S.L Machinery Brick Machine: Innovative Solution for High-Value Utilization of Bauxite Residue

赤泥作為氧化鋁工業的联机典型固廢，我國赤泥年排放量超億噸，械砖累計堆存規模龐大，机设解决傳統堆存模式不僅占用土地，备赤更存在環境汙染隱患。泥高在“雙碳”目標與循環經濟政策的值利推動下，赤泥資源化利用正迎來重要轉型機遇。创新

Bauxite residue,联机 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.

赤泥回收現狀與技術突破

Current Status and Technological Breakthroughs in Bauxite Residue Recycling

目前，我國赤泥綜合利用率為4%左右，械砖主要用於水泥生產、机设解决建築砌塊等領域。备赤

由於赤泥成分複雜、泥高堿含量高、值利處理難度大特性，创新導致其綜合利用長期麵臨技術瓶頸。联机三聯機械磚機設備通過創新工藝開發，突破赤泥與其他固廢（如建築垃圾、粉煤灰、尾礦）的協同處置技術，構建“成分調控—材料再生—製品成型”的製磚解決方案。三聯機械磚機設備可將赤泥等固廢轉化為均勻穩定的再生骨料，顯著降低原料堿性，成功應用於透水磚、路岩石、護坡磚等建材生產，推動赤泥從“環境負擔”向“資源載體”轉變。

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."

展望未來

Looking Ahead

隨著技術進步和政策支持，赤泥回收利用將迎來新的發展機遇。三聯機械以技術創新為核心，通過裝備研發與工藝優化，積極探索將赤泥、煤矸石、尾礦等工業固廢的資源化再生利用，致力於為行業提供可複製的固廢資源化解決方案。

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.
