The coated sand production line is a complete set of equipment specifically used for manufacturing coated sand, which is mainly applied in the casting industry. The production line produces high-strength, high-temperature resistant, and good fluidity coated sand by evenly coating the heat-resistant resin on the surface of the sand. It is used to manufacture complex-shaped, high-precision castings. The coated sand production line has the characteristics of high automation, high production efficiency, and energy conservation and environmental protection. It can be designed and customized according to different needs.
