In the modern biofertilizer manufacturing industry, selecting the right granulation equipment has become essential for improving product quality, reducing energy use, and meeting diverse market demands. As more producers upgrade their biofertilizer production systems, three types of granulating machines have proven to be the most efficient and reliable options in 2025.
1. Double Roller Extrusion Granulator – For Low-Moisture and Energy-Saving Production
The roller compactor granulator is an ideal choice for plants producing biofertilizer pellets with low moisture content. This dry granulation technology compresses powder materials directly into uniform granules without drying or cooling steps.
Its main advantages include:
Low power consumption and compact structure
Suitable for temperature-sensitive microbial fertilizers
Easy to maintain and fully enclosed for clean operation
For manufacturers seeking a cost-effective way to produce high-strength granules, this granulator remains one of the most popular options.

2. Disc Granulator – For Flexible Control of Particle Size
The pan granulator, also called a disc pelletizer, provides better flexibility in controlling granule size and density. It’s widely used in small and medium-scale organic biofertilizer production lines, especially where raw materials like composted manure, humic acid, or peat are used.
Operators can adjust the inclination angle and rotation speed to create uniform particles. Its simple design and visual operation make it ideal for new investors and research-based fertilizer plants.
3. Drum Granulator – For Large-Scale Continuous Production
For industrial-scale biofertilizer granulation plants, the rotary drum granulator stands out for its capacity and stability. It works well for both organic and compound fertilizers, ensuring smooth particle formation through continuous rolling and coating.
Key benefits include:
High output with stable granule quality
Integration with hot air drying systems
Adaptability for NPK and microbial formulations
This type of biofertilizer pelletizing machine is commonly used in complete fertilizer production systems where automatic feeding, drying, and cooling are connected in one process.

Making the Right Choice
When choosing a granulation machine for biofertilizer production, consider your raw materials, moisture level, and output requirements. For example, dry powder lines perform best with roller extrusion systems, while organic compost mixtures benefit from pan or drum granulation.
A well-selected granulator not only improves product uniformity but also ensures higher efficiency and lower operating costs across your biofertilizer manufacturing process. If you want to buy a granulation machine, welcone to visit: https://www.biofertilizerproduction.com/
