EFB Pellet Machine: For Industrial Biomass Fuel Pellet Production
As the palm oil industry grows, more companies are focusing on recycling by-products like EFB. Palm empty fruit bunches are originally loose and take up a lot of space. After pelleting, they turn into biomass fuel pellets that are easy to store and transport, greatly increasing their value.
EFB pellet production demands high continuous operation and stability from the equipment. The RICHI EFB pellet mill has a minimum capacity of 300 kg/h. It features an industrial-grade design and can be flexibly configured based on project scale and capacity needs.
Since this equipment is for commercial production, it must meet long-term operation requirements. Its investment and supporting needs also differ from ordinary pellet machines. Therefore, this equipment is not designed for personal small-scale processing, home use, or occasional EFB handling. For clients with stable raw material sources and clear production plans—such as palm oil mills and biomass fuel companies—industrial-grade EFB pellet equipment offers more reliable production support.

What Raw Materials Can RICHI EFB Pellet Mill Process?
Different biomass raw materials vary in fiber content, moisture content, and storage condition, requiring different processing methods for pelleting. The RICHI EFB pellet machine applies to pre-treated palm empty fruit bunches (EFB) and various fiber-based biomass materials. It converts palm processing and agricultural waste into usable biomass pellets. The following lists the common applicable raw materials.
Palm Empty Fruit Bunch
A primary fibrous waste from palm fruit processing, rich in plant fiber. Due to its bulky texture and high moisture content, it usually requires pre-treatment like crushing and drying before pelleting. It can be processed into biomass fuel pellets.
Palm Kernel Shell (PKS)
Palm Leaf
Coconut Shell
Bagasse
Rice Husk
Peanut Shell
Corn Cob
Wheat Straw
Sawdust
Bamboo Dust
Cotton Stalk
Grass
After pelleting, these fiber-based biomass materials turn into denser, more uniform pellets.
Compared to their original loose state, the pellets are easier to store and transport. They are also more convenient to use in biomass fuel equipment, serving fuel applications such as industrial boilers.
Working Principle of the EFB Pellet Mill Machine
This equipment uses mechanical extrusion to process pre-treated palm empty fruit bunch (EFB) fiber into uniform pellets. The entire pelleting process requires adjusting processing conditions based on the fiber characteristics of EFB. This transforms the originally bulky and hard-to-transport palm waste into usable biomass fuel.
1.
Pre-processing EFB material enters the pellet machine
EFB fiber material, after crushing and drying, enters the pelleting chamber via a variable-frequency feeder. The uniform feeding method ensures the material continuously enters the working area between the ring die and the roller.
2.
The ring die and roller compress the material
Inside the pelleting chamber, the rotating ring die moves the material, and the roller continuously presses the material into the die holes. Under sustained pressure, the originally bulky EFB fiber is compressed. The fibers gradually bind together, forming a dense column of material.
3.
Compressed material is extruded from the die holes
When the pressure reaches a certain level, the compacted material is continuously extruded through the ring die holes. The hole size determines the pellet diameter.
For example, using a 6 mm die hole produces EFB pellets with a diameter of about 6 mm. Different ring dies can be replaced to meet various usage needs. The extruded material then forms continuous biomass strips.
4.
Cutter cuts the strips into pellets
The strips extruded from the ring die are cut by the cutter to form EFB biomass pellets of uniform length. The pellet diameter is determined by the ring die specifications, while the length is controlled by adjusting the cutter position.
For example, 6 mm diameter pellets can be adjusted to different lengths, such as 10 mm, 20 mm, or 30 mm, according to requirements.

EFB Pellet Production Questions Answered
Find professional answers to common questions, covering the key processes and important considerations in biomass pellet production.
1. What is the main use of the EFB pelletizer?
It is mainly used to process waste such as palm empty fruit bunches (EFB) generated during palm oil production. Through pelleting, loose and bulky EFB transforms into easy-to-store and transport biomass fuel pellets. These are used for industrial boilers, biomass energy projects, or fuel sales.
2. Can palm empty fruit bunches go directly into the pellet machine?
Usually, they cannot go directly.
Fresh EFB is typically fluffy, high in moisture, and has long fibers. These factors affect pellet forming. Therefore, before production, we need to determine if crushing, drying, or other treatments are needed based on the actual raw material.
EFB conditions vary across palm oil mills. The specific equipment configuration depends on your raw material situation.
3. What is the production process for EFB pellets?
EFB pellet production typically involves raw material handling, crushing, drying, pelleting, cooling, screening, and packaging.
The specific process is not fixed. It needs adjustment based on EFB moisture content, storage time, raw material supply, and target output. Some projects only need partial equipment additions, while large commercial projects usually require a complete EFB pellet production line.
4. What are the main advantages of EFB pellets?
After pelleting, EFB volume decreases significantly and density increases, making storage, transport, and subsequent use easier.
Compared to simply piling up EFB, pelleting makes palm waste easier to use as biomass fuel and reduces the disposal pressure caused by long-term waste accumulation.
5. Who is the EFB pellet machine suitable for?
The EFB pellet machine is mainly suitable for enterprises with a stable source of palm biomass and plans for long-term production.
For example, palm oil mills can use EFB by-products from production to reduce waste disposal pressure. Biomass fuel companies can process EFB into fuel pellets for sales or energy projects. Agricultural waste processing companies can also utilize abundant regional biomass resources for processing.
If you only process small amounts of EFB occasionally, or lack a stable raw material source, small-scale processing is generally not suitable for industrial-grade EFB pellet equipment.
6. What conditions are needed for EFB pellet production?
To build an EFB pellet production project, you first need a stable supply of EFB raw materials, as the equipment needs continuous operation to deliver value.
At the same time, raw material condition is crucial. EFB moisture content, fiber length, and storage time all affect the final production result.
Additionally, you need power conditions and production space suitable for industrial equipment operation, including space for raw material storage, equipment installation, and finished product storage.
7. How much does an EFB pellet production line cost?
There is no fixed price for an EFB pellet production line. The cost mainly depends on production scale, equipment configuration, and raw material processing needs.
If the EFB requires pre-treatment like crushing and drying, more equipment is needed, increasing the overall investment. Before finalizing the investment plan, we need to understand your raw material supply, target output, and production requirements.
8. Where can EFB pellets be used?
EFB pellets are mainly used as biomass fuel for industrial boilers, biomass energy projects, and the fuel supply market.
Compared to untreated EFB, pellet fuel is easier to transport and store, making it more suitable for commercial use.
9. Besides EFB, what other materials can the pellet machine process?
Besides palm empty fruit bunches (EFB), the biomass pellet machine can process various fiber-based materials, such as palm kernel shells, coconut shells, bagasse, rice husk, corn cob, straw, and sawdust.
Different materials have different properties. During actual production, we need to select the appropriate processing solution based on the material characteristics.
10. What is the difference between EFB pellets and ordinary wood pellets?
Both EFB pellets and wood pellets are biomass fuels, but their raw materials differ.
Sawdust usually has a stable source and a fiber structure that is relatively easy to process. EFB is a palm processing waste with variable moisture content and fiber condition. Therefore, producing EFB pellets requires more attention to raw material pre-treatment and equipment adaptation.
11. Why does EFB need crushing and drying before pelleting?
Because EFB raw material is usually loose, has long fibers, and high moisture when freshly produced. Crushing makes the material more uniform, and drying adjusts the moisture, bringing the EFB to a state more suitable for pelleting.
However, not all EFB projects require the exact same treatment. Whether crushing or drying is needed depends on your specific raw material situation.
