Alumina Steel Silo for Efficient Storage and Handling
Alumina steel silo is engineered for safe, efficient, and continuous storage of alumina powder in alumina refineries and electrolytic aluminum plants.
Product Overview
The Alumina steel silo is engineered for safe, efficient, and continuous storage of alumina powder in alumina refineries and electrolytic aluminum plants. After roasting and cooling in the calcination furnace, alumina is transported via air chute and bucket elevator into large-capacity silos. The stored material is then discharged for bulk truck loading or ton-bag packaging, ensuring smooth logistics and stable production flow.
Application Scope
In alumina refineries, storage capacity typically ranges from 5,000 to 30,000 tons. In electrolytic aluminum plants, fresh alumina is stored in bulk or bagged form, then pneumatically conveyed to fresh alumina silos or fluorine-loaded alumina silos. Standard storage capacity in electrolysis workshops is around 2,000 tons per silo, supporting continuous feeding for electrolysis cells.
Material Handling Process
Fresh alumina is discharged from silos and transported through sealed air chutes to flue gas purification systems, where fluorine absorption occurs. The material is then converted into fluorine-loaded alumina and re-conveyed to dedicated silos before being fed into electrolytic cells for aluminum production.
Product Features of Mineral Powder Steel Silos
The Alumina steel silo is designed with advanced structural modeling and engineering calculations to ensure long-term safety under varying load conditions. Different silo structures are selected based on application requirements to guarantee operational stability.
All steel surfaces are shot blasted and coated according to ISO anti-corrosion standards, providing excellent durability in harsh industrial environments. The sealed structure ensures dust-free operation, preventing material leakage and environmental contamination.
Performance Advantages
The silo offers excellent sealing performance, long service life, and stable discharge efficiency. Its modular steel structure enables fast installation, reducing construction time and overall investment cost while maintaining high operational reliability.
Advanced Engineering Solutions
To solve common issues such as long-distance conveying, material blockage, and overflow of alumina powder, the system integrates sealed chute technology, intelligent material conveying detection, and unmanned control systems. These innovations significantly improve conveying efficiency and reduce manual intervention.
Conclusion
The Alumina steel silo provides a reliable, efficient, and cost-effective storage solution for alumina powder handling across refinery and electrolytic aluminum production processes, ensuring continuous, safe, and automated material flow throughout the production chain.

Oxygen Rich Side Blown Melt Melting Furnace
Contact UsThe oxygen rich side blown molten pool melting furnace is an efficient and energy-saving steel melting equipment. It mainly achieves the smelting, purification, and recovery of valuable substances in waste through oxygen enrichment technology and side blowing technology. Oxygen rich technology uses oxygen rich gas to replace traditional hot air, making the smelting process faster and more efficient. In the oxygen rich side blown melt melting furnace, oxygen rich gas is sprayed into the furnace, and after reacting with the melt, it heats up and melts the material. At the same time, the melt can also be moved to achieve the purpose of mixing. Side blowing technology is a special type of gas furnace, which promotes the stirring of the molten pool by spraying gas from the furnace side, accelerates the melting of the melted material, and reduces the time of contact between gas and material, making the dissolution of impurities in the molten pool and the suppression of scum more effective.
