Foundry Uses Old Sand Equipment for Coated Sand.

The Coated Sand Regeneration Line is a set of efficient and environmentally friendly equipment designed to solve the problem of recycling and reusing waste coated sand (shell molding sand) in the foundry industry. It uses a series of physical and chemical processes to remove residual resin and other impurities from used sand, restoring its original properties for reuse in high-quality casting production.

This regeneration line integrates key processes such as crushing, screening, magnetic separation, thermal regeneration, cooling, and screening. With modular design, it can be customized according to customer requirements and integrated with intelligent control systems, dust removal systems, and exhaust gas purification devices to meet the needs of modern green foundries.

Thermal regeneration temperature up to 600–800°C ensures over 95% binder removal rate, greatly improving the quality of regenerated sand.
