Raw Material Preparation:
Bauxite: The journey begins with bauxite, a remarkable raw material, rich in alumina (Al2O3). Each batch is meticulously chosen for its superior alumina content and minimal impurities, ensuring a high-caliber final product.
Iron filings or scrap iron: Incorporated into the blend, these materials play a pivotal role in enhancing the reduction process during fusion, contributing to the overall quality of the final product.
Anthracite coal: Employed as a powerful reducing agent, anthracite coal is essential for facilitating key reactions within the fusion phase.
Fusion:
Electric Arc Furnace (EAF): The meticulously prepared mixture takes center stage in an Electric Arc Furnace. This furnace, with its awe-inspiring temperatures ranging from 2000-2200°C (3632-3992°F), unleashes electric arcs between carbon electrodes to achieve optimal fusion.
Reduction and Fusion: At these intense temperatures, the bauxite's alumina melts and engages with the carbon from anthracite, giving rise to molten alumina. Concurrently, iron and other impurities are effectively reduced and separated, ensuring purity.
Cooling:
Cooling the Molten Alumina: The transformation continues as molten alumina is strategically poured into molds or onto cooling floors. This step is crucial, with controlled cooling techniques employed to craft the desired crystal structure and particle size.
Formation of Ingots: As cooling ensues, the material solidifies into formidable ingots or blocks of fused alumina, ready for the next phase of production.
Crushing and Grinding:
Primary Crushing: These formidable ingots undergo an initial breakdown via robust jaw crushers or equivalent machinery, paving the way for further refinement.
Secondary Crushing and Grinding: Precision continues as the material undergoes further crushing and grinding, utilizing cone crushers, roll crushers, and ball mills, until the exact particle size is achieved, tailored to industry needs.
Magnetic Separation:
Removing Metallic Impurities: To ensure uncompromised quality, the ground material is subjected to magnetic separators, effectively eliminating residual iron particles and other metallic impurities.
Sieving and Classification:
Particle Size Distribution: Post-cleaning, the alumina is meticulously sieved into diverse grades, categorized by particle size. This is achieved through state-of-the-art vibrating screens and air classifiers, ensuring precision and uniformity.
Quality Control: Every batch undergoes rigorous testing for chemical composition, particle size distribution, and other critical quality parameters, guaranteeing adherence to stringent industry standards and ensuring unparalleled excellence.
White fused alumina (WFA) is a versatile abrasive media tailored to cater to the diverse spectrum of industrial applications. With a wide array of particle sizes available, selecting the perfect size is pivotal for maximizing performance. Each size variation exhibits unique characteristics that enhance specific uses. Below are the typical white fused alumina sizes:
Macro Grit Sizes:
Coarse Grit: Spanning from F8 to F220, adhering to the FEPA standard, tailored for robust applications.
Common coarse sizes include F12, F24, F36, F46, F60, F80, F100, F120, F150, F180, and F220.
Applications: Ideal for heavy-duty grinding, cutting, and thorough surface preparation.
Micro Grit Sizes:
Fine Grit: Ranging from F230 to F1200 (FEPA standard), crafted for finesse and precision.
Common fine sizes include F240, F280, F320, F360, F400, F500, F600, F800, and F1000.
Applications: Perfect for precision grinding, meticulous lapping, and flawless polishing.
Powder Form:
Ultra-fine powders with particle sizes from mere microns to sub-micron levels, offering unparalleled precision.
Applications: Suited for high-precision polishing, specialty ceramics production, coatings, and as a superior filler in composite materials.
Choosing the Right Size:
Coarse Grit (F8 - F220): Optimal for scenarios demanding high material removal rates and intensive surface preparation tasks like grinding high carbon steel and heavy-duty polishing.
Medium to Fine Grit (F230 - F1200): Tailored for applications where a harmonious blend of material removal and surface finish quality is crucial, such as fine grinding, precise lapping, and meticulous polishing.
Ultra-Fine Powder: Exquisite choice for applications necessitating an exceptionally smooth and precise finish, ideal for advanced ceramics production, high-performance coatings, and catalyst carriers.
Choosing the right white fused alumina size is essential to achieving optimal performance in your particular application. Whether it's coarse grit for robust grinding or ultra-fine powder for precision tasks, white fused alumina is available in a multitude of sizes to fulfill your requirements. Ensure superior results by selecting the perfect size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory needs.
