Working principle: The internal spiral device of the equipment is used to stir the sand and gravel materials, so that the soil and water in the sand and gravel materials are fully mixed and flow out of the equipment. At the same time, the sand and gravel materials gradually separate under the action of the spiral device and are discharged through the top outlet to achieve cleaning and screening. The motor drives the spiral body to rotate at low speed in the water tank through a V-belt, reducer, and gear reducer. The sand and gravel material to be washed enters the water tank through the feeding port, moves forward under the push of the spiral blades, and is washed by water. The water separates the surface of the sand and gravel and the impurities such as soil and stone powder mixed in it. The cleaned sand and gravel are transported from the low end to the high end of the water tank and further washed by the water flow. The clean sand and gravel are discharged from the discharge port, and the sediment and other impurities are discharged through the sewage outlet at the bottom of the water tank.
Structural composition
Spiral blade: It is the core component of the spiral sand washing machine, which rotates to mix, scrub, and lift sand and gravel materials, pushing them to move in the sink.


Industrial equipment Spiral sand washing machine Spiral blade
Sink: Used to hold sand and gravel materials and water, providing a place for the cleaning process. It is usually made of welded steel plates with a certain slope to facilitate the flow of water and materials.

Bracket: Supports the weight of the entire spiral sand washing machine, ensuring the stability of the equipment. It is generally made of steel structure and can withstand the vibration and impact force during equipment operation.
Inlet and outlet device: The inlet is used to feed the sand and gravel material to be washed into the water tank, and the outlet is used to discharge the clean sand and gravel after cleaning.

Device Type
Single spiral sand washing machine: With a relatively simple structure, it is suitable for situations with small processing capacity, small footprint, and low investment cost. It is more suitable for small-scale sand and gravel fields, mines, or construction sites.


Industrial equipment single spiral sand washing machine
Double helix sand washing machine: equipped with two helix bodies working simultaneously, compared to a single helix sand washing machine, it can process more materials per unit time, suitable for situations with high mud content and high production demand. The collaborative work of the two helix bodies allows sand and gravel to be washed more comprehensively and fully in the water tank, resulting in better cleaning effect.

Characteristics and advantages
High cleanliness: The stirring and scrubbing effect of spiral blades can effectively remove impurities such as soil and dust on the surface of sand and gravel, resulting in higher quality and lower mud content of the cleaned sand and gravel, which can meet the needs of high-grade materials.
Low power consumption: The power demand for equipment operation is relatively low, and compared to other sand washing equipment, it has a better energy-saving effect and can reduce production costs.
Stable operation: The sealing structure is good, and the fully enclosed transmission device can effectively prevent water and materials from entering key components such as bearings, reduce equipment wear and failure rates, and extend equipment service life. At the same time, the adjustable weir plate can be adjusted according to different production needs to ensure efficient operation of the equipment.
Large processing capacity: Especially the double helix sand washing machine has strong processing capacity and can meet the production requirements of large-scale sand and gravel production lines.
Less loss of washing materials: During the washing process, it can effectively reduce the loss of sand and gravel materials and improve the recovery rate of materials.
application area 
Construction industry: used in construction sites, concrete mixing plants, etc., to clean construction sand, remove impurities, improve the quality of sand, and ensure the strength and durability of concrete.
Road and bridge construction: Providing high-quality sand and gravel materials for the construction of roads, railways, and other road bridges can help improve the stability and service life of roads.
Mining industry: In mining, ore is washed, graded, and impurities are removed, which can be used for processing various metallic and non-metallic ores to improve their grade and quality.
Water conservancy and hydropower engineering: used for cleaning sand and gravel materials in water conservancy and hydropower engineering, ensuring that the sand and gravel materials used in the project meet relevant standards, and guaranteeing the quality and safety of the project.
