application of wood pellet processing plant
If you are optimistic about the prospects of wood pellet processing, as long as you have sufficient wood raw materials and wood waste, no matter which industry you are in, you can choose to build a wood pellet plant. Depending on the production scale, process and equipment, the investment amount of a pellet plant is different. If the budget is not high, you can start with a small wood pellet line. If the budget is sufficient, you can build a wood pellet production line of more than 5t/h, which will be more profitable and have a shorter payback period.

Requirements for raw materials
In the actual wood pellet processing process, there are requirements for the raw materials. Before entering the pelletizing process, they need to meet the three requirements of moisture, size and purity at the same time.
What is your Main/primary raw materials? (Aim to design crushing system)
You can choose one raw material or different raw materials. The crushing process and crushing equipment for different raw materials may be different.
Most are wood log? most are wood chips? most are wood sawdust? most are irregular shape’s waste of wood ? or others , such as EFB ? or crop such as straw, husk, shell, leaves, grass …. ?
What is the moisture of your Main/primary raw materials?
- Dry type moisture =< 20% ? if yes , dont need drying system in your wood pellet processing plant.
- Wet type moisture > 20%, if yes , need drying system in your wood pellet processing plant.
Are your raw materials clean? Do they contain impurities?
Some customers’ raw materials are pure sawdust, but most customers’ raw materials contain various impurities such as nails and cigarette butts, and they need to be equipped with screening and cleaning equipment, iron removers, permanent magnet cylinders and other equipment to remove impurities from the raw materials.

composition of wood pellet processing plant
A wood pellet processing plant is mainly composed of a cleaning system, a crushing system, a drying system, a pelletizing system, a cooling system, a screening system, and a packaging system. It also includes a dust removal system, a boiler steam system, an electronic control system, etc. Depending on the customer’s raw material and process requirements, a mixing system, a silo system, etc. are sometimes configured.
Richi Machinery can provide customers with complete tailor-made production solutions. By pursuing perfect quality control and after-sales service, we can precisely customize solutions to meet customers’ needs and have earned a reputation worldwide. We are always ready to serve you!
Cleaning section
This is the first process of the production plant and is crucial. The raw materials may contain impurities such as stones, metals, and plastics. If they are not cleaned up, they will damage subsequent equipment and affect the quality of the pellets. The cleaning section usually uses magnetic separation, screening and other methods to remove impurities.
Crushing section
The cleaned raw materials need to be crushed to a particle size of 3-5mm to meet the pelletizing requirements. The crushing section usually uses a hammer mill or chipper to crush the raw materials into fine particles, increase the specific surface area of the raw materials, and improve the pelletizing efficiency.
Drying section
Too high moisture content in the raw materials will affect the pelletizing effect, resulting in loose and brittle pellets. The drying section uses hot air drying to reduce the moisture content of the raw materials to less than 20%, thereby increasing the particle density and combustion efficiency. Commonly used drying equipment includes drum dryers, belt dryers, etc.
Granulation section
This is the core process of the wood pellet processing plant, which presses the crushed and dried raw materials into high-density pellet fuel. The wood granulator machine uses the strong pressure between the roller and the die to extrude the raw materials into cylindrical granules with a diameter of 2-14mm and a length of 10-30mm.
Cooling section
The wood pellets just out of the wood pellet mill are at a high temperature and need to be cooled before packaging. The cooling section usually uses a countercurrent cooler to use cold air to reduce the temperature of the pellets to near room temperature to prevent the granules from agglomerating and mildewing.
Screening section
The cooled wood pellets need to be screened to remove unqualified granules and powder. The screening section usually uses a vibrating screen to grade the granules by size to ensure uniform granule size and improve product quality.
Packaging section
Qualified wood pellets after screening need to be packaged for easy storage, transportation and sales. The packaging section usually uses an automatic packaging machine to pack the granules into bags according to a certain weight. Common packaging specifications are 15kg, 20kg, 25kg, etc.
Auxiliary system
Auxiliary system is an important guarantee for the normal operation of the production line, including dust removal system, electrical control system, steam system, silo system, etc. Some are required and some are optional. According to customer needs, we will configure suitable equipment for customers.

This is the promise from RICHI MACHIENRY.
01
4-5T/H wood pellet processing plant design
This is a process flow chart from one of our US projects. As can be seen from the figure, the customer uses two kinds of raw materials, one is sawdust, which needs to be cleaned by a drum screen. The other is logs, which are crushed twice by a slicer and a hammer mill, and then enter the drying drum together with the cleaned sawdust for drying.
The dried materials will be sent to the wood pellet machine through a bucket elevator for pelletizing, and then enter the cooling and screening section one after another. This project does not have a packaging section, because the processed wood pellets will enter the finished product buffer bin, and then enter the truck and leave the factory in bulk.
02
4-5T/H wood pellet processing plant design
This is a process flow chart from one of our New Zealand projects. This project only uses logs as raw materials, and the moisture content is not high. The process flow of this project is: the raw materials are sliced by a slicer, and then enter the wood hammer mill through a bucket elevator for fine crushing. The crushed materials are sent to the storage bin for temporary storage. The storage process will also help reduce the moisture content of the materials. Subsequently, the materials enter the pelletizing section for pelletizing.
After pelletizing, they enter the cooling, screening and packaging sections one after another. The packaged pellets are stored in the finished product warehouse. This project has a distinct feature from the previous American project: the plant height is relatively high. Therefore, the main conveying method is bucket elevator.
03
4-5T/H wood pellet processing plant design
This is a process flow chart from one of our Argentina projects. This project also uses two kinds of raw materials, one is sawdust, which needs to be cleaned by a drum screen. The other is logs, which are crushed twice by a slicer and a hammer mill, and then enter the drying drum together with the cleaned sawdust for drying.
The dried materials are piled in place, and the dried materials are sent to the pelletizer by a forklift. Then they enter the cooling and screening section one after another. This project has two packaging equipment, one is a conventional fully automatic packaging scale, and the other is a ton bag scale. They are used to package products of different specifications. The height of the customer’s factory is limited, so the curling conveyor is used.

5 t/h wood pellet processing plant design
- Crushing: The new design wood pellet processing plant project will manually sieve the purchased waste wood, waste wooden furniture and other materials that do not contain toxic and harmful substances such as paint and glue, and place large pieces (pieces) of raw materials through forklifts or forklifts. Crushing is carried out on the machine.
- Grinding: small pieces (pieces) of raw materials are crushed together with the crushed materials through a grinder (the particle size after crushing is less than 5mm), and the crushed wood powder is transported to the wood pellet machine.
- Granulation: Through the high-speed rotation of the ring die, the sawdust raw material begins to heat up and become soft (the pressure of the high-speed rotating roller can reach 300T, and the temperature of the sawdust can reach 100℃ to 130℃).
The softened and heated sawdust raw material is extruded through the holes of the ring die under strong pressure. During this process, the wood chip has increased compactness, reduced moisture content, and a compression ratio of 5.5:1. - Cooling & Sieving & Packaging: Then cool and dry naturally, and then sieve through the drum sieve in the conveyor belt. After the biomass particles are screened, they are transported to the finished product warehouse, where they can be packaged and shipped.
Note:
- The moisture content of the raw materials of the 5t/h wood pellet processing plant project is 8%-15%, which meets the requirements of granulation and molding, so there is no need to dry or add water during the production process;
- All wood raw materials are pure wood materials. It is strictly forbidden to recycle waste furniture with paint, glue, etc. On the one hand, it can improve product quality, and on the other hand, it can avoid the impact of introducing organic waste gas pollutants.
- The crushing, pulverizing and granulating process of the raw materials of the project are respectively carried out in the closed cavity of the crusher, pulverizer and granulator, and the pulverizer and the granulator are connected and transported through the closed pipeline.
General layout
The 5t/h wood pellet processing plant project building includes 2 workshops:
- Plant 1: The northwest is the crushing area, the northeast area is the crushing area and reserved workshop, and the south is the raw material area;
- Plant 2: The western area is the granulation area, and the eastern area is the warehouse.

Frequently Ask Question
Frequently Ask Question
How to invest in the construction of awood pellet processing plant?
Developing a wood pellet processing plant requires comprehensive consideration of multiple aspects such as raw material supply, equipment selection, production process, market positioning, policies and regulations, etc.
- Regarding investing in building a factory, first you need to purchase the entire production line. The equipment required depends on your feedstock, the smaller the physical size of the feedstock, the less equipment is required.
For example, if you use fresh logs, you need not only coarse crushing and fine crushing equipment, but also a dryer to process the raw materials. In this case, the investment will obviously be relatively high;
If you use dry wood chips, shavings (generally easy to obtain from sawdust mills, furniture factories, board factories), all you need are screening machines, pellet machines, cooling machines, and packaging machines.
Therefore, you need to fully consider the factors of raw materials to choose a wood pellet processing plant construction plan, or you can also consult us, and RICHI engineers will tailor a solution for you to help you succeed!
- In addition, the quality of the equipment cannot be ignored. Excellent and precise workmanship, high standard quality control means low machine failure rate and high pellet yield rate.
Selecting equipment for a wood pellet production line requires comprehensive consideration of factors such as raw material characteristics, production capacity requirements, process requirements, budget, and post-maintenance. The following are key steps and precautions:
- Clarify production requirements
- Raw material types: wood chips, sawdust, shavings, branches, etc. (the particle size, moisture, and hardness of the raw materials affect the equipment selection).
- Production capacity requirements: hourly output (such as 0.5 tons, 1 ton, 5 tons, etc.) determines the scale of the equipment.
- Particle specifications: diameter (6-10mm is common), length, density (usually ≥1.0g/cm³).
- Finished product use: home heating, industrial fuel, animal bedding, etc. (different uses have different requirements for particle quality).
- Core equipment selection
(1) Crushing equipment (raw material pretreatment)
- Coarse crushing: branches and wood blocks must first be processed with a chipper (such as a drum chipper) or a wood crusher.
- Fine crushing: hammer mill (suitable for raw materials with moisture <15%) or blade mill (more efficient for fiber raw materials).
- Key parameters: discharge particle size (generally ≤3mm), power matching capacity.
(2) Drying equipment
- Rotary dryer: suitable for large-scale production, heat source can be natural gas, biomass or steam.
- Airflow dryer: suitable for small-scale or low-humidity raw materials.
- Key parameters: reduce the humidity of raw materials to 10-15% (too high affects molding, too low increases energy consumption).
(3) Pellet mill (core equipment)
- Flat die wood pellet mill: Suitable for small-scale (<0.5 ton/hour) or fiber raw materials. Simple structure, easy maintenance, but low output.
- Ring die wood pellet mill: Suitable for large-scale production (0.2-10 tons/hour), high particle density. The ring die aperture and compression ratio need to be selected according to the raw material (4:1-6:1 is commonly used for wood chips).
- Key parameters: motor power (such as a capacity of 1 ton/hour requires about 90kW), ring die material (alloy steel has high durability).
(4) Cooling and screening
- Counterflow cooler: reduce pellet temperature (< ambient temperature + 5°C) and humidity.
- Vibrating screen: remove debris and ensure uniformity of finished pellets.
(5) Packaging equipment
Semi-automatic packaging machines are optional for small lines, and fully automatic weighing and packaging lines are used for large lines.
- Auxiliary equipment and systems
- Dust removal system: cyclone separator + pulse dust collector (in line with environmental protection requirements).
- Conveying equipment: belt conveyor (dry raw materials), screw conveyor (wet materials).
- Automation control: PLC system can optimize energy consumption and stability (optional).

What are the raw materials that can be used in wood pellet processing plant?
The wood pellet processing plant is suitable for a wide range of raw materials, mainly including forestry residues, agricultural waste, energy crops and other biomass materials.
- Forestry Residues
- Wood processing waste: sawdust, wood chips, shavings, off-cuts
- Forest harvesting residues: branches, tops, bark, small-diameter logs
- Secondary forest/economic forest: fast-growing tree species such as eucalyptus, pine, fir, and poplar
- Agricultural Residues
- Straw: corn straw, wheat straw, rice straw, cotton stalk, etc.
- Fruit shells/kernels: coconut shells, palm kernel shells, olive pits, apricot shells, etc.
- Other agricultural waste: Bagasse, Peanut Shell, Sunflower Husk, etc.
- Energy Crops
- Herbaceous Energy Crops: Switchgrass, Miscanthus, Reed Canary Grass, etc.
- Wooden Energy Crops: Short Rotation Trees (such as Willow, Poplar), etc.
- Other Biomass Materials
- Waste Wood: Building Formwork, Waste Furniture, Pallets, etc.
- Industrial By-products: Paper Mill Black Liquor (Special Treatment Required), Distillers Grains, etc.
- Bamboo, etc.
How to choose the raw materials for the wood pellet processing plant?
When choosing the raw materials for the wood pellet processing plant, the following key factors need to be considered:
Moisture content: The ideal range is 10%~20%, and if it is too high, it needs to be dried.
Ash content: Agricultural waste (such as straw) has a high ash content, which may affect combustion efficiency.
Binder requirements: Some raw materials (such as fruit shells) may need to be added with natural binders (such as lignin).
Economical: Obtaining raw materials nearby can reduce transportation costs (such as forestry waste in Northern Europe and palm waste in Southeast Asia). If you have a timber mill, furniture factory, sawdust mill, or palm oil mill, it also means you have ready-made raw materials to use.
