As the global focus on renewable energy and waste recycling deepens, the biomass pellet industry is developing vigorously. Rice husk pellet machine, a specialized equipment for converting rice husk waste into high-value 0.2-8T/H biomass pellets, has become a key driver in the rice-producing regions’ green economy. Beyond rice husk pellet production, the industry also relies on various specialized biomass pellet machines and integrated production lines for raw materials like wood chips, alfalfa, and EFB. Choosing the right rice husk pellet machine and matching equipment is vital for efficient, profitable operations in the green biomass sector.
Core Advantages and Working Principle of Rice Husk Pellet Machine
Rice husk pellet machines are specifically engineered for processing rice husks, which have high silica content and hard texture. They boast unique structural advantages and scientific working principles to ensure stable and high-quality pellet production.
- Key Advantages: Adopting a reinforced ring die and wear-resistant pressure roller structure, it can effectively resist the abrasion caused by rice husks’ silica content, extending the service life of core components by 40% compared to ordinary pellet machines. Equipped with a variable-frequency feeding system, it ensures uniform feeding and avoids blockages caused by rice husks’ light weight and loose characteristics. The production capacity ranges from 0.5 tons to 15 tons per hour, suitable for both small-scale rice mills and large-scale biomass energy enterprises. The produced rice husk pellets have stable density (1.1-1.3 g/cm³), excellent combustion performance, and low ash content, widely used in industrial boilers, biomass power generation, and household heating. Additionally, it realizes the resource utilization of rice husk waste, solving the environmental pollution problem of rice husk stacking.
- Working Principle: The working process of rice husk pellet machine mainly includes raw material pretreatment, extrusion molding, and pellet cutting. First, rice husks are cleaned to remove impurities such as stones and rice grains, then crushed into particles smaller than 8mm (rice husks are relatively hard, requiring fine crushing for better pelleting). The pretreated rice husks are dried to a moisture content of 10-16%—a critical factor for successful pelleting. Then, the materials are evenly fed into the pelleting chamber via the variable-frequency feeding system. Under the high-speed rotation and extrusion of pressure rollers and reinforced ring die, the materials are compressed and formed through die holes. The friction during extrusion generates heat (around 70-90°C), making the pellets firm and durable. Finally, the cutter cuts the pellets into the required length, completing the production of rice husk pellets.

Specialized Biomass Pellet Machines for Other Raw Materials
Different biomass raw materials have distinct physical and chemical properties, requiring specialized pellet machines to ensure production efficiency and product quality. Common types besides rice husk pellet machines include:
- High-quality wood pellet machine: Tailored for woody raw materials such as pine, birch, poplar wood chips, and sawdust. It adopts a vertical ring die structure with strong extrusion capacity and good heat dissipation, suitable for high-fiber woody materials. The produced wood pellets have high calorific value, widely used in industrial heating and household heating.
- Alfalfa Pellet Machine: Designed for herbaceous raw materials like alfalfa and clover. It features low-pressure pelleting design to avoid excessive damage to nutritional components, making pellets suitable for both energy use and ruminant feed. Equipped with a special feeding system to ensure stable operation.
- EFB Pellet Machine: Specialized in processing palm oil industry waste EFB (Empty Fruit Bunch). Due to EFB’s high fiber content and toughness, it is equipped with a high-torque transmission system and special die, enabling efficient crushing and extrusion into high-quality pellets.
- Grass Pellet Machine: Suitable for grassy raw materials such as pasture, hay, and crop straw. It adopts a dual-roller extrusion structure with a forced feeding device to adapt to the loose characteristics of grass, ensuring continuous and stable production.
Integrated Biomass Production Lines for Different Raw Materials
For large-scale biomass enterprises, a single rice husk pellet machine cannot meet the demand for large-volume continuous production. Integrated biomass production lines tailored for different raw materials realize automated and systematic production.
- Rice Husk Biomass Pellet Production Line: Matching rice husk pellet machines, it integrates raw material cleaning, crushing, drying, mixing, pelleting, cooling, screening, and packaging. Equipped with specialized rice husk crushers and efficient drying equipment to handle the hard texture and high moisture content of rice husks, the whole line is equipped with dust removal systems to meet environmental protection requirements. Suitable for rice processing factories and biomass energy enterprises in rice-producing regions.
- Wood Chip Biomass Production Line: Focuses on woody raw material processing, equipped with high-efficiency wood crushers and drying equipment with strong moisture removal capacity. The pelleting section adopts vertical ring die pellet machines, suitable for wood processing factories and biomass energy enterprises near forest areas.
- EFB Biomass Production Line: Customized for palm oil-producing regions, the preprocessing section is equipped with EFB special crushers and depithing equipment. The drying section adopts high-temperature rapid drying equipment to adapt to EFB’s high moisture content, with strong corrosion resistance to suit humid and hot environments.
- Alfalfa Biomass Production Line: Integrates feed and energy dual-purpose functions, with a gentle drying process to retain alfalfa’s nutritional value. The pelleting section uses low-pressure pellet machines, suitable for agricultural and animal husbandry integrated enterprises. (best site)
