The spiral sand washing machine is one of the cleanest in the sand washing machine category, yet it is not commonly seen. Conversely, the water wheel sand washing machine is more prevalent. This is because, although the spiral sand washing machine provides clean sand, it has a low sand washing capacity and high price, making its overall cost-performance ratio low. In contrast, the wheel-type sand washing machine offers a higher sand washing volume and lower price, resulting in a higher cost-performance ratio. Moreover, both machines have a negligible difference in sand washing effectiveness under typical working conditions. When paired with a fine sand recycling machine, the wheel-type sand washing machine outperforms the spiral sand washing machine in all aspects except for sand washing quality. However, for complex sand washing environments, such as sand containing high amounts of clay or mixed sand and stone, the spiral sand washing machine is still our recommended choice. Its processing capacity is magnified in such cases! The spiral sand washing machine with a 100-ton processing capacity costs over 40,000, while the 200-ton model is a dual-spiral design, priced over 100,000! The price also depends on the length of the spiral sand washing machine, with standard designs being 7 meters, 8 meters, and 10 meters long, so price comparison alone is not sufficient.
