Heavy-Duty Spiral Sand Washer Screw Sand Washing Machine for Mining and Construction
The spiral sand washer, or screw sand washer is a specialized sand washing machine commonly used in mining, quarrying, and sand production plants. It is designed with an internal spiral mechanism that stirs and agitates sand and gravel, efficiently separating mud, clay, and other impurities to produce clean, high-quality materials.
Your Benefits
Optimized Design
Smart, well-engineered structure ensures smooth operation and easy maintenance.
High Throughput, Low Power Consumption
Handles large material volumes while minimizing power consumption for greater efficiency.
Superior Cleaning & Dewatering Performance
Delivers outstanding washing and dehydration performance, guaranteeing consistently clean, high-quality output.
Robust and Durable
Features a robust, well-sealed structure and fully enclosed transmission system for long-lasting, reliable performance.
Consistent Fine Material Recovery
Effectively retains fine particles, ensuring product consistency and quality.
Working Principle
The spiral sand washer, also known as a screw sand washing machine, operates by using a rotating spiral blade to clean and classify sand. The machine consists of a tank, a spiral screw, a gearbox, and a motor.
When the spiral shaft rotates, the spiral blade stirs the sand and water mixture inside the tank. Impurities such as dust, clay, and silt are removed as the sand is agitated and carried upward by the rotating screw. Cleaned sand is then gradually pushed up to the discharge end of the tank, while dirty water and fine particles overflow from the weir and are discharged through the drainage outlet.
The gentle stirring action and low-speed rotation ensure minimal loss of fine sand and effective cleaning, making it ideal for sand and gravel washing, construction aggregate production, and mineral processing.
Application of Screw Sand Washer
The screw sand washer is widely used for cleaning, grading, and dewatering sand and mineral materials. It is especially effective in removing impurities such as silt, clay, and dust from coarse and fine materials. Common applications include:
Sand and Gravel Plants - Washing and classifying construction-grade sand
Aggregate Processing - Cleaning crushed stone and sand
Mineral Processing - Washing ores and separating fine particles
Concrete & Asphalt Plants - Producing clean sand for concrete mixing
Recycling Facilities - Cleaning and recovering materials from demolition or excavation
Hydropower Stations & Dams - Desilting and cleaning natural sand and stone
Foundries - Washing sand used in casting molds
The spiral sand washing machine is known for its simple structure, high efficiency, and reliability, making it a popular choice for both large-scale industrial operations and medium-sized construction material plants.
