EFB Pellet Machine
Don’t worry. RICHI’s EFB pellet machine can definitely help you. We have made targeted reinforcements to several key components such as the feed inlet, roller and ring die, making it more suitable for handling such difficult raw materials as EFB.
Product Introduction
What is EFB Pellet Machine
Capacity: 0.2-4 T/H
In a nutshell: It is a device that can process oil palm empty fruit bunches into pellets.
After palm oil is extracted, a large amount of wet and tough fibers remain as empty fruit bunches. These bunches may seem useless, but EFB pellet machine can compress these empty fruit bunches into high-density, stable-calorific-value pellets, which can be used as fuel for boilers or power plants.
RICHI’s EFB pellet machine is specially designed for the characteristics of oil palm empty fruit bunches, ensuring less clogging and fewer shutdowns during production, longer-lasting ring dies, and the production of uniform and solid pellets. This allows you to be more confident whether for external delivery or internal use.

Main Components of EFB Pellet Machine
The EFB pelletizer can be imagined as a human body system, where different parts perform their own functions and work together to create this machine capable of perfect pelletizing. The following are some of its main components.
Variable-Frequency Anti-Bridging Feeder
As the name suggests, this is the place where raw materials are fed in. The feeding speed comes with a variable‑frequency drive, so you can adjust it flexibly to match your main unit’s capacity and the moisture level of your materials. That way, you never get an uneven feed – too much one minute, too little the next.
We also designed this inlet with a double‑roller arch‑breaking structure and a large‑diameter feed opening, and the main goal is to keep the material flowing smoothly. The two rollers rotate in opposite directions, constantly stirring the EFB material to break it apart. At the same time, the wide opening reduces the chance of material sticking to the walls, which means less resistance going down.
Granulation Chamber
This is the core part of the entire EFB pellet machine, where the formation of pellets is completed. The three components in the granulation chamber – the press roller, the ring mold, and the cutting knife – work flexibly to produce perfect pellets. Any one of them is indispensable.
The press roller is a special press roller for biomass. Its surface has teeth, which can tightly “grab” EFB raw materials. Under the strong squeezing of the press roller, the EFB raw materials will be pressed into the ring mold. The ring mold has small holes of the same pellet size on its surface. After being squeezed, the materials will “pop out” from here. Subsequently, these elongated strips will be cut into the same length by the cutting knife, and the granulation process is thus completed.
High-Power Motor
Just as a person needs a strong body for intense exercise, an EFB pellet machine needs a reliable power source under heavy loads – and that’s the drive and transmission system.
We use Siemens motors ranging from 22kW to 250kW. They deliver plenty of power, so they handle the high resistance of EFB biomass materials with ease.
We also reinforced the whole transmission design to ensure smooth power delivery – no slippage, no energy loss. Even under continuous full-load operation, it won’t overheat or overload easily. That keeps your production steady and extends the life of your key components.

Customer Cases of EFB Pellet Machine
Here are several cases of EFB pellet machines from renowned enterprises being implemented overseas. Each customer faced their own challenges, and all of them were successfully resolved. Perhaps these cases can provide some references for you when choosing equipment.
Advantages of EFB Pellet Machine
To handle EFB, which is a difficult-to-process raw material, you really need some genuine skills. Our EFB pellet machine uses some key technical features to bring many advantages to the entire machine.
The overall frame of the EFB pellet machine has been thickened, making it extremely rigid. This ensures that the machine operates with minimal vibration, allowing the key granulation components such as the ring die and the roller to function stably and reliably. Even under high-load operation, the entire machine will not pose any safety issues.
Of course, everything requires precautions. What if there are abnormal situations such as blockage or overload? Don’t worry, we have equipped the equipment with an overload protection device. If any of these problems occur, the safety components will automatically break, and the limit switch will automatically stop the machine. This protects the core components such as the ring die, roller, and gearbox.
Safe Enough
The raw material fibers of EFB are relatively coarse. After a series of granulation processes, many components will be involved, and over time, the core granulation components will inevitably suffer wear. To minimize wear and extend the equipment’s service life, the ring die we use is forged from 42CrMo alloy steel and has undergone carburizing hardening treatment on the surface, with a hardness of HRC 58–62. Its wear resistance is much higher than that of ordinary stainless steel, perfectly matching the coarse fiber raw materials.
Durable and Wear-Resistant
If a single EFB pellet machine can only produce a fixed-sized pellet, it will result in unnecessary investment. You must be concerned about whether there is any method to freely adjust the compactness or diameter size of EFB pellets? Of course, there is!
Our equipment can adjust the compression ratio within the range of 1:10 to 1:18 according to your raw material conditions. By replacing molds with different hole diameters, you can obtain pellets of different thicknesses. It is extremely flexible. In addition, the inner wall of the ring die’s hole has undergone precise polishing, with a roughness control of Ra ≤ 0.8 microns. When the EFB raw materials pass through, it is particularly smooth and less prone to clogging.
Flexible to Use
Application of EFB Pellet Machine
EFB fibers are long and moist, and capacity needs vary widely across projects. Our EFB pellet machines cover 0.2 to 4 tons per hour, producing 4-12mm pellets steadily. Below we’ve outlined three typical scenarios by machine size.
Small-Scale for Personal Use
Suitable For：small palm plantations and small palm processing plants
Compatible Models: MZLH320, MZLH350
Capacity: 0.2 – 0.5 T/H
Suitable for ordinary small palm plantations and small palm pellet plant projects. Mainly for internal consumption in the factory, directly converting the accumulated unused EFB waste into pellets and using them as fuel for the factory boiler. There is no need to spend money on waste treatment, and it saves the cost of purchasing coal and fuel. The equipment is small, easy to install, simple to operate, and the daily maintenance is worry-free. It is particularly suitable for small-scale self-use.
Medium-Scale General Model
Suitable For：medium-sized palm factories and local biomass fuel merchants
Compatible Models: MZLH420, MZLH520
Capacity: 1.0 – 2.0 T/H
Both models have a relatively moderate footprint and investment cost, and their production capacity is reasonably designed. They produce high pellet forming rates and uniform quality, perfectly meeting the needs of medium-sized production plants. The EFB pellets produced meet the required calorific value and can be stably supplied to small and medium-sized thermal power plants and industrial boiler users. They can also be exported in bulk to meet the flexible needs of regional supply and foreign trade orders.
Large-Scale Production Model
Suitable For：large palm groups, EFB pellet export enterprises
Compatible Models: MZLH678, MZLH768
Capacity: 2.5 – 4.0 T/H
Targeted at large palm industrial parks, large-scale production enterprises, and merchants engaged in overseas exports. The equipment supports long-term uninterrupted continuous production, with sufficient capacity and uniform stable pellet quality. The produced EFB pellets have good appearance and calorific value that comply with international standards. They can provide stable supplies to large thermal power plants and also be exported in large quantities overseas, fully meeting the requirements of large-scale production and foreign trade orders.
EFB Pellet Manufacturing Process
Some customers think that making EFB into pellets can be achieved simply with one granulation machine. However, this is not the case. A stable and efficient EFB pellet production line is a complex system project that involves multiple interrelated processes. RICHI not only sells EFB granulation machines but can also provide you with a complete equipment solution covering the entire process from raw material entry to finished product packaging.

FAQ
Here are common questions from customers – maybe you’ve got the same ones. Feel free to ask more.
Why is the production capacity listed in the product parameters as a range instead of a fixed number?
→
Because the variety of EFB, moisture content, fineness of grinding, oil content, whether other raw materials are mixed, etc., all directly affect the molding speed and production capacity of the granulation process. For example, for the same MZLH420 model, when pressing pure EFB dry material (with a moisture content of 15% and a fineness through a 4mm sieve), the production capacity is approximately 1.0-1.2 tons per hour; but if 30% of wood chips are mixed in, the production capacity can increase to 1.5 tons per hour. If the raw material moisture content is too high (20%), the production capacity may drop to 0.8 tons per hour. Therefore, the range we provide is a typical working condition reference, and the actual data should be based on the results of on-site raw material trial operation.
If you want to know the production capacity corresponding to your raw materials, you can send a small sample bag over. We will conduct a real measurement at the factory.
Can the compression ratio of the ring die be adjusted? Under what circumstances is a high compression ratio needed?
→
It can be adjusted. The compression ratio of the ring die refers to the ratio of the effective length of the die hole to the diameter of the hole. When the moisture content of the raw materials is relatively low (12%-14%) and the fibers are fine and soft, the compression ratio can be reduced, which leads to higher production capacity and lower power consumption. If the moisture content in the raw materials is relatively high (16%-18%) and the fibers are relatively coarse and hard, a high compression ratio can be used. In this case, the pellets produced will be very compact and less likely to become loose.
Is the ash content of EFB fuel pellets high? Will it be difficult to sell?
→
If it is produced in compliance with regulations and under good pre-treatment conditions, the ash content of EFB fuel pellets will stabilize at around 4%-5%, which is a recognized high-quality fuel standard in the industry. You don’t need to worry about the sales issue. Compared to straw pellets, EFB pellets have lower ash content and higher calorific value. Many industrial boiler factories, biomass power plants, and heating enterprises will purchase them in large quantities on a long-term basis.
How much does an EFB granulation production line cost?
→
This depends on various factors, such as the capacity of the equipment. If you only purchase one MZLH320 EFB pellet machine (without peripheral equipment), the price is approximately several thousand US dollars. If you want to complete the entire production line equipment (grinding machine, dryer, cooler, screening machine, etc.) and calculate based on the scale, you need to do it according to the size. If you are interested, you can contact us and inform us of your target production capacity and raw material situation. We will provide you with a detailed configuration list and quotation.
How long is the warranty period? Who can repair the equipment if there is a problem?
→
If you purchase our EFB pellet machine, you can enjoy a whole machine warranty of 12 months. For minor small faults that are not caused by human factors, we can remotely guide you on how to troubleshoot and solve the problem. For more serious faults, we can contact us to arrange professional technicians to come and solve the problem.
It should be noted that the wear parts such as ring dies, rollers, and cutting knives are not within the warranty scope. If these components are damaged, you can also contact us for shipment, and we have sufficient original factory parts.
Are there second-hand EFB pellet machines for sale?
→
No. We only sell brand-new equipment because the performance, lifespan and after-sales service of new machines are more reliable. Although second-hand EFB pellet machines might be cheaper, they may have hidden wear and tear. If you buy them, they might break down frequently and the repair costs could add up to be more than buying a new one. Of course, if your budget is limited, you can simply tell us and our engineers will try their best to customize a most cost-effective solution within your affordability.
