How to Process Compound Fertilizer Using a Rotary Drum Granulator

With the development of agriculture and technological advancements, market demand has become increasingly diversified. Rotary drum granulators have also attracted significant attention for their high efficiency, ease of operation, and excellent granulation results, making them a standout among other fertilizer granulators.

In the fertilizer production process, fertilizer granulators are crucial for determining fertilizer yield and quality. The quality of this equipment directly impacts the user’s economic benefits. During the rotary drum granulator production process, increasing the material temperature is necessary to improve the solubility of the granules. To reduce heat energy consumption during the drying process, the performance of the granulator must be effectively maintained.

To reduce production costs throughout the fertilizer production process, low energy consumption and high efficiency must be achieved at every stage of the granulation process. A high granulation rate in a rotary drum granulator ensures consistent production. To ensure this high granulation rate, the smoothness of the granulator’s inner wall must be enhanced. A smooth inner wall reduces friction, allowing the material to roll back and forth and quickly form granules. Our rotary drum granulator differs from traditional granulators. As the granulator’s lining rotates upward with the drum, it sags due to its own weight, allowing any material adhering to the lining to fall due to gravity, thus automatically removing lumps. Furthermore, this reduces the amount of water added during the granulation process, thereby alleviating the drying load during fertilizer processing.

In fertilizer production, large-scale rotary drum granulators can be equipped with two drum fertilizer screeners. The first is used to remove fines and small particles. The second drum fertilizer screener has two screen sections. One section, with a small mesh, selects particles that meet the requirements. These particles are then conveyed by a conveyor to the packaging machine. The other section, with a mesh, removes oversized particles, which are directly sent to a chain crusher for crushing before returning to the granulator.

The Important Role of Disc Granulators in Fertilizer Production Lines

In the granulation process of fertilizer production, disc granulators, with their unique structure and performance, are the preferred equipment for small and medium-sized production lines. Known as the “precision shaper” of fertilizer granules, their core advantage lies in efficiently converting powdery materials into regular granules, balancing production efficiency and product quality.

The simplicity of their structural design is a notable feature. The main body consists of an inclined disc, a transmission mechanism, and a frame. The disc’s inclination can be adjusted within a certain range, controlling the material’s residence time within the disc. This minimalist design not only reduces equipment failure rates but also facilitates routine maintenance. Compared to drum granulators, the disc granulator occupies nearly half the floor space, making it particularly suitable for production environments with limited space.

The wide range of compatible raw materials enhances its practical value. Disc granulators can be used for granulation in both organic fertilizer production lines and NPK compound fertilizer production lines. Their unique rolling granulation method reduces clumping of materials with high moisture content. For organic raw materials containing coarse fiber, they can also gradually agglomerate to form stable granules, eliminating the need for complex pretreatment. Energy and cost-effectiveness highlight competitive advantages. Compared to extrusion granulators, disc granulators consume less power and require no mold replacement, reducing equipment wear and maintenance costs. Furthermore, their stable continuous production capacity allows a single unit to meet the production needs of small and medium-sized fertilizer plants, helping companies reduce initial investment and operating costs.

Amid the development of green agriculture, disc granulators, with their high efficiency, flexibility, and cost-effectiveness, have become a crucial piece of equipment in the fertilizer forming process, providing strong support for improving fertilizer quality and promoting sustainable agricultural development.

The importance of standardized operation of the double roller press granulator

The importance of standardized operation of the double roller press granualtor is reflected in many aspects. The following is a detailed description:

1. Ensure stable operation of the equipment: Standardized operation procedures are an important guarantee to ensure the stable operation of the double roller press granulator. Operators must receive strict professional training before taking up their posts and be familiar with the structure, working principle, operation procedures and safety precautions of the equipment.

2. Improve production efficiency: Standardized operation can effectively improve production efficiency. For example, by reasonably adjusting the roller spacing and controlling the feed amount, the uniformity and molding quality of the material during the extrusion process can be ensured.

3. Extend the service life of the equipment: Regular maintenance and inspection are important measures to extend the service life of organic fertilizer equipment. Including checking the wear of key components, maintenance of the lubrication system, and detection of the electrical system.

4. Improve product quality: Standardized operation helps to improve product quality. For example, by controlling the particle size and moisture of the material, ensure that the material meets the equipment requirements and avoid the decline in the quality of particle molding due to material problems.

5. Reduce production costs: Standardized operation can reduce production costs. For example, by reasonably adjusting equipment parameters, avoid overloading of equipment, reduce energy consumption and equipment loss. At the same time, regular maintenance of equipment can reduce equipment failures and maintenance costs.

Through standardized operation, the production efficiency, product quality and equipment life of the double roller press granulator can be effectively improved, while reducing production costs and safety risks. Therefore, standardized operation is crucial to the operation of the double roller press granulator.

Requirements for the site of organic fertilizer trough compost turning machine

The organic fertilizer groove compost turning machine has the following specific requirements for the site:

1. Site selection and layout: The site should be far away from water sources and residential areas to avoid pollution to the surrounding environment. The site should have water, electricity, storage and other treatment facilities, and the ground should be hardened to prevent material leakage.

3. Ground conditions: The ground of the site should be flat and hard, and cement ground or hardened land can be selected. The ground needs to be treated with anti-seepage to prevent material leakage from polluting groundwater.

4. Supporting facilities: The fermentation site of the organic fertilizer production line should be equipped with rainproof facilities to prevent rainwater from eroding the materials. The site should have a good drainage system to ensure that the leachate can be effectively collected and stored. Equipped with automatic monitoring and control equipment to monitor parameters such as temperature and humidity during the fermentation process.

5. Material stacking: The material pile should maintain a certain shape, usually a trapezoid or triangle, to facilitate the operation of the compost turning machine. The width of the strip-type fermentation should be 2.0m-4.5m, and the height should be controlled at 1.0m-2.0m.

6. Operation and maintenance space: The site should reserve sufficient operation space to facilitate the movement and operation of the compost turner. Set up maintenance channels to facilitate daily maintenance and overhaul of the equipment.

By meeting the above site requirements, the normal operation of the organic fertilizer trough compost turner can be ensured, the compost fermentation efficiency can be improved, and the impact on the environment can be reduced.
