Comprehensive Guide to Raw Material Formulation for Smokeless Charcoal Briquettes

Producing export-grade Chinese charcoal briquettes requires a strict scientific balance between natural lignin, fiber moisture, and carbon concentration. Here is the verified industrial formula developed by Komur Machine engineers.

1. The Golden Briquetting Formula:

• Softwood Poplar Sawdust: 60% - 65% (Provides thermal binding via natural lignin melt)
• Graded Walnut Shell Powder (Mesh 30): 15% - 20% (Maximizes density, eliminates sparks, extends burn past 4 hours)
• Pistachio Shells or Fine Carbon: 10% - 15% (Ensures clean white ash residue)

2. Moisture Sensitivity:

Feedstock moisture entering the extruder screw must be maintained precisely between 7% and 10%. Higher moisture induces vapor blowouts, while drier feedstock accelerates barrel wear.
