2013 CE Wood Pellet Manufacturing Plant

Wood pellet production line is also known as wood pellet plant or pellet plant which serves for making the agro-forestry wastes into solid fuel or wood pellets. It includes crushing, drying, pelletizing, cooling, and packaging machinery.

Advantages of Wood Pellet Production Plant :

1. Environmental Friendly.
2. Easy to store and transport.
3. Wide application and good market.
4. Effective. Wood pellets generate high heat output.
5. The raw materials are available locally, sustainable and renewable.
6. Wood pellets cost is affordable and predictable. It is more stable than the ever-increasing price of fossil fuels.

Detailed Description of the Wood Pellet Manufacturing Plant

The Raw material of the Wood Pellet Production Plant :
Wood Pellets are mainly made from any wood waste and biomass particles, such as wood sawdust, wood shavings, wood chips, wood logs, straw, rice husk, coffee husk etc..
The Mainly Involved processes of Wood Pellet Production Plant :
Wood crushing (if the raw material is not already granulated), material sieving, drying (if the raw material contains too much moisture), pelletizing, cooling, screening and packing. The whole pelletizing process can be highly automatically controlled..
The Production capacity of the Wood Pellet Production Plant :
1 to 10 ton per hour is available.

Process of the Wood Pellet Manufacturing Plant

Our complete wood pellet plant has a compact structure, low energy consumption and is highly efficient. Every machine in the wood pellet plant can be designed and manufactured according to customers’ requirements. Professional technical guidance of installing the machinery is also available.The whole process of wood pellet line can be highly automatically controlled. It includes the below processes.

Crushing process – Hammer mill for the Wood Pellet Manufacturing Plant

The best material diameter for supporting to produce pellet is 1-5mm. Thus if your material diameter exceed 5mm, then you need crushing machine to crush and grind them into small powder 1-5mm for supporting to produce pellets.

Our SFSP series chipping and crushing machine is your best choice. It mills raw material like tree branch, wood shavings, wood chips, wood logs, cotton stalk, corn stalk, wheat straw etc, with size less than 50mm (diameter).

After milled, the output size can reach diameter 3-5 mm, then it is pushed to next process to get dried and pelletized.

Drying process – Rotary Dryer for the Wood Pellet Manufacturing Plant

The best moisture content to pelletizing is about 11-17%. Our rotary dryer is made up of burning stove and main rotary dryer which is high efficiency in drying the wood and

biomass material. It can realize to reduce the moisture from 50% to 10%.

The rotary dryer uses steam to heat air and contact material to remove certain degree of moisture. It is very important for wood pellet plant to using moisture detector which will determine the most suitable moisture before pelletizing.

Pelletizing process - Wood pellet mill for the Wood Pellet Manufacturing Plant Pellet mill is the heart of the wood pellet production line, and has reliable running performance . It is special designed for compacting of wood, straw, and other biomass sources

into pellets. Capacity ranges from 1T to 10T per hour.

You can choose ring die pellet mill or flat die pellet mill depend on your capacity requirement. Our MZLH series Ring die pellet mill is best choice for large scale production, while, AMSPLM series flat

die pellet mill is suitable for small pellet production line. Please feel free to contact us for more information.

Cooling process - Pellet cooling machine for the Wood Pellet Manufacturing Plant

Usually after pelletizing, the temperature of wood pellets is between 60-80 degrees and the moisture content is close to 15%. For storage purposes, a cooler must be used to reduce their surface temperature and the moisture content, also help screen good and pure pellets.
However, considering the feedback from some foreign clients, the local climate is very humidity, they hope to cool the wood pellets with moisture 7-8%. In order to satisfy different needs from different clients, we develop one kind of new Stabilizer Combined Cooler.

Packing process - Pellet packing machine for the Wood Pellet Manufacturing Plant

After cooling process, the wood pellets will not directly enter into the fuel process, avoiding the wood pellet

affected with damp, the packing process is very necessary. The packing process is effectively handled

by our Semi-Auto Packing Machine.

Size range of making wood pellets:6mm, 8mm,9mm,10mm ,12mm
