Equipment Structure
Many first-time buyers aren’t sure how to choose the right equipment. Let’s start with the internal structure of the RICHI Sawdust Pellet Mill to help you quickly understand this machine.
Equipment Structure
The main components of the sawdust pellet mill are feeder, pelletizer, motor, transmission device and overload protection device. We have precision engineered every component and used the best materials to ensure this machine is easy to use and durable.
Feeding System
The feeding port is at the top of the machine. We designed an anti-arching hopper, mainly to break up the wood chips and prevent them from clumping. In addition, the feeding system is equipped with a variable frequency speed control motor and a propeller blade design, which can force the “difficult-to-feed” wood chip raw materials into the pelletizing chamber.
Pelletizing System
The ring die and roller are the core components of pelletizing. Usually, the forming diameter on the ring die is the diameter of the finished pellets. Because they are in direct contact with the raw materials, our machine uses more wear-resistant stainless steel material.
The ring die and roller perform strong extrusion, and the cylindrical pellets are evenly discharged. At this time, the knives on both sides of the ring die cut them into the appropriate length. The wood chip pellets are made.
Power System
From forced feeding to compression pelletizing, these links have very high requirements for electric drive. We are equipped with Siemens generators, with power coverage of 22-315KW. Even if you use the machine for 24 hours of continuous processing, you don’t have to worry about production fluctuations caused by motor fatigue.
Transmission System
The main transmission of the Sawdust Pellet Mill uses gear transmission, which runs smoothly and is not easy to slip. At the same time, it introduces international advanced compensating type serpentine spring couplings, as well as SKF bearings and imported oil seals, offering outstanding vibration damping and power transmission.
Parameter Table
The RICHI MZLH series Sawdust Pellet Mill can be customized according to production capacity, with the maximum capacity reaching 40T/H.
The common diameters of sawdust pellet finished products are 6/8/10mm, and the length of the pellets is generally 4-5 times the diameter.

Core Advantages
Many friends only focus on the price when purchasing equipment, but they don’t know how to judge the cost-effectiveness of a machine, thus easily falling into traps. Let’s take a look at the core advantages of this RICHI Sawdust Pellet Mill compared to similar machines on the market.
High-Quality Components, Very Reliable
The core component of the pelletizer, the ring die, is made of wear-resistant alloy steel and has undergone deep carburizing and quenching treatment, with a surface hardness reaching HRC58-62. What does this indicate? We have pushed the wear resistance of the ring die to the extreme, and its service life is even 1.5 times that of the ones on the market! The machine uses Swedish SKF bearings, and theoretically, its service life is three times that of ordinary bearings! Not to mention that there is a Siemens motor providing continuous and efficient power, and the imported oil seals that are wear-resistant and heat-resistant firmly safeguard the stability of all-weather continuous operation.
For the long run, let RICHI take the hassle out of your production.
From Operation, Production to Maintenance, Flexibility is The Key
RICHI Sawdust Pellet Mill integrates flexibility into every aspect. The equipment is equipped with a PLC intelligent control system, which allows for one-click start-up and intelligent adjustment of temperature and feeding speed, making operation extremely simple.
How flexible can the production scale be? You can adjust the ring die to the size of the pellets you want to produce. You can use it as a single machine or integrate it into a production line. Even if you want to change the wood chip formula to produce other biomass pellets in the future, it’s also possible!
The machine is modularly designed and assembled, and key parts are all detachable. In case of a malfunction, only the faulty parts need to be removed. Maintenance is quick and hassle-free!
High Output, But Also Safety
Some people may be concerned that they are running a large-scale wood pellet processing plant with a high production capacity demand. If the machine is constantly running on the production line, will there be any safety accidents? Let me tell you: Please rest assured, my friend. We attach great importance to safety production.
RICHI Sawdust Pellet Mill is equipped with a real-time monitoring system. If any key part shows signs of sub-health, it will issue an early warning.
What’s more reliable is that there is a safety interlock device next to the pelletizing chamber. In case of sudden abnormal conditions, the safety pin will immediately break, triggering the travel switch to cut off the power, and the machine will automatically shut down.
Application Scenarios
We have served many workshops and processing plants, including those producing biomass fuel, animal bedding, and organic fertilizer. All of them are suitable for using this Sawdust Pellet Mill. Here are some factories that are suitable for using it, for your reference:
Small and medium-sized wood and furniture processing plants
Just one small Sawdust Pellet Mill can help you utilize the waste from daily production. It not only keeps the factory environment clean but also allows you to use the produced pellets as fuel or sell them. It’s a win-win situation! We recommend the RICHI MZLH320 and 350 models, which have sufficient production capacity.
Local large and medium-sized wood processing plants and biomass energy plants
For these local market-oriented processing plants and dedicated biomass energy pellet plants, the requirements for production capacity and pellet quality are relatively higher. We recommend the RICHI MZLH520 and 678 series Sawdust Pellet Mills. Their powerful power systems and durable core equipment provide effective support for long-term high-load operation.
Industrial-scale biomass pellet processing centers and forestry waste comprehensive utilization bases
For large-scale wood chip pellet production bases, do you think we can only provide high-capacity single machines? Of course not. RICHI also offers complete automatic wood chip pellet production lines – from raw logs to bagged pellets. The next section will provide more details.
A Complete Wood Pellet Production Line
The Sawdust Pellet Mill is just one part of the wood pellet production line.
A complete production line should include several stages: raw material impurity removal, crushing, drying, pelletizing, cooling, screening, and packaging.
Remove Impurities From The Wood
In this step, we will use a cylindrical primary cleaner and a permanent magnetic cylinder to remove impurities such as nails and mold from the wood.
Thoroughly Crush The Wood
Use a wood splitter to cut larger wood boards and branches into 3-5 cm pieces, and then use a grinder to crush the wood pieces into 3-5 mm wood chips.
Reduce The Moisture Content of The Wood Chips
The moisture content of the crushed wood chips is usually over 30%, and it needs to be dried with a drum dryer. When the moisture content of the wood chips is around 15%, they can be pelletized.
Turn Wood Chips Into Pellets
The ring die, roller, and knife in the pelletizer work together to make the wood chips into pellets of uniform size.
Cooling and Screening
Use a counter-flow pellet cooler to cool and solidify the freshly made pellets. Then, use a rotary classifier to screen out qualified pellets and store them in the finished product silo.
Weighing, Packaging, And Sealing
The packaging scale automatically weighs and packages the finished pellets, and finally, they are sealed manually using a heat-sealing machine.
