Sawdust is produced in large quantities every day in some wood processing plants. If it is sold directly to someone, the price per tonne may be in the tens of dollars. However, if the sawdust is processed into charcoal sticks using a charcoal making machine, the value is much higher. It can also be made into barbecue charcoal, hookah charcoal, honeycomb briquettes and so on. The price per tonne is as much as: several hundred US dollars. Sawdust can be converted into high quality charcoal by pyrolysis technology. Waste treatment in the wood processing industry provides an effective charcoal making solution. This charcoal is widely used in industry, agriculture and other industry sectors.
So, how is sawdust made into charcoal briquettes? According to different sawdust processing process is different. It can be divided into making rods first and then carbonising, carbonising first and then making rods.
Carbonisation before briquette: if you only use sawdust to make charcoal, there is no large lumpy waste that can be directly carbonised. If it is a large piece of material such as trimmings, waste and so on. Then you need to use a crusher. According to different sizes of wood waste crushed into sawdust. According to the moisture content of the sawdust. If in some processed wood is dry wood, sawdust has no moisture. This kind of material can be directly used in the carbonisation furnace carbonisation. If it is a wetter material. Sawdust moisture is large, you need to use a drum dryer or natural drying first. After drying, the sawdust is sent to the carbonisation furnace through a conveyor. The carbonisation process takes about 30 minutes. The continuous carbonisation furnace can be operated in a continuous mode with constant carbonisation. The feeding and discharging is continuous. The sawdust is carbonised. The sawdust is then fully mixed and combined using a carbon powder mixer and binder. The final product is made into finished charcoal using a sawdust briquette machine.
Briquette before carbonisation: Sawdust with high moisture content needs to be dried in a drum dryer. Moisture control: 8-10%. Then use the briquette machine to form the rods. The formed charcoal sticks are then carbonised at a high temperature using a carbonisation furnace (horizontal carbonisation furnace, hanging carbonisation furnace). The final product is sawdust charcoal.

Sawdust briquette machine utilises raw materials such as sawdust, crops, straw, bagasse and so on. After crushing, the raw materials are processed into hollow bar body in high temperature and high pressure area.
Charcoal Briquette Extruder Machine is also called coal stick extruder. Adopting the principle of spiral extrusion. It is a coal bar moulding equipment that compresses the modulated coal powder into a prefabricated shape with a certain strength.
Bamboo chips are the main raw material. After drying in the drying machine, the material is dry and wet properly. After cooling, the material passes through the bamboo charcoal machine. After high temperature, high pressure and plasticisation.
Continuous carbonisation furnace is a new type of charcoal production equipment. He can be used to produce large-scale rice husk charcoal, sawdust charcoal, coconut shell charcoal, nut shells and so on. Through the oxygen-free carbonisation and dry distil
Horizontal Carbonisation Furnace Also known as charcoal making machine. It can carbonise all kinds of raw materials. The equipment adopts new high temperature dry distillation pyrolysis carbonisation technology.
Vertical lifting carbonisation furnace is using advanced airflow carbonisation. It can produce all kinds of biomass charcoal. The carbonisation furnace has convenient operation, environmental protection and energy saving, high production efficiency...
Sawdust dryer refers to put the powder granular wet sawdust. After high temperature hot airflow conveying and dispersing. So that the moisture in the material is evaporated.
The air flow dryer is widely used for drying powder-like material. The humidity can be controlled at 10-16%. It is a kind of high efficient, continuous and fast solid fluidised drying method.
