Wood/sawdust/rice Husk Pellet Production Line With 2.5-3.5t/h Capacity
The Requirement of Raw Material
Size:10mm below(All the raw materials must be crushed into sawdust before going to
wood pellet machine.If not, you may need a wood chipper, wood crusher.)
Moisture: Generally, 10-15% is best for producing good quality wood pellet.
If too high, or too low, you need to dry or moisture them first.
Pellet production process:
Hammer mill crushing, rotary dryer drying, pellet mill pelletizing, cooler cooling, packing machine packing
Features of wood pellet mill machine
as core machine of whole wood pellet production line, there are our innovations:
. Ring die( mould) , vertical structure, granulating chamber cooling.Material feed directly in pellet forming chamber.Die static, two rollers rotating, and material centrifugal with big torque force.
. Double layers ring die , down & up dual-use, low cost, high efficiency and energy saving.Wood pellet making machine main heart parts--die adopt high alloy wear resistant material, the service life of wearing parts is two times than similar products.
. Fully automatic lubrication pump,you just add enough high temperature oil,then it lubricate the bearing of two roller and main shaft automatically with timming time,make sure the sawdust pellet machine can work continuously more than 20 hours.
. Frequency adjusted feeding screw conveyor or belt conveyor,make sure the material can feed in time by adjust the speed of screw conveyor motor ,so make sure the high capacity.
. Our wood pellet making machine with accuracy gear reducer drive ,make sure the ring die wood pellet machine work more efficiency and stable.
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.
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.
The hammer mill is used to further crush these small pieces into particles of less than 3mm in diameter.
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.
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.
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.
Finally is the packing process. In order to protect the wood pellets becoming getting
damp and to increase storability, proper packing is necessary.
According to your raw material’s shape, size, moisture content:
