In modern biofertilizer production, creating uniform and durable granules is essential for storage, transport, and application. One of the most reliable machines used in this process is the drum pelletizer, also known as the rotary drum granulator. This article breaks down how the drum pelletizer works and why it’s widely adopted in biofertilizer manufacturing.
1. What Is a Drum Pelletizer?
A drum granules making machine is a rotating cylindrical device that agglomerates fine materials into granules using wet granulation technology. Inside the drum, raw materials are continuously tumbled, moistened, and bonded into round pellets.
This type of machine is especially suitable for biofertilizers because it handles high-moisture materials well and can produce large volumes efficiently.

2. Key Advantages in Biofertilizer Production
-
Efficient Granulation: Wet granulation makes it easier to form spherical granules from organic materials like composted manure and agricultural waste.
-
Higher Granule Strength: Finished pellets typically reach a hardness of 15–20N, reducing breakage during handling.
-
Uniform Particle Size: Ensures consistent nutrient content and controlled release in the soil.
-
Large Capacity: Drum pelletizers are ideal for medium to large-scale biofertilizer granulation production lines. Click here to get the detailed capacity.
3. Adding Microbial Agents
A major feature of biofertilizer manufacturing is the use of beneficial microorganisms. These are added as liquid inoculants during granulation inside the drum. Wet mixing ensures:
-
Even distribution of microbes throughout each pellet
-
Minimal loss of microbial activity due to controlled moisture and temperature
-
Better soil performance, as each granule carries live bio-agents
4. Supporting Equipment Required
To work efficiently, the drum pelletizer is usually paired with:
-
Compost Turner: Prepares and ferments raw organic material
-
Horizontal Mixer: Mixes base material and additives before granulation
-
Rotary Dryer & Cooler: Removes moisture after granulation to extend shelf life
-
Screening Machine: Separates qualified pellets from oversize or fines
-
Packaging System: Automates bagging and sealing of final products

5. Why Choose a Drum Pelletizer?
The rotary drum pelletizer is a core component in any biofertilizer production line. It’s durable, efficient, and compatible with microbial additives. Whether you’re producing granular organic fertilizer or bio-based phosphate products, this machine provides the granulation performance needed for commercial success.
Conclusion:
If you’re building or upgrading a biofertilizer manufacturing facility, a drum pelletizer is an investment in quality, efficiency, and long-term product performance. Welcome to visit : https://www.biofertilizerproduction.com/product/drum-pelletizer-in-biofertilizer-production-project/
