Raw Material Preparation: Crafting the Perfect Foundation
Bauxite Selection: Our journey begins with meticulously chosen bauxite, rich in alumina (Al2O3). Each piece is handpicked to guarantee the ideal alumina content and purity, ensuring exceptional quality.
Iron Infusion: Integrating iron filings or scrap iron into the mix, we enhance the reduction process during fusion, fortifying the core strength.
Anthracite Coal: The Unsung Hero, acting as a powerful reducing agent to enable flawless transformation.
Fusion: Where Raw Materials Transform into Excellence
Electric Arc Furnace: Here, the magic happens. This furnace, fueled by high temperatures (2000-2200°C or 3632-3992°F) created by electric arcs, transforms raw mixtures into pure molten greatness.
Reduction and Fusion: At this pinnacle of heat, alumina from bauxite merges with carbon from anthracite, resulting in molten alumina while impurities like iron are effortlessly reduced and separated.
Cooling: Sculpting Perfection through Temperature Control
Molten Alumina Mastery: The transition from liquid to solid is pivotal. Skillfully poured into molds or over cooling floors, controlled cooling defines the crystal structure and size to perfection.
Ingots Formation: Solidifying into robust blocks of fused alumina, ready for the next transformation.
Crushing and Grinding: Refining the Essence of Strength
Primary Crushing: Our journey continues as cooled ingots meet their match with jaw crushers, breaking down into manageable pieces.
Secondary Crushing and Grinding: A sophisticated process involving cone crushers, roll crushers, and ball mills, refining the material into precise particle sizes.
Magnetic Separation: Precision at Its Finest
Eliminating Metallic Intruders: Advanced magnetic separators ensure every trace of iron and metallic impurities vanishes, elevating the purity standard.
Sieving and Classification: Defining the Future
Particle Size Distribution: The pinnacle of precision! Our sieving process, aided by vibrating screens and air classifiers, segments alumina into diverse, application-specific grades. With each granule meticulously sorted, the versatile possibilities of our product shine through.
Quality Control: Excellence in Every Batch Every batch undergoes rigorous testing for chemical composition and particle size distribution, ensuring it aligns with the highest industry standards. This is our promise of unparalleled quality.
White Fused Alumina (WFA) is ingeniously crafted in an expansive spectrum of sizes, tailored to perfectly align with the myriad requirements of diverse industrial domains. The size of WFA particles is a vital determinant of their effectiveness, and selecting the right size is essential for achieving optimal results in specific applications.
