1. Raw Material Preparation:
Bauxite: At the heart of our process lies high-quality bauxite, chosen meticulously for its rich alumina concentration (Al2O3) and minimal impurities, setting the foundation for superior product excellence.
Iron Filings or Scrap Iron: These elements are skillfully blended to enhance the reduction during the fusion phase, ensuring optimal results.
Anthracite Coal: This crucial component acts as a powerful reducing agent, driving the transformation process.
2. Fusion:
Electric Arc Furnace (EAF): Our cutting-edge EAF reaches scorching temperatures of 2000-2200°C (3632-3992°F), employing electric arcs between carbon electrodes to expertly handle the prepared mixture.
Reduction and Fusion: In this high-temperature environment, alumina from the bauxite melts, interacting with anthracite carbon to form pure molten alumina, while impurities like iron are effectively reduced and removed.
3. Cooling:
Cooling the Molten Alumina: The molten alumina is expertly cast into molds or onto a cooling floor, where controlled cooling is paramount to achieving the desired crystalline structure and optimal size.
Formation of Ingots: As it cools, the material transforms into impressive ingots or substantial blocks of fused alumina, ready for the next stage.
4. Crushing and Grinding:
Primary Crushing: Robust machinery including jaw crushers is used to initially break down the cooled ingots, paving the way for finer processing.
Secondary Crushing and Grinding: Utilizing cone crushers, roll crushers, and ball mills, the material is finely crushed and ground to achieve the precise particle size required.
5. Magnetic Separation:
Elimination of Metallic Impurities: Advanced magnetic separators are employed to thoroughly cleanse the material of any residual iron particles and other unwanted metallic elements.
6. Sieving and Classification:
Particle Size Distribution: Through precise sieving via vibrating screens and air classifiers, the alumina is sorted into distinct grades, ensuring the perfect particle size distribution for varied applications.
7. Quality Control: Stringent testing for chemical composition, particle size distribution, and a suite of quality parameters is conducted on each batch, guaranteeing alignment with strict industry standards and delivering unmatched product quality.
Our White Fused Alumina (WFA) presents a versatile range of sizes, tailored to meet the intricate demands of a spectrum of industrial applications.
