Choosing a suitable BBQ charcoal binder is not only about comparing binder prices or dosage. The final briquette strength depends on the complete production process.
Before selecting a binder, charcoal manufacturers should check the following five factors.
1. Charcoal Particle Size
Particle size directly affects briquette density and bonding. If the charcoal powder is too coarse, the briquette may contain weak areas and break easily.
2. Moisture Content
Correct moisture helps the powder form under pressure.
Too little water may cause poor forming and cracks.
Too much water may cause sticking, deformation and longer drying time.
3. Binder Dosage
Using too little binder may result in weak briquettes. However, adding excessive binder can increase production cost and may change the finished briquette formulation.
The dosage should be confirmed by production testing.
4. Briquette Machine Pressure
The same binder formula can produce different results on different machines. Pressing pressure, feeding stability and mold condition should be checked during testing.
5. Required Briquette Strength
BBQ charcoal for long-distance transportation normally requires better handling strength than charcoal used near the production plant.
Recommended Testing Method
Record the following information during each test:
binder dosage + water addition + mixing time + machine pressure + drying conditions + final strength
Changing only one factor at a time makes it easier to find the real cause of production problems.
