A spiral sand washer, also called a spiral classifier, can be used as a sand washer and for mineral processing and classification. In sand and gravel plants, wheel-type sand washers are more common. While spiral sand washers are not as widely used, they have many significant advantages, which we will explore below.

　　What are the advantages of a spiral sand washer?

　　1. Spiral sand washers have a large overall size and high processing capacity, and are available in single-spiral and double-spiral configurations.

　　2. Compared to wheel-type sand washers, spiral sand washers have a long washing cycle and higher washing efficiency.

　　3. Spiral sand washers utilize the difference in sand particle size and specific gravity to wash sand, classifying coarse and fine sand simultaneously while minimizing sand loss.

　　4. Spiral sand washers rely on spiral blades for washing, which are more wear-resistant than screens, reducing the frequency of replacement of vulnerable parts and extending the equipment's lifespan.
