Wood pellet mill production line

Wood pellet machine, also known as sawdust pellet machine, pellet mill, Granulator.

It is a machine that presses crushed trees, planks, bark, shavings, scraps of furniture factories and other raw materials into rod-shaped particles with a diameter of 6/8/10 mm through mechanical physical extrusion.


Wood pellet mill production line mainly includes 6 sections: Crushing section/Hammer section/Drying section/Pelletizing section/cooling section/packing section
Crushing section

Production Process


The wood chipper first crushes the waste wood into 3-5cm wood chips

Hammer section

Production Process


Crush 3-5cm wood chips into 3-5mm sawdust

Drying section

Production Process


Drying the moisture of the wood chips into 10-15% of moisture suitable for pelletizing

Pelletizing section

Production Process


The pelleting machine will make sawdust with appropriate size and moisture into 6/8/10mm pellets

Cooling section

Production Process


The temperature of the pellets just out of the pellet machine will be hot, need the cooler to cool the pellet. If you don’t use the cooler, you can choose to make a large silo for natural cooling

Packing section

Production Process


Pack the cooled pellets, the weight of the package can be changed according to your needs

The moisture content of scraps is less than


If moisture is higher, need to use dryer to reduce the water content before pelleting section.
