This series of single and double pipe continuous resin sand mixing machine is mainly used for mixing resin self-hardening sand and sodium silicate sand. USES: Adhesive feeding system adopts advanced gear pump, diaphragm pump, liquid detector, accurate quantification. . Sand mixing time is short, headless tailings loss. Flexible rotation of arms, large operating area. Fully open sand mixing cage arm, easy to clean or adjust the blade, easy to operate and maintain. Reduce the amount of binder, improve the quality of molding sand, get good economic benefits. PLC control is adopted in the electrical system, which is fully controlled and protected, and the analog screen is displayed. The work is stable and reliable, and the automatic production is implemented.
