Furan resin sand recovery system
Furan resin sand (Self-hardening Sand) sand recovery system, customized design according to the amount of old sand recovery
product details

Resin sand is a type (core) sand with resin as a binder. The regeneration of old sand is to remove the binder film on the surface of the sand to the maximum extent, adjust the surface (particle size) of the sand, and use it as a very economical substitute for new sand. The old sand is recycled for four purposes, which can save new sand consumption and transportation costs for discarding old sand, and the recycled sand particles are even. The surface is smooth and the heat is set well. It is beneficial to improve the quality of castings, especially when the resin sand is recycled and reused, and the amount of resin added can be reduced. Reduce the cost of resin. It can also reduce environmental pollution caused by the discharged waste sand. The production line can also be processed for sodium silicate sand casting, and the sand processing process of the two is similar.

Self-setting sand and furan resin sand casting site

resin sand production line regeneration processing system with an annual output of 3000 tons to 10000 tons of castings. PLC control is adopted to control the electrical equipment, which is fully restricted and protected. The simulation screen shows that the work is stable and reliable, realizing automatic production.

Process flow of resin sand production line: After pouring, the sand box and castings are hoisted to the inertia vibration shakeout machine. Large pieces of jackets and risers are manually sorted, and the sand, sand mass and small pieces of cold iron through the falling sand grid fall to the magnetic separation belt conveyor, and after magnetic separation, they are transported to the multi-functional vibrating crushing and regenerating machine for crushing and stripping. , Screening, the sand after screening is sent to 1# bucket elevator, and is lifted from the elevator to the centrifugal rotor secondary regenerator for strong regeneration and full stripping. The regenerated sand mixed with fine powder, dust and resin film flows into the flow curtain air separator through the flow sand tank. The air separator is connected with the cyclone dust collector and the pulse type back blowing dust collector to remove the fine powder and dust. The secondary and secondary regenerator of the regenerated centrifugal rotor and the sand in the sand warehouse are then lifted to the sand warehouse for standby by the 2# bucket elevator. The upper feeding port of the mobile double-arm continuous resin sand mixer is connected with the sand outlet at the bottom of the sand storage by the pneumatic shutter. The sand flows into the mixer from the sand storehouse. In the sand mixer, the sand is transported forward through the screw blade to the beginning of sand mixing, the curing agent is added from the proximal control valve, and the resin is added to the proximal valve after premixing by the small blade, and then enters the sand mixing end. The curing agent, resin and regenerated sand are fully mixed and then sent to the front discharge port to automatically flow into the prepared sand box for modeling and core making. The tire is transported to the self-hardening area or brushed with alcohol paste for combustion treatment, and finally brushed with release material to dry and close the box for pouring and cooling.
