High-Efficiency Sand Screw Washer Case Study: Dual Assurance for Quality and Profitability

In a large-scale manufactured sand production project, the client faced challenges with high silt content and uncontrolled stone powder levels in the finished sand, resulting in substandard product quality and weak market competitiveness. To address this critical issue, the project team introduced an advanced Sand Screw Washer.

Upon commissioning, the equipment delivered immediate results, demonstrating its advantages in three key areas:

The Sand Screw Washer employs inclined spiral blades to continuously agitate and tumble the sand. Under water flushing, it effectively strips and removes soil and impurities adhering to the sand particles' surfaces. The treated finished sand maintains a stable clay content below 3%, meeting national high-standard construction sand requirements and significantly enhancing product value.

Compared to traditional sand washing equipment, this machine features a unique overflow weir design. Through precise water flow control, it effectively minimizes the loss of beneficial fine sand particles larger than 0.16mm. This not only stabilizes the sand gradation but also directly increases the overall sand yield, delivering substantial economic benefits to customers.

The equipment features a rational structural design with wear-resistant core components, resulting in extremely low failure rates that ensure continuous and stable production line operation. Additionally, routine maintenance is straightforward, reducing long-term operational and labor costs.

In summary, this Sand Screw Washer has successfully addressed core challenges for customers through its exceptional cleaning performance, high material recovery rate, and reliable operational capabilities. It has become a key piece of equipment for enhancing aggregate quality and project profitability.
