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.

In the contemporary fertilizer industry, the importance of efficient granulation technology remains undeniable. Mineral-based fertilizer processing involves unique challenges, as raw materials from various rock, mine, and ore sources differ greatly in composition, particle size, and moisture content. For manufacturers seeking consistent, high-quality mineral fertilizer pellets, the choice of granulation equipment, especially disc granulators (also known as pan granulators or disc pelletizers), proves critical. This article explores the necessity of pan pelletizers in mineral fertilizer production, focusing on typical raw materials and relevant machinery.
Which Raw Materials Suit Mineral Fertilizer Production and What Are the Industry-Specific Requirements?
Mineral fertilizer production uses a broad spectrum of rock and ore-based materials. Common examples include phosphate rock (for rock phosphate fertilizer production), potash ore, limestone, dolomite, and gypsum. Additionally, mine waste or mineral tailings from metal mining can become valuable raw materials in specific fertilizer manufacturing lines, such as mine waste management for sustainable agriculture and environmental protection.
Each industry sector has particular needs. For example, limestone fertilizer production solutions require finely milled rock with specific purity, while NPK fertilizer manufacturing depends on a reliable supply of mineral nutrients in granular form. In bulk fertilizer blending plants, the demand focuses on uniform granule size and consistent nutrient distribution. The mining industry also emphasizes cost-effective reuse of mineral residues, aligning with global environmental concerns. As a result, the right granulation technology must handle diverse minerals, adjust to varying feedstock properties, and produce stable, transport-friendly fertilizer particles.

How Do Disc Granulators Optimize the Mineral Fertilizer Granulation Process?
Disc granulating machines serve a central role in mineral fertilizer granule preparation. These pan granulators stand out because of their adaptability to a wide range of mine-based raw materials. With adjustable inclination angles and rotational speeds, disc pelletizers enable precise control over the granulation process. Operators can optimize moisture content, granule hardness, and particle size through simple setting adjustments. Compared to other machines, disc pelletizers manage both fine mineral powders and coarser ore fragments efficiently.
Disc granulators also offer excellent mixing and uniformity, ensuring each fertilizer granule contains a consistent blend of nutrients. As a result, the final product meets strict quality standards for both domestic and international markets. In rock phosphate fertilizer production, for instance, disc pelletizing helps bind powdery phosphate ore into dust-free, easy-to-handle granules. Additionally, pan granulators can function within compact production lines, minimizing space and investment requirements for mineral fertilizer manufacturing facilities.
What Other Machines Assist the Mineral Fertilizer Pellet Production Chain?
In addition to disc granulation machines, mineral fertilizer manufacturing procedures often employ ore fertilizer crusher machines (such as jaw rock crushers or raymond mills) for raw material preparation. These crushing machines break down large ore lumps, ensuring suitable particle size for efficient granulation. After granulation, screening machines classify pellets by size, removing undersized fines and oversize lumps to improve product uniformity. In the case of mineral organic fertilizer production lines, further blending and coating equipment may integrate additional nutrients or protective layers onto the granule surface, enhancing fertilizer performance.
By combining these specialized machines, manufacturers can address the full range of mineral raw materials and deliver high-quality fertilizer granules tailored to each application.
Why Should Manufacturers Prioritize Disc Granulator Selection for Mineral Fertilizer Processing?
The choice of granulation technology determines operational efficiency, product quality, and cost control. Disc pelletizers provide unmatched versatility for mineral ore-based fertilizer manufacturing. Their simple structure, low energy consumption, and adaptability to different rock or mine-derived materials make them essential in modern fertilizer production lines. Whether the requirement is for limestone granules, NPK particles, or recycled mineral waste pellets, the pan granulator ensures consistent, reliable results.
