Learn about fine sand recovery systems? They can help reduce your losses!

With intensified environmental regulations, industries across the board are prioritizing “environmental protection” in their operations. Sand and gravel aggregate production is no exception. In a well-designed and eco-friendly sand production line, installing dust collectors and water-washed sand washers is essential. However, the wastewater from wet sand washing inevitably contains excessively fine sand and surface sand that escapes with the water flow. Each production line typically loses 5%-25% of its material, and the annual loss, when calculated precisely, is staggering. Recovering this lost material could yield substantial profits. Let's first understand how sand washers operate to see how sand loss occurs.

Sand washers are categorized into bucket wheel washers and spiral washers. Bucket wheel washers are widely used in mining, construction materials, chemical processing, transportation, and concrete mixing plants for material washing and sorting. The washing process involves circular motion. Spiral sand washing equipment utilizes the propulsive action of spiral blades to clean soil. Compared to bucket wheel washers, spiral washers achieve higher cleanliness and better cleaning results for aggregates. Similarly, by leveraging the differing specific gravities of sand, silt, and water, sand is extracted while water and silt flow away through chutes. Although modern machinery technology is relatively mature, some sand and gravel loss is unavoidable in actual production. Today, we introduce a sand washing and recovery device to help minimize these losses.

The X Series Fine Sand Recovery System, developed by OCP Heavy Industry by integrating domestic and international technologies with practical applications, represents world-class advanced technology. Widely used in wet-process aggregate production systems, it recovers fine sand particles (under 0.16mm) carried away by wash water, thereby reducing fine sand loss. The collected fine sand can be blended into finished sand as needed, ensuring optimal gradation, The fineness modulus meets specifications, enhancing sand quality and economic efficiency while reducing fine sand discharge and preventing secondary environmental damage.

The X Series Fine Sand Recovery System primarily consists of a motor, slurry pump, hydrocyclone, linear vibrating screen, washing tank, and return hopper.

Product Features:

1. Minimizes loss of fine sand and stone powder while enabling effective recovery, compensating for uncontrollable losses in conventional sand washing equipment.

2. Vibrating screen utilizes polyurethane mesh, offering longer service life and reduced clogging compared to other screen types.

3. The hydrocyclone is lined with polyurethane for enhanced wear resistance and extended service life, facilitating efficient slurry concentration and liquid clarification.

4. Achieves high recovery efficiency with low operating costs, capable of recovering up to 85% of fine particles from total discharge.

5. Ensures thorough recovery of fine particles, reducing the frequency of sedimentation tank cleaning.
