What’s sawdust briquette machine
Sawdust briquette machine is a screw-type extruder for producing briquettes as fuel from biomass materials. It is one of the important machines in making bio charcoal briquettes. So it is also called a wood charcoal machine.
Why make wood sawdust briquettes
- Wood sawdust briquettes can be used as fuel for burning directly. Compare with natural wood, it has a higher density and heating value.
- Wood charcoal machine can use wood waste and agro-waste to produce briquettes. It changes the traditional way of making charcoal from the wood log, helping us reduce the tree felling.
- Compare with natural timber charcoal, sawdust briquettes charcoal has a higher heating value and longer burning time.
Materials for making briquettes
Materials for producing biomass briquettes can be wood sawdust, rice husk, tree branches, coconut shell, bagasse, peanut shell, bamboo, and etc. One thing in common of these materials is that they all contain a certain amount of lignin. Lignin is an important ingredient for briquetting, it can reform the shape in the condition of high pressure and high temperature.
Material size and moisture
The size and moisture of materials are important for making high-quality wood briquettes. Regarding the size of the material, it needs to be less than 3mm, and the moisture content should be less than 12%. sometimes, we will need a wood crusher and sawdust dryer to help us process the raw materials.
How to make wood briquettes
First, we set the temperature to 300℃. After the temperature rises to 300℃, we begin to feed materials. Sawdust is pushed by the rotating screw forward to the end of the mold. Under high temperature and high pressure, sawdust is forming into briquettes and expelled out from the mold.

Sawdust briquette shape & size
The shape and size of briquettes are determined by the mold cyclinder. Diameter of briquettes can be 50mm, 70mm and 80mm. All the briquettes have a hollow in the centre of cross section. People usually further convert the wood briquettes to charcoal briquettes by the carbonzation furnace to gain more profits.
Spare parts of wood briquette machine
Spare parts of the wood log maker machine include a screw propeller, heating ring, and mold cylinder.
About the service life of these spare parts, our suggestions are as below,
screw propeller: We suggest check the screw propeller per week and welding repair its head if necessary. For one year of production, at least 6pcs screw propellers.
Heating ring: Suppose that 24 working hours per day, the service life of the heating circle is about 6 months.
Mold cylinder: Suppose that 24 working hours per day, the service life of mold cover is about 3 months.
