Composite pellet binder is a high-efficiency binder used in pellet ore production, designed to reduce solvent addition and improve the grade and strength of pellet ore. Here are some detailed information about composite pellet binder:
Composition and Structure
- Mainly composed of inorganic silicates and organic cellulose products, with necessary strengthening components added based on the particle size and composition of pellet ore.
Production Process
- Silicate crushing, grinding, artificial cultivation, drying, re-grinding, screening, mixing with organic strengthening agents, natural cultivation, and finally packaging.
Usage Method
- Dissolve the binder dry powder in water to form a colloid, then mix it with ore powder to effectively utilize its binding efficiency.
Performance Characteristics
- Low dosage: Generally around 1.5%.
- Easy to use: Dry powder is directly added and mixed with ore powder in the stirring bin.
- Environmentally friendly: Burns to produce carbon dioxide and water, leaving no residue.
- Good film-forming ability: Forms a smooth film on the surface of ore powder.
- High strength: The produced pellets exhibit high mechanical strength after drying.
Application Areas
- Primarily used in pellet ore production in the steel metallurgy industry, but also applicable in other pelletizing and granulation industries.
Development Trends
- High performance: Improve mechanical properties and functionality to meet production process requirements.
- Environmental sustainability: Develop solvent-free or low-pollution environmentally friendly binders.
- Scale and standardization: Adjust industrial structure to achieve large-scale reorganization and improve production efficiency and product quality.
In summary, composite pellet binder plays a crucial role in the steel metallurgy industry. With continuous technological advancements, its performance and application scope will be further enhanced.
