Raw Material Preparation:
Bauxite: Our premium bauxite is meticulously chosen for its superior alumina content (Al2O3) and low impurity levels, setting the foundation for a top-tier product.
Iron filings or scrap iron: Strategically integrated into the mix to enhance the efficiency of the reduction process during fusion.
Anthracite coal: Employed as a powerful reducing agent, facilitating seamless reactions.
Fusion:
Electric Arc Furnace (EAF): The precisely prepared blend enters the electric arc furnace, where intense temperatures between 2000-2200°C (3632-3992°F) are generated by robust electric arcs to drive fusion.
Reduction and Fusion: Under these extreme conditions, alumina in the bauxite undergoes melting and reacts with anthracite carbon, forming molten alumina while impurities are efficiently reduced and segregated.
Cooling:
Cooling the Molten Alumina: The molten alumina is expertly poured into molds or onto a cooling floor, with precision-controlled cooling to ensure optimal crystal formation and size.
Formation of Ingots: As cooling progresses, the alumina solidifies into substantial ingots or blocks of high-quality fused alumina.
Crushing and Grinding:
Primary Crushing: The solidified ingots undergo initial breakdown via robust jaw crushers and heavy machinery, commencing the size reduction process.
Secondary Crushing and Grinding: Through cone crushers, roll crushers, and ball mills, the material is meticulously crushed and ground, achieving the precise particle size necessary for excellence.
Magnetic Separation:
Removing Metallic Impurities: Advanced magnetic separators ensure thorough removal of residual iron and metallic impurities, maintaining product purity.
Sieving and Classification:
Particle Size Distribution: The refined alumina is expertly sieved into diverse grades based on particle size, employing state-of-the-art vibrating screens and air classifiers.
Quality Control: Every batch undergoes rigorous testing for chemical composition, particle size distribution, and other quality metrics to assure adherence to industry standards.
Dive into the versatile world of White Fused Alumina (WFA), engineered to cater to an extensive array of industrial applications. The particle size of WFA plays a pivotal role in its performance, hence selecting the right size is essential for optimal results. Explore the typical sizes available for White Fused Alumina:
