RICHI MACHINERY
brief introduction for Wood pellet production line
The wood pellet production line is a specialized equipment designed to process wood waste such as sawdust, bark, and branches. This production line primarily uses physical compression to transform these materials into high-density, easily storable biomass fuel pellets. The final wood pellets have a high calorific value and burn without sulfur or phosphorus, which makes them an efficient and eco-friendly new fuel. These pellets can be used in industrial boilers, home heating, power generation, etc. With a wide range of applications, they can realize clean energy production and efficient resource recycling.
The RICHI wood pellet production line primarily manufactures wood pellets but can also process other biomass materials such as hay and organic fertilizers. When selecting a production line, we must consider the type of raw material, production capacity requirements, and local environmental policies to ensure efficient and compliant operations. With growing awareness of environmental protection, the market demand for wood pellet production will continue to expand.
wood pellet Production Line Working Video Introduction
The wood pellet production line is an integrated industrial system that transforms loose wood raw materials, such as wood chips, shavings, sawdust, and branches, into high-density and uniformly shaped cylindrical solid fuel pellets through a series of physical processing steps. The wood pellet production line is a modern and industrialized solution that transforms biomass waste into high-value clean energy.
Due to variations in production capacity, raw materials, and manufacturing specifications, the required production workflow will differ accordingly.
Wood Pellet Production Line Process
Here I will take raw material as logs as an example and introduce you the process of 2-2.5T/H complete wood pellet plant in detail.
1.Wood chipping
First of all, the logs enter the chipper through the conveying equipment, the chipper can cut the logs to 3-5mm thin wood chips, which is convenient for the subsequent crushing process, and also beneficial to the drying of raw materials.
2.Wood crushing
For different types of raw materials, the equipment is provided with different specialized crushing devices. Finally, all raw materials are transformed into powdered material with a particle size of 3-5mm, which is convenient for subsequent pelleting.
3.Wood Drying
This step directly determines the quality and storage life of the final pellets. The drying system of the wood pellet machine will rapidly reduce raw material moisture to approximately 15% through precise temperature control.
4.Pelleting
We offer machines with different pellet specifications according to various situations, usually ranging from 2 to 12 mm in size. In the pelleting section, the wood chips enter the wood pellet machine through the feeder and are converted into wood pellets under the extrusion of the pressure rollers and the ring die.
5.Pellets Cooling
The freshly produced pellets are at a high temperature and will first pass through a cooling device to reduce their temperature to room temperature. They are then processed through a shaking machine to remove a small amount of dust and crumbs, which can produce the final pellets.
6.Weighting and Packing
After cooling, we can weigh and pack the wood pellets. There are typically two packaging methods: wire sealing or plastic packaging. Plastic packaging keeps the product in a sealed state.This prevents the pellets from absorbing moisture for the better storage.

Advantages of Wood Pellet Production Line
The core advantage of investing in wood pellet lines lies in transforming low-value waste into high-value green energy through mature technology, with a perfect alignment of economic and environmental benefits.
Versatile Applications
Our equipment can be used in multiple industries including wood processing, renewable energy, industrial heating and agriculture. Whatever biomass material you process, we can offer the suitable solution.
Highly Automated
The wood pellet production line operates fully automatically from material feeding to packaging, which only requires 1-2 operators. This saves labor and improves production efficiency.
High Product Value
Processed wood pellets have a high calorific value, which is close to that of standard coal. Their market price is significantly higher than the value of waste wood, and the profit margin is substantial.
Convenient Storage
The produced pellets feature high density, compact size, and uniform shape, which is very convenient for storage and long distance transportation.
Low Material Costs
The primary raw materials for the wood pellet production line are the waste of forest and agriculture. These materials serve as production resources with enormous cost advantages, which might require payment for disposal.
Clean and Eco-Friendly
Compared to coal, wood pellets have low sulfur and minimal nitrogen oxide emissions, so there is no need to worry about failing environmental standards. They truly achieve clean combustion with no burden.
Recycling Generates Revenue
What is worthy of our attention is the insignificant ash left after burning, which is actually a high quality organic potassium fertilizer. For farmers, they can be directly spread over vegetable gardens and orchards for supplementing nutrients. For landscaping applications, spreading ash from burning materials not only helps control pests but also provides essential nutrients to promote tree growth.
Customized
RICHI offers multiple wood pellet production line design solutions. Customers may select from existing options or ask our industrial machinery designers to customize a solution to your specific requirements.

FAQ About Wood Pellet Production Line
1
What raw materials can be used?
The wood pellet production line has a wide range of raw material, including wood chips, sawdust, shavings, branches, and wood scraps. However, raw material requirements are stringent: materials must typically be in a powder form of 3-5mm in size, with moisture content strictly controlled between 13% and 18%. Excessive moisture prevents proper pellet formation, while insufficient moisture may cause carbonization of the raw material.
2
Why are the pellets loose and poorly formed after extrusion?
Possible causes include: First, the moisture content of raw materials may not be within the optimal range of 13%-18%. It is recommended to purchase a moisture meter for real-time monitoring. Second, the compression ratio required for producing softwood pellets differs from that for hardwood pellets, which requires timely adjustment of the ring die compression ratio. Additionally, a worn die or roll is a common cause of reduced output and discharge difficulties, which requires regular replacement.
3
Why is the output not reaching the equipment’s rated capacity?
There are some possible reasons:
1. Raw material issues: High proportion of hardwood, excessively long fibers, unstable moisture content.
2. Die issues: Incorrect compression ratio used or worn-out old dies.
3. Operational issues: Uneven feed rate, improper die-roll gap adjustment.
Our wood pellet production line’s rated capacity is measured under ideal conditions and with specific raw materials (e.g., pure pine sawdust). Actual output may fluctuate due to variations in raw material composition.
