To address the challenges of abandoned mine site management and explore sustainable development paths, the user company, focused on mine filling management needs, strategically entered the solid waste-based filling material market. Focusing on customized grinding and deep processing services, the company provides mining companies with high-performance filling base materials, deeply embedded in the green mine construction supply chain. In line with the green development trend, fluorogypsum and slag have become a "treasure." Their use in mine filling not only addresses the land occupation and pollution issues of waste materials, achieving resource recycling, but also reduces filling costs, strengthens the mining area, and mitigates the risk of ground collapse, promoting sustainable development in the mining industry and successfully turning waste into treasure. In the early stages of the project, the team conducted an in-depth review of numerous commercially available equipment, conducting a comprehensive evaluation based on multiple dimensions, including performance, energy consumption, reliability, and maintenance costs. After repeated comparisons, the team ultimately selected the Zenith Machinery LM vertical roller mill, which ensures the guaranteed particle size distribution and powder activity of the filling material, providing a critical foundation for the stability of the filling project and system reliability.
