Raw Material Preparation:
Bauxite: As the cornerstone of our production, this exceptional raw material is imbued with a superior concentration of alumina (Al2O3). Each batch of bauxite is meticulously curated to guarantee optimal alumina levels and minimal impurities, ensuring unparalleled quality.
Iron filings or scrap iron: These materials are strategically incorporated into the mixture to facilitate the reduction process during the fusion stage, enhancing the overall efficiency and quality.
Anthracite coal: Serving as a potent reducing agent, anthracite coal plays a pivotal role in the transformation process.
Fusion:
Electric Arc Furnace (EAF): Our expertly prepared mixture is introduced into a state-of-the-art electric arc furnace. This furnace harnesses the power of electric arcs, producing intense heat levels (approximately 2000-2200°C or 3632-3992°F) that are essential for the process.
Reduction and Fusion: At these searing temperatures, bauxite's alumina content melts, engaging in a reaction with anthracite's carbon to yield molten alumina. Concurrently, iron and other impurities undergo reduction and separation, achieving a refined state.
Cooling:
Cooling the Molten Alumina: The molten alumina is carefully transferred from the furnace into molds or onto a cooling floor. Precision in cooling is critical, as it determines the ultimate crystal structure and size, vital for the product's excellence.
Formation of Ingots: Upon cooling, the material solidifies into substantial ingots or blocks of fused alumina, primed for the next stage.
Crushing and Grinding:
Primary Crushing: The solidified ingots undergo an initial breakdown using robust jaw crushers and heavy-duty machinery, setting the stage for further refinement.
Secondary Crushing and Grinding: The material is meticulously crushed and ground into finer particles using advanced cone crushers, roll crushers, and ball mills. This precise process continues until the desired particle size is achieved, ensuring consistency and quality.
Magnetic Separation:
Removing Metallic Impurities: To ensure the purity of the product, the ground material is expertly passed through magnetic separators, eradicating any lingering iron particles and other metallic impurities.
Sieving and Classification:
Particle Size Distribution: The crushed and purified alumina is then subjected to a meticulous sieving process, categorizing it into various grades based on particle size. This is expertly executed using vibrating screens and air classifiers, ensuring a product that meets the highest standards.
Quality Control: Each meticulously crafted batch undergoes rigorous testing for chemical composition, particle size distribution, and a suite of other quality parameters, ensuring compliance with stringent industry standards and guaranteeing customer satisfaction.
White fused alumina (WFA) is a versatile abrasive material available in an extensive array of sizes, meticulously designed to cater to the varied demands of diverse industrial applications. The performance of WFA particles is deeply influenced by their size, making it imperative to select the optimal size tailored for specific uses. Presented below are the typical sizes in which white fused alumina is offered:
Macro Grit Sizes:
Coarse Grit: Spanning from F8 to F220 (FEPA standard), these sizes are the cornerstone for numerous industrial needs.
The most commonly utilized sizes include F12, F24, F36, F46, F60, F80, F100, F120, F150, F180, and F220, each meeting unique requirements.
Applications: Engineered for heavy-duty grinding, cutting, and robust surface preparation tasks.
Micro Grit Sizes:
Fine Grit: Extending from F230 to F1200 (FEPA standard), these sizes are perfect for intricate tasks.
Among the popular sizes are F240, F280, F320, F360, F400, F500, F600, F800, and F1000, each crafted for specific high-precision applications.
Applications: Ideally suited for precision grinding, detailed lapping, and meticulous polishing.
Powder Form:
Ultra-fine powders, with particle sizes from mere microns to sub-micron levels, offer exceptional finesse.
Applications: Designed for high-precision polishing, advanced specialty ceramics, innovative coatings, and as a filler in cutting-edge composite materials.
Choosing the Right Size:
Coarse Grit (F8 - F220): The go-to choice for applications that demand high material removal rates and assertive surface preparation. Perfect for grinding high carbon steel and intensive polishing tasks.
Medium to Fine Grit (F230 - F1200): The ideal choice for applications seeking a harmonious balance between material removal and impeccable surface finish quality, such as fine grinding, lapping, and precision polishing.
Ultra-Fine Powder: The ultimate choice for applications requiring an unmatched smooth and precise finish, as seen in the production of advanced ceramics, high-performance coatings, and catalyst carriers.
Selecting the precise size of white fused alumina is paramount to achieving optimal performance tailored to your specific application. Whether your requirement is for coarse grit for heavy-duty grinding or ultra-fine powders for high-precision tasks, white fused alumina is available in a comprehensive range of sizes to meet your diverse needs. Achieve unparalleled results by selecting the ideal size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory application.
