Straw Pellet Mill
What Is a Straw Pellet Mill?
A straw pellet mill is a specialized biomass pelletizing machine that compresses agricultural straw into dense, uniform pellets through mechanical extrusion. Compared with loose straw, pelletized straw offers:
- Higher energy density
- Lower transportation and storage costs
- Improved combustion efficiency
RICHI designs each straw pellet making machine to handle fibrous, low-density raw materials while maintaining consistent pellet quality. The pellets can be used as animal feed and eco-fuel.
Models and Specifications of RICHI Straw Pellet Mill
RICHI provides multiple straw pellet machine models to match different production needs. Custom-built straw pellet presses are available for higher capacities and special straw materials. Based on your product requirements (animal feed or eco-friendly fuel), you can choose whether to install a conditioner on the standard straw pellet mill.

Core Competitiveness Of RICHI Straw Pellet Mill
We engineer the straw pellet mill for profitable biomass production. It delivers high pellet quality, stable output and long-term reliability. In this way, it helps you cut operating costs and maximize return on investment.
High Raw Material Adaptability
Our straw pellet machine can efficiently handles wheat straw, rice straw, corn stalks, and mixed agricultural residues. This adaptability ensures stable pellet production from seasonally available feedstocks, maximizing resource utilization and offering flexibility in raw material sourcing for our clients.
Durable Pelletizing Components
We manufacture the ring die and roller assembly of our straw pellet mill from high-alloy steels. In addition, we subject these components to advanced heat treatment. Thus, these core parts exhibit exceptional resistance to abrasion and fatigue. This durability cuts down long-term costs for part replacement and downtime.
Energy-Efficient Pellet Pressing
Our machine features an optimized compression ratio. This design minimizes unnecessary mechanical friction and compacting resistance. Consequently, it reduces energy consumption per ton of pellets substantially. It lowers operating costs dramatically and improves production economy.
Easy Operation & Maintenance
We design our straw pellet machine with a user-centric philosophy. For example, features like easy die replacement systems and centralized lubrication facilitate quicker servicing, minimizing operational complexity and required downtime.
Intelligent Control & Monitoring
Our straw pellet making machine comes with an advanced control system. Operators can regulate key parameters precisely, such as feeder speed and main motor load. Moreover, real-time monitoring and automated adjustments keep the production process within optimal conditions.
Precision Pellet Quality Control
The pellets produced have high density, strong mechanical strength, uniform size and low fines content. They ensure stable, efficient combustion and improved energy utilization. Meanwhile, these pellets resist breakage and mold during storage and transportation, and offer high commercial value.
How the Straw Pellet mill Works
The working principle of a straw pellet mill is a continuous process that transforms loose straw into high-density pellet fuel or pellet feed through physical compression.
First, the crushed and conditioned (e.g., moisture-adjusted) straw feedstock is fed into the pelletizing chamber. Inside, the rotating ring die drives the rollers to forcibly compress the material through the dense, regular holes on the die.
During this process, the material undergoes intense frictional heating under high pressure, causing the inherent lignin to soften and act as a natural binder.
Finally, the extruded material is cut, forming dense, smooth cylindrical solid pellets. Thereby it converts agricultural waste into standardized, clean-burning fuel — thereby converting agricultural waste into standardized, clean-burning fuel.

Wide Application Range of Straw Pellet Mill
RICHI straw pellet mill offers robust functionality and versatile performance, making it an ideal solution for diverse industrial and agricultural needs. It efficiently processes various raw materials into high‑density, uniform pellets. And the raw materials cover crop residues, grass and forestry waste.
