Project Overview: In order to expand and extend the industrial chain and build an industrial integration development system, Yibin Huafu Shuangsan Cement Building Materials Co., Ltd. has built a new production line with an annual output of 5 million tons of fine machine-made sand. The entire industrial park covers an area of more than 90 acres. The investment in the new machine-made sand production line project exceeds 50 million. The crushing and sand making system adopts a complete set of equipment from Chongqing Sanming Heavy Industry, focusing on energy saving, environmental protection, high efficiency and high quality. It will reduce costs and increase efficiency for the company's cement and concrete production, and will be exported to Yibin, Chengdu, Neijiang, Jianyang and other southern Sichuan regions.
