Maximize recovery. Minimize costs.
If your foundry uses resin-bonded sand, you know how expensive waste management can get. Our High-Efficiency Sand Reclamation Line is designed to solve exactly that.
Why Modern Foundries Are Investing in Resin Sand Reclamation Systems
In today’s highly competitive foundry industry, manufacturers are facing rising challenges:
- Increasing raw sand costs
- Higher environmental compliance requirements
- Expensive waste sand disposal
- Demand for stable casting quality
- Pressure to reduce production costs
For foundries using furan resin sand, phenolic resin sand, or no-bake sand processes, discarded used sand represents both a major operational cost and an environmental burden.
This is why more foundries are adopting a Foundry Resin Sand Reclamation Line — a highly efficient recycling solution that restores used resin-bonded sand for repeated production use.
A professional resin sand reclamation system can recover 92%–98% of used sand, dramatically reducing new sand consumption while maintaining excellent mold and core performance.
What Is a Foundry Resin Sand Reclamation Line?
Resin Sand Reclamation Line is an automated system designed to recycle used chemically bonded sand by removing residual binder film and impurities from the sand surface.
The process typically includes:
- Crushing
- Magnetic separation
- Mechanical attrition
- Thermal reclamation (optional)
- Dust removal
- Screening
- Cooling
- Sand storage
After processing, reclaimed sand can be reused in mold and core production, significantly lowering operational costs.
Why Resin Sand Recycling Matters
Industry studies show raw silica sand and binder costs can account for a significant percentage of foundry molding expenses.
Without reclamation, foundries face:
❌ High new sand purchasing costs
❌ Large waste disposal expenses
❌ Increased environmental emissions
❌ Inconsistent molding quality
With an efficient reclamation system, foundries gain:
✅ Lower raw material consumption
✅ Reduced waste discharge
✅ Improved process sustainability
✅ More stable molding properties
✅ Faster return on investment
How a Resin Sand Reclamation Line Works
1. Sand Lump Crushing
Used sand lumps are crushed into smaller particles.
This stage ensures efficient downstream separation.
2. Magnetic Separation
Metal particles and ferrous impurities are removed to protect equipment and improve reclaimed sand purity.
3. Mechanical Attrition
High-speed friction between sand particles removes residual resin film from the surface.
This restores:
- Sand roundness
- Surface cleanliness
- Bonding performance
4. Dust Removal & Air Classification
Fine powder and degraded binder residues are extracted through dust collection systems.
This improves reclaimed sand quality.
5. Screening & Cooling
The system ensures:
- Uniform particle size distribution
- Stable temperature
- Consistent molding performance
6. Storage and Reuse
Clean reclaimed sand is stored for immediate reuse in the molding line.
