Production line and factory setup overview
A micro/small solid-fuel line making dense non-carbonized biomass briquettes from one locally available sawdust or crop-residue recipe through sorting, shredding or hammer milling, moisture conditioning, heated screw extrusion, controlled cooling, length cutting, strength and combustion checks and protected bundling or bagging. Carbonization into charcoal is excluded from this lowest-entry route.
Recommended lowest-entry line configuration Launch one 50-70 mm non-carbonized briquette from a naturally dry sawdust-rich feed at 150-300 kg/h. Use a magnet, small hammer mill, covered moisture-conditioning bin, one screw briquette extruder with spare screw and heating rings, cooling rack, cut-off saw, weighing and bundling. Exclude carbonization furnaces until fuel demand, smoke control, fire safety and environmental approval are proven.
Production process and implementation sequence
- Residue acceptance and sorting
- Size reduction and screening
- Moisture conditioning
- Heated screw extrusion
- Cooling and length cutting
- Crack/strength inspection
- Combustion trial and batch release
- Bundling or moisture-protected bagging
Products, capacity and market fit
- Low-density crop and wood residues are costly to transport without densification.
- A single extruder can support a workshop-scale entry.
- Non-carbonized briquettes avoid the cost and emissions of a charcoal furnace.
- Moisture, screw wear, briquette strength and buyer-stove trials control viability.
- Non-carbonized biomass fuel briquette - One diameter and feed recipe with moisture, density, drop strength, ash, smoke and calorific-value limits - Bakeries, boilers and institutional stoves after firing trial
