Empty Fruit Bunch (EFB) & Other Soft Biomass Pellet Solution
Material Overview
Empty Fruit Bunch (EFB) is a major by-product of the palm oil industry, primarily generated in Indonesia, Malaysia, Thailand, and other Southeast Asian countries. Other soft biomass materials include palm fiber, coconut fiber, sugarcane bagasse, and similar fibrous residues.
These materials are characterized by high fiber content, low bulk density, and relatively high initial moisture, making proper pre-treatment essential. When pelletized, they are widely used as fuel for large industrial boilers and biomass power plants.
Pellets made from EFB and soft biomass typically have a calorific value of 14–17 MJ/kg (approximately 3,300–4,100 kcal/kg).
Key Equipment Configuration Dual-Roller Shredder Cuts long fibers and opens material structure. Rotary Drum Dryer Reduces high moisture content to pelletizing range. Hammer Mill Further refines fiber size for pellet formation. Pellet Machine Compresses cleaned wood material into dense 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 Soft biomass materials require effective fiber cutting and moisture control. Dual-roller shredding ensures sufficient fiber shortening, while controlled drying and grinding create optimal conditions for pelletizing. This combination delivers stable output and consistent pellet quality.
Processing Notes & Technical Considerations Fiber length reduction is critical for die permeability Moisture before pelletizing: 10–15% Stable feeding prevents fiber bridging
End Product & Applications EFB and soft biomass pellets are primarily used in large-scale boilers, biomass power plants, and industrial heat systems in palm oil producing regions.

Hot Product
Pellet Machine
The 8th Generation Centrifugal Pellet Machine is developed for continuous, high-load industrial pellet production, especially for wood and biomass materials with strict requirements on output stability and pellet quality.
High-precision rollers with wear-resistant alloy steel
Hardened gear reducer ensures stable power transmission
Air-cooling system supports 24-hour continuous operation
SKF imported main shaft bearings ensure stable operation
The Dual-Roller Shredder is designed for primary size reduction of bulky, high-volume materials, providing stable and controlled coarse shredding for downstream processing.
Powered by a high-torque planetary reducer and built with a fully machined heavy-duty structure, the machine delivers strong tearing force and reliable operation under continuous load conditions. It is especially suitable for materials that are difficult to handle by conventional crushers and grinders.
Applicable Materials:
Crop straw, straw bales, grass bales, and similar fibrous materials
Domestic waste and mixed solid waste suitable for mechanical shredding
Empty Fruit Bunch (EFB), palm residues, and other soft biomass materials
The High-Efficiency Hammer Mill is designed to provide stable and efficient grinding performance for biomass and wood materials used in pellet production lines.
Built with a dynamically balanced rotor and precision CNC-machined structure, the machine delivers smooth operation, reduced vibration, and consistent grinding results.
An all-round discharge design combined with easy-access maintenance structure helps improve production efficiency and reduce downtime.
For integrated operation, the hammer mill can be supplied with a complete auxiliary system, including air conveying and dust collection equipment, offering users a reliable and well-organized grinding solution.
The pellet cooler is designed for cooling high-temperature pellets after pelletizing. By adopting a counterflow cooling principle, it allows pellets to cool gradually and evenly, helping prevent surface cracking, internal stress, and excessive brittleness. This cooling process improves pellet strength, stability, and overall product quality, making the cooler an essential part of industrial pellet production lines.
The packing machine is used for final-stage pellet packaging before delivery.
According to different application and logistics requirements, the system can be equipped with jumbo bag packing scales or small bag packing scales, providing flexible packing solutions for pellet production lines.
