Wood Pelletizing Machine

Wood Pelletizer Pachine For Sale

• Capacity :2.5-4.5T/h
• Ring mold size: 608mm/768mm
• Main motor :180kw /220kw
• Moisture : 12%-15%
• Application :Wood pelletizing machine is mainly used to convert sawdust, straw, husk and other raw materials into biomass pellets. The biomass pellet fuel produced by this equipment has the characteristics of high specific gravity, high calorific value, good combustion and low cost. It is widely used in domestic stoves, heating stoves, hot water boilers, drying furnaces, industrial boilers, for cooking and heating.

Wood pelletizing machine is a kind of equipment specially used to process biomass raw materials such as wood chips and sawdust into pellet fuel. Its working principle is to directly press the crushed wood chips into rod-shaped particles with a diameter of 4-12 mm through mechanical physical extrusion.

Wood pelletizing machine can efficiently convert raw materials such as wood chips into pellet fuel, improving production efficiency. The pellet fuel produced by pellet machine has the characteristics of low emission and low ash content, meets environmental protection requirements, and is increasingly popular in the market.

This equipment is not only suitable for wood chips, but also can process a variety of biomass raw materials such as straw and rice husks, with strong adaptability.

Wood chips and sawdust: This is the most common raw material, suitable for direct use in pellet processing, the moisture content is generally below 15%, and the pellet forming effect is good.

Crop straw: such as corn straw, rice straw, wheat straw, etc., can be used for pellet production after proper treatment.

Furniture production scraps: scraps generated during furniture processing must be crushed before they can be used in pellet machines.

Shavings: Shavings produced by furniture factories are divided into large shavings and small shavings. Small shavings can be used directly, while large shavings need to be crushed first.

Bark and branches: Usually need to be crushed and dried before they are suitable for pellet processing.

1.The horizontal ring die wood pelletizing machine is a special equipment for industrial biomass pellet production in large enterprises. It has high production capacity and the output of a single machine can reach 4.5 tons per hour. For large pellet plants, multiple horizontal ring die pellet making machines can be connected in parallel to achieve greater production capacity.

2.The machine uses special high-quality materials and advanced coupling transmission devices, and the key components are made of high-quality alloy steel and wear-resistant materials, which extend the service life by 5-7 times, ensuring the durability and reliability of the horizontal ring die pellet making machine.

3.The horizontal ring die wood pelletizing machine uses the principle of potential energy to increase the effective force arm and save more than 45% of energy, making the energy utilization rate higher and reducing energy waste in the production process.

4.The horizontal ring die wood pelletizing machine is equipped with ring dies with different apertures and compression ratios, and customers can choose according to specific requirements.

5.The ring die wood pelletizing machine uses German bearings and seals, and its stability is better than other products. In addition, during the pelletizing process, the moving distance of the rollers and ring dies on both sides is the same, and the wear is more uniform, which can save the cost of component replacement compared with small pellet mills.

1.Raw material preparation: First, wood chips, sawdust or other biomass raw materials are crushed to ensure that their particle size is suitable for entering the pellet machine.

2.Feeding system: The crushed raw materials enter the pelletizing chamber through a variable frequency speed feeder. The design of the feeding system can ensure that the raw materials enter the pellet machine evenly.

3.Heating and softening: During the pelletizing process, the raw materials are subjected to high temperature and high pressure under the high-speed rotation of the ring die and the pressure wheel, and the raw materials gradually soften.

4.Extrusion molding: The softened raw materials are extruded through the holes on the ring die to form continuous cylindrical pellets. The design of the ring die allows the diameter and length of the pellets to be adjusted according to demand.

5.Cutting: After the extruded pellets reach a certain length, they are cut by a cutter installed at the discharge port to form pellets of a specified length.

6.Cooling and packaging: Finally, the formed pellets need to be cooled to reduce the temperature and increase the hardness of the pellets, and then they can be packaged and stored.

A complete wood pellet production line includes crushing, drying, pelletizing, and packaging units. 

1. Crushing: Wood blocks, wood chips, or other wood materials are uniformly crushed. This can be done using a wood crusher or shredder to reduce the size of the wood into smaller pieces.
2. Drying: The crushed wood material is then fed into a drying machine drum through a conveyor belt. The drying process quickly reduces the moisture content of the material to around 12% to 15%. This is important for ensuring the quality of the final wood pellets.
3. Pelletizing: Once the wood material is dried, it is then fed into a pellet mill. The pellet mill compresses the material under high pressure and heat, forming it into small cylindrical pellets. The pellets are then extruded from the pellet mill.
4. Packaging: The pellets are discharged from the pellet mill and can be directly connected to a conveyor belt that leads to an automatic packaging machine. The packaging machine packages the pellets into bags
