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.
Sawdust briquette machine is a kind of screw extrusion type press. Also known as: biomass ball making machine and charcoal machine. It is used to make biomass raw material into fuel type balls. Sawdust briquette machine can take waste agricultural materials to produce wood briquette. Thereby carbonising the biomass into charcoal. Wood chips made into fuel have higher density and calorific value compared to natural wood. The burning time is longer.
Sawdust briquette machine is used to produce charcoal Raw materials include: wood shavings, rice husk, straw, twigs, bamboo, coffee grounds, coconut shells, peanut shells and so on. It contains a certain amount of lignin. Lignin is an important ingredient of coal stick moulding. In the high temperature and high pressure plasticising moulding. Lignin can re-form the shape of briquette.
Biomass feedstock size and humidity are important for the production and processing of high quality charcoal. The raw material needs to be crushed into powder or granules of <5mm by a wood crusher. The raw material is then dried in a sawdust dryer. The moisture content is less than 10%.
Firstly, set the temperature of the sawdust pelletising machine at: 280°C. When the temperature reaches 280℃. The treated biomass feedstock can be fed to the sawdust ball making machine. With the rotating screw forward to the end of the equipment mill. Under the action of high temperature and high pressure, plasticising and moulding. Shape the sawdust powder into wood briquette. Eventually discharged from the grinding tool. It should be noted that the temperature needs to be adjusted according to different raw materials. So as to obtain higher quality charcoal.
The shape and size of the pellets produced by the briquette machine are determined by the grinding cylinder. The diameter of the pellets produced by the briquette machine is: 500mm, 70mm.
| Model | Power | Capacity | Sawdust briquette diameter | Sawdust briquette shape |
| VT-200 | 11kw | 200kg/h-300kg/h | 50mm | Hexagonal and Square |
| VT-300 | 18.5kw | 300kg/h-400kg/h | 50mm/70mm | Hexagonal and Square |
| VT-500 | 22kw | 400kg/h-500kg/h | 50mm/70mm | Hexagonal and Square |

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.
