How to Solve the Problem of Manufactured Sand Loss in Production

Key Causes of Fine Sand Loss

1. Excessive Fine Sand Content

An overly high proportion of fine sand in raw materials can significantly reduce the efficiency of fine sand recovery equipment. Excessive fines may clog the screens, lower recovery rates, and hinder equipment performance.

2. Inappropriate Selection of Fine Sand Recovery Equipment

The market offers various types of fine sand recovery machines, each with different specifications and performance. Selecting unsuitable equipment can lead to poor recovery results. It's crucial to choose machines tailored to your raw material properties and production scale. Typically, screen apertures should be around 200 mesh, with properly adjusted vibration frequencies.

3. Improper Moisture Control

While higher moisture levels may make the final sand cleaner, they can also lead to severe washing away of fine particles. Excessive water flow accelerates the loss of usable sand and gravel. Moisture levels must be carefully regulated to balance cleanliness and material retention.

Practical Measures to Minimize Manufactured Sand Loss

Source Control

Choose raw materials with appropriate fine sand content. During production, regulate powder size and screen aperture to reduce excessive fines from the beginning.

Proper Equipment Selection

Invest in fine sand recovery equipment that matches your material characteristics and processing needs. Avoid over-sized or underperforming machines that increase waste and reduce recovery efficiency.

Use Sedimentation Tanks for Secondary Recovery

If feasible, direct the wastewater into sedimentation tanks to allow fine particles to settle. These particles can then be recovered in a secondary process, increasing overall material yield.

Control Water Usage

Adjust water flow to optimize cleaning efficiency while preventing unnecessary loss of fines. Smart water control reduces waste, improves productivity, and supports environmental sustainability.

Conclusion

Addressing manufactured sand loss requires a combination of proper material selection, optimized equipment, and controlled processing parameters. By implementing the above strategies, sand production lines can reduce waste, improve efficiency, and recover more valuable resources.
