The rotary drum granulator is a key piece of equipment in modern organic and compound biofertilizer production lines. Known for its high efficiency and continuous operation, this machine uses wet granulation technology to turn fine powder materials into uniform, spherical granules. With strong adaptability to various raw materials—such as animal manure, composted organic matter, and NPK compounds—it is widely used in both organic and compound fertilizer industries. Thanks to its robust structure, high output (up to 10 ème), and granule hardness up to 15–20 N, the rotary drum granulator ensures stable, large-scale production with excellent pellet quality.

The basic information about drum granules making machine
The biofertilizer drum granulator is suitable for use in the process of making bio fertilizer. Rotary Granulator belongs to one of the key fertilizer granulating equipment for making biological fertilizer granules. It is applyed to both cold and heat granulation with high, medium and large scale production. It is the machine that helps in the granulation process, which granules organic materials. The drum granulator consists of a rotating drum. It can mix and agglomerate the organic materials with added nutrients and binders to form uniform-sized granules.
What is the structure of biofertilizer drum pelletizer?
Before choosing a drum pelletizer for your biofertilizer production, it's important to understand its core components. Each part plays a key role in forming high-quality granules efficiently and reliably.
You should regularly check and replace consumable parts to improve the equipment's lifespan. You can purchase accessories from local suppliers or contact YUSHUNXIN.
Working Principle of Biofertilizer Drum Granulator: What You Need to Know
The drum pelletizer adopts the wet granulation method. It works through rotary agglomeration. When the composted biofertilizer powder enters the rotating drum, it rolls along the inner wall. Under continuous rotation, the materials collide, stick, and gradually form round biological fertilizer granules. Qualified pellets exit through the discharge end, while undersized particles are separated by a screening system and returned for re-granulation, forming a closed-loop process.
Adding water or binder:
Water or a binder solution is usually sprayed inside the drum. This helps the fine powder particles bond together and reach the required size (3-10 MM). You can control bio fertilizer pellets size and uniformity by adjusting the drum's angle and speed.
This wet granulating machine is ideal for large-scale biofertilizer plants. It ensures high output, consistent granule shape, and minimal material loss during processing.
Buying high-quality biofertilizer drum pelletizer with $5,000-$15,000 from YUSHUNXIN
There are many factors that affect the price of the rotary drum granulator in the biofertilizer production project, including specifications, capacité de production, production process and other factors.
Small drum pelletizer
If you have a limited budget or are just starting to enter the biofertilizer industry, we recommend that you purchase a small drum granulator. Ça coûte $5,000-$8,000 and produces 1-5 tonnes par heure. It has less initial investment, energy consumption, and maintenance costs.
Large rotary pelletizer
For fertilizer manufacturers with sufficient funds who want to occupy the biofertilizer market, choosing a large drum granulating machine will be even more powerful. The price of this equipment sold by Yushunxin is $12,000-$15,000. Bien sûr, in addition to this, you can also contact us to customize the drum granulator.
En même temps, you can not only buy the biological fertilizer rotary granulator separately, but also choose to buy the drum bio fertilizer granulation production line. Bien sûr, the cost of the production line will be higher. Si vous êtes intéressé, Veuillez nous contacter. We can customize a suitable biofertilizer production line according to your budget.

93% taux de granulation : En plus, the drum pellets making machine has a high granulation rate up to 93% . It ensures that a vast majority of the processed material is successfully formed into high – quality biofertilizer pellets. This high efficiency not only minimizes waste but also guarantees that you produce a consistent, market – ready product.
The other equipment used in drum granulation production line
While the rotary drum granulator is the core machine for forming uniform biological fertilizer granules, a complete and efficient biofertilizer production line requires additional post-processing equipment to ensure product quality.
Fertilizer Coating Machine
To further improve the granules' appearance, moisture resistance, and storage stability, you can use the fertilizer coating machine. This machine applies a uniform layer of anti-caking agent or functional coating material onto the granule surface, preventing clumping during storage and enhancing market competitiveness.
Rotary Drum Screening Machine
Après granulation, not all particles meet the required size specifications. The rotary drum screening machine separates qualified microbial fertilizer granules from oversized and undersized materials. Oversized granules are crushed and recycled, while fines are returned for re-granulation. This process guarantees consistent particle size distribution, a key factor in fertilizer performance and user satisfaction.
The common FAQ about drum pelletizer in biofertilizer production project
What types of materials can the rotary drum granulator process?
The rotary drum granulator is highly versatile. It is suitable for processing a wide range of raw materials including animal manure, compost, déchets agricoles, urée, DAP, potassium sulfate, and other organic or inorganic fertilizers. It is especially ideal for compound fertilizer and bio-organic fertilizer production.
What If My Raw Materials of Making biofertilizer Have Low Stickiness?
Low-viscosity materials often fail to form biofertilizer granules. The rotary drum granulator solves this by allowing the addition of adhesive solutions or steam through spray systems, increasing surface stickiness. The continuous rolling and tumbling motion inside the drum enhances material contact and bonding, enabling even dry powders or coarse compost to granulate effectively.
Is it compatible with automatic fertilizer production lines?
Absolutely. Our rotary drum granulator can be integrated seamlessly with fermentation systems, mixers, screening machines, revêtements, and automatic packing units to form a complete biological fertilizer production line. YUSHUNXIN also provide layout design and full-line support.
