A complete wood pellets pelletizing plant, from raw material processing to final pellet packing, can be general divided into the following three parts:

1.Material handling system( wood chipper & wood crusher)
As there are various kinds of raw material for making wood pellets, you should have a clear understanding about them.Materials with different size and diameter need to be handled with different machines. Wood crusher and wood hammer mill are both available to process wood materials.
Wood crusher is ideal equipment for crushing raw materials like square logs with diameter less than 200mm; if the material& acute;s diameter is less than 50mm,wood hammer mill is the best choice. The output of both two machines has a diameter about 4mm which is suitable for pelletizing process.

2.Pelletizing system(drying & wood pelletizing machine)
The wood powder produced by wood crusher and hammer mill has too much moisture which can effect the quality of pellets. So before pelletizing, a wood drying machine is needed to make the moisture reaches about 15%. According to the wood powder moisture and handling capacity, you should choose the most suitable one from drum dryer and pipe dryer.
Pellet mill is the heart of the whole pellet plant. Ring die wood pellet mill and flat die wood pellet mill are the two popular machines respectively for large and small wood pellet production scale.

3.Packing system(cooling, screening& pellets bagging machine)
After the pelletizing process, the temperature of the wood pellet is more than 80 degree centigrade, and the moisture content of the wood pellet is about 15%.So we need use a cooler to reduce about 3-4% of the moisture, which makes the wood pellet easy to store. A pellet cooler is necessary to cool down wood pellets temperature and lower down their moisture content for easy storage.
