Due to its unique advantages, double-roller press granulators have become essential equipment for farms to process manure and produce organic fertilizer. When selecting a granulator, you need to consider multiple factors to ensure it meets your production needs.

First, you need to determine your production scale. Small and medium-sized farms have limited daily manure processing capacity, so choosing a small machine with an hourly capacity of 1-3 tons can meet daily granulation needs while avoiding idle equipment. Large-scale farms require a machine with an hourly capacity of 5 tons or more and strong continuous operation capabilities to ensure timely manure processing and stable fertilizer output.

Second, consider the characteristics of the raw materials. Farms primarily use livestock and poultry manure as their raw material, which is high in moisture and contains impurities such as crude fiber. Therefore, the equipment needs to have strong anti-clogging capabilities, and the roller surface should be made of a non-slip and wear-resistant material to prevent slippage and affect granulation efficiency.

Supporting facilities should be planned simultaneously. It’s recommended to use pre-treatment equipment such as dewatering machines and crushers to control the moisture content of raw materials within an appropriate range, and to configure screening devices to grade finished particles to improve fertilizer quality. Furthermore, consider equipment energy consumption, prioritizing energy-efficient models to reduce operating costs.

A balance should be struck between price and after-sales service. Avoid blindly pursuing low-priced equipment, as its materials and workmanship may be defective and increase maintenance costs. Choose a manufacturer that can provide installation and commissioning, operator training, and rapid fault response to ensure stable operation after the equipment is commissioned and minimize losses caused by downtime.

A comprehensive assessment of production scale, raw material characteristics, equipment quality, supporting capabilities, and after-sales service is crucial to selecting a double-roller press granulator suitable for your farm, ensuring efficient resource utilization of manure.

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.

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.
