Furan resin sand (Self-hardening Sand) sand recovery system, meticulously tailored to suit the specific volume of old sand recovery, ensuring maximum efficiency and sustainability.

Resin sand, a core sand variant, uniquely utilizes resin as a binder. The regeneration process of old sand focuses on effectively stripping the binder film from the sand's surface, finely adjusting its surface and particle size, and repurposing it as an incredibly cost-effective alternative to new sand. The recycled sand serves quadruple purposes, significantly reducing new sand consumption and transportation costs, all while delivering uniformly smooth particles that set with excellent thermal properties. Enhancing casting quality, this process particularly shines when the resin sand is recycled and reused, allowing for a reduction in resin usage and consequently, its costs. Additionally, it curtails environmental pollution associated with waste sand disposal.

Our state-of-the-art resin sand production line boasts an impressive regeneration processing system, capable of producing between 3000 to 10000 tons of castings annually. Utilizing advanced PLC control, the entire electrical system is meticulously safeguarded and monitored, guaranteeing stability and reliability. The sophisticated simulation screen facilitates seamless automatic production, ensuring consistent high-quality output.

Process Flow: Post-pouring, sand boxes and castings are elevated to the inertia vibration shakeout machine. Here, large jackets and risers are sorted manually, while sand masses descend through magnetic separation to a multi-functional vibrating crushing and regenerating machine. Screened sand is lifted to a centrifugal rotor secondary regenerator for intense stripping. The regenerated sand is cleaned of fine powder and dust via a flow curtain air separator connected to dust collectors. Finally, the mobile double-arm continuous resin sand mixer precisely blends sand with curing agents and resins for modeling and core creation.
