Lignosulfonate for Carbon Black & Coal Briquette Binder
Lignosulfonate binders help improve particle cohesion, pellet or briquette strength and handling performance in carbon black, coal and carbon material applications.
Functions
- Binder
- Pelletizing aid
- Particle cohesion support
- Dust reduction support
- Water-soluble process additive
Recommended Products
- Calcium Lignosulfonate
- Sodium Lignosulfonate
- Modified Lignosulfonates
Benefits
- Supports briquette and pellet strength
- Helps reduce fines during handling
- Provides cost-effective binding support
- Can support carbon material processing
Typical Dosage / Technical Notes
Dosage depends on particle size, moisture, pressing conditions and required final strength.
How it works in practice
Fine carbon black, coal and coke are hard to handle as dust. Granulating or briquetting them needs a binder that wets the particles and holds them together after drying. Lignosulfonates are widely used for this because they dissolve in water, coat fine particles and form a strong film when dried. Calcium grades are common in briquettes; sodium grades dissolve faster.
- Carbon black pelleting: binder in wet pelletising to reduce dust and improve handling.
- Coal and coke fines briquettes: binder for green and dried strength.
- Charcoal and biomass briquettes: binder alternative to starch or molasses.
Choosing a grade
| Product | Typical role |
|---|---|
| Calcium lignosulfonate | Briquette binder for coal, coke and charcoal fines |
| Sodium lignosulfonate binder grade | Fast-dissolving binder for pelletising |
| Dispersant NNO | Dispersing carbon black in slurries |
Trial checklist
- Green strength and dried strength (drop and crush tests)
- Water resistance of finished briquettes
- Ash and sulfur added by the binder for your end use
- Binder dose against cost per tonne of briquettes
FAQ
Can lignosulfonate be used as a briquette binder?
Yes. Lignosulfonates are used as binders in briquetting and pelletizing applications where grade selection is important.
Which grade is commonly considered?
Calcium lignosulfonate and sodium lignosulfonate are commonly reviewed for binder applications.
What materials are commonly bound with lignosulfonate?
Coal fines, carbon black, graphite-related powders and other mineral or carbon-rich particles are commonly reviewed for binder-supported pelletizing or briquetting.
What production details matter before testing a binder grade?
Particle size, moisture, target crush strength, binder dosage range, pressing method and post-drying conditions all affect binder selection and trial performance.
