Product Description
Our advanced Furan Resin Sand (Self-hardening Sand) Recovery System is meticulously tailored to efficiently manage the rejuvenation of aged sand, perfectly aligning with your specific sand recovery volumes.
Resin sand, a specialized core sand, ingeniously uses resin as its binding agent. The process of rejuvenating old sand effectively strips away the binding film enveloping the sand grains, ensuring an economical alternative to fresh sand. By reclaiming the sand, we achieve four key objectives: conserving new sand, reducing transportation expenses associated with discarding old sand, and guaranteeing uniform, smooth, and thermally stable sand particles. This not only enhances the quality of castings but also optimizes the reuse of resin sand, permitting lower resin additions and thus cutting down resin costs. Moreover, it significantly mitigates the environmental impact from waste sand disposal. Our production line is also adept at processing sodium silicate sand casting, as the methodologies for both are quite alike.
Our state-of-the-art resin sand production line boasts a regeneration processing system capable of delivering an impressive annual output ranging from 3,000 to 10,000 tons of castings. Equipped with advanced PLC control, it meticulously coordinates the electrical equipment, ensuring stringent protection and seamless operation. The innovative simulation screen guarantees operational stability and reliability, marking a new era of automatic production excellence.
The meticulous process flow of our resin sand production line begins post-pouring with the strategic hoisting of sand boxes and castings onto our inertia vibration shakeout machine. Here, large jacket pieces and risers are expertly sorted by hand while sand, sand masses, and small cold iron fragments pass through the falling sand grid to the magnetic separation belt conveyor. After magnetic separation, materials proceed to the multifunctional vibrating crushing and regenerating machine for intensive crushing and stripping. Upon screening, sand moves to the 1# bucket elevator, ascending to the centrifugal rotor secondary regenerator for vigorous regeneration and comprehensive stripping. The regenerated sand, now free from fine powder, dust, and resin film, transitions through the flow curtain air separator. This separator connects seamlessly with both the cyclone dust collector and the pulse-type back blowing dust collector to efficiently remove residuals. The journey continues as sand is further elevated by the 2# bucket elevator to the sand warehouse. Here, the dynamic mobile double-arm continuous resin sand mixer, ingeniously linked via a pneumatic shutter, receives flowing sand from the storage. Within the mixer, sand advances through a screw blade to initiate mixing, augmented by the proximal addition of curing agents and resin. Through meticulous premixing, these blend into the sand, culminating in a well-mixed composition that is automatically channeled into the ready sand box for modeling and core crafting. Post-treatment, the tire traverses to the self-hardening zone or undergoes alcohol brushing for combustion treatment, culminating in a final brushing with release material, drying, and box closure for pouring and cooling.
