Wood Chip Pellet Mill
Wood chip pellet mill is a typical biomass energy equipment. It can pelletize various waste wood materials, transforming them into high-quality clean fuel. We offer multiple models of wood pelletizers for your selection. For your production needs, we also provide customized pellet mill and production line solutions.
Working Principle
This wood pellet machine maker features an innovative structural design, delivering highly efficient and energy-saving production results. Whether processing wood chips, sawdust or complex mixed materials, it efficiently produces pellets that meet high-standard biomass fuel needs. Let’s get to know the main working principle of this device by watching the following video.
During this process, the wood chip pellet mill employs physical compression molding technology to complete the conversion through four key steps:
- Raw Material Crushing : Crushing raw materials into particles measuring 3-5 mm in size
- Moisture Adjustment : Controlling raw material moisture content within the optimal range of 13-18%
- High Temperature Compression : Forcing wood fibers to naturally bond through high-temperature, high-pressure extrusion through molds
- Molding and Cooling : Cutting into shape followed by cooling to improve pellet durability

Core Components Display
In addition to its overall structural advantages, the components of this wood pellet press machine also feature innovative designs. We design each unit with high quality materials, such as stainless steel construction, Siemens motors, and SKF bearings, which ensures the wood pelletizer’s high efficiency, stability, and excellent results.
Ring Die
The ring die is made from high-quality alloy steel through precision machining. Their aperture ratio is scientifically calculated to maximize output per unit. The surface undergoes carburizing heat treatment, delivering exceptional wear resistance. We can provide ring dies with various aperture sizes to achieve multiple pellet diameters.
Cutting Device
This wood chip pellet mill features a single cutting device that can produce longer, more durable fuel pellets. Located inside the discharge chute, the cutting device cuts the pellets as they are extruded through the die holes. Operators can adjust the distance between the cutter and the ring die to control pellet length.
Arch-Breaking Feeder
To accommodate the lightweight nature of wood chip material, we have specifically designed an arch-breaking feeding device. Its interior features two sets of spiral feed blades, paired with a dedicated motor. This device prevents lightweight materials from accumulating at the feed inlet, ensuring smooth feeding.
Control System
The electronic control system monitors and adjusts equipment operating parameters, including feed rate, pelleting chamber temperature and pelleting device operation. Operators can utilize the automated control system to make adjustments in time, in order to adapt to different raw materials and production requirements.
Full-Process Wood Pellet Production Line
We also provide complete wood pellet production line equipment. With scientifically divided production stages, it enables highly efficient wood pellet manufacturing. There is no fixed standard for the production process flow. The production techniques, equipment configuration and manufacturing technology can all be customized to meet your specific needs. We can also offer turnkey solutions for wood pellet plant, helping you to start production quickly and easily.
wood chipping
First of all, the logs enter the chipper through the conveying equipment, the chipper can cut the logs to 20-40 mm thin wood chips, which is convenient for the subsequent crushing process, and also beneficial to the drying of raw materials.
wood crushing
This step is fundamental to ensuring effective pellet formation. For different types of raw materials, the equipment is provided with different specialized crushing devices. Finally, all raw materials are transformed into powdered material with a particle size of 3-5 mm.
wood drying
Wood waste often contains high moisture levels. Excessive moisture not only hinders the formation of wood pellets during production, but also causes the final product to mold and deteriorate during storage. The drying system of the machine will rapidly reduce raw material moisture to approximately 15% through precise temperature control.
wood pelletizing
We offer wood chip pellet mill for sale with different pellet specifications according to various situations, usually ranging from 2 to 12 mm in size. In the pelletizing section, the wood chips enter the wood pellet press through the feeder and are converted into wood pellets under the extrusion of the pressure rollers and the ring die.
pellet cooling and screening
The freshly produced pellets are at a high temperature and will first pass through a cooling device to reduce their temperature to room temperature. They are then processed through a shaking machine to remove a small amount of dust and crumbs, which can produce the final pellets.
pellet packing
After cooling and screening, the wood pellets exhibit uniform specifications and dimensions. We have designed an automated pellet packaging scale for this stage, which enables standardized weighing and rapid packaging. This significantly reduces labor costs and pellet wastage.

Frequently Asked Questions
Before investing in machinery, you may have concerns regarding specific models, production capacities, raw material processing, detailed quotations, and more. Below, we will address these questions in detail. For an accurate equipment quote, please provide your production requirements to receive the most precise response.
What types of biomass materials can the wood chip pellet mill pelletize?
+
Our pelletizer is an industrial-grade machine with high utilization rates. It can pelletize not only shredded wood materials like wood chips, sawdust, and shavings, but also process various high-fiber materials such as straw, grass, and other agricultural and forestry waste. Provided the raw materials are properly shredded and processed, this machine consistently delivers efficient and stable output.
Why choose a ring die wood pellet machine?
+
For large-scale wood pellet plants and biomass pellet manufacturers, selecting a ring die pelletizer significantly enhances return on investment. This is because ring die pelletizers deliver superior compression performance and greater pelletizing capacity. Additionally, their robust construction ensures reliable operation for sustained production.
What equipment is required for wood pellet production?
+
A complete wood pellet production line requires a raw material processing system, pelletizing, cooling, screening, and packaging stages. Among these, the raw material processing and pelletizing stages directly determine the material’s forming rate and the quality of the pellet fuel.
Our wood pellet press is an industrial-grade advanced machine with excellent pelletizing capability. Common wood processing systems include three components: chippers, shredders, and dryers. These ensure appropriate raw material size and moisture content, facilitating efficient pellet production.
Does this industrial wood pellet press machine have specific requirements for raw material moisture content?
+
This requirement is a fundamental condition for wood pellet production, encompassing appropriate moisture levels and particle size. Standard raw material should consist of sawdust-like particles within 3-5 mm. This size facilitates optimal compaction.
The ideal moisture content ranges from 15% to 18%. Wood materials exceeding this range exhibit reduced formation rates and compromise pellet quality. Therefore, proper raw material preparation is crucial.
How to choose the right wood chip pellet mill?
+
When selecting equipment, you need to consider factors such as raw material conditions, target production capacity, and pellet size. These should be evaluated in conjunction with your investment budget. For large-scale wood pellet plants, a complete production line setup is required. Therefore, automation levels and equipment configurations also need to be taken into account. If you require a tailored solution recommendation, please feel free to contact us.
