Introduction A Wood Project: 10-12 Ton Per Hour Wood Pellet Production Line

Oct 27, 2017

Flowchart of wood pellet making line

The wood pellet production line includes wood chipping, wood crushing (if the raw material is not ready for granulated), material sieving, drying (if the raw material contains too much moisture), wood pellets pelletizing, cooling, screening and packing.

Main process of wood pellet plant:

Crushing process - wood chipper and wood hammer mill

The best material size for supporting to produce pellet is 1-5mm. Thus if your material diameter exceed 5mm, then you need crushing machine to crush and grind them into small powder 1-5mm. Our LYGX series wood chipper and MFSP series hammer mill are your best choice. After milled, the output size can reach 3-5 mm, then it is pushed to next processto get dried and pelletized.

Drying process - Rotary Dryer

The best moisture content to pelletizing is about 12-18%. Our rotary dryer is made up of burning stove and main rotary dryer which is high efficient in drying the wood and biomass material. It can realize to reduce the moisture from 50% to 10%.It is very important for wood pellet plant to using moisture detector which will determine the most suitable moisture before pelletizing.

Pelletizing process - Wood pellet mill

Wood pellet mill is the heart of the wood pellet production line, and has reliable running performance. It is special designed for compacting of wood, straw, and other biomass sources into pellets. Capacity ranges from 1T to 10T per hour. Our MZLH series Ring die pellet mill is best choice for large scale production.

Cooling process - Counterflow cooler

Usually after pelletizing, the temperature of wood pellets is between 60-80 degrees and the moisture content is close to 15%. For storage purposes,a cooler must beused to reduce their surface temperature and the moisture content, also help screen good and pure pellets. 

Packing process - Packing machine

After cooling process, the wood pellets will not directly enter into the fuel process, avoiding the wood pellet affected with damp, the packing process is very necessary. The packing process is effectively handled by our Semi-Auto Packing Machine.

Please kindly note: Not all these processes are necessary for you. These are common processes for your reference. we will customize the complete solution as per your raw materials condition and your request for capacity.
