Raw Material Preparation:
Bauxite: At the core of our production is bauxite, rich in alumina (Al2O3). We meticulously select bauxite to assure high alumina content and minimal impurities, forming the foundation of unsurpassed quality.
Iron filings or scrap iron: These are integrated into the mixture, playing a pivotal role in enhancing the reduction process during fusion, ensuring a superior product.
Anthracite coal: This essential component acts as a potent reducing agent, critical to achieving optimal fusion.
Fusion:
Electric Arc Furnace (EAF): Our expertly prepared mixture is introduced into an electric arc furnace. Here, immense temperatures (2000-2200°C or 3632-3992°F) are achieved via electric arcs between carbon electrodes, setting the stage for transformation.
Reduction and Fusion: Under these intense conditions, alumina in bauxite liquefies and reacts with anthracite's carbon, yielding molten alumina. Concurrently, impurities are reduced and effectively separated.
Cooling:
Cooling the Molten Alumina: This molten alumina is skillfully poured from the furnace into molds or onto cooling floors. Controlled cooling is paramount, ensuring the perfect crystal structure and size.
Formation of Ingots: As cooling progresses, the material solidifies into substantial ingots or blocks, representing the fused alumina ready for the next stage.
Crushing and Grinding:
Primary Crushing: Post-cooling, the ingots are initially fragmented using robust jaw crushers or similar heavy machinery.
Secondary Crushing and Grinding: The material undergoes further crushing and grinding, utilizing cone crushers, roll crushers, and ball mills, until the ideal particle size is attained.
Magnetic Separation:
Removing Metallic Impurities: Through advanced magnetic separators, the ground material is cleansed of any residual iron particles and other metallic impurities, ensuring purity.
Sieving and Classification:
Particle Size Distribution: The refined alumina is meticulously sieved into various grades by particle size, utilizing vibrating screens and air classifiers, guaranteeing precise classification.
Quality Control: Every batch undergoes rigorous testing for chemical composition, particle size distribution, and other key quality parameters, ensuring adherence to the highest industry standards.
White fused alumina (WFA) comes in a diverse array of sizes, tailored to meet the varying demands of numerous industrial applications. The performance of WFA is heavily influenced by particle size, making the selection of the correct size paramount for specific applications. Below, we present the standard particle sizes available for white fused alumina:
Macro Grit Sizes:
Coarse Grit: Spanning from F8 to F220 in accordance with FEPA standards.
Popular selections include F12, F24, F36, F46, F60, F80, F100, F120, F150, F180, and F220.
Applications: Ideal for heavy-duty grinding, cutting, and surface preparation tasks.
Micro Grit Sizes:
Fine Grit: Ranging from F230 to F1200, conforming to FEPA standards.
Widely used sizes include F240, F280, F320, F360, F400, F500, F600, F800, and F1000.
Applications: Perfect for precision grinding, lapping, and polishing activities.
Powder Form:
Ultra-fine powders, with particle sizes ranging from several microns to sub-micron scales.
Applications: High-precision polishing, crafting specialty ceramics, coatings, and functioning as a filler in various composite materials.
Choosing the Right Size:
Coarse Grit (F8 - F220): Apt for tasks demanding high material removal rates and vigorous surface preparation, such as grinding high carbon steel and robust polishing.
Medium to Fine Grit (F230 - F1200): Best for applications that balance material removal with surface finish quality, including fine grinding, lapping, and precision polishing.
Ultra-Fine Powder: Essential for achieving a flawless and exact finish in advanced ceramics production, high-performance coatings, and catalyst carrier creation.
Selecting the right size of white fused alumina is essential for unlocking optimal performance in your specific application. Whether your needs are coarse grit for intense grinding or ultra-fine powders for precision-focused tasks, white fused alumina offers a range of sizes to fulfill your requirements. Ensure superior outcomes by choosing the perfect size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory needs.
