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 (hingga 10 t/h), 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.

The main cylindrical body (granulation drum) rotates to agglomerate materials (organic compost, NPK powder ect.) into bio fertilizer granules. It is typically made of 304 strain steel, which corrosion-resistant. Kemudian, we designed the lifting plate to prevent biofertilizer buildup.

Rubber Liners protect the inner wall from wear and sticking. They also help reduce friction and improve granulation efficiency during material movement.

A motor and gearbox rotate the rotary drum at a controlled speed. Stable rotation ensures uniform bio fertilizer granule formation and smooth material flow.

The base frame provides support for the entire drum granulator and ensures stability during operation.

The inlet feeds composted materials into the drum, while the outlet allows continuous discharge of finished biofertilizer pellets.

Sprays water or binders onto materials to adjust moisture for granulation. It supports better pellet shaping in wet granulation. Pada masa yang sama, you can add some liquid microbial agent into biofertilizer granules by this unit!

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 Kaedah granulasi basah. 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.

3 reasons of use drum pelletizer in biofertilizer production project:

  • 1

    Large capacity ( 1-30 t/h) : The drum pelletizer excels in high – volume production, making it the top choice for large – scale biofertilizer manufacturing. Whether you're launching a new large – scale biofertilizer production project or upgrading your existing operation, this equipment delivers. It guarantees consistent, high – capacity output, with a production range spanning from 1 ke 30 tan.

  • 2
    Wide range of applications : The drum granulator offers unparalleled versatility, seamlessly adapting to both bio – organic and NPK biofertilizer granulation production lines. This can reduce the cost of bio fertilizer production effectively. Pada masa yang sama, crafted from durable 304 stainless steel with an inner rubber lining, it has high corrosion resistance, reliable performance. Selain itu, you can get different size of biofertilizer pellets by changing the rotation speed of the granulation drum and the angle of the blades.
  • 3

    93% granulation rate : Selain, 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.

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

Selepas granulasi, 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, kompos, sisa pertanian, urea, 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, Mesin salutan, and automatic packing units to form a complete biological fertilizer production line. YUSHUNXIN also provide layout design and full-line support.
