2.5-3 T/H Sawdust Pelletizer Machine in Malaysia
The client operates a plant that produces carbonized pellets, utilizing wood scraps recovered from timber processing facilities as well as some palm waste. We designed a process flow for the client that involves pelletizing the material first, followed by carbonization.
The core pelletizing equipment is a ring-die wood pellet mill. Given that the client’s raw materials vary in form and have a high moisture content (30%–40%), we also incorporated a wood crusher and a dryer into the system.
20 t/h sawdust pellet making Machine in Bangladesh
The client has access to an abundant supply of wood waste (sawdust/wood chips) and intends to process it into pellet fuel for export to Japan and South Korea.
While the target production capacity is 20 tons per hour, the client also requires the flexibility to reduce output when necessary. To address this, we implemented a dual-line parallel design. Each production line features three wood pellet mills operating in parallel, with each mill capable of producing 3–4 tons per hour.
This configuration ensures high output while allowing for flexible switching during equipment maintenance, ensuring continuous operation. If a reduction in production is required, one of the two lines can simply be shut down.

0.2-0.3 T/H Sawdust Pellet Machine in Austria
The client’s raw materials consist of hardwood and softwood, with dimensions of approximately 35 mm. The proposed solution includes a wood crusher, a pellet mill, a bagging scale (15 kg/bag), and a cyclone separator.
0.3-0.5 T/H Sawdust Pelletizer in Côte d’Ivoire
The client wanted to process wood shavings into pellets but required a relatively low production capacity. To meet this need, we recommended the MZLH350 wood pellet mill, complemented by a hammer mill, cooler, vibrating screen, and bagging scale.
1.5-2 T/H Sawdust Pellet Mill in Poland
The client purchased an MZLH520 pellet mill. This model utilizes a ring-die pelletizing system, which ensures a high pellet formation rate and a low failure rate. In addition, the client also procured a supply of wear parts sufficient for 3–5 years of use.
2-2.5 T/H Sawdust Pellet Press in Romania
The client’s raw materials consist of beech wood chips and sawdust with a moisture content of approximately 40%; these must be uniformly pulverized and dried before being processed into pellets.
3-4 T/H Sawdust Pellet Maker in Canada
The client’s target production capacity is 4 tons per hour. While near-full capacity is required during the winter, production may need to be scaled back in the summer. To meet these requirements, we have configured the system with two MZLH520 pellet makers, each with a capacity of 1.5–2 tons per hour.
Customized Sawdust Pelletizing Solutions
Depending on the specific needs of each client, we offer customized solutions for pelletizing waste paper, providing end-to-end service that encompasses raw material analysis, process design, equipment selection, installation and commissioning, as well as after-sales support.
0.2-0.3 T/H Simple Sawdust Pellet Production Line
This Production line only has essential machinery—a crusher, pellet machine, storage silo, cyclone separator, and conveyor. It features a compact footprint and requires minimal investment, making it an ideal choice for micro-enterprises.
1.5-2 T/H Sawdust Pellet Production Line
The raw material for this client is wet sawdust with a moisture content of 55%, which must be dried before being pressed into pellet fuel. Therefore, in the production line design, we have included a sawdust drying machine to reduce the moisture content of the sawdust to 15% prior to the pelletizing process. Furthermore, drying the sawdust also facilitates its storage.
3-4 T/H Wood Pellet Production line ( two pelletizers)
This production line processes wood chips by grinding them into sawdust, drying the material, and then converting it into pellets. The client has opted for a configuration that includes two sawdust pellet mills; this ensures that if one mill is taken offline for maintenance, the other can continue to operate, preventing a complete shutdown of the entire production line.

Equipment Applications
Production processes vary depending on the intended use of the final product. For instance, when producing pellet fuel, the ring die compression ratio is typically between 1:5.5 and 1:7—or even higher—and the moisture content of the pellets must be strictly controlled. For the production of wood-based cat litter, the ring die compression ratio is generally between 1:3 and 1:4. Please let us know the intended use of your final product, and we will develop a customized solution for you.

Key Components
Ring Die
Made of high-strength alloy steel and subjected to carburizing and quenching heat treatment. The die holes feature a high-quality, smooth finish and excellent wear resistance.
Press Roller
The gap between the ring die and the pressure rollers is adjustable, helping to prevent equipment damage or clogging.
Siemens Motor
Siemens motors offer high energy efficiency and low energy consumption; they feature strong overload capacity, a low failure rate, and an exceptionally long service life.
safety pin
When the pellet mill becomes clogged or overloaded, the shear pin will automatically break, protecting critical components from damage.
Cutter Assembly
Features an externally positioned adjustment handle, allowing for flexible control over pellet length.

Frequently Asked Questions
In addition to sawdust, my raw materials include wood shavings, wood chips, and various other forms of wood waste—can all of these be processed into pellets?
Certainly. Before pelletizing, you simply need to grind these various types of wood waste into a uniform particle size (3–5 mm) and ensure the moisture content does not exceed 15%. Once these conditions are met, they can be processed into pellets. We offer a range of size-reduction equipment tailored to different types of wood waste, including wood pallet chipper, wood shredders, and wood chip hammer mills.
What size pellets can your sawdust pellet machine produce?
The pellet size is determined by the diameter of the holes in the die. Generally, we offer dies with hole sizes ranging from 4 mm to 12 mm. If you require a different size, we can also provide custom-made dies for you. The length of the pellets can be adjusted as you wish.
Can your pellet machines only process wood chips? I would like to produce pellet fertilizer using a mixture of sawdust and raw manure—is your equipment capable of handling this?
Certainly. We can design a suitable production process tailored to your specific raw materials and the requirements for your finished product.
Do you supply wear parts such as ring dies and rollers?
We provide a consistent supply of various wear parts; when purchasing a pellet mill, you may also choose to buy enough spare parts to last for 3–5 years of operation.
I want to set up a wood pellet plant; what equipment do I need?
A standard wood pellet production line typically includes a hammer mill, a pellet mill, a pellet cooler, a screening machine, a packaging machine, conveying equipment, and a dust collection system. However, depending on the size and moisture content of the raw materials, additional equipment—such as a wood chipper or a wood dryer—may also be required.
How long is the equipment warranty period?
The entire unit comes with a one-year warranty; any non-human-caused malfunctions occurring within this period will be repaired free of charge. （view our YouTube）
