Wood Pellet Plant

Product Description

Wood pellet plant is the whole process of wood pellet making, including the grinding system, pelleting system, cooling system and packing system. 

Wood pellet production line with a capacity of **4t/h

Working Process
1.Chipping and Crushing
In the wood pellet plant before raw materials are made into biomass pellets, they are first reduced into much smaller, uniformly-sized particles. When the thickness is larger than *0 mm or size is greater than *0**0 mm, a wood chipper is needed to chip these materials into smaller pieces. The hammer mill is then used to further crush these small pieces into particles of less than 3 mm in diameter. 
 2. Drying
 After raw materials are crushed a dryer is needed since most raw wood materials have a moisture content of about *0%. However, the optimal moisture content for pelletiztion is *3%**5%. Therefore a rotary dryer is included in the wood pellet plant to reduce the moisture content. After crushing and drying you can begin making wood pellets.
3. Pelletizing
After crushing and drying the raw material properly it is then ready for the pellet mill. The pelletizing machine or press is the key piece of machinery in the wood pellet plant.
* It should be mentioned that impurities in the raw materials like metal or stone,may damage the die and rollers of  wood pellet making machine.  
4. Cooling
Usually after pelletizing, the temperature of wood pellets is between ****0 degrees and the moisture content is close to *5%. For storage purposes, a cooler must be used to reduce their surface temperature and moisture content. 
5. Packing
Finally is the packing process. In order to protect the wood pellets becoming getting damp and to increase storability, proper packing is necessary. Here we provide you with the best domestic Semi-Auto Packing Machine.
