According to the people's government of Xiangzhou County in Guangxi, the first phase of the project of Daming Mining Green Building Material Industrial Park in Xiangzhou, Guangxi, with an annual output of 10 million tons of aggregates, was officially put into operation in early April this year. The products mainly serve the Guangdong-Hong Kong-Macao Greater Bay Area and supply the local infrastructure.
It is understood that the Daming Xiangzhou Green Building Material Industrial Park was established in January 2021. The project mine, the limestone mine for construction in Shilong Town, Xiangzhou County, has a resource reserve of about 95 million tons, with a total planned investment of about 1.8 billion yuan, which will be constructed in two phases. The total investment of the first phase of
the Daming Mining Production Line
Project is about 1.1 billion yuan, mainly for the construction of a comprehensive utilization production line of green building materials with an annual output of 10 million tons of green building aggregates, machine-made sand, subsidiary stone powder and other green building materials, supporting special wharfs and related facilities such as wharfs serving the surrounding areas for water transportation and circulation. The main products are fine aggregate, fine machine-made sand, limestone raw materials for flux, limestone raw materials for cement, superfine heavy calcium, limestone raw materials for superfine light calcium, etc. In the
second phase, a new high-grade limestone processing production line with an annual output of 10 million tons will be built in Daming Xiangzhou Green Industrial Park. The main products are 4 million tons of limestone raw materials for metallurgical flux, 5 million tons of limestone raw materials for cement and 1 million tons of limestone raw materials for ultra-fine heavy calcium and ultra-fine light calcium. The main construction contents include new crushing station and ancillary facilities such as supporting conveyor corridor, safety facilities and environmental protection facilities. The products
of Daming Mining are loaded on cargo ships at Mengshan Port and sent to Dawan District
. "Our main products are serving Dawan District.". Customers enter information by placing orders online. The factory adopts GPS vehicle intelligent dispatching system to identify QR Code or license plates and dispatch vehicles to load materials from the factory to the loading channel. The whole process of delivery is automated and convenient. Kuang Jiaqiang, head of Daming Mining Company, said.
The whole production line adopts intelligent DCS automatic central control system, from mining, crushing, soil screening, shaping crushing to conveyor belt transportation, grading screening, machine-made sand crushing, shaping, rotary powder, modulus control, mixing and other processes, all of which realize production automation. On the huge production line, there are few workers except those who carry out safety inspection before the equipment is opened. "We choose advanced production technology and equipment in China, and adopt intelligent factory management mode.". Advanced intelligent technologies such as DCS intelligent central control system, video inspection and monitoring system, three-dimensional digital ore body system, GPS vehicle intelligent dispatching system, blasting (mining) design system, resource reserve management system, production management system and drilling and blasting database are armed to every production link to create intelligent mines and factories. Wang Peng, deputy general manager of Daming Mining, said proudly.
When it comes to the mining industry, many people have the impression that the dust is flying everywhere and the noise is deafening. In Daming Xiangzhou Green Building Material Industrial Park, such scenes are rarely seen. The green mine has been realized here, thanks to the advanced dust removal system and perfect storage equipment.
"We have 98 sets of dust collectors in the whole plant, which can ensure that all the nodes of each production process, such as crushing, soil screening, transportation, grading and screening, are equipped with dust collectors, and all the dust collectors are stored in a powder tank.". All products and intermediate products have corresponding storage bins to ensure that products are not stacked in the open air. Make the factory area clean and tidy, and will not pollute the surrounding environment. Wang Peng said. The 14th Five-Year Plan for the Development of Industry and Information Technology
in Xiangzhou County proposes to build an ecological industrial system for the intensive processing of calcium carbonate, which integrates the development, production, application and logistics of green mining, restoration and intensive processing products, in accordance with the development ideas of "resource integration, high-end products, diversified functions and green industry". Promote the development of calcium carbonate industry to high-end, green, recycling and intellectualization, and achieve output value of more than 10 billion yuan by 2025.
According to the development plan of calcium carbonate industry, Xiangzhou County has made great efforts on a small stone to strengthen the service of calcium carbonate industry from five aspects: establishing coordination mechanism, encouraging scientific and technological innovation, supporting stronger and bigger, increasing financial support, and ensuring factor guarantee in place.
We have established a coordination mechanism to coordinate and solve major problems and major issues in the development of calcium carbonate industry in the county in a timely manner, and encourage calcium carbonate production enterprises to carry out scientific and technological innovation. Give rewards to the enterprises that have reached the upper level of regulations; at the same time, increase the financial support to solve the financing problems. In recent two years, the calcium carbonate industry enterprises in Xiangzhou County have obtained the "Guihui Loan" with a 56729 of 80,000 yuan and a preferential interest of 8.3213 million yuan. In terms of land use, forest use, energy use and power supply, they have provided strong protection to help the calcium carbonate industry develop in a green, healthy and sound way. Wei Wenmin, Director of Service Enterprise Office of Xiangzhou County Economic and Trade Bureau, said.
According to statistics, as of April 2023, there are 11 calcium carbonate industrial enterprises above the scale in Xiangzhou County, and the main products of the industry are cement and aggregate. In 2022, the output value of calcium carbonate scale industry in the county was 570 million yuan, an increase of 25% over the previous year, and in January-April 2023, the output value was 480 million yuan, an increase of 213% over the previous year.
