Product Description
Introducing the Furan Resin Sand (Self-hardening Sand) Recovery System, tailored meticulously to accommodate varying quantities of reclaimed old sand. This innovative system ensures maximal efficiency in sand recovery, providing a bespoke design to meet your specific needs and optimize sand reuse.
Resin sand, a core sand bonded by resin, plays a pivotal role in the regeneration of old sand. This process is designed to meticulously strip the binder film from the sand particles, enhancing its surface quality and particle size. By effectively recycling, it serves as a cost-effective alternative to new sand. The benefits are multifaceted: reduced consumption of new sand, minimized disposal expenses, and consistent sand particle smoothness and thermal properties. This not only elevates casting quality but also permits a reduction in resin addition, thereby lowering costs. Furthermore, it significantly mitigates environmental pollution caused by waste sand disposal. The line accommodates sodium silicate sand casting, sharing a similar processing methodology.
Our state-of-the-art resin sand production line, boasting an impressive annual output ranging from 3000 to 10000 tons of castings, is a hallmark of innovation and efficiency. Equipped with cutting-edge PLC control, the system ensures comprehensive management and protection of electrical components. The integration of a simulation screen guarantees stable and reliable operation, paving the way for seamless, automated production.
Process flow of resin sand production line: Post-pouring, sand boxes and castings are elevated to an inertia vibration shakeout machine. Here, manual sorting segregates larger jacket pieces and risers, while sand, sand mass, and smaller cold iron pieces descend through the shakeout grid to the magnetic separation belt conveyor. Following magnetic separation, materials proceed to the multifunctional vibrating crushing and regenerating machine for thorough crushing and stripping. Subsequently, screened sand is transported via 1# bucket elevator to the centrifugal rotor secondary regenerator, where robust regeneration and complete stripping occur. Regenerated sand, interspersed with fine powder, dust, and resin film, is directed through the flow sand tank to the flow curtain air separator. This separator collaborates with the cyclone dust collector and pulse type back-blowing dust collector to eradicate fine powder and dust. The rejuvenated centrifugal rotor's sand is then transferred to the sand storage via the 2# bucket elevator, ready for further processing. The mobile double-arm continuous resin sand mixer connects its upper feed port with the sand storage outlet via a pneumatic shutter, allowing sand flow into the mixer. Within, the sand advances through screw blades, initiating mixing. A proximal control valve introduces the curing agent, followed by resin addition through a small blade for preliminary mixing before entering the final mixing stage. Here, the curing agent, resin, and regenerated sand blend thoroughly, reaching the front discharge port for seamless transition into prepared sand boxes for modeling and core making. Final steps involve transportation to the self-hardening area or alcohol paste brushing for combustion treatment, before a final brushing with release material, drying, box closure, pouring, and cooling.
