4-5T/H Wood Pellet Plant

Complete wood pellet production line is designed for industrial production to make biomass pellets from any type of agro and forestry wastes with output from 1 ton to 10 ton per hour. The finished wood pellets are widely used for heating purposes of industrial boilers and large power plants as well as home use to alleviate the energy crisis and meet eco-friendly requirements.

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 complete wood pellet production line

 . 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 20hours.              

. 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.
 

Process of Complete Wood Pellet Production Line

Raw materials Preparation
Wood pellets can be made from sawdust, wood shavings, wood chips or wood logs, any forestry wastes or biomass straws, stalks, etc.

Raw Material Crushing Process
Crushing machine is used for crushing the larger materials into smaller powder for supporting produce wood pellets. Wood crusher is ideal equipment for crushing raw materials like square logs with diameter less than 200mm; if the material has a diameter less than 50mm, then wood hammer mill is the best choice. The best thickness of the wood chip is less 5mm. After milled, the output size can reach diameter 3-5 mm,which is convenient for further processing to get dried and pelletized.

Biomass Material Drying Process
The best moisture content to pelletizing is about 11-17%. So before pelletizing, a drying machine is needed to make the moisture content reaches the required standards.

Wood Pelletizing Process
Pellet mill is the significant part of the wood pellet production line, and has reliable and stable performance. Capacity ranges from 1T to 10T per hour. You can choosering die pellet mill or flat die pellet mill depend on your capacity requirements.


Wood Pellet Cooling Process
After pelletizing process, the temperature of wood pellets is between 60-80 degrees and the moisture content is close to 15%. So a cooler must be used to reduce their surface temperature and the moisture content which makes the wood pellets easy to store, meanwhile helps screen good and pure pellets.

After the cooling process, packing proces
