Raw Material Preparation:
Bauxite: This remarkable journey begins with the careful selection of pristine bauxite, a raw material rich in alumina (Al2O3). Our commitment to quality ensures each batch contains the perfect alumina percentage, free from unwanted impurities.
Iron Filings or Scrap Iron: A strategic addition of iron filings or scrap iron elevates the fusion process by facilitating the reduction phase, thus enhancing the overall product integrity.
Anthracite Coal: A pivotal reducing agent, anthracite coal plays an essential role in refining the fusion process, offering unmatched precision.
Fusion:
Electric Arc Furnace (EAF): The concoction of expertly prepared materials is introduced into a state-of-the-art electric arc furnace. Here, electric arcs between carbon electrodes generate immense temperatures, ranging from 2000-2200°C (3632-3992°F), setting the stage for a superior fusion.
Reduction and Fusion: Within this thermally charged environment, the alumina in bauxite gracefully melts and interacts with the carbon from anthracite, forming a pure, molten alumina. Simultaneously, impurities, including iron, are seamlessly reduced and separated, refining the product's quality.
Cooling:
Cooling the Molten Alumina: The molten treasure is then skillfully poured into molds or onto specialized cooling floors. This controlled cooling process is vital to sculpt the desired crystal structure and size, ensuring exceptional performance.
Formation of Ingots: As the cooling magic unfolds, the material solidifies into formidable ingots or blocks, each a testament to the artistry of fused alumina production.
Crushing and Grinding:
Primary Crushing: The mighty ingots cool and are led through jaw crushers, where they begin their transformation with precision and power.
Secondary Crushing and Grinding: Further refining takes place as the material undergoes secondary crushing and grinding. Utilizing cone crushers, roll crushers, and ball mills, this meticulous process continues until the perfect particle size is achieved.
Magnetic Separation:
Removing Metallic Impurities: The refined material is then channeled through magnetic separators, ensuring the meticulous removal of residual iron particles and metallic impurities, thereby preserving the purity of the final product.
Sieving and Classification:
Particle Size Distribution: The meticulously crushed and purified alumina is then expertly sieved into various grades. This is achieved through the harmonic dance of vibrating screens and air classifiers, resulting in a product tailored to specific applications.
Quality Control: Each glorious batch undergoes rigorous testing to guarantee it meets the highest industry standards. Our assessments encompass chemical composition, particle size distribution, and a suite of quality parameters, confirming an unsurpassed product.
Discover the versatility of White Fused Alumina (WFA), available in a diverse array of sizes tailored to meet the unique demands of a broad spectrum of industrial applications. The meticulous selection of WFA particle sizes is crucial, as it greatly influences performance and effectiveness. Delve into the typical range of sizes that WFA offers for unparalleled results in your specific applications:
