What is a wood pellet line?


wood pellet line comprise the process of turning waste materials into valuable solid fuels through pellet production. The primary use of wood pellets is burning in various components such as grills, house heaters, and furnaces. Among the most prominent pelletizing materials is wood pellet. It can come from multiple sources, including agricultural waste such as sawdust sugarcane biogases, sunflower stalks, wood chips, rice husks, and tobacco waste.

What is the process involved in the wood pellet line?

The wood pellet line comprises five key processes: crushing, drying, pelletizing, cooling, and packing. To successfully go through these processes, you need to have the right equipment and raw materials. Furthermore, the necessary conditions are also crucial for producing high-quality wood pellets.


Crushing involves reducing the materials’ sizes with the help of a wood chipper hammer mill. The wood chipper chips and crushes the materials into small pieces ready for drying. The result of the crushing process is a wood powder and may also be referred to as sawdust.

Suppose you have materials such as logs. In that case, you may consider removing the barks first. Afterward, you can take the logs through the same process as the other materials. Most importantly, you should have the right equipment to process various materials for making wood pellets.


The ideal moisture content when pelleting is 12-15%. Some dryers are built to reduce the moisture content of materials by a significant margin. You may use barks and other waste woods to fuel your stove to produce the required amount of hot air.

It would be best to pay reasonable attention to energy saving during the drying process. You might use and waste a lot of energy at this stage if you are not careful. So, using the waste wood produced during the pelleting process might be a great idea to save energy.


The pelletizing process works across three main systems: the lubrication system, driving gear, the die, and the roller. Some wood pellet machines have a computer-controlled lubrication system controlled by a microcomputer. The driving gear’s primary function is to allow various transmissions while the machine operates. So too, the ring die is the last in the pellet making chain and helps produce the wood pellets where they are transferred to the cooling section.


High-temperature wood pellets ranging between 60 and 80 degrees are transferred from the ring die with a 15% moisture content. The cooling process is essential for easy packaging of the finished wood pellets.


The wood pellet line ends with the packing process done after cooling. Here you may get proper packaging bags carrying a specific amount of wood pellets. The weight will depend on your specifications as an individual or a company.

It is important to note that dust filtering is a critical procedure during wood pellet production. You should therefore have the right equipment to collect dust from the material. During cooling and drying, the dust collectors help reduce dust generation.
