Biomass-pelletizing Technology market leader Efficient solutions for high capacity ring die Wood pelleting plants

Introduction for Wood pelleting plants

Ring die type Wood Pelleting plant tend to be regularly used for pellets making from medium to large-scale. The benefits of ring die system for eliminating roller skip are reduced power consumption, extended consumable parts life and improved pellet quality. The materials like sawdust,wood chips,wood logs, rice husk, sunflower seed shells, peanut shells, and other kinds of 

agricultural wastes go through crushing, drying, compression and finally formed solid biomass pellets. The final pellets can be 

used for industrial boilers and large power plants as well as home heating.

Features for Wood pelleting plants

1. This wood pelleting machine is usually equipped with 8mm and 10mm ring dies, because the 8mm and 10mm particle diameters are more favorable for combustion.Ring dies with other bore diameters can also be equipped according to different demands of users.

2.This wood pelleting machine adopts professional forced feeder, strengthened transmission parts, dedicated ring die, press roll and hoop.

3.The main driving adopts high-precision gear drive, so that the output is improved by about 20% when compared with 

that of belt drive.

4.Imported high-quality SKF bearing and oil seal are adopted to ensure efficient, stable and low-noise whole machine 

operation. The granulating room is equipped with air suction temperature-reducing system.

5.The feeder adopts variable-frequency and variable-speed motor to ensure the quality of discharged pellets.

6.Ring dies with multiple kinds of bore diameters are optional, and high-quality craft ring dies are adopted, so that the service

life is long, the discharged pellets are smooth and the quality is high.

7.International advanced compensation type snakelike spring coupling has the properties of novel and compact structure, 

high safety, low noise and low fault rate.

Biomass Pellets Benefits    

1.When burning, less ashes reminded, air pollutants emission reduced and carbon neutral without exacerbating the global warming. 

2.A wide range of raw materials adaptability includes wood materials, agricultural by products, even wood wastes from wood processing factory.

3.Regular and uniform shape, easy to ignite, high heat output, convenient to store and transport, especially suitable for automated heating system. 

4.Wood pellets can be used for home heating and industrial boilers and large power plants as well as animal bedding. 

5. It is applicable for stoves, furnaces,boilers and other heating systems.

Introduction for Complete pellet production lines

Our complete wood pellet production line 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 process.

Crushing process – Wood Hammer mill

• 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 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

• 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 

• 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 milldepend on your capacity requirement. Our  Ring die pellet mill is best choice for large scale production, while, our

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

• 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

• 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.
