Why Choose a Drum Pelletizer for Bio Fertilizer Manufacturing?

When producing high-quality biofertilizer at scale, the granulation process is essential. Among all pelletizing technologies, the drum pelletizer (also known as rotary granulator) stands out for its reliability, high output, and adaptability to various organic materials. Whether you’re expanding your production line or planning a new project, a drum pelletizer can be a game-changing investment.

1. What Is a Drum Pelletizer?
A drum pelletizer is a rotating cylindrical machine that agglomerates fine biofertilizer materials into round granules through tumbling and spraying. It is ideal for wet granulation, where materials are moistened with water or binders during the process.

The main components include:

Rotary drum (with adjustable inclination and rotation speed)

Spray system for liquid additives

Internal lifting plates for uniform material distribution

2. Why Use It for Bio Fertilizer Production?
Drum granulation machines are particularly effective in large-scale bio organic fertilizer plants for several reasons:

High Capacity: It handles large volumes (3–30 tons per hour), ideal for commercial operations.

Uniform Granules: Produces 3–5 mm round pellets with good mechanical strength.

Flexible Input: Compatible with animal manure, agricultural waste, digestate, and compost.

Low Maintenance: Simple structure, wear-resistant materials, and long service life.

3. Production Process Overview
Here’s how a typical drum pelletizer fits into your biofertilizer manufacturing line:

Fermentation: Organic raw materials are fermented to kill pathogens.

Crushing and Mixing: Materials are ground and blended with additives.

Granulation: The mixture enters the rotary drum and forms pellets under rotation and spray.

Drying & Cooling: Moist granules are dried and cooled for packaging.

Screening & Coating (optional): Unqualified particles are recycled, and final granules may be coated to prevent caking.

How Do You Make NPK Granules?

NPK Wet Granulation Technology

Wet granulation technique is one of the most commonly used methods for producing NPK granules. This process involves combining the NPK raw materials with water to form a wet mixture. The mixture is then processed through a granulator, where it is shaped into granules.

The drum granulator is a large rotating drum that applies a tumbling action to form granules, while the disc granulator uses a spinning disc to achieve the same result. Both machines are efficient and produce high-quality NPK granules. Besides, Shunxin’s NPK granulation machines are perfect for this process as they are designed to handle the wet mixture and form it into uniform-sized granules.

NPK Dry Granulation Technology

Dry granulation technology, on the other hand, is a process where the raw materials are compacted and then granulated without the addition of liquid. This method is ideal for materials that are sensitive to moisture or heat.

SX double roller granulator is perfect for NPK dry granulation. This granulator uses two rollers that press the material into a sheet or ribbon. The sheet is then broken down into granules through a process called extrusion. This roll press granulator is highly efficient and produces granules with a uniform size and shape.

When it comes to producing NPK granules, the choice between wet and dry granulation depends on the raw materials, the desired properties of the granules, and the production scale. Shunxin’s NPK granulation machines are versatile and can be used for both small and large-scale production. They are also designed with the user in mind, with easy-to-use controls and maintenance-friendly features.

In addition to the granulation machines, Shunxin also offers a range of other equipment that can be used in the production of NPK granules, including static batching machine, double shaft mixers, rotary screening machines, packing scales, and automatic palletizers. These machines work together to create a complete production line that is efficient, reliable, and cost-effective.

The Ingenious Design of the Fertilizer Rotary Drum Granulator

Introduction to Rotary Drum Granulation

Agricultural fertilizers are the unsung heroes of crop production, providing essential nutrients that enrich soil and bolster plant growth. However, the effectiveness of these fertilizers is often dependent on their form. Enter the rotary drum granulation equipment, a machine engineered to convert fine powder into uniform, round pellets. This transformation is not just cosmetic; it enhances the fertilizer’s handling, storage, and application properties.

The Heart of Granulation: The Rotary Drum

At the core of this drum granulator design is the rotary drum, a large, rotating cylinder that provides the necessary environment for granule formation. The drum’s design is relatively simple, yet it must be precisely engineered to ensure efficient and uniform granulation. The interior of the drum features flights, or lifters, which are strategically placed to promote the mixing and movement of particles as the drum rotates.

The Granulation Process: A Symphony of Science and Engineering

The rotary drum granulation process starts with the introduction of the raw fertilizer material and a binder solution into the drum. As the drum rotates, the flights lift the material and cascade it back down, creating a rolling motion that gradually builds granules through accretion. This tumbling action is the heart of the granulation process, encouraging the raw material to collide and stick together, forming small pellets. Click here to learn more.

The speed of rotation, the angle of the drum, the design of the flights, and the amount of binder all play critical roles in determining the quality and size of the granules. Engineers meticulously calculate these factors to optimize the granulation process.

Innovations in Drum Design: Maximizing Efficiency and Output

To enhance the efficiency of the granulation process, fertilizer rotary drum granulators often incorporate several innovative features:

Variable Speed Drives: By adjusting the drum’s rotational speed, operators can fine-tune the granulation process to accommodate different materials and desired granule sizes.
Rubber Linings: Reducing wear and tear inside the drum, rubber linings extend the lifespan of the drum fertilizer pellet machine and reduce maintenance downtime.
Spray Systems: Optimized spray systems evenly distribute the binder solution, ensuring a homogenous mix and consistent granule quality.

Overcoming Challenges: Sticking and Caking

One of the primary challenges in drum wet granulation is preventing materials from sticking to the drum walls or caking together. To combat this, engineers incorporate a combination of design elements:

Coating Agents: These are sprayed inside the drum to prevent sticking and reduce the formation of lumps.
Drum Slope and Speed: Adjusting these parameters helps to control the movement of material and the formation of granules.

The Output: Durable, Nutrient-Rich Granules

The resulting granules exit the drum with a robust structure that withstands handling and transportation. They also have a high nutrient content and are released slowly into the soil, providing sustained nourishment to crops. The rotary drum granulator thus plays a vital role in the efficient use of fertilizers, contributing to higher yields and more sustainable agricultural practices.

Conclusion: The Rotary Drum Granulator – Turning Potential into Growth

The fertilizer rotary drum granulator stands as a testament to human ingenuity in the service of agriculture. Its design is a blend of simplicity and sophistication, combining mechanical principles with advanced materials and control systems. As the world continues to seek sustainable food production methods, the rotary drum granulator will remain an indispensable asset in the global quest for greener pastures and bountiful harvests.
