300-1000kg/h Wood Pellet Production Line


Complete Wood Pellet Production Line Process:


 Crushing Process---Drying Process---Pelletizing Process---Cooling Process---Packing Process



 1. Crushing Process:


 Depending on the different input material, we fit out the suitable Crushing machines. If the raw material is big logs , we need to split the log into small woods, and then are chipped into wood chips, our BX-Series Chipping and Crushing Machine is your best choices; While SFSW-series gear plate crusher is widely used to crush wood chips with high moisture into sawdust.

 2. Drying Process:


 The best moisture content to pelletizing is about 14-16%. Our new Air-Current Rotary Dryer is made up of Burning Stove and Main Rotary Dryer, which can realize to reduce the moisture from 50% to 10%, and save about 30% energy consumption comparing the old Rotary Dryer. Our burning stove is fueled by coal and wood material, which can save electricity consumption largely. If the users want to use the other fuel such as gas and electricity, one Burner is necessary, but the extra cost will be charged.
 3. Pelletizing Process:


 Wood Pellet Machine is the most important equipment, which have the following features:
 This equipment use sawdust, crops straw (corn stalk, beanstalk, sorghum culm and cotton stalk, rape stalk, sunflower culm and peanuts seedling), the chaff, grass, shrubs, twigs, bamboo sawdust, bag asse as raw materials, use this machine high temperature extrude into granules. Products are cylindrical.

 4. Cooling Process:


 After the pelletizing process, the temperature of the wood pellet is about 60-80 degree, and the moisture content of the wood pellet is about 15%, so we need use Cooler to reduce about 3-4% moisture, such this the wood pellet is easy to store. But considering the feedback from some foreign clients, the local climate is very humidity; They hope to cool the wood pellet with moisture 7-8%. In order to satisfy the different need from different clients, we develop one kind of new Stabilizer Combined Cooler.
 5. Packing Process:

 After cooling, the wood pellet will not directly enter into the fuel process, avoiding the wood pellet affected with damp. The packing process is necessary. In this process, we assemble our domestic best Semi-Auto Packing Machine to you.
