Pelletizing Binder

Pelletizing binder, also known as pellet adhesive, is an additive used in iron and steel metallurgical raw materials. Its main function is to bind finely ground ore particles into balls and improve the properties of wet, dry, and roasted pellets.
Common Pelletizing Binders
Bentonite
Main Components:
1. Montmorillonite group minerals.
Characteristics: High viscosity, adsorption, dispersibility, and expansibility.
Dosage: Generally 0.6%–0.8% abroad, while domestically it is usually 2%–3%, and can reach up to 5%.
2. Hydrated Lime
Main Components: Calcium hydroxide microparticles.
Characteristics: Small particle size, large specific surface area, good hydrophilicity, and cementing ability.
3. Peridur
Main Components: Cellulose-based natural polymer.
Characteristics: Non-toxic, free of elements harmful to the environment and smelting, improves green ball strength, and increases pellet porosity and reducibility.
4. Modified Starch
Main Components: Natural corn starch and cassava starch.
Characteristics: Wide applicability, strong binding force, stable quality, improves pellet formation rate and consolidation speed.
Applications
Metallurgical Industry: Used in the production of iron ore, manganese ore, and chromium ore pellets to enhance resource utilization and smelting efficiency.
Mining Industry: Used to produce various mineral powder sintered pellets as metallurgical raw materials.
Construction Industry: Used in the production of bricks, panels, and other building materials.
Agricultural Sector: Used as a carrier for organic fertilizers and pesticides to improve crop yield and quality.
