Product Description
Introducing our innovative Furan Resin Sand (Self-hardening Sand) recovery system, meticulously crafted and tailored to suit the specific volume of old sand you anticipate recovering. Experience the perfect blend of performance and customization.
Resin sand, known for its binder-rich composition, undergoes a transformative regeneration process that meticulously eliminates the binder film covering the sand's surface. This alteration optimizes the sand's texture and size, rendering it a cost-effective alternative to new sand. The recycling of old sand serves four pivotal functions: it significantly curtails the consumption of new sand, reduces discarding transportation costs, and ensures the recycled particles maintain uniform size, smooth surfaces, and optimal heat setting. This reclamation process notably enhances casting quality, especially when the recycled resin sand is reused, allowing for a reduction in added resin. Consequently, production costs are minimized, and environmental pollution from waste sand disposal is substantially reduced. This versatile production line is also applicable for sodium silicate sand casting, as both sand processing methods share similarities.
Our resin sand production line boasts an impressive annual capacity, ranging from 3,000 to 10,000 tons of superior castings. Employing state-of-the-art PLC control for electrical equipment, the system ensures comprehensive protection and restriction. The simulation screen confirms the operational stability and reliability, achieving seamless automatic production at its finest.
The resin sand production line process unfolds as follows: Post-pouring, the sand box and castings are elevated to the inertia vibration shakeout machine. Here, manual sorting removes large jackets and risers, while sand, sand masses, and small cold iron pieces descend through the sand grid to the magnetic separation belt conveyor. Following magnetic separation, the materials proceed to the multi-functional vibrating crushing and regenerating machine for thorough crushing and stripping. Screened sand advances to the 1# bucket elevator, which transports it to the centrifugal rotor secondary regenerator for extensive regeneration and total stripping. The regenerated sand, now mixed with fine powder, dust, and resin film, is directed into the flow curtain air separator via the flow sand tank. The separator, linked to a cyclone dust collector and pulse-type back-blowing dust collector, efficiently removes fine contaminants. The sand, through a network of regenerators and elevators, is stored in the sand warehouse, ready for further processing. The mobile double-arm continuous resin sand mixer connects to the sand storage via a pneumatic shutter, seamlessly delivering sand for mixing. Within the mixer, sand progresses via screw blades to the mixing start point, where curing agents and resin are methodically blended, ensuring a consistent mixture before reaching the discharge port. The blend flows into the prepared sand box for precision modeling and core creation. These modeled forms are then transported to the self-hardening area or treated with an alcohol-based paste for combustion treatment, culminating in a release material coating to set, dry, and close the box for casting and cooling.
