Raw Material Preparation:
Bauxite: The primary raw material, bauxite, is meticulously chosen for its high alumina (Al2O3) content and low levels of impurities. This careful selection ensures that only the best quality bauxite goes into the making of Advanced WFA white fused alumina.
Iron filings or scrap iron: These are vital components added to the mixture, playing a crucial role in the reduction process during the fusion stage. They assist in refining the molten alumina, eliminating unwanted impurities.
Anthracite coal: Serving as an essential reducing agent, anthracite coal facilitates the transformation needed to produce high-purity fused alumina.
Fusion:
Electric Arc Furnace (EAF): The carefully prepared mixture is introduced into a state-of-the-art electric arc furnace. Here, electric arcs between carbon electrodes generate intense heat, reaching temperatures of 2000-2200°C (3632-3992°F), necessary for the fusion process.
Reduction and Fusion: Under these extreme temperatures, the alumina in the bauxite melts and chemically interacts with the carbon from anthracite. This results in the creation of molten alumina while simultaneously reducing and separating iron and other impurities, ensuring the purity of the alumina.
Cooling:
Cooling the Molten Alumina: Once the fusion is complete, the molten alumina is carefully poured into molds or allowed to cool on specialized floors. The controlled cooling process is instrumental in forming the preferred crystal structure and particle size.
Formation of Ingots: As cooling progresses, the material solidifies into substantial ingots or blocks of premium fused alumina.
Crushing and Grinding:
Primary Crushing: The solidified ingots undergo initial breakdown through the use of jaw crushers or equivalent heavy-duty machinery, setting the stage for further processing.
Secondary Crushing and Grinding: The material is subsequently reduced to finer sizes via cone crushers, roll crushers, and ball mills. This step is meticulously executed to achieve the precise particle size desired.
Magnetic Separation:
Removing Metallic Impurities: Utilizing advanced magnetic separators, the processed material is thoroughly passed through to eradicate any lingering iron particles and other metallic impurities, ensuring a high purity product.
Sieving and Classification:
Particle Size Distribution: The crushed and refined alumina is systematically sieved and classified into various grades based on particle size. This task is expertly performed using vibrating screens and air classifiers to ensure consistency and quality.
Quality Control: Every batch of fused alumina is subjected to rigorous testing. It is scrutinized for chemical composition, particle size distribution, and a suite of other quality parameters to ascertain that it adheres to stringent industry standards.
White fused alumina (WFA) boasts an extensive spectrum of size options, catering to the multifaceted demands across various industrial sectors. The particle size plays a pivotal role in enhancing performance, making it imperative to choose the optimal size tailored to the specific application requirements. Discover the typical size options available for your white fused alumina needs:

Choosing the Right Size:
Coarse Grit (F8 - F220): Best suited for scenarios necessitating extensive material removal and aggressive surface preparation, such as grinding high carbon steel and conducting heavy-duty polishing.
Medium to Fine Grit (F230 - F1200): Perfectly suited for applications that require a delicate balance between material removal and attaining superior surface finish, such as fine grinding, lapping, and precision polishing.
Ultra-Fine Powder: The ultimate choice for tasks demanding an exceptionally smooth and precise finish, such as manufacturing advanced ceramics, applying high-performance coatings, and developing catalyst carriers.
Selecting the ideal white fused alumina size is vital for attaining the optimal performance in your distinct application. Whether your need is for coarse grit to tackle heavy-duty grinding or ultra-fine powders for precision work, white fused alumina offers a diverse range of sizes designed to fulfill your requirements. Achieve unmatched results by selecting the perfect size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory applications.
