How to Make Ideal Biofertilizer Granules with a Disc Pelletizer
In the pursuit of sustainable agriculture, biofertilizers have garnered significant attention due to their ability to enhance soil fertility and promote plant growth without the adverse environmental impacts associated with chemical fertilizers. One of the most efficient ways to produce biofertilizers is through the use of a disc pelletizer. This equipment methodically transforms fine biofertilizer powder into uniform and dense granules, ensuring ease of application and enhanced efficacy. In this article, we will explore the critical steps involved in creating ideal biofertilizer granules using a disc pelletizer.
Understanding the Disc Pelletizer
A disc pelletizer, or pan granulator, is a type of granulation equipment commonly used in the manufacturing of fertilizers, including biofertilizers. It comprises a rotating disc that tilts at a specific angle, which can be adjusted. The inclination of the disc and the speed of rotation influence the size and uniformity of the resulting granules. The granulation process involves the aggregation of fine particles into rounded pellets under the influence of centrifugal force, bonding agents, and moisture.

Key Steps in the Granulation Process
1. Preparation of Raw Materials
Before initiating the granulation process, it is crucial to prepare the biofertilizer mixture. Typically, this involves mixing fine microbial powder with organic compost or other nutrient-rich materials. The mixture should possess adequate moisture content, usually ranging from 30% to 40%, to facilitate granulation.
2. Setting Up the Disc Pelletizer
The operational parameters of the disc pelletizer must be carefully set. Adjust the tilt angle of the disc (generally between 40 and 60 degrees) and the rotational speed according to the desired granule size. A steeper angle and slower rotation can produce larger granules, while a shallower angle and faster speed yield smaller pellets. Click here to get the machine’s specific parameters.
3. Granulation Process
Introduce the prepared biofertilizer mixture into the disc pelletizer. The rotation of the disc and the centrifugal force cause the particles to collide and adhere, forming granules. It is essential to monitor the moisture level continuously and add water or a binding agent as necessary to promote adhesion and prevent dustiness.
4. Drying and Screening
Post granulation, the biofertilizer granules need to be dried to achieve the desired hardness and stability. Utilize a drying system to remove excess moisture content. Following drying, screen the granules to ensure uniformity and remove any oversized or undersized particles, which can be recycled back to the pelletizer. In this step, you can use drum dryer, cooler, screener.
Benefits of Using Disc Pelletizer for Biofertilizers
Employing a disc pelletizer offers numerous advantages including improved handling, storage, and application uniformity of biofertilizers. Granulation enhances the commercial value of biofertilizers by producing a product that is easy to spread, dust-free, and less prone to nutrient loss during transport.

Comments Off on Raw Material Moisture Control for Stable Disc Granulation Performance
cs
In biofertilizer and organic fertilizer production, disc granulation is widely used due to its flexible operation and good control over particle size. However, one of the most critical factors affecting stable disc granulating performance is raw material moisture. Improper moisture content often leads to poor granule formation, excessive fines, or unstable pellet size distribution.
Understanding moisture control requirements is essential for anyone operating a disc granulator, also known as a pan granulating machine, disc pelletizer, or plate granulator.
Why Moisture Matters in Disc Granulation
Disc granulation relies on rolling and layering mechanisms rather than mechanical compression. During rotation, fine particles gradually adhere to each other through surface tension and capillary forces created by water.
If the raw material moisture is too low, particles fail to bond effectively, resulting in dust, weak pellets, or no granulation at all. On the other hand, excessive moisture causes material to stick to the disc surface, form oversized lumps, or collapse into slurry. Therefore, moisture balance directly affects granule strength, uniformity, and production stability in a disc granulation system.
Recommended Moisture Range for Biofertilizer Materials
For most bio organic fertilizer raw materials—such as composted manure, fermented organic waste, or bio-based powder blends—the ideal moisture content before disc granulation typically falls between 20% and 30%.
Below 18%, granulation efficiency drops sharply
Between 22%–28%, granules form smoothly and grow uniformly
Above 32%, material flow becomes unstable and difficult to control
The exact moisture window depends on particle size distribution, organic matter content, and binder usage, which is why moisture adjustment is often done gradually during operation. Learn more!

How Moisture Is Adjusted During Disc Pelletizing
In practical production, moisture control is rarely achieved by pre-mixing alone. Most disc granulating machines are equipped with water spraying systems that allow operators to fine-tune moisture during pellet growth.
Uniform spraying is critical. Local over-wetting can cause uneven granule sizes, while insufficient spraying leads to excessive recycling of fines. In larger biofertilizer disc granulation lines, moisture adjustment is often combined with material pre-conditioning using mixers or aging bins.
Interaction Between Moisture and Disc Parameters
Raw material moisture does not work independently. It interacts closely with disc angle, rotational speed, and feed rate. Higher moisture generally requires a slightly lower disc angle or slower rotation to maintain stable rolling behavior.
Operators often find that stable disc granulating performance is achieved through coordinated adjustment rather than relying on moisture control alone.
Common Moisture-Related Problems and Solutions
Unstable pellet size, high return material ratio, and poor granule hardness are often linked to moisture imbalance. Regular moisture testing, controlled spraying, and consistent raw material preparation help maintain stable operation in disc granulator-based fertilizer production lines.
Final Notes on Stable Disc Granulation
Effective moisture control is not about hitting a fixed number, but maintaining a controllable range throughout production. For biofertilizer manufacturers using disc pelletizers, mastering raw material moisture management is key to achieving consistent granule quality and long-term production stability.
