Organic Binders for Iron Ore Pellets

Jianjie’s organic binders for iron ore pellets excel in pelletizing iron ore concentrates, including magnetite and hematite powders, producing high-quality pellets, delivering high pellet strength, improved metallurgical performance, and lower impurities. With lower dosage requirements and eco-friendly formulation, it helps pellet plants cut costs while supporting cleaner, more sustainable ironmaking.

Range of Applications

Jianjie binder for iron ore pellets are used in various iron ore concentrates:

  • Magnetite powder
  • Hematite powder
  • Limonite powder
fired iron ore pellets

Advantages of Jianjie Organic Binder

Outstanding Pelletizing Performance
  • A forming rate of 98%
  • Green pellets remain intact after more than 7 drops from 0.5m
  • Dry pellets reach 50–100N compressive strength
  • Roasted pellets exceed 2500N after firing at 1200℃ for 25 minutes.
Proven Economic Benefits
  • By reducing bentonite addition by ↓1.0%
  • pellet grade improves by ↑0.6%
  • 1.8% increase in blast furnace output
  • a ↓1.2% reduction in coke consumption

Reduce Bentonite Use

Jianjie organic binder effectively reduces or partially replaces bentonite in iron ore pellet production. By lowering bentonite dosage, the binder helps increase the Fe content of pellets, improve metallurgical performance, and reduce ash introduction.

Reduce SiO2 and Al2O3

Reduce the dosage of bentonite to lower silicon dioxide (SiO2) and aluminumoxide (Al2O3) content, while improving the total iron (TFe) grade in pellets.

No Phosphorus (P) or Sulfur (S)

Free of phosphorus and sulfur, ensuring cleaner pellet chemistryand meeting strict metallurgical requirements.

Maintain Cold Compressive Strength (CCS)

Does not affect green pellet burst temperature, while maintaining the cold compressive strength of pellets after roasting.

Increase Wet Compressive Strength (WCS)

Increases the durability of wet pellets, reducing breakage during drop tests.

Increase porosity

Boosts porosity to improve the reducibility of pellets during furnace operations.

Increase capacity

Enhances material feeding speed and pellet forming rate, significantly boosting overall production capacity.

Protected by IP Rights (IIPRs)

The company’s products are backed by over 20 patents and more than 40 independentintellectual property rights, ensuring innovation and quality assurance.

Jianjie Organic Binders VS. Bentonite

Below compares iron ore pellet performance using different Jianjie’s organic binders versus traditional bentonite binder, focusing on how Jianjie organic binders affect the use of bentonite, the compressive and drop strength throughout pellet production.

1.4% Bentonite Alone

❌ Weak Performance

  • Strength: 2446.9 N roasted pellets
  • High dosage required (1.4%)
  • Weak durability and higher cost

Jianjie Binder 1 + Bentonite

✅ Good CCS

  • Just 0.06–0.1% dosage with 1% bentonite
  • Roasted pellet Strength: Up to 3150.9 N
  • +29% stronger than bentonite alone

Jianjie Binder 2 + Bentonite

💰 Cost-Efficient

  • Bentonite reduced from 1.4% → 0.7%
  • Only 0.05% Jianjie binder needed
  • Still achieves 2560.3 N strength
  • Balance of cost & quality

Jianjie Binder 3 + Bentonite

🔄 Reliable Performance

  • Dosage: ~0.9% bentonite + ~0.1% binder
  • Roasted pellet strength: 2600–2700 N
  • Consistent, stable results for varied applications

*The above test results are based on specific laboratory conditions; results may vary under different experimental setups.
