High Capacity Wood Pellet Turn-key Project

Introduce of Wood Pellet Turn-key Project:

1)Our wood pellet mill machine absorbs the quintessence of various wood pellet mill both at home and abroad,the heart part adopts " ring die"as the unique structure. The rollers are made by abrasion -proof alloy steel,our wood pellet machine with characteristics of unique design, rational structure,low power consumption,high long lifetime.

2)Our wood pellet mill machine is applied to the material with low adhesiveness and lowshaping (raw material),such as the rice husk,sunflower seed husk,peanut shell and other fruit shell branch,trunk,bark and other wood waste;a variety of crop straws, rubber,cement,ash and other chemical materials.


Raw material of Wood Pellet Turn-key Project

Sawdust ,wood logs, wood chips, waste wood, bark, straw ,wheat straw ,rice husk, cotton stalk,coconut slag, sunflower stalk, olive slag, grassiness, bamboo, bagasse, paper, cassava, EFB, peanut shell ,corn cob, soybean stalk, weed, wood branches, leaves and so on.

Wood Pellet Turn-key Project process:

(a)Peeling Process

  

Wood debarker machine is applicable to peel the log of MDF board and papermaking industry, it is mainly used to peel log, small wood and so on, the peeled rate is more than 95 percent.

 

(b)Chipping Process

 

In the pellet plant before raw materials are made into biomass pellets, they are 

first reduced into much smaller, uniformly-sized particles. When the thicknedd is larger than 10mm or the size is greater than 50*50mm, a chippper is needed to chip these materials into smaller pieces.

 

(c)Grinding Process

 

The hammer mill is used to further crush these small pieces into particles of less than 3mm in diameter.

 

 

(d)Drying Process

 After raw materials are crushed a dryer is needed since most raw wood materials havea moisture content of about 50%. However, the optimal moisture content for pelletiztionis 13%-15%. Therefore a rotary dryer is included in the pellet plant to reduce the moisture content. After crushing and drying you can begin making wood pellets.

 


(e)Pelletizing Process

 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 pellet plant. It should be mentioned that impurities in the raw materials 

like metal or stone,may damage the die and rollers of pellet making machine.

 

 

(f)Cooling Process

 Usually after pelletizing, the temperature of pellets is between 60-80 degrees and the moisture content is close to 15%. For storage purpose, a cooler must be used to reduce their surface temperature and moisture content.

 

(g)Packing Process

 Finally is the packing process. In order to protect the wood pellets becoming getting 

damp and to increase storability, proper packing is necessary.
