw sand with water and then using mechanical agitation to separate impurities. The main processes include:
>Washing: Water is introduced to scrub the sand, dissolving and washing away contaminants.
>Screening: A rotating drum or screw separates finer particles from larger debris.
>Dewatering: Clean sand is discharged, while wastewater and sludge are removed.

Core advantages
✅ Efficient cleaning

Adopting strong stirring + high-pressure water washing, the cleaning rate is as high as 95% or more to ensure the cleanliness of the sand.

With large processing capacity, 50-300 tons of sand can be cleaned per hour to meet the production needs of different scales.

✅ Energy saving and environmental protection

Optimize the water circulation system to reduce water waste. Some models support sewage sedimentation and recycling to reduce environmental pressure.

Low energy consumption design saves more than 50% of costs compared with traditional manual cleaning.

✅ Intelligent grading

Equipped with adjustable screen to accurately control the sand particle size (0-5mm, 5-10mm, etc.) to meet different industry standards.

Some models integrate dehydration function to reduce the water content of sand and facilitate transportation and storage.

✅ Sturdy and durable

The core components (impeller, screen plate) are made of high manganese steel or wear-resistant alloy, which are wear-resistant and have a long service life.

Compact structure, stable operation and low maintenance cost.
