The straw used is in loose form and can be pulverized directly. Additionally, the client has purchased a dryer to dry the straw and prevent mold growth.
Korea 1-1.5 T/H straw pelletizer for carbonized pellets
This South Korean client plans to produce eco-friendly, carbon-based fuel from carbonized crop straw. Since the straw arrives from farms in bales and cannot be fed directly into the pelletizing stage, a bale breaker and a straw shredder are required. To increase the carbon yield, the client has also purchased a rotary dryer.
Denmark 2-2.5 T/H straw pellet maker for fuel pellets
The client is a biomass fuel producer that previously relied primarily on wood chips as raw material. They now plan to use wheat and barley straw sourced from nearby farms, but their existing pelletizing equipment performs poorly when processing straw. Consequently, the client wishes to purchase a pelletizing system capable of processing both wood chips and straw.
Botswana 2.8-3 T/H straw pellet making machine for cattle feed
The client plans to mix straw and hay to produce cattle feed pellets. The raw materials come in round bales with diameters of 1.0–1.5 meters, requiring bale breaking followed by grinding. Both the straw and hay have been naturally air-dried to meet moisture content requirements, allowing for direct pelleting after grinding without the need for a separate dryer.
Zimbabwe 4-4.5 T/H straw pelleting machine for Fuel
The client intends to process a mixture of wheat straw, corn stalks, and wood chips into fuel pellets using two straw pelleting machines operating in parallel. This dual-machine setup ensures production capacity; if one unit undergoes maintenance, the other can maintain partial production, thereby reducing the risk of downtime and allowing for flexible adjustments to the number of active units based on order volume.

how to make straw pellets
Producing straw pellets involves far more than just the compression molding step. Process configurations must be adjusted based on factors such as the raw material’s physical form, moisture content, and the intended use of the finished product; for instance, baled straw requires bale breaking and grinding, while high-moisture material necessitates drying. If you are setting up a straw pellet plant for the first time, we can provide a comprehensive production line solution, ranging from process design to the configuration of the entire system.

Customized Straw Pellet Production Line
1-2 T/H straw Pellet Production Line for Livestock feed
The client’s raw straw material has an initial moisture content of 40%–50%, making direct pelletizing impossible; therefore, a pre-drying stage has been incorporated. Grinding the straw into powder before drying enhances drying efficiency and reduces processing time. Additionally, the production line includes a mixing stage, allowing for the incorporation of ground corn, wheat bran, and additives into the straw to produce compound straw feed pellets with improved nutritional value.
8-10T/H Straw Pellet Production Line
The client utilizes harvested wheat and corn stalks as raw materials. These are naturally air-dried, with an initial moisture content of 10%–15% upon arrival at the plant—an ideal range for straw pelletizing that eliminates the need for additional drying. To handle the high target production capacity while distributing the load and minimizing downtime risks, we implemented a dual-stage grinding and dual-pelletizing configuration. A centralized bale-breaking system processes the raw material at the intake stage, followed by parallel grinding units that discharge into a pulverized material silo; this silo then feeds two straw pellet mills to achieve a combined finished product output of 8–10 t/h. Additionally, independent dust removal systems are installed for the bale-breaking and grinding sections to effectively control dust levels within the workshop.
(MC70%)Straw Drying & Crushing Output 5-6 T/H & 3-4 T/H Straw Pellet Production Line×2
The client’s straw feedstock arrives in round bales with an initial moisture content of 70%, with moisture management posing the greatest challenge for pelletization. First, a shared bale-breaking and shredding unit breaks apart and cuts the material. The shredded straw is then split into two equal streams and fed into two identical production lines. Each line features its own dedicated storage silo, two-stage rotary drying system, magnetic separation and grinding unit, powder storage silo, pelletizing unit, cooling and screening unit, and packaging unit. The two lines operate in parallel; they function independently, allowing for simultaneous operation or the startup, shutdown, and maintenance of a single line.

Frequently Asked Questions
What raw materials can a straw pellet machine process?
→
Wheat straw, corn stover, rice straw, sorghum stalks, alfalfa, and fresh grass can all be pelletized. However, the appropriate grinding fineness and die must be selected based on the material’s fiber content, moisture level, and impurity content.
What are the moisture requirements for the raw material? Is drying necessary?
→
It is generally recommended to control the moisture content at 10%–15% prior to pelleting. If the moisture content is too high, a dryer is required; if it is too low, moisture can be added or steam conditioning applied. The specific values depend on the raw materials and the requirements for the finished product.
Can loose straw be fed directly into the straw pellet press?
→
Depending on the model, the stable hourly output of a single EFB pellet mill is generally 0.2-4 tons. Actual output is affected by the effectiveness of raw material pretreatment, moisture content, and operational factors.
Is buying just a straw pellet mill enough? How should the complete production line be configured?
→
The pellet mill is merely one link in the process. A complete straw pellet production line consists of: bale breaker, crusher, dryer (if raw material is wet), pellet mill, cooler, screener, packaging machine, plus conveying and dust removal systems. If a customer already has the upstream equipment, purchasing a standalone machine is an option. However, for new plants, a complete line is recommended to ensure matched production capacity and better after-sales support.
What production capacity options are available for straw pelletizers?
→
RICHI provides straw pelletizers with various capacities to meet customer needs. Small-scale units are suitable for on-farm use, while large-scale equipment is designed for commercial straw pellet plants. Single-unit capacities typically range from 0.2 to over 8 tons per hour, and multiple units can be combined to increase total output. By the way, when selecting a model, it is important to base the decision on actual raw materials, daily production shifts, and finished product specifications, rather than relying solely on nominal capacity ratings.
What’s the after-sales service like? Are spare parts readily available?
→
We provide on-site installation, commissioning, operation training, and spare parts supply. We also offer a one-year warranty and regular inspection services. (view our YouTube)
