How Does a Straw Pellet Machine Work？
This equipment uses mechanical compression and extrusion to process pretreated straw into dense pellets. The pelletizing process includes feeding, compression, extrusion, cutting, and discharging.
Material enters through a wide feed inlet with an anti-bridge device. A forced feeder sends it evenly into the pelletizing chamber. The ring die and rollers continuously compress the material and push it through the die holes. Adjustable knives cut the extruded material into pellets of the desired length before they discharge from the straw pellet machine. SKF bearings and Siemens motors support the key transmission parts, providing stable power and drive for continuous operation.

Straw Pellet Machine for Different Materials
We have configured the pelletizer specifically for different raw material characteristics. As a result, it adapts well to a wide range of feedstocks.
Maschine zur Herstellung von Weizenstroh-Pellets
Wheat straw becomes particularly fluffy after grinding and tends to bridge and block the feed inlet. We have widened the feed opening and added an anti-bridge device with a variable-frequency forced feeder. The continuous pushing force solves feed interruptions and ensures stable material flow.
Maschine zur Herstellung von Maisstängel-Pellets
Corn stalks have long, elastic fibers that spring back significantly after grinding. Standard straw pellet presses struggle to compress them effectively. RICHI uses a forced feeding structure to push material continuously into the pelletizing chamber, combined with a high-compression-ratio ring die. The resulting pellets are dense and uniform.
Rice Straw Pellet Machine
Rice straw fibers are fine and light, requiring highly stable feeding. RICHI focuses on smooth, consistent operation. The variable-frequency drive precisely controls the feed speed, and the anti-bridge device prevents material buildup, ensuring uniform feeding into the chamber.
Cotton Stalk Pellet Machine
Cotton stalks are hard with a distinct stem structure. They demand high wear resistance and power from the components. RICHI equips the machine with high-wear-resistant alloy steel ring dies and rollers with a hardness of HRC50 or above. The gear drive, SKF bearings, and Siemens motors provide full power support. The straw pellet machine maintains stable operation even when processing hard raw materials.
Applications of Straw Pellet Making Machine
What type of pellets do you plan to produce with a straw pellet machine? After pelletizing, straw can be processed into biomass fuel pellets, animal feed, organic fertilizer, and animal bedding.
