Resin sand production line is composed of magnetic separation belt conveyor, vibration crushing re-vitality, centrifugal rotor secondary secondary re-vitality, sand library, bucket elevator (3 sets), moving double arms continuous resin sand mixer, pulse back blowing dust collector and other equipment.

Technological process of resin sand production line: the sand box and castings after pouring are lifted by crane to inertial vibration sand shaker, after sand shaker treatment, the castings are transported to the cleaning and shoveling workshop, and the sand box is transported to the sand box warehouse for later use. Large pieces of cleat, riser by manual sorting, through the shakeout grid sand, sand and small cold iron to magnetic separation belt machine, after magnetic separation to the multifunctional vibration crushing reclaimer for crushing, membrane, screening, after screening, the sand into the bucket elevator, the elevator up to the rotor of the centrifugal secondary reclaimer for strong regeneration, fully to take off the membrane. Recycled sand mixed with micro powder, dust and resin film flows into the flow screen air cleaner through the flow sand trough, and the air cleaner is connected with the cyclone dust remover and the pulse type back-blowing dust remover to remove micro powder and dust. The reclaimed sand is then lifted to the sand storage by the bucket elevator for later use. The pneumatic gate is connected with the sand outlet below the sand bin. Press the sand mixing button in the electric control box of the sand mixer, and the pneumatic gate will open automatically. The sand with a fixed amount will flow into the sand mixer from the sand bin. In the sand mixer, sand is sent forward by spiral blades to the starting end of sand mixing, curing agent is added from the proximal control valve, and resin is added to the proximal valve behind after being stirred by small blades to enter the sand mixing end. Curing agent, resin and regenerated sand are fully mixed and sent to the front discharge port to flow into the prepared sand box automatically for molding and core-making. This equipment is imported PLC (programmable control) control automation excellent performance, suitable for resin sand process of small and medium-sized foundry enterprises.
