Raw Material Preparation:
Bauxite: Our production journey begins with meticulously chosen bauxite, renowned for its high alumina (Al2O3) content. This selection process ensures minimal impurities and the highest quality standards in our final product.
Iron filings or scrap iron: These are incorporated into the mixture, playing a vital role in facilitating the reduction process during the fusion stage.
Anthracite coal: This crucial component acts as a reducing agent, ensuring optimal fusion and quality.
Fusion:
Electric Arc Furnace (EAF): Our expertly prepared mixture is introduced into the state-of-the-art electric arc furnace, where temperatures soar to an impressive 2000-2200°C (3632-3992°F), courtesy of powerful electric arcs between carbon electrodes.
Reduction and Fusion: At these extreme temperatures, bauxite's alumina melts and engages in a chemical dance with anthracite's carbon, producing pure molten alumina while impurities like iron are effectively reduced and separated.
Cooling:
Cooling the Molten Alumina: The molten marvel is skillfully transferred from the furnace into molds or spread across a cooling floor. This carefully controlled cooling process is key to attaining the perfect crystal structure and size.
Formation of Ingots: As the material embarks on its cooling journey, it solidifies into majestic ingots or blocks of pristine fused alumina.
Crushing and Grinding:
Primary Crushing: The formidable cooled ingots meet their match as they're expertly broken down using advanced jaw crushers and heavy-duty machinery.
Secondary Crushing and Grinding: The refinement continues with cone crushers, roll crushers, and ball mills, meticulously grinding the material to the precise particle size desired.
Magnetic Separation:
Removing Metallic Impurities: Magnetic separators come into play, efficiently purging the ground material of any lingering iron particles and metallic impurities.
Sieving and Classification:
Particle Size Distribution: The purified alumina is expertly sieved into a spectrum of grades based on particle size, through the use of sophisticated vibrating screens and air classifiers.
Quality Control: Every batch undergoes rigorous testing for chemical composition and particle size distribution, ensuring that our product consistently meets and exceeds the industry's highest standards.
Experience the exceptional versatility of our White Fused Alumina (WFA), available in an extensive range of sizes designed to cater to the diverse requirements of various industrial applications.
