Comprehensive Guide to Spiral Sand Washers: Principles, Advantages, and Pricing

Spiral Sand Washing Machine, also known as spiral stone washing machine, is an indispensable washing and processing equipment in the sand and gravel aggregate production line. This equipment is widely used in construction sites, sand and gravel plants, glass factories, and concrete precast plants of hydropower stations for washing, grading, and impurity removal of materials. It features a solid structure, stable operation, high cleanliness, and energy saving. During long-term operation, its spiral blades are made of wear-resistant materials, which greatly extends the service life, making it an ideal sand washing equipment for complex working conditions.

Working Principle of Spiral Sand Washing Machine:
During operation, the motor drives the impeller to rotate slowly after decelerating through the V-belt, reducer, and gear. The sand and gravel enter the washing tank through the feeding trough, roll under the driving of the spiral blades, and grind against each other to remove the impurities covering the surface of the sand and gravel. At the same time, the vapor layer wrapping the sand particles is destroyed to facilitate dehydration. During this process, water is continuously added to form a strong water flow, which takes away impurities and foreign matters with small specific gravity in time and discharges them from the overflow port to complete the cleaning process. The clean sand and gravel are taken away by the blades, and finally poured into the discharge trough from the rotating impeller to complete the entire washing process.

Application Advantages of Spiral Sand Washing Machine:

Strong processing capacity: The processing capacity of the spiral sand washing machine is usually between 20-300t/h, which can meet production needs of different scales, especially suitable for processing ores with high mud content.
Excellent wear resistance: The core spiral blades are made of special wear-resistant steel plates, which are sturdy and durable, greatly reducing the cost of daily wear and part replacement.
Extremely high cleanliness: Through long-distance spiral rolling and physical friction, the materials are cleaned very thoroughly, significantly enhancing the commercial value of the finished products.
Stable and reliable operation: The scientific structural design ensures smooth operation with minimal noise. The sealing system effectively prevents water and mud from entering the bearings, reducing the failure rate.
