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.

Bucket Washing Machine
The bucket type sand washing machine is evolved from the sand picking bucket bucket device, which has the characteristics of low cost, high sand lifting height, good water control effect, and the processing capacity can be adjusted according to the size of the hopper, and the power consumption is small. The sand washing machine can solve the problem of high sand loss rate.
The bucket type sand washing machine has the advantages of reasonable structure, convenient maintenance, large processing capacity, small power consumption, high washing degree and less loss of fine sand. The equipment is widely used in construction sites, sand and gravel plants, railway construction, highway construction, viaduct construction, concrete mixing stations, hydropower station concrete dam sites and other industries with high sand quality requirements.

Spiral washing machine
Spiral sand washing machine (also known as auger sand washing machine) is divided into double spiral stone washing machine and single spiral stone washing machine. It is mainly used to remove impurities (such as dust) from sand products. Because it is mostly washed with water, it is called a stone washing machine. Among them, the stone here refers more to sand, so it is also called a sand washing machine.
The spiral sand washing machine has a simple structure and stable performance. The impeller drive bearing device adopts a special sealing device to isolate it from water and water-receiving materials, which greatly avoids the phenomenon of bearing damage caused by water immersion, sand and pollutants.

Wheel washing machine
Wheel sand washing machine is a new type of sand washing machine, which is more energy-saving, environmentally friendly, economical and durable than traditional sand washing machines. Wheel sand washing machine is a kind of water-washing sand washing equipment suitable for sand making machine. Bucket sand washing machine can wash away trace stone powder and impurities from the mixed sand produced by the sand making machine, thereby improving the quality of sand.

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.
