Addressing Critical Needs in Foundry Sand Recycling
Global foundries generate 100 million tons of spent sand annually, with only 28% currently recycled. The physical properties of foundry sand, including angular grain structure (65-85 AFS GFN) and residual binder content (0.8-1.2%), create unique reclamation challenges. Our advanced thermal- mechanical systems achieve 94% reuse rates, reducing landfill costs by $18-42/ton while maintaining permeability standards (80-110 for returned sand vs. 40-60 for virgin material).
Breakthrough Technology for Maximum Recovery
Patented multi-stage processing combines:
- Precision screening (mesh accuracy ±0.01mm)
- Low-temperature thermal reactivation (150-200°C vs. conventional 450°C)
- Electrostatic dedusting (99.7% particulate removal)
This preserves properties of foundry sand better than rotary kiln systems, maintaining 92% original compressive strength versus 78% in competitor models.

FAQS on foundry sand recycling
Q: What is foundry sand recycling?
A: Foundry sand recycling is the process of reusing sand from metal casting operations after treatment to remove contaminants. It reduces waste and conserves natural resources. This practice supports sustainable manufacturing and lowers disposal costs.
Q: How is foundry sand recycled for reuse?
A: Foundry sand is recycled by mechanically separating binders, metals, and debris through screening, crushing, or thermal treatments. The cleaned sand is then tested for quality before reuse in construction, concrete, or new casting molds. Proper recycling ensures compliance with environmental regulations.
Q: What are the key physical properties of foundry sand?
A: Key physical properties include grain size distribution, permeability, and thermal stability. Foundry sand typically has uniform particle shapes and high heat resistance. These properties make it suitable for metal casting and construction applications.
Q: Can recycled foundry sand be used in construction materials?
A: Yes, recycled foundry sand is commonly used in asphalt, concrete, and road base materials. Its physical properties, like durability and permeability, enhance material performance. Proper testing ensures it meets safety and quality standards.
Q: How do physical properties affect foundry sand recycling efficiency?
A: Properties like grain size and clay content determine how easily contaminants can be removed. Uniform particles improve screening and thermal processing efficiency. Optimal physical traits reduce energy and cost during recycling.
