With the growing demand for renewable energy, recycling waste wood into biomass fuel pellets has become an effective way to improve wood resource utilization and reduce material waste.
In Indonesia, BISON MACHINE designed a 6–8 TPH biomass pellet production line to convert waste wood into high-quality biomass fuel pellets.
Considering the characteristics of waste wood materials, this production line adopts a multi-stage crushing and drying configuration. The raw materials are first processed by a wood chipper, followed by initial crushing, drying, secondary crushing, pelletizing, cooling, and packaging.
Two hammer mills are installed at different positions to handle material size reduction before and after drying, ensuring suitable material conditions for subsequent pellet production.

The Wood Chipper is the first major processing machine in this production line. It is used to cut large waste wood materials into smaller wood chips with a size below 30 mm.
Through mechanical cutting, the Wood Chipper reduces the original size of waste wood, making the material easier to convey and process. This initial size reduction prepares the raw materials for the subsequent hammer mill and provides suitable material for further crushing.
As the starting equipment of the production line, the wood chipper plays an important role in waste wood processing and supports the continuous operation of downstream equipment.
After chipping, the wood chips are conveyed to the first Hammer Mill for further crushing. This machine processes the wood chips into particles smaller than 20 mm through hammering and crushing.
The initial crushing process further reduces material size after wood chipping, preparing the waste wood for the subsequent drying process. By providing more suitably sized material, the first hammer mill helps establish a consistent material flow into the rotary dryer.
The Rotary Dryer is an essential piece of equipment for controlling the moisture content of waste wood before pelletizing.
After initial crushing, the material enters the rotary dryer for continuous drying. During operation, the material moves through the rotating drum and undergoes moisture reduction. The drying process reduces the material moisture content to approximately 10–15%, preparing it for the subsequent secondary crushing and pelletizing stages.
In this production line, the rotary dryer is positioned between the two hammer mills, allowing the material to undergo initial crushing before drying and further size reduction after drying.
After drying, the material enters the second Hammer Mill for secondary crushing. Unlike the first hammer mill, which processes the wood chips before drying, this machine handles the dried material before pelletizing.
The secondary crushing process further refines the dried material and improves particle uniformity. This helps provide more consistent raw material for the XGJ850 pellet machines and supports stable pellet formation.
By installing two hammer mills at different processing stages, the production line can handle both initial size reduction and post-drying material refinement more effectively.
The XGJ850 Pellet Machine is the core forming equipment in this production line. This Indonesian project is equipped with two XGJ850 pellet machines, each with a production capacity of approximately 3–4 TPH.
After secondary crushing, the prepared waste wood material is conveyed through a hydraulic bin before entering the pellet machines. The hydraulic bin provides temporary material storage and coordinates feeding to the pelletizing section.
Under the pressure of the pelletizing system, the processed wood material is compressed into compact biomass fuel pellets. With two XGJ850 pellet machines working together, the production line achieves its designed capacity of 6–8 TPH.
Freshly produced biomass pellets have a relatively high temperature and need to be cooled before packaging. The Series Cooler is installed after the pellet machines to reduce the temperature of the newly formed pellets.
During cooling, the pellets gradually release heat and become more stable for subsequent handling, storage, and transportation. This equipment provides the necessary cooling treatment before the finished pellets enter the packaging section.
After cooling, the finished biomass pellets enter the packaging section. The Jumbo Bag Packaging Machine is used to pack the pellets into jumbo bags, making bulk collection, handling, and transportation more convenient.
Depending on the customer's packaging requirements, the finished pellets can also be packed in 25 kg bags. These two packaging options provide flexibility for different storage, transportation, and sales needs.
This 6–8 TPH biomass pellet production line in Indonesia integrates multiple types of equipment to convert waste wood into finished biomass fuel pellets.
The Wood Chipper cuts large waste wood into chips below 30 mm. The first Hammer Mill further crushes the material to below 20 mm before it enters the Rotary Dryer, where moisture is reduced to approximately 10–15%. After drying, the second Hammer Mill performs secondary crushing to improve material uniformity. Two XGJ850 Pellet Machines then compress the processed material into biomass pellets, followed by cooling and final packaging.
