Production Process

Raw Material Preparation:
Bauxite: The primary raw material is bauxite, which contains a high percentage of alumina (Al2O3). The bauxite is carefully selected to ensure the desired alumina content and minimal impurities.
Iron filings or scrap iron: Added to the mixture to aid in the reduction process during fusion.
Anthracite coal: Used as a reducing agent.

Fusion:
Electric Arc Furnace (EAF): The prepared mixture is fed into an electric arc furnace. The furnace generates high temperatures (around 2000-2200°C or 3632-3992°F) through electric arcs struck between carbon electrodes.
Reduction and Fusion: At these high temperatures, the alumina in bauxite melts and reacts with the carbon from anthracite to produce molten alumina. Iron and other impurities are reduced and separated.

Cooling:
Cooling the Molten Alumina: The molten alumina is poured out of the furnace into molds or onto a cooling floor. Controlled cooling is crucial to achieve the desired crystal structure and size.
Formation of Ingots: As the material cools, it solidifies into large ingots or blocks of fused alumina.

Crushing and Grinding:
Primary Crushing: The cooled ingots are first broken down using jaw crushers or other heavy machinery.
Secondary Crushing and Grinding: The material is further crushed and ground into smaller sizes using cone crushers, roll crushers, and ball mills. This process continues until the desired particle size is achieved.

Magnetic Separation:
Removing Metallic Impurities: The ground material is passed through magnetic separators to remove any remaining iron particles and other metallic impurities.
Sieving and Classification:

Particle Size Distribution: The crushed and cleaned alumina is then sieved into different grades based on particle size. This is done using vibrating screens and air classifiers.

Quality Control: Each batch is tested for chemical composition, particle size distribution, and other quality parameters to ensure it meets industry standards.
