The spiral sand washer is the cleanest among the sand washing machine types, yet it's not commonly seen. Conversely, the wheel sand washer is more prevalent. This is because, although the spiral sand washer cleans sand effectively, its low sand washing capacity and high price make its overall cost-performance low. The wheel sand washer, on the other hand, offers higher sand washing capacity and lower price, making it more cost-effective. Additionally, the sand washing effect of both machines in general working conditions is not significantly different. When paired with fine sand recovery machines, the wheel sand washer is superior to the spiral sand washer in all aspects except for sand washing. However, for complex sand washing environments, we still recommend using the spiral sand washer, especially when sand contains a high amount of clay or when mixed with gravel. In such cases, the processing capacity of the spiral sand washer is enhanced! The price for a 100-ton capacity spiral sand washer is over 40,000 yuan, and for a 200-ton capacity model, it's a double-spiral design, priced over 100,000 yuan! The price also depends on the length of the spiral sand washer, with standard designs at 7, 8, and 10 meters, so price comparison alone is not sufficient! Welcome to call for inquiries!
