Raw Material Preparation:
Bauxite: The primary raw material harnessed is bauxite, renowned for its high alumina (Al2O3) content. Meticulously chosen, the bauxite ensures optimal alumina levels while keeping impurities to a bare minimum.
Iron filings or scrap iron: Introduced strategically into the blend to facilitate the reduction process as fusion occurs.
Anthracite coal: A powerful reducing agent employed to enhance the process.
Fusion:
Electric Arc Furnace (EAF): The expertly prepared mixture enters the electric arc furnace, where soaring temperatures (approximately 2000-2200°C or 3632-3992°F) are achieved via electric arcs ignited between carbon electrodes.
Reduction and Fusion: Amidst these extreme temperatures, the alumina within the bauxite melts, interacting with the carbon from anthracite to create molten alumina, effectively reducing and separating iron and other impurities.
Cooling:
Cooling the Molten Alumina: The molten alumina is methodically transferred from the furnace into molds or onto a specialized cooling floor. This controlled cooling process is pivotal to attain the ideal crystal structure and size.
Formation of Ingots: As the cooling occurs, the material solidifies into substantial ingots or blocks, forming fused alumina.
Crushing and Grinding:
Primary Crushing: The substantial cooled ingots undergo an initial breakdown through jaw crushers or robust machinery.
Secondary Crushing and Grinding: The material is subjected to further crushing and grinding into finer dimensions using cone crushers, roll crushers, and ball mills, proceeding until the desired particle size is meticulously achieved.
Magnetic Separation:
Removing Metallic Impurities: The ground material passes through magnetic separators, efficiently extracting any residual iron particles and other metallic impurities.
Sieving and Classification:
Particle Size Distribution: The crushed and purified alumina is meticulously sieved into various grades dictated by particle size, employing advanced vibrating screens and air classifiers for precision.
Quality Control: Each batch is rigorously tested for chemical composition, particle size distribution, and a spectrum of quality parameters, ensuring adherence to stringent industry standards.
White fused alumina (WFA) is engineered to perfection, offering an extensive array of sizes designed to cater to the multifaceted requirements of various industrial applications. The optimal selection of particle size is paramount, as it directly influences the efficiency and results of your specific use-cases. Explore below the comprehensive sizes available for white fused alumina, tailored to enhance your operational excellence:
Macro Grit Sizes: For robust and demanding applications.
Coarse Grit: Spanning from F8 to F220 (FEPA standard), these grit sizes are devised to tackle the toughest challenges.
Common sizes encompass a diverse spectrum including F12, F24, F36, F46, F60, F80, F100, F120, F150, F180, and F220, each crafted to deliver exceptional performance.
Applications: Unleash the power of WFA for heavy-duty grinding, cutting, and surface preparation, ensuring superior outcomes with every use.
Micro Grit Sizes: Precision at its finest.
Fine Grit: Ranging from F230 to F1200 (FEPA standard), these sizes are engineered for precision work.
Common sizes include F240, F280, F320, F360, F400, F500, F600, F800, and F1000, each designed for meticulous precision and efficiency.
Applications: Perfect for precision grinding, lapping, and polishing tasks, offering unparalleled smoothness and accuracy.
Powder Form: Elevate your applications with ultra-fine precision.
Ultra-fine powders crafted with particle sizes extending from mere microns to sub-micron levels, ensuring the highest degree of refinement.
Applications: Ideal for high-precision polishing, specialty ceramics, coatings, and as an advanced filler in various composite materials, delivering exceptional quality.
Choosing the Right Size: Master the art of selection to maximize performance.
Coarse Grit (F8 - F220): Perfectly suited for applications requiring rapid material removal and aggressive surface preparation, such as grinding high carbon steel and executing heavy-duty polishing with finesse.
Medium to Fine Grit (F230 - F1200): Tailored for applications that demand a harmonious balance between material removal and superior surface finish quality, such as fine grinding, lapping, and precision polishing.
Ultra-Fine Powder: The ultimate choice for applications needing an exceptionally smooth and precise finish, ideal for producing advanced ceramics, high-performance coatings, and catalyst carriers.
Selecting the appropriate size of white fused alumina is pivotal for achieving the desired performance specific to your application. Whether your needs are for robust coarse grit for heavy-duty grinding or ultra-fine powders for precise applications, white fused alumina is available in a broad spectrum of sizes to satisfy your requirements. Ensure optimal results by choosing the correct size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory endeavors.
