A wet sand production line project designed and constructed by Sichuan Xinyida Machinery Co., Ltd. has been completed and is now officially put into production. The project strictly complies with the environmental protection requirements, and the closed production is pollution-free. Through the wet sand making process, the stone materials are finally crushed and screened to produce high-quality machine-made sand that meets the customer's requirements. The project will continue to improve the plant closure, greening and other ancillary works, and improve the green mine construction of higher standards.
