Raw Material Preparation:
Bauxite: Our carefully chosen bauxite acts as the core ingredient, rich in alumina (Al2O3). We meticulously select bauxite that boasts elevated alumina content with minimal impurities, ensuring optimal quality.
Iron filings or scrap iron: Infused into the blend to facilitate the reduction process during fusion, enhancing the overall reaction efficiency.
Anthracite coal: This vital component serves as a reducing agent, crucial for facilitating chemical reactions during fusion.
Fusion:
Electric Arc Furnace (EAF): Our prepared mixture journeys into the Electric Arc Furnace, where electric arcs between carbon electrodes ignite temperatures soaring to 2000-2200°C (3632-3992°F), creating the perfect environment for transformation.
Reduction and Fusion: In this intense heat, bauxite's alumina liquefies and mingles with the carbon from anthracite, yielding molten alumina, while iron and impurities are skillfully extracted and refined.
Cooling:
Cooling the Molten Alumina: The molten alumina cascades out of the furnace into molds or a cooling floor. This controlled cooling is essential for crafting the desired crystal structure and particle size.
Formation of Ingots: As the alumina cools, it solidifies into substantial ingots or blocks of pristine fused alumina, setting the stage for the next phase.
Crushing and Grinding:
Primary Crushing: Our robust jaw crushers or heavy machinery initiate the breakdown of the hardened ingots, spearheading the transformation process.
Secondary Crushing and Grinding: The material undergoes further disintegration and refinement using advanced cone crushers, roll crushers, and ball mills, tirelessly working to achieve the specific desired particle size.
Magnetic Separation:
Removing Metallic Impurities: High-efficiency magnetic separators cleanse the ground material, purging it of any lingering iron particles and other metallic impurities, ensuring purity.
Sieving and Classification:
Particle Size Distribution: The meticulously crushed and purified alumina is expertly sieved into distinct grades. Utilizing vibrating screens and air classifiers, we achieve precise particle size distribution to meet various industry demands.
Quality Control: Every batch undergoes stringent testing for chemical composition, particle size distribution, and other quality parameters, guaranteeing adherence to the highest industry standards.
White Fused Alumina (WFA) is engineered to perfection, available in a versatile array of sizes to meet the distinct demands of various industrial sectors. The particle size of WFA is pivotal to its performance, making the selection of the correct size essential for specific applications. Below is an outline of the typical sizes in which white fused alumina is offered, ensuring that every need is catered to with precision:
Macro Grit Sizes:
Coarse Grit: From F8 to F220 (in accordance with FEPA standards)
Commonly utilized sizes include F12, F24, F36, F46, F60, F80, F100, F120, F150, F180, and F220, each crafted for optimal performance.
Applications: Ideal for heavy-duty grinding, efficient cutting, and meticulous surface preparation.
Micro Grit Sizes:
Fine Grit: Spanning from F230 to F1200 (aligned with FEPA standards)
Popular sizes encompass F240, F280, F320, F360, F400, F500, F600, F800, and F1000, each ensuring precision in every task.
Applications: Perfect for precision grinding, expert lapping, and flawless polishing.
Powder Form:
Ultra-fine powders, designed with particle sizes ranging from mere microns to sub-micron levels, crafted for ultimate finesse.
Applications: Essential for high-precision polishing, the creation of specialty ceramics, intricate coatings, and as a filler in various advanced composite materials.
Choosing the Right Size:
Coarse Grit (F8 - F220): Best suited for tasks demanding high material removal rates and robust surface preparation, such as grinding high carbon steel and robust heavy-duty polishing.
Medium to Fine Grit (F230 - F1200): Perfectly balanced for applications that require a harmony between material removal and superior surface finish quality, like fine grinding, lapping, and precision polishing.
Ultra-Fine Powder: Ideal for applications necessitating a remarkably smooth and precise finish, such as in the creation of innovative ceramics, high-performance coatings, and catalyst carriers.
Selecting the appropriate size of white fused alumina is pivotal in achieving the desired performance for your specialized application. Whether your requirement is for coarse grit in heavy-duty grinding or ultra-fine powders for precision-focused tasks, white fused alumina is available in a comprehensive range of sizes to fulfill your needs. Assure optimal outcomes by choosing the ideal size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory application.
