On May 27, the 2024 Forum on the Release of Intelligent Achievements in Clean and Efficient Coal Utilization and the Construction of Intelligent Coal Preparation Plants was held in Zaozhuang City, Shandong Province. Academicians, industry leaders, and well-known experts were invited to the forum, where they jointly showcased cutting-edge innovative applications and recognized advanced achievements, innovative teams, and representatives of outstanding contributions in the intelligent utilization of clean and efficient coal
At this forum, DFMC 's "Significant Breakthrough in Intelligent Dense-Medium Coal Preparation Supported by High-Precision Coal Quality Analyzer" was successfully selected as an advanced achievement in the intelligent utilization of clean and efficient coal for 2024. Zhao Hongtao, Deputy General Manager and Senior Engineer of DFMC, served as the presenter of the project achievement and delivered a report, introducing in detail the application of this achievement at the Huajin Shaqu Coal Preparation Plant of Shanxi Coking Coal Group. After the application of the neutron activation coal quality analyzer developed by DFMC at this coal preparation plant, remarkable results were achieved: the dynamic standard deviation of the hourly ash content of clean coal was ≤ 0.15%, the total clean coal recovery rate increased by more than 0.6%, and the economic benefits created in that year reached over 60 million yuan. Appraised by the China Coal Industry Association, this project reached the international leading level.
Currently, the high-precision online coal quality analyzer has achieved accurate multi-index detection and analysis of coal quality at different beneficiation process points. It enables precise measurement of key coal quality indicators such as ash content, moisture, total sulfur, and iron content in raw coal, dense medium clean coal, total clean coal, and loaded commercial coal. The dynamic measurement error of ash content is consistently maintained within ±0.15%, meeting the requirements for accurate online ash data in the intelligent control of coking coal preparation plants.
Additionally, DFMC comprehensively demonstrated its integrated intelligent coal preparation solution. This solution seamlessly integrates a series of advanced technologies, including high-precision coal quality analyzers, intelligent dry separators, intelligent inspection & testing systems, intelligent dense-medium separation control systems, and comprehensive management platforms, encompassing online detection instruments, intelligent equipment, and smart management systems.Leveraging these core strengths, DFMC has successfully implemented high-quality, high-efficiency intelligent coal separation and production management projects for numerous leading coal enterprises—including State Power Investment Corporation (SPIC)andChina Energy Investment Corporation (CEIC)—earning widespread acclaim and high recognition within the industry.
Significantly, the intelligent coal blending and storage system project implemented by DFMC at Huaibei Mining's Waibei Coal Preparation Plant contributed to the plant's selection for the list of advanced achievements released at this event.
This project fully integrates DFMC 's neutron activation online elemental analyzer with a 3D bin level gauge. It enables precise acquisition of coal quality data and layered modeling and display of ash content in coal bunkers, thus providing strong support for precise coal blending.
During the forum, senior executives from State Energy Ulan Energy, State Energy Baotou Energy, State Energy Yulin Energy, Shaanxi Coal Group, Huaibei Mining, Yongcheng Coal & Electricity Group, Zaozhuang Mining, China Coal Huajin, Sanhekou Mining, and other enterprises, along with industry experts, visited the DFMC booth for in-depth exchanges. They engaged in highly productive discussions with the DFMC team on topics such as technical cooperation and the intelligent upgrade of traditional coal preparation plants, laying a solid foundation for further deepening cooperation.
