TERA BOND - IRON ORE PELLET GRADE
TERA BOND is an essential binding agent in iron ore pellet production. Its ability to absorb water and expand makes. it ideal for improving the quality of iron ore pellets. TERA BOND, with its higher swelling capacity, is particularly effective in this process,ensuring the production of durable and high-strength pellets.
Key Roles of TERA BOND in Iron Ore Pelletizing
- Binder for Mechanical Strength: TERA BOND acts as a binder, aiding in the agglomeration of fine iron ore particles. This ensures that the pellets are cohesive and strong enough to withstand the handling, transportation, and high-temperature smelting process.
- Swelling and Absorption Properties: TERA BOND high water absorption capacity allows it to rapidly bind iron ore fines, forming strong, durable pellets. This property also helps in controlling moisture content in green pellets, leading to improved pellet formation and better handling.
- Thermal Stability: During the high-temperature firing process, TERA BOND maintains its structural integrity, ensuring the pellets are resistant to bursting or breaking. This thermal stability is crucial for the longevity and quality of the final product.
- TERA BOND: Preferred for its high swelling capacity and superior binding properties, TERA BOND forms stronger, more cohesive pellets, which are essential in iron ore pelletizing.
TERA BOND
- High Plasticity: Allows for the easy formation of pellets under pressure.
- Cation Exchange Capacity (CEC): Enhances binding capabilities, ensuring tighter bonds between iron ore particles.
- Gel-like Structure: When hydrated, TERA BOND forms a gel-like structure, ensuring even distribution of moisture and binding agents throughout the pellet mixture.

- Increased Pellet Durability: TERA BOND improves the green strength (strength before firing) of the pellets, making them more resistant to handling and reducing material loss during transportation.
- Consistent Pellet Quality: TERA BOND helps achieve uniform pellet size and structure, ensuring that the pellets have consistent quality and can withstand the rigors of blast furnaces and direct reduction processes.
TERA BOND CRITI AL ADDITIVE
TERA BOND remains a critical additive in the iron ore pelletizing industry, ensuring that pellets maintain high quality, durability, and performance during the steelmaking process. Its unique properties—such as swelling capacity, thermal stability, and binding strength—make it indispensable for producing top-quality pellets suitable for blast furnace and direct reduction processes
IMPURITIES MINIMAL ADDITIVE
TERA BOND requires minimal addition, reducing the risk of impurities like silica in the pellets, thereby producing a purer iron content.
TERA BOND’s high efficiency as a binder reduces the overall binder consumption, leading to lower production costs while maintaining
high pellet quality.
Typical Dosage : 6.3–10 kg per ton of feed
TERA BOND NATURAL MATERIAL
As a natural material, TERA BOND offers an environmental friendly solution in pelletizing without affecting the metallurgical properties of iron ore.
TERA BOND HIGH IRON CONTENt
TERA BOND naturally contains a higher
percentage of iron, making it an ideal choice for producing pellets with maximum iron content. This ensures higher purity and superior performance in metallurgical processes.
