rice straw Pellet Machine For sale
Rice straw has long fibers and high resilience, which can significantly wear down equipment. As a result, traditional straw pelletizers face challenges in forming pellets and are prone to clogging and slippage. However, our rice straw pellet mill effortlessly resolves these issues.
We have optimized the rollers and ring die of the pellet mill to address difficult forming issues. The dual-roller structure enables superior compression of materials, thereby enhancing forming efficiency. The innovative ring die adapts to high-fiber straw, consistently achieving optimal compression ratios.
Our pelletizer has dual feed inlets, each of which is equipped with anti-clogging devices. These prevent material build-up and ensure smooth feeding. When combined with the robust pelletizing system, it consistently produces straw pellets with diameters ranging from 4 to 12 mm.

Scientific Structure Design
This rice straw pelletizer machine features several innovative designs, such as anti-clogging structures, high-efficiency press rollers and ring dies. These designs enable the machine to deliver high efficiency and energy savings.
The ring die and press roll are the wear-prone components of the rice straw pellet machine. Both parts are made of alloy material and undergo carburizing heat treatment to provide excellent wear resistance.
To enhance stability and ensure efficient, long-lasting output, we have installed multiple sets of specialized motors at critical points. These industrial-grade 8-stage Siemens motors guarantee stable, consistent straw pellet production.
01
Arch-breaking feeder
This device consists of two sets of spiral feed plates, which can ensure the smooth entry of straw material through counter-rotation.
02
Forced Feeder
A forced feeder is installed at this point to facilitate smooth feeding through the inlet and accelerate the pelletizing process.
03
cutting device
Unlike feed pelletizers, this device operates as a set. By extending the cutting intervals, it enables the production of longer pellets.
04
Exhaust Vent
This device can be used alongside a fan and cyclone to help discharge high-temperature water vapor from inside the unit.
05
Observation Port
Through this viewing port, you can monitor the granulation process in real time, helping to prevent equipment clogging.
06
Pelletizing Chamber
This section features a dual-pressure-roller structure and alloy ring die, capable of generating powerful compression effects.
Advantages of rice straw Pellet machine
Through innovative structural upgrades, this rice straw biomass pellet machine boasts multiple technological advantages. It not only enables efficient, energy-saving production but also reduces labor and material costs, helping you achieve a quick return on investment.
Working Process Of rice straw pellet machine
The granulation process is conducted under high-temperature steam at 80°C, which enables the materials to bind thoroughly. Every step is scientifically designed to ensure efficient pelletizing.
- Feeding: Powdered rice straw enter the pelletizer via an arch-breaking feeder.
- Conditioning: The material is thoroughly mixed in an environment of high-temperature steam at 80 °C.
- Extrusion: The dual pressure rollers exert intense pressure, forcing it into the apertures of ring die.
- Forming: The cylindrical material is discharged continuously from the apertures.
- Cutting: The blade inside the granulation chamber cuts them into pellets of the desired length.
If you need to produce straw feed for ruminants, it can be achieved by adding a conditioner. This will better gelatinize the material, which facilitates digestion and absorption.
Once these straw pellets have cooled to room temperature, they will stabilize into the optimal pellet structure. Subsequent screening and packaging processes can now proceed. For expedited production needs, we also offer high-efficiency cooling, screening and packaging equipment for pellets.

Frequently Asked Questions
We fully understand your concerns when selecting a rice straw pellet machine. Therefore, we have compiled the following answers specifically for you. We hope this helps you understand this equipment. Should you have any further concerns, please do not hesitate to ask us.
–
Can this rice straw pelletizer directly pelletize straw?
No. Rice straw possesses high fiber content and high moisture levels. Direct pelletization will cause equipment clogging and wear, which affects pellet formation rates. Therefore, before pelletizing, it must be shredded and ensure an appropriate moisture content.
The ideal raw material is powdered with a diameter of 3–5 mm. The moisture content must be controlled to around 15%. Once properly processed, the straw can be easily pelletized into high-quality pellets.
–
What are rice straw pellets used for?
The most common use is as fuel pellets for power plants, boilers, district heating systems and residential heating systems. This reduces energy waste and pollutant emissions, providing economic and environmental benefits.
Beyond this, mixing rice straw with forage grasses and grains can produce coarse straw feed. This is primarily used in ruminant animal feed and increases dietary fiber intake, promoting digestion and absorption.
Its excellent absorbency also makes it suitable for use as animal bedding. Naturally, straw pellets for different applications require different pellet sizes. Our pellet mills can be configured with different ring die apertures and parameters to meet production needs for all these uses.
–
What are the common sizes for rice straw pellets?
The most common diameters available on the market are 6 mm, 8 mm and 10 mm. Our pelletizer can produce straw pellets ranging in diameter from 4 to 12 mm. The typical length of the pellets is 20–40 mm. However, this pelletizer can accommodate longer pellets, up to 4–5 times the diameter.
For applications such as small boiler combustion and residential heating, we recommend pellet diameters of 6–8 mm. For industrial-grade boilers and large-scale power plants, it is best to produce pellets with a diameter of 8–10 mm.
–
Can this rice straw pellet machine handle rice straw with high ash content?
Materials with high ash content generally cause wear to equipment. However, our ring die and rollers are made from 42CrMo alloy steel and undergo carburizing heat treatment. Their surfaces feature a 2 mm-thick hardened carbide layer to significantly enhance wear resistance.
Furthermore, the die’s optimized structural design consistently achieves optimal compression ratios. Accordingly, this equipment can effectively process high-ash materials, including rice straw with an ash content ranging from 6–10%. (View YouTube)
–
What other biomass materials can the rice straw pellet machine process?
The rice straw pelletizer is designed for crop straws. Therefore, it can produce pellets from most straws and crop husks. Examples include wheat straw, corn stalks, rice husks and corn cobs. It is also suitable for mixed pelletizing of various materials.
Our flexible equipment offers excellent utilization rates, helping you achieve a quick return on investment. We also provide other specialized pelletizers. These include wood chip pellet machine, rice husk pellet machine, peanut shell pellet machine, EFB pellet machine, and others.
