Product Description
Experience the cutting-edge Furan Resin Sand Recovery System—designed with precision to accommodate varying recovery needs of old sand. Tailored to perfection, this state-of-the-art system ensures maximum efficiency and adaptability.
Resin sand, a revolution in core sand technology, utilizes resin as its binding agent to create superior casting molds. The meticulous regeneration process effectively removes the binder film, optimizing particle surface size for reuse. This highly efficient system not only conserves new sand resources and minimizes transportation costs but also enhances the homogeneous nature of recycled sand particles. Enjoy the benefits of its smooth surface and excellent heat resistance, which significantly elevate casting standards. By reprocessing resin sand, you reduce resin costs and environmental impact, paving the way for a sustainable future. Compatible with sodium silicate sand casting, this versatile production line seamlessly adapts to similar sand processing techniques.
Meet the next-level resin sand production line—engineered to regenerate up to 10,000 tons of castings annually. It harnesses the power of PLC-controlled automation with rigorous protection measures to ensure stable, reliable operation. The intuitive simulation screen empowers seamless monitoring, embodying the epitome of automated efficiency.
Delve into the intricate process flow of our resin sand production line, where innovation meets precision. Post-pouring, the sand box and castings are effortlessly lifted to the cutting-edge inertia vibration shakeout machine. Here, large jackets and risers are carefully sorted by hand, while sand and small cold iron fragments pass through a magnetic separation conveyor. This expertly segregated material is then processed in a multi-functional vibrating machine that crushes, strips, and screens the sand. The refined sand is elevated to the centrifugal rotor regenerator, where it undergoes robust regeneration and stripping. Moving forward, the sand mixed with fine powder, dust, and resin film is air-separated to effectively remove impurities. The addition of cyclone and pulse-type back-blow dust collectors ensures the pristine quality of the sand. Further elevated and stored, the sand flows seamlessly into a mobile double-arm mixer, where each grain is expertly blended with a curing agent and resin before being destined for casting excellence. The tire is then taken to a self-hardening area or treated with alcohol paste before the final steps of drying, box closure, and cooling.
