AI Technical Summary
Existing methods for preparing coal gangue ceramsite suffer from problems such as low solid waste content, high calcination energy consumption, poor weathering resistance, and the risk of heavy metal leaching, as well as poor molding stability, making it difficult to achieve efficient resource utilization.
Through a process flow including pretreatment, component detection, regulator addition, homogenization mixing, segmented sintering, and gradient cooling, including coal gangue desulfurization, graded crushing, grinding, auxiliary material pretreatment, composite regulator application, and segmented sintering, the particle size distribution and composition control of coal gangue are optimized to ensure the high performance and stability of ceramsite.
It significantly improves the solid waste disposal efficiency of coal gangue, reduces energy consumption and the risk of heavy metal leaching, enhances the performance stability and yield of ceramsite, and meets the construction industry's demand for high-performance lightweight aggregates.
