How Drum Pelletizers Improve Biofertilizer Manufacturing Efficiency

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

  • You can purchase these equipment in YUSHUNXIN at favorable price.

How to Make NPK Granules?

NPK granules play a crucial role in the agricultural industry by providing plants with the essential nutrients needed for growth. NPK stands for Nitrogen, Phosphorus, and Potassium, the three key components in fertilizers. Let’s explore the different methods of producing NPK granules and highlight the advantages of each technique.

Wet Granulation Technology

Among the various methods available, wet granulation is one of the most widely used approaches for NPK granule production. This process involves combining NPK raw materials with water to form a wet mixture. The mixture is then passed through a granulator, where it is shaped into granules. Two common types of granulators utilized in this process are the drum granulator and the disc granulator.

The drum granulator features a large rotating drum that applies a tumbling action to form the granules. On the other hand, the disc pelletizer utilizes a spinning disc to achieve the same result. Both machines are highly efficient and capable of producing high-quality NPK granules. Notably, Shunxin’s NPK granulation machines are specifically designed to handle the wet mixture and shape it into uniform-sized granules.

Dry Granulation Technology

Dry granulation technology, in contrast, involves compacting the raw materials without the addition of liquid. This method is particularly suitable for materials that are sensitive to moisture or heat. SX double roller press granulator is a perfect choice for NPK dry granulation. This granulator employs two rollers that press the material into a sheet or ribbon. The sheet is then broken down into granules through a process known as extrusion. The press granulator operates with great efficiency and produces granules with uniform size and shape.

The selection between wet and dry granulation methods depends on several factors, including the characteristics of the raw materials, desired granule properties, and production scale. Regardless of the chosen method, Shunxin’s NPK granulation technlogy are versatile and capable of meeting the requirements of both small and large-scale production. These machines are designed with user-friendliness in mind, featuring easy-to-use controls and maintenance-friendly attributes.

In addition to the granulation machines, Shunxin offers a comprehensive range of equipment that can be used in the production of NPK granules.

Rotary Drum Granulator For Large Scale Fertilizer Processing

A high output rotary drum granulator is an efficient fertilizer granulating machine and it is known to be perhaps one of the most essential pieces of machinery in large-scale NPK compound fertilizer production. With the introduction of steam vapor heating, all the raw materials in the rotary drum become uniformly moist during the granulation process. In the presence of steam vapor, key chemical reactions take place.

Rotary Drum Granulator Features:

1. High successful granulation rate. The granulation rate of the drum type fertilizer granulator in the best machines can exceed 85%, so they are ideal for efficient large-scale fertilizer manufacturing.

2. As raw materials are heated and moistened by steam vapor, the moisture content of the granules produced is not as high as that in granules produced in other types of fertilizer granulation machines. The reduced moisture content of formed granules means the drying process is more efficient.

3. The inside of the rotary drum is coated in a self-cleaning non-stick material, so it easy to maintain and raw materials do not adhere to the walls of the drum during mixing.

4. Constructed from high-grade anti-corrosive materials to ensure long service life.

5. Low energy consumption making it more environmentally friendly.

6. The working process is visible, so workers can quickly identify and fix any problems that occur during granulating. Thus, the efficiency of the production line is improved.
