Introduction
This wood pellet production line is exported to Croatia. Since customer want to expand the capacity in future, thus he purchased two sets wood pellet machines ( HSKLN-E350 ). Customer's raw material is wood chips, hammer mill is suitable for crushing it into sawdust. Due to raw material humidity is a little high, we recommended our double stoves hot air dryer machine for customer using. This wood pellet production line includes hammer mill, double stoves hot air dryer, wood pellets machines ( with screw feeder ), cooler, conveyors, and electric cabinet. It is highly automated.
Applicable raw material condition
- Any agro-forestry waste can be used
- Raw material diameter should be less than 5mm
- Humidity should be less than 20%
- Need not use binder. Ligin is a good adhesive.
Our service
1. One year's guarantee completely
2. Accept testing machines before delivery
3. Online technical supporting 24 hours
4. We could based on customer's raw material and factory size to design most suitable production line for using.
Complete Pellet production line 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 have a moisture content of about 50%. However, the optimal moisture content for pelletiztion is 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.
