Furnace for Drying and Firing Iron Ore Pellets

A laboratory roasting furnace is designed for drying and firing iron ore pellets as part of research into iron and steel production processes using the pelletizing method.

The development of pelletizing (pellet production) is driven by the declining share of rich iron ore deposits and the predominance of ores with low iron content. In such ores, iron is often present in the form of fine-grained inclusions.

The role of drying and firing in pellet preparation

Drying removes free and hygroscopic moisture, preventing pellet cracking during subsequent heating.

Firing (at temperatures of 1200-1350°C) ensures:

• Increased mechanical strength due to particle sintering;
• Improved chemical stability (oxidation of FeO to Fe₂O₃);
• Removal of volatile impurities (S, CO₂).

Finished pellets are used in blast furnaces or direct iron reduction.

Advantages of use

A laboratory furnace for drying and firing iron ore pellets allows precise research into pelletizing processes, contributing to the optimization of technological processes in the metallurgical industry and improving the quality of finished products.
