Raw Material Preparation:
Bauxite: Our process begins with the selection of premium bauxite, a raw material rich in alumina (Al2O3). We meticulously choose bauxite that guarantees the optimal alumina composition, ensuring minimal impurities for the highest quality outcome.
Iron filings or scrap iron: These are incorporated into the blend to facilitate an efficient reduction process during the fusion stage, enhancing overall product quality.
Anthracite coal: Utilized as a potent reducing agent, anthracite coal is essential for driving the fusion process forward efficiently.
Fusion:
Electric Arc Furnace (EAF): We employ state-of-the-art electric arc furnaces, where the carefully prepared mixture is subjected to intense temperatures between 2000-2200°C (3632-3992°F), achieved via electric arcs from carbon electrodes.
Reduction and Fusion: In this fiery environment, bauxite alumina liquefies and interacts with anthracite carbon, forming molten alumina. Concurrently, iron and other impurities are reduced and meticulously isolated.
Cooling:
Cooling the Molten Alumina: Once molten, the alumina is strategically poured into molds or onto cooling floors. This controlled cooling is vital to cultivate the desired crystal structure and size, pivotal to our product's excellence.
Formation of Ingots: Upon cooling, the material solidifies into impressive ingots or blocks of fused alumina, setting the stage for further processing.
Crushing and Grinding:
Primary Crushing: The robust ingots are initially fragmented using jaw crushers or other robust machinery, breaking them down efficiently.
Secondary Crushing and Grinding: The material is subsequently further crushed and refined into finer particles through the use of cone crushers, roll crushers, and ball mills, ensuring the desired particle size is finely achieved.
Magnetic Separation:
Removing Metallic Impurities: Our process incorporates advanced magnetic separators that meticulously extract remaining iron particles and other metallic impurities, ensuring product purity.
Sieving and Classification:
Particle Size Distribution: The refined alumina is systematically sieved into various grades according to particle size, utilizing sophisticated vibrating screens and air classifiers.
Quality Control: Every batch undergoes rigorous testing for chemical composition, particle size distribution, and other quality parameters, ensuring compliance with industry standards and our commitment to excellence.
White fused alumina (WFA) is meticulously crafted to cater to the extensive demands of various industrial sectors, available in an array of sizes that ensure optimal performance. The particle size of WFA is a crucial factor influencing its efficiency, demanding careful selection tailored to your specific application. Below you will find the range of common sizes available for white fused alumina:
Macro Grit Sizes:
Coarse Grit: Spanning from F8 to F220, following the esteemed FEPA standard.
Popular choices include sizes such as F12, F24, F36, F46, F60, F80, F100, F120, F150, F180, and F220.
Applications: Ideal for intensive tasks like heavy-duty grinding, cutting, and preparing surfaces.
Micro Grit Sizes:
Fine Grit: Extending from F230 to F1200, aligned with the FEPA standard.
Widely used sizes include F240, F280, F320, F360, F400, F500, F600, F800, and F1000.
Applications: Perfect for precision tasks such as grinding, lapping, and achieving a polished finish.
Powder Form:
Ultra-fine powders with particle dimensions ranging from mere microns to even sub-micron levels.
Applications: Designed for high-precision polishing, specialized ceramics, innovative coatings, and as a filler in diverse composite materials.
Choosing the Right Size:
Coarse Grit (F8 - F220): Best suited for scenarios requiring accelerated material removal rates and robust surface preparation, like grinding high carbon steel and extensive polishing tasks.
Medium to Fine Grit (F230 - F1200): Ideal for balancing material removal with superior surface finish quality, perfect for fine grinding, lapping, and precision-oriented polishing tasks.
Ultra-Fine Powder: Essential for applications demanding unparalleled smoothness and precision, such as advanced ceramics production, high-performance coatings, and catalyst carrier manufacturing.
Selecting the perfect white fused alumina size is vital to unlocking peak performance in your application. Whether you aim for coarse grit for heavy-duty grinding or ultra-fine powders for precision tasks, white fused alumina provides a comprehensive size range to meet your unique requirements. For exceptional results, ensure you choose the right size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory endeavor.
