Material Overview
Agricultural waste refers to biomass residues generated during agricultural production and processing, including straw, rice straw, wheat straw, corn stalks, peanut shells, sunflower husks, and similar materials. These materials are widely available in major agricultural regions such as Southeast Asia, South Asia, China, Eastern Europe, South America, and Africa.
Agricultural residues are considered one of the most promising biomass resources due to their large annual output and renewability. When properly processed into pellets, they are commonly used for industrial boilers, biomass power plants, and co-firing applications.
Pellets produced from agricultural waste typically have a calorific value of 14–18 MJ/kg (approximately 3,300–4,300 kcal/kg), depending on material type, ash content, and moisture control.
Recommended Process Flow
Moisture < 15 %: Agricultural Waste → Cutting & Grinding → Pelletizing → Cooling → Packaging
Moisture > 15 %: Agricultural Waste → Cutting → Drying → Pelletizing → Cooling → Packaging
Key Equipment Configuration
Rotary Crusher
Performs cutting and grinding for low-moisture agricultural waste.
Rotary Cutter
Cutting solution for small-capacity, high-moisture materials.
Dual-Roller Shredder
Heavy-duty cutting for high-capacity agricultural waste processing.
Rotary Drum Dryer
Lowers moisture to the 10–15 % range.
Pellet Machine
Core equipment that compresses material into dense, high-quality biomass pellets.
Counterflow Cooler
Gradually cools hot pellets to improve durability and storage stability.
Packing Machine
Enables small bag or ton bag packaging according to market requirements.
Why This Solution Works
Agricultural waste varies significantly in moisture content and fiber structure. By separating process routes based on moisture level, this solution avoids unnecessary drying while ensuring stable pellet quality. Proper cutting and size reduction prevent die blockage and improve pellet density, making the system reliable for long-term industrial operation.
Processing Notes & Technical Considerations
Recommended moisture before pelletizing: 10–15%.
High ash content materials may require die and roller wear monitoring.
Stable feeding is critical for agricultural biomass pelletizing.
End Product & Applications
Agricultural waste pellets are mainly used in industrial boilers, biomass power plants, and co-firing systems. Their wide availability and cost advantages make them an important alternative fuel in many developing and agricultural economies.
