Recently, Zhejiang Jiaogong Group Co., Ltd. Hereinafter referred to as "Zhejiang Jiaogong" (EPC + O), the general contractor of Jiangshan Mine's aggregate production line with an annual output of 3.3 million tons has been put into trial operation, which indicates that the project has met the operation conditions and entered the commissioning and production period in an all-round way. In the next step, Jiangshan Mine Project will integrate and upgrade intelligent management, continue to focus on safety management and control, coordinate the development of green ecology, constantly promote cost reduction and efficiency enhancement, and do a good job in production commissioning to ensure smooth production by the end of April.
It is understood that the total investment of the project is about 450 million yuan, the total land area of the processing production line is about 80 mu, the main construction area is 14914 square meters, there are two sand aggregate production lines, after the project is completed and put into operation, the annual output will reach 3.3 million tons, the annual output value is estimated to be 250 million yuan, and the annual tax payment will exceed 20 million yuan.
As an important part of the project, the sand and gravel aggregate production line adopts the top-down stepped layered mining and three-stage crushing process. A total of 35 belt conveyors, 9 vibrating screens, 7 crushers and 63 feeders are installed. The main equipment used, such as CC400S cone crusher, VS 1500R vertical shaft crusher, JC1300 jaw crusher and HPF1560 heavy vibrating feeder, has the advantages of high automation, strong operation safety and small impact on the ecological environment. The production line adopts intelligent management system, which integrates all kinds of data with computer network, centralized control management and remote monitoring, greatly reduces labor costs and improves production efficiency. On October 25,
