Product Description
Introducing our advanced Furan Resin Sand (Self-hardening Sand) Recovery System. This innovative, tailor-made solution is meticulously designed to accommodate varying volumes of old sand recovery, ensuring efficiency and sustainability.
Resin sand, a specialized core sand enhanced with resin as a binder, is revolutionized through our regeneration process. This technique meticulously removes the binder film from sand surfaces, optimizing particle size and allowing the sand to serve as a cost-effective alternative to new sand. The regeneration of old sand serves multiple environmental and economic benefits: reducing new sand consumption, cutting transportation costs, producing uniformly smooth sand particles, and enhancing the heat setting capability. This process significantly elevates casting quality, especially with reused resin sand that requires less resin input, thus reducing material costs. Furthermore, it mitigates the environmental impact caused by waste sand disposal. Additionally, our production line is versatile, catering to both resin and sodium silicate sand casting processes with similar methodologies.
Our state-of-the-art resin sand production line is engineered for high-capacity outputs, ranging from 3000 to 10000 tons annually. Featuring PLC-controlled electrical equipment, the system ensures maximum safety and security, with an intuitive simulation screen that displays the stability and reliability of the operations, enabling seamless automation throughout the production cycle.
The comprehensive process flow of our resin sand production line is designed for maximum efficiency and quality. Post-pouring, sand boxes and castings are elevated to the inertia vibration shakeout machine. Larger jackets and risers are manually sorted while sand, sand masses, and small pieces of cold iron fall through the grid to a magnetic separation belt. Post-magnetic separation, materials move to a multifunctional vibrating crusher for pulverization and stripping, followed by screening. The screened sand is sent via bucket elevators to a centrifugal rotor secondary regenerator, where robust regeneration and stripping occur. The resultant mix, comprising fine powder, dust, and resin film, transitions to a flow curtain air separator. Integrated with cyclone and pulse-type back blowing dust collectors, the system efficiently eliminates fine particles and dust. Subsequently, regenerated sand is transported to the sand warehouse, poised for further processing. The mobile double-arm continuous resin sand mixer, linked to the sand storage, facilitates seamless sand flow into the mixer. Within, the sand progresses forward, receiving curing agent and resin inputs calibrated precisely, culminating in thorough mixing. The well-blended mixture is then directed into sand boxes for superior modeling and core creation. Upon transportation to the self-hardening zone or after alcohol paste combustion treatment, the casting is brushed with release material, dried, and boxed for the final pouring and cooling stages.
