Peanut Shell Pellet Machine
Peanut shell pellet machines transform low-density shells into high-value biomass fuel with stable performance and high output. With optional conditioning systems, the same equipment can also be adapted for feed production, offering flexible use across different industries.
What is the Peanut Shell Pellet Machine?
The peanut shell pellet machine is a high-efficiency biomass pellet making machine designed to compress loose, low-density peanut shells into high-density biomass fuel pellets. Peanut shells are abundant in agricultural production, but for a long time they have been discarded, burned in the open, or used inefficiently, resulting in resource waste and environmental pollution.
By compressing peanut shells into standardized fuel pellets, users can convert waste into high-value, environmentally friendly, and widely demanded clean energy, applicable to various fuel scenarios such as home heating stoves, industrial biomass boilers, steam systems, and biomass power plants.
During the production process, peanut shells are extruded under high pressure through a ring die. The lignin contained in the peanut shells softens under high temperature and pressure, becoming a natural binder, allowing the final pellets to be formed without any additives. The pellets are high in density, have a smooth surface, and are durable for storage. The finished pellets typically have a calorific value of 3800–4800 kcal/kg, low ash content, stable combustion, and clean emissions, making them a high-quality biomass energy source to replace traditional fuels such as coal, firewood, and diesel.
While the primary purpose of a peanut shell pellet machine is to produce fuel pellets, it can also be equipped with a steam modulator and specialized feed formulations to produce feed pellets if needed. For example, the starch curing level can be adjusted to improve palatability for different animals.
For users looking to turn agricultural waste into valuable resources and create sustainable energy benefits, peanut shell pellet mills are an ideal choice that combines efficiency, environmental friendliness, and commercial value.

FAQ
To help customers better understand the operation, configuration options, and maintenance requirements of the peanut shell pellet making machine, we have compiled a list of the most frequently asked questions. Whether you are new to biomass pellet production or planning to upgrade your existing plant, these answers will provide clear guidance and practical information to support your decision-making.
What is the required moisture content of peanut shells before pelletizing?
+
For smooth pelletizing, peanut shells usually need to be dried to a 12–18% moisture content. Within this range, the material has enough flexibility to bind well during compression, while still being dry enough to prevent slippage or die blockage. If the shells are too wet, they tend to clog the die and produce soft pellets; if they are overly dry, they become powdery and difficult to form. Proper moisture control is one of the key steps to achieving stable output and consistent pellet quality.
Can the machine also produce other biomass pellets?
+
Yes, the peanut shell pellet machine is highly versatile and can process a wide variety of biomass materials beyond peanut shells. By adjusting the ring die, roller pressure, and feeding system, it can handle rice husk, sawdust, straw, sunflower husk, palm fiber, and other agricultural residues. This flexibility allows users to produce not only fuel pellets but also mixed-material biomass pellets, expanding production possibilities and potential revenue. The machine’s robust design and optimized compression system ensure that even fibrous or low-density materials can be pelletized efficiently, maintaining consistent pellet quality across different raw materials.
