How to produce wood pellets from different raw materials?
As for the wood pellet production line, everyone knows that it is used to process wood pellets. However, when faced with wood raw materials of different sizes, irregular shapes, and different moisture contents, everyone has questions about “how to process these raw materials into wood pellets”. Below, RICHI MACHINERY will list “how to process wood pellets” for these raw materials one by one. (The difference between these raw material granulation is mainly in the raw material handling stage, starting from granulation, the process flow can be the same.)
how to make wood pellets from wood log?
If your raw material is wood log, you need to go through slicing, crushing, granulation, cooling, screening, packaging and other processes to get the finished pellets. If the log diameter is not particularly thick, you can use a slicer directly.
Your logs may be coarse or fine, may have bark, or may have high moisture content. Your raw materials may be all logs, or may be part logs and part sawdust…
Using logs as raw materials, formed by solidifying and extruding into high-density pellet fuel through pretreatment and processing. It can save energy and reduce emissions, will make good economic and social benefits. It can be widely used in biomass power plants, biomass steam boilers, household fireplaces, drying stove and biomass gasifier, etc, is an efficient and clean renewable energy source.
how to make wood pellets from wood chips?
Wood chips refer to the wood left over from logging, lumbering, processing, etc. and directional cultivation. The leftovers are solid fuels. We can process wood chips into wood pellets through cleaning, crushing, granulation and other processes; we can also process different wood raw materials into wood chips for a variety of uses.
how to make wood pellets from sawdust?
No matter what your raw materials are, before the pelletizing process, all raw materials must be reduced to sawdust of about 3mm. If your raw materials are sawdust, then the equipment cost of your pellet production line will be very low, because you can save the investment cost of crushing equipment.
how to make wood pellets from shavings?
Wood shavings are larger than sawdust, produced by scrapers and / or other woodworking tools, usually come out in a spiral shape. Our equipment can process shavings for animal bedding, or directly use pellet equipment process shavings into wood pellets through processes such as crushing and granulation.
how to make wood pellets from Yard Waste?
Typical types of yard waste include grass clippings, leaves, branches, tree trunks, cut flowers, bushes and shrubs, festive plants, etc. The focus of the pellet production line design for this type of waste is on the raw material handling and pulverizing system because of the variety of materials. The process after crushing is the same.
how to make pellets from Furniture waste?
Reducing furniture waste is becoming a growing concern in the world. Among them, wooden waste furniture is a very good raw material for wood pellets. Due to the different shapes of the raw materials and the presence of impurities such as nails, it is necessary to add iron removers and cleaning equipment while crushing.
how to make wood pellets from tree stump?
Generally speaking, for raw materials such as tree stumps and roots, it is necessary to add shredders, wood hammer mills, drum screens and other equipment to the wood pellet production line to remove impurities while crushing and ensure pellet quality.
how to make wood pellets from Wooden Pallets?
Waste pallets are a special type of wood waste. In the design of this type of wood pellet production line, a correctly specified pallet shredder will enable the conversion of bulky pallet waste into biomass pellet fuel, that is uniform and easy to handle.
how to make wood pellets from wood board?
Panel board was the first main off-take for recycled wood fibre and remains a major customer for today’s wood recyclers. There are many ways to crush this type of raw material. We will configure suitable crushing equipment based on production scale.
how to make wood pellets from Demolition/construction wood?
However, 10-15% of all timber in new construction goes to the waste stream, with timber from demolition contributing to 10% of all landfill waste globally. The variety of these raw materials requires a customized raw material handling system.

how to manufacture wood pellets? standard wood pellet production process design
The standard process of wood pellet production line is: crushing – cleaning – drying – granulation – cooling – screening – packaging. In fact, the process design of wood pellet production line is customized according to customer needs, raw materials, plant structure, investment budget and other factors.
Some customers need a continuous fully automatic pellet production line; some customers’ raw materials are dry and do not need a drying system; some customers’ raw materials are 2-3mm in size and are clean and free of impurities, so there is no need for crushing and cleaning systems; some customers have a low investment budget and only need a separate pelletizing system; some customers need to use a ton bag scale to package pellet products, and some customers need silos to store finished products…
Although customers have different needs, in the past few decades, we have met the wood pellet processing needs of every customer and enabled their production lines to achieve efficient and high-profit operation.
1. Crushing system
Shredding, slicing, crushing, wood peeling, wood splitting, wood pallet crushing, etc. According to the different raw material sizes and impurities, we will combine these equipment into different crushing systems and process them into 3mm sawdust to meet the feed specifications of the wood pellet mill.
2. cleaning system
Most raw materials contain impurities, such as dirt, nails, etc. The cleaning section may be placed before or after crushing. This needs to be determined according to the actual situation of the raw materials. In a wood pellet production line using multiple raw materials, sometimes a multi-stage cleaning section is required.
3.Proportion & mixing
When customers use different types of raw materials, or use the same type but with different physical properties, in order to ensure the quality of the pellets, it is sometimes necessary to add this section. Of course, there are also very few customers who use adhesives. This requires a batching and mixing system to ensure the uniformity of the material.
4. Drying system
Before pelleting, the raw materials must be dry. Depending on the raw materials used, the moisture content should be between 13% and 15%. In order for the pelleting process to work properly, the raw materials should have the right amount of moisture. Drying the raw materials to the right amount of moisture is crucial for making high-quality pellets.
5. pelleting system
The diameter of the processed finished pellets is 2-12mm. RICHI’s MZLH series wood pellet press can process various wood pellets. The transmission part uses high-quality imported bearings and has a number of innovative designs on the ring die, which improves the hardness of the ring die, prevents cracking, and further enhances production capacity and life .
6.cooling system
Granulation, cooling, weighing and packaging. The temperature of the granules after cooling is generally not higher than 5°C from room temperature, and the moisture content of the granules after cooling is less than 10%, which is convenient for storage.
7. screening system
After pelletizing, in addition to qualified wood pellets, some unqualified particles and some dust will be produced. This requires the use of screening equipment to separate qualified and unqualified products. Qualified wood particles directly enter the packaging section, and unqualified particles need to be re-pelletized.
8. packaging system
RICHI can adjust the packaging equipment according to the customer’s requirements for finished product packaging. It can also be stored in bulk or in steel silos.
In addition to the above main pellet production line systems, according to process needs and customer needs, we can also configure Conveyor system (essential), raw material storage system (optional), semi-finished product storage system (optional), pellet storage system (optional), pellet bulk system (optional), dust removal system (necessary), etc. for customers.
In addition, we always prioritize plant safety and therefore offer various safety technologies, such as an active fire system with spark detection and extinguishing and put large effort in designing sophisticated dust aspiration systems.
raw materials Requirements of wood pelletizing technology
If you want to process wood pellets, if you want to complete an efficient and durable wood pellet production line, you need to determine several important factors when designing the production line: the type of raw materials, the size of the raw materials, and the moisture content. These factors will affect the design of the production line’s crushing system and drying system.
Raw material type
Your raw materials can be various wood raw materials, and you can use one, two or more raw materials of different sizes and moisture; your raw materials can be a combination of wood waste and agricultural waste, and you can also use raw materials of different sizes and moisture. The crushing system and drying system need to be determined according to the actual raw materials.
Raw material size
The raw material size here refers to the size of the raw material before entering the granulation section. Your raw material can be in various shapes, but before entering the granulator, you need to use a combination of crushing equipment to make your raw material size reach about 3mm.
What is the moisture of your main/primary raw materials?
If your raw material moisture =< 20%, then don’t need drying system in your design. If your raw material moisture > 20%, need drying system in your wood pellet production line design. If you want to save money, natural drying is also an economical option.

customer stories
You should be very interested in the projects we have done. Below, RICHI will introduce 6 projects in detail. I hope you will have a deeper understanding of the construction of wood pellet production lines.
10-12 t/h wood pellet production line in Brazil
The customer is an energy company from Brazil. In 2022, it plans to construct a 30,000-ton wood pellet plant in the municipality of Butiá, Brazil. Finally, the customer signed an agreement with RICHI Machinery in March 2023 to purchase a full set of wood pellet production line equipment.
The project uses the existing 1# plant, 2# production plant, comprehensive building and guardhouse, covering an area of 5795m2, relying on local power supply and water supply and drainage projects.
The customer plans to sell its pellets, made from eucalyptus, into the domestic and export markets. When operational, it’s expected the plant will employ 12 and create 60 indirect jobs. In June 2023, the company has secured an environmental license by the city.
wood pellet production line process design
- Chipping/crushing: Large raw materials such as waste wood are crushed into fine materials, and then transported to the hammer mill for crushing. Small raw materials such as bamboo sawdust, wood shavings, sawdust, etc. are directly fed into the hammer mill.
- Screening: The fine raw materials after crushing are transported to the screening machine for screening, and qualified crushed materials and metal debris such as iron nails and iron wire contained in the original raw materials are screened out.
- Drying: This process dries the material to a moisture content of 15%. The heating temperature of the project’s biomass thermal oil furnace is 110℃, and the ignition point of wood is 250~260℃.
- Granulation: The dried biomass powder is transported to the biomass pellet mill machine for pressing.
- Cooling: The pelletized biomass pellets are transported to the cooler for cooling to ensure that the biomass pellets remain dry and intact during the cooling process to achieve the molding effect. The cooled pellets enter the screening equipment to screen out unqualified pellets.
- Packaging: The qualified products are packaged by the packaging machine.
7-8 t/h wood pellet production line in south Korea
The client is a furniture company in South Korea. Due to development needs, it invested in this 8t/h biomass wood pellet production line in South Korea project.
In this project, RICHI Machinery provides a full set of equipment for a 20,000-ton wood pellet production line, with an investment of about US$450,000. The raw materials used in this project are all from the processing waste of its furniture factory, that is, wood scraps. When the scraps are insufficient, logs will be used directly. Therefore, according to customer needs, we also configure slicers for customers.
The labor quota of this project is 10 people; there is no production at night; the annual production days are 300 days. This project only has an employee canteen and no dormitory.
wood pellet production line process design
- Crushing: After the raw materials arrive at the site, some of them need to be crushed, and then loaded by a loader and lifted into the silo (the pelletizing extrusion compression equipment can reach about 100℃-120℃, and its own high temperature can be used to remove moisture);
- Storage: The silo is equipped with a level meter to control the loading of the elevator to prevent the elevator from stopping after the silo is full;
- Cleaning: A drum screen (with a magnet inside) is set at the bottom of the silo. Because some wood chip raw materials contain iron tools such as iron nails, iron impurities are removed to ensure product quality.
- Granulation: The cleaned raw materials enter the wood granulator for granulation.
- Cooling and screening: After being made into granules, they are lifted into the silo by a belt conveyor and cooled and screened by an air-cooled cooling unit. After screening, the particles that do not meet the specifications are recovered and returned to the silo.
- Packaging: Qualified pellets are loaded by bucket elevators to the silo to be packaged, packaged by computer quantitative packaging machines, and then stored and sold in warehouses.
4-5 t/h wood pellet production line in Pakistan

wood pellet production line process design
- Screening：Screen the raw materials (sawdust, straw) to remove the impurities (large particles of sand and gravel).
- Crushing and pulverizing： Purchase raw materials (the raw materials used in this project are dry raw materials, and the moisture content of raw materials is ≤10%), and manually put the raw materials into the crusher for crushing. The materials after preliminary crushing are then sent to the crusher for crushing through a bucket car. Some of the raw materials contain iron nails, which need to be removed. The project crusher and crusher are equipped with iron removal devices (magnets).
- Drying：The moisture content of the raw and auxiliary materials entering the site is about 40%. Drying can remove some moisture, but the process requires the moisture content to be below 20%, so the raw materials need to be dried. The dryer used in this project is an electric dryer, which can effectively reduce the moisture content of the raw and auxiliary materials to below 20%.
- Pelleting: This project conveys the crushed powder through a belt to the hot pressing biomass pellet machine, and presses it into granules under high pressure.
- Natural cooling: The molded product is transported to the stacking table by the elevator. After being lifted by the elevator, it is naturally cooled in the elevator funnel.
- Packaging: When the temperature drops to room temperature, the product is packaged and stored for sale.

How to build a complete wood pellet production line?
The specific steps and key elements of building a wood pellet production line are as follows:
- Raw material supply: First, a stable supply of raw materials needs to be ensured. The choice of raw materials should have market competitive advantages, such as wood waste, crop straw, etc., which are not only low-cost but also stable in supply.
- Equipment selection: Choose the right equipment according to the type of raw materials. For example, a ring die pelletizer is the best choice for wood pellet processing; raw materials with high moisture content need to be equipped with a dryer, while large-sized raw materials need to be equipped with equipment such as shredders and slicers. Choose equipment with good configuration and good after-sales service, and it is best to provide training.
- Site selection: It is very important to choose a suitable site, and it is necessary to ensure that electricity and water supply are convenient. Industrial parks can provide more convenience and compliance, while remote suburbs can save costs. Compliant locations should be selected for long-term development.
- Production line planning: The production line should be reasonably planned to ensure that it passes the safety and environmental assessment and achieves dust-free and safety. Automation and closed conveying systems can reduce labor costs and suppress dust.
- Environmental issues: Before building a pellet plant, environmental issues must be addressed, including equipment dust treatment, noise reduction, and safety assurance2.
- Plant requirements: The plant height should be no less than 7.5 meters, the ground should be hardened by 30 centimeters, and sufficient operating space and storage space should be left. The working environment should be appropriately advanced and automated, and dust removal equipment should be added.
- Production management: Standardized production management, reasonable arrangement of personnel positions and production processes, to ensure output and quality. Automated feeding systems and closed storage systems can reduce personnel costs and improve safety3.
- Sales channels: Reasonable use of sales channels, such as boiler usage information provided by environmental protection departments, and publicity through platforms such as Douyin.
- Fund utilization: Reasonable planning of production, allocation of supply and raw material storage, to ensure the effective use of funds.
Through the reasonable arrangement of the above steps and elements, the wood pellet plant can be effectively built and managed to ensure its long-term stable operation.
