From sawdust to charcoal: two efficient production methods and steps in detail

With the focus on sustainability and the growing demand for biomass energy, the process of converting sawdust into high-quality charcoal is becoming increasingly important.

Our charcoal machine system provides an efficient solution for sawdust to charcoal, helping customers to achieve effective resource utilization through two different production processes: carbonisation → moulding and biomass briquettes making → charring.

Method 1: First carbonization and then moudling

Step 1: Crushing wood waste

Crush various waste wood, such as wood brancehs, segements, trimmings, etc. into sawdust.

Step 2: Drying sawdust

Because there is a requiremnt of sawdust waster content, the sawdust dryer is used in this process.

Step 2: Carbonizing wood sawdust

Then, use the continous charcoal furnace to convert the sawdust into semi-finished charcoal powder.

Step 3: Molding sawdust charcoal to briquettes

Mix carbonised charcoal powder is mixed with suitable binder to increase the strength of the moulding. Then use the charcoal making machine to press and mould carbon powder into desried shapes.

Method 2: First sawdust briquettes making and then carbonization

Step 1: Crushing waste wood

Firstly, crush all kinds of waste wood.

Sep 2: Drying sawdust

The wood chips or sawdust are then dried to achieve a standard moisture content suitable for pressing.

Step 3: Making biomass briquettes

Using wood sawdust briquettes machine to press the dried wood chips into biomass fuel rods (i.e. biomass pellets or lumps). During this process, no need additive.

Step 4: Carbonizing sawdust briquettes

Finally, the shaped wood chip biomass fuel rods are placed in a carbonisation furnace for high-temperature carbonisation (commonly used vertical carbonisation furnace and horizontal carbonisation furnace), so that they are converted into high-quality charcoal products.
