S.L Machinery Brick Machine: Innovative Solution for High-Value Utilization of Bauxite Residue
赤泥作为氧化铝工业的典型固废，我国赤泥年排放量超亿吨，累计堆存规模庞大，传统堆存模式不仅占用土地，更存在环境污染隐患。在“双碳”目标与循环经济政策的推动下，赤泥资源化利用正迎来重要转型机遇。
Bauxite residue, a typical solid waste from the alumina industry, is generated in large quantities in China, with annual emissions exceeding 100 million tons and a substantial cumulative storage scale. Traditional storage methods not only occupy a significant amount of land but also pose potential environmental pollution risks. Under the impetus of the "dual carbon" goals and circular economy policies, the resource utilization of bauxite residue is facing an important opportunity for transformation.
赤泥回收现状与技术突破
Current Status and Technological Breakthroughs in Bauxite Residue Recycling
目前，我国赤泥综合利用率为4%左右，主要用于水泥生产、建筑砌块等领域。
由于赤泥成分复杂、碱含量高、处理难度大特性，导致其综合利用长期面临技术瓶颈。三联机械砖机设备通过创新工艺开发，突破赤泥与其他固废（如建筑垃圾、粉煤灰、尾矿）的协同处置技术，构建“成分调控—材料再生—制品成型”的制砖解决方案。三联机械砖机设备可将赤泥等固废转化为均匀稳定的再生骨料，显著降低原料碱性，成功应用于透水砖、路岩石、护坡砖等建材生产，推动赤泥从“环境负担”向“资源载体”转变。
Currently, the comprehensive utilization rate of bauxite residue in China is around 4%, mainly used in cement production and building block manufacturing.
Due to its complex composition, high alkalinity, and difficulty in processing, bauxite residue has long faced technological bottlenecks in comprehensive utilization. S.L Machinery's brick-making equipment, through innovative process development, has broken through the co-processing technology of bauxite residue with other solid wastes (such as construction waste, fly ash, and tailings), and has established a brick-making solution that integrates "component regulation—material regeneration—product formation." S.L Machinery's brock machine can transform bauxite residue and other solid wastes into uniform and stable recycled aggregates, significantly reducing the alkalinity of the raw materials. This has been successfully applied in the production of permeable bricks, curbstones, and slope protection bricks, promoting the transformation of bauxite residue from an "environmental burden" to a "resource carrier."
展望未来
Looking Ahead
随着技术进步和政策支持，赤泥回收利用将迎来新的发展机遇。三联机械以技术创新为核心，通过装备研发与工艺优化，积极探索将赤泥、煤矸石、尾矿等工业固废的资源化再生利用，致力于为行业提供可复制的固废资源化解决方案。
With technological advancements and policy support, the recycling and utilization of bauxite residue will face new development opportunities. S.L Machinery, with technological innovation at its core, is committed to exploring the resource regeneration and utilization of industrial solid wastes such as bauxite residue, coal gangue, and tailings through equipment development and process optimization. The company aims to provide replicable solid waste resource utilization solutions for the industry.
