Complete wood pellet production line

wood pellets make green life

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.

Features

1. Reasonable technology, high capacity and low energy consumption.

2. Modular Structure: The plant is compact, occupies less floor space and has low requirement on the mill tower, and needs low investment in civil works.

3. The containerized modular structure is convenient for assembly and disassembly, facilitates the shipment and installation.

4. Centralized control: the analogue panel is adopted. All machines can be interlocked and safety, alarm device is available. The operation is simple and convenient.

Wood Pellets Processing Technics
A complete wood pellet production line for making wood pellets including:
Raw materials preparation, wood crushing (For logs and other biomass materials more than 5mm in dia.), sawdust drying (if the raw material contains moisture of more than 18%), wood pellets pelletizing, wood pellet cooling, biomass pellets packing.

Process of Complete Wood Pellet Production Line

1.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.

2.Raw MaterialCrushing Process
Crushing machine is used for crushing the larger materials into smaller powder for supporting produce wood pellets. Here we introduce two major machines for you: wood crusher and wood hammer mill. 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.

3.Biomass MaterialDrying Process
The best moisture content to pelletizing is about 10-20%. So before pelletizing, a drying machine is needed to make the moisture content reaches the required standards. You should choose the most suitable drying machine from rotary dryer and pipe dryer according to the wood powder moisture and handling capacity.

4.Wood Pelletizing Process
Pellet mill is the significant part of the wood pellet production line, and has reliable and stable performance. It is specially 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 requirements. Our XGJ series Ring die pellet mill is best choice for large scale production, while SKJ series flat die pellet mill is suitable for small pellet production line. The final wood pellets will have high density and high heating value. Any doubt please feel free to contact with us for detailed information.

5.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.

6.Wood Pellet Packing Process
After the cooling process, packing process is necessary to protect the wood pellets from the damp. Xiucheng automatic wood pellet weighing & packing system adopts PLC control with high weighing accuracy and easy operation is your best choice.
