Rotary drum granulator: The art and efficiency of fertilizer granulation

fertilizer granulator Nov 15, 2025

In modern fertilizer production, the rotary drum granulator plays an indispensable role. Unassuming yet highly efficient, it transforms powdery raw materials into uniform granules, greatly facilitating fertilizer application and transportation.

In a complete organic fertilizer production line, the rotary drum granulator is often a core component. It is frequently connected to a fertilizer mixer machine. This equipment is responsible for thoroughly and uniformly mixing various raw materials, whether basic elements like nitrogen, phosphorus, and potassium, or materials rich in organic matter.

Once the uniformly mixed material enters the rotary drum granulator, the real transformation begins. As the drum slowly rotates, the fine powder particles, under suitable humidity and motion, adhere, encapsulate, and gradually grow like snowballs, ultimately forming uniformly sized granules.

The synergistic effect of this equipment is even more pronounced in the production of bio-organic fertilizers. Bio-organic fertilizer equipment is typically a system, not solely reliant on a single machine. From the fermentation and crushing of materials, to the mixing by the fertilizer mixer, and finally to the forming by the rotary drum granulator, each step is closely linked. The value of the rotary drum granulator in this process lies in its ability to effectively process organic materials, forming granules of moderate strength that are conducive to slow release into the soil.

How to adapt a BB fertilizer blender to different raw material characteristics?

fertilizer granulator Nov 15, 2025

BB fertilizer raw materials come in a variety of forms (granular, powdered, and fiber-containing). BB fertilizer blenders require targeted adjustments to accommodate these different raw material characteristics and avoid mixing problems.

For pure granular raw materials (such as urea and diammonium phosphate granules), which have relatively small density differences but are prone to rolling and stratification, the BB fertilizer blender should be equipped with guide plates within the mixer drum to guide the raw materials into upward and downward circulation and control the feed order. Adding the denser diammonium phosphate first, followed by the lighter urea, can reduce initial stratification. The speed can be appropriately reduced in the later stages of mixing to prevent excessive collisions between particles that could lead to breakage.

If the raw materials contain powdered ingredients (such as potassium chloride powder or trace element powder), a dustproof seal should be installed at the BB fertilizer blender feed port to prevent dust from escaping. Additionally, an atomizing humidifier (control the humidity to ≤15%) should be installed within the mixer drum. A small amount of humidification can enhance adhesion between the powdered raw materials and the granules, preventing dust from becoming suspended.

When the raw materials contain fiber organic fertilizer (such as fermented straw powder), it is necessary to use a paddle with a shearing function to prevent the fibers from entangled and clumping. At the same time, the fiber raw materials should be crushed to less than 3mm in advance to reduce mixing resistance. During the mixing process, the machine can be stopped and observed every 3 minutes. If fiber clumps are found, the paddle angle needs to be adjusted to enhance the shearing and dispersion effect to ensure that the fibers and granular fertilizer are fully integrated.

For fertilizer companies, choosing the right double screws compost turning machine can increase fermentation production capacity by 30% while also reducing energy consumption and labor costs.

1. Compatibility with Fermentation Tank Specifications

The operating width of the double screws compost turning machine must match the width of the fermentation tank (common widths are 3-6 meters), and the turning depth must match the tank depth. If the tank is too wide or too deep, the edge materials may not be turned properly.

2. Matching Processing Capacity with Production Capacity

Select the equipment’s processing capacity based on the daily fermentation raw material volume (a single machine can process 50-200 tons per hour). Small and medium-sized companies can choose a small machine (50-100 tons/hour). Large-scale production lines require a large double screws compost turning machine, while also allowing for 10% redundancy to account for raw material fluctuations.

3. Adaptability to Raw Material Characteristics

When processing livestock and poultry manure with high moisture content, choose equipment with spiral blades equipped with an anti-stick coating to prevent entanglement. When processing straw-like fiber materials, prefer models with a wide spiral blade spacing (15-20cm) to enhance material throwing and reduce clogging.

4. Power and Energy Considerations

Preferably choose models with variable frequency motors, which can adjust the speed based on the moisture and viscosity of the raw material. Also consider the double screws compost turning machine’s travel system. Track-type models are suitable for fixed fermentation tanks, while crawler-type models are suitable for flexible adjustments to the fermentation area.

Anaerobic fermentation: an important biological treatment technology

fertilizer granulator Nov 15, 2025

As the world seeks sustainable solutions for waste management and renewable energy, anaerobic digestion has emerged as a promising technology that addresses both challenges simultaneously. This biological process not only converts high-moisture animal manure into valuable fertilizer but also produces biogas, a renewable energy source. Particularly suitable for handling fresh manure with over 80% moisture content, anaerobic digestion offers an integrated approach to agricultural waste management.

The Anaerobic Digestion Process

The process begins with fresh manure being fed into a conditioning tank where impurities are removed. The prepared material is then pumped into anaerobic digesters, which can operate at different temperature ranges. While systems may use ambient, mesophilic (around 35°C), or thermophilic temperatures, mesophilic digestion remains the most commonly used method due to its stability and energy efficiency.

Inside the sealed digesters, anaerobic bacteria, including methanogens, break down organic matter over a period of 15-30 days. This biological decomposition generates biogas, primarily composed of methane, which can be captured and utilized for electricity generation, heating, or as vehicle fuel. The remaining materials, known as digestate, separate into solid fractions (digested solids) and liquid fractions (digestate liquid), both valuable as organic fertilizers.

Pathogen Reduction and Safety

Although anaerobic digestion operates at lower temperatures than aerobic composting, typically around 35°C in mesophilic systems, it effectively reduces pathogens through sustained microbial activity and environmental conditions. The process eliminates 85%-90% of harmful microorganisms, including pathogens and parasite eggs, while simultaneously degrading antibiotics and hormones present in the manure.

The resulting digestate products show significantly reduced levels of harmful organisms and pollutants, meeting organic fertilizer safety standards. For additional safety assurance, the solid fraction can undergo further aerobic composting, while the liquid fraction can be properly treated before agricultural application.

Advantages and Limitations

The primary advantage of anaerobic digestion lies in its dual benefit: energy recovery through biogas production and organic fertilizer generation. This makes it particularly suitable for handling high-moisture manure while reducing wastewater discharge. The technology also contributes to greenhouse gas reduction by capturing methane that would otherwise be released into the atmosphere.

However, the method has certain limitations. The pathogen reduction level is slightly lower than in aerobic composting, often requiring additional treatment of the digestate. Additionally, the technology faces challenges in processing high-fiber manures, such as poultry litter, which can cause equipment blockages and reduce system efficiency.

Anaerobic digestion represents a circular approach to agricultural waste management, transforming potential pollutants into valuable resources. As technology advances and becomes more accessible, this method continues to gain importance in global sustainable agriculture strategies, offering farmers both economic and environmental benefits while contributing to renewable energy production.

Conclusion: Integrating Anaerobic Digestion into Fertilizer Production

Anaerobic digestion serves as a crucial front-end process in the complete organic fertilizer production line, effectively handling high-moisture manure before further processing. The resulting digestate can be efficiently integrated with traditional organic fertilizer fermentation methods, where equipment like the chain compost turner or large wheel compost turner further processes the material. The large wheel compost turning machine proves particularly valuable for large-scale operations within a comprehensive bio organic fertilizer production line, ensuring thorough aeration and maturation. Finally, the processed material can be formed into uniform pellets using an organic fertilizer granulator, completing the transformation from waste to valuable agricultural input through this integrated approach that combines biogas production with organic fertilizer manufacturing.

fertilizer granulator Nov 14, 2025

Under the concept of circular agriculture, organic fertilizer production lines are quietly undergoing a transformation. They are no longer simple processing facilities, but rather a bridge for resource transformation, turning ubiquitous agricultural waste into valuable resources that nourish the land.

The entire production line begins with scientific proportioning and mixing. Here, the fertilizer mixer machine plays a central role. Through its unique structural design, it can uniformly mix raw materials of varying properties—whether it’s viscous livestock manure or dry straw powder—in a short time. This efficient mixing not only improves production efficiency but also ensures the stability of subsequent fermentation quality.

When the production line needs to meet more specific nutrient requirements, it demonstrates its strong compatibility. By introducing the proportioning concept of NPK fertilizer production lines, the system can precisely add elements such as nitrogen, phosphorus, and potassium, forming a perfect complement to organic matter. This scientific combination of organic and inorganic elements retains the advantages of traditional organic fertilizers in improving soil while compensating for their lack of rapid effectiveness.

From the turning and ventilation during fermentation, to the precise temperature control during aging, and the shaping process in granulation, each stage reflects a deep understanding of the material’s properties. The final product is not just uniform fertilizer pellets, but a commitment to the health of the land.

This modern production line is redefining the value of “waste.” It allows agriculture to return to its cyclical nature, enabling nutrients to find a new home within the ecosystem.
