The complete fine sand recovery machine set consists mainly of a vibration motor, vacuum high-pressure pump, high-pressure separator, dewatering screen, cleaning tank, and return material box, etc.
The fine sand recovery pump transports the sand-water mixture to a high-pressure separator. The finely divided sand, concentrated by centrifugal classification, is supplied to a vibrating screen through a sedimentation spout. After dehydration by the vibrating screen, the fine sand is effectively separated from water. A small amount of fine sand is recycled back to the cleaning tank via a return bin. When the liquid level in the cleaning tank is too high, excess fluid is discharged through the discharge outlet. The linear vibrating screen recovers material with a weight concentration of 70%-85%. Adjusting the fineness modulus can be achieved by changing the pump speed, altering the mortar consistency, adjusting the overflow water volume, or replacing the sand outlet.
Fine Sand Recovery Machine Introduction
The existing artificial sand production lines predominantly use the wet process. Regardless of the type of fine sand crushing machine employed, a significant drawback is the severe loss of fine sand (particles larger than 0.5mm), with some losses exceeding 20%. This not only results in significant losses but also severely affects the sand gradation, leading to unreasonable gradation, coarse fineness modulus, and greatly reducing the quality of the manufactured sand products. Excessive fine sand discharge can also cause environmental pollution and increase the costs for cleaning sedimentation ponds.
To address the aforementioned issues, our company has successfully developed a fine sand recovery system. This system, a state-of-the-art fine material extraction device, is a product of our in-house technology and is designed to cater to the actual conditions of sand powder. It is widely used in hydropower plant aggregates processing systems, glass raw material processing systems, artificial sand production lines, coal preparation plant coarse slime recovery, and engineering (slurry purification) applications. It effectively resolves the issue of fine sand loss while also tackling the problem of insufficient commercial concrete parent sand for C50/C75 mixtures at concrete batching stations.

Fine Sand Recovery Machine Performance Features
1. In the traditional wet processing of artificial sand by manual methods, the spiral sand washing machine and impact crusher are used for washing mud and dewatering, resulting in almost uncontrollable loss of fine sand in the artificial sand. The adoption of this fine sand recovery system can effectively reduce the loss of fine sand, and effectively addresses the problem of high fineness modulus and low content of fine sand in the finished product of artificial aggregate processing system.
2. The vibration screen features polyurethane mesh, which has a longer lifespan than other types of screens and doesn't clog. It effectively addresses the issue of fine sand loss while also solving the problem of insufficient mother sand for C50/C75 commercial concrete at mixing stations.
3. The inner lining of the high-pressure separator is made of polyurethane, which enhances the overall lifespan of the unit and ensures smooth operations for tasks such as slurry concentration and liquid clarification.
4. Recovers 85% of fine particulate matter from total recyclable emissions, boasting unparalleled technological and economic advantages compared to other fine sand recovery equipment.
5. Fine sand is fully recycled, reducing the workload of the sedimentation pond and lowering the cleaning costs for the pond.
6. Reduced material stacking time for direct shipment and market supply.
7. Solutions can be tailored to meet various user requirements.
