Written by fertilizer production line on November 15th, 2025. Leave a comment

On the stage of organic fertilizer production, the double roller press granulator is showcasing its unique value in a low-key yet highly efficient manner.

Walking through the fermentation zone, you’ll see a windrow compost turning machine working methodically. It continuously turns and aerates the mixture, preparing fully decomposed raw materials for subsequent processes. These materials are then transported to the next stage.

Here, the double roller press granulator begins its performance. Without high-temperature heating or the addition of binders, it directly compresses powdery materials into uniform granules through two precisely matched rollers. The entire process is clean and efficient, with a satisfactory granule formation rate and uniform particle size for easy packaging and application.

This granulation method represents the development direction of new type organic fertilizer granulators, pursuing lower energy consumption, a simplified process, and more stable quality. Under the extrusion of the rollers, strong molecular bonding forces are generated between the raw material particles, forming robust granules that ensure the product is not easily broken during transportation and storage.

Modern bio-organic fertilizer equipment emphasizes the continuity and automation of the production process, and the double roller press granulator perfectly embodies this concept. Its simple structural design, convenient operation, and seamless integration with upstream and downstream processes provide a reliable guarantee for the production of high-quality bio-organic fertilizer.

From the fermentation preparation by the windrow compost turning machine to the precise molding by the double roller press, and then to the subsequent finishing processes, these devices together constitute the complete picture of modern organic fertilizer production.

Rotary drum granulator: The art and efficiency of fertilizer granulation

Written by fertilizer production line on November 15th, 2025. Leave a comment

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?

Written by fertilizer production line on November 15th, 2025. Leave a comment

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.

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.

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.

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.

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.

In the fields, a quiet revolution is underway. It’s unassuming, yet undeniably enhancing soil vitality. At the heart of this transformation is a seemingly ordinary yet crucial piece of equipment—the new type organic fertilizer granulator.

The core of this equipment lies in its efficient shaping of fermented organic materials. Without complex principles, its unique mechanical design produces uniform, firm granules. These granules possess good compressive strength, are not easily broken, and are easy to transport and store.

Granulation is not an isolated step. In a complete bio-organic fertilizer production line, it occupies a critical downstream position. Before this, the raw materials typically undergo a fermentation stage. This is where the windrow compost turning machine demonstrates its value—it slowly moves across the compost pile, regularly turning it to evenly supply oxygen to the material, promoting a stable and efficient fermentation process.

The changes brought about by granular fertilizer are tangible. It effectively reduces dust during application, improving fertilization precision. The granules slowly release nutrients into the soil, increasing fertilizer utilization. For growers, lightweight and standardized packaging also makes handling and storage easier.

The significance of this new type organic fertilizer granulator lies perhaps in its ability to make the use of organic fertilizer simpler and more efficient. Working in conjunction with equipment such as windrow compost turning machines, it forms a modern bio-organic fertilizer production line, allowing organic waste to return to the land in a more dignified way, completing the cycle of matter.

How organic fertilizer production lines transform waste into fertile soil “Gold”?

Written by fertilizer production line on November 14th, 2025. Leave a comment

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.

How should a windrow compost turner be adjusted for different organic fertilizer raw materials?

Written by fertilizer production line on November 14th, 2025. Leave a comment

Organic fertilizer raw materials vary greatly, such as straw, chicken manure, mushroom residue, and distiller’s grains, and their properties can vary greatly. When using a windrow compost turner, a few adjustments can ensure smoother fermentation.

If you’re turning dry straw, it’s fluffy and porous, but it’s prone to “lifting.” The blades of a windrow compost turner tend to only scrape the surface, failing to thoroughly turn the bottom. In this case, you can steepen the blade angle to allow it to penetrate deeper into the pile. At the same time, slow down the compost turner’s speed to 2-3 kilometers per hour. This ensures that both the top and bottom of the straw pile are turned loosely, breaking up any large clumps and facilitating subsequent fermentation.

If you’re turning wet, sticky raw materials like chicken manure and pig manure, they tend to clump and stick to the blades, and the pile may become compacted after turning. At this time, the blade angle should be adjusted to a gentler angle to reduce sticking, and the forward speed can be increased slightly to allow the turned manure pile to quickly disperse and breathe. Additionally, before turning the pile, sprinkle some dry sawdust on the surface. This will automatically mix the material as the compost turner turns, reducing moisture and preventing clumping.

When turning fine ingredients like mushroom residue and distiller’s grains, the main concern is “missing” them. If the pile is too loose, they can easily leak through the gaps between the blades. By reducing the blade spacing on the windrow compost turner and maintaining a moderate speed, the fine ingredients can be turned over, ensuring even mixing and accelerating fermentation by about 10 days.

Common drum fertilizer dryer failures and solutions

Written by fertilizer production line on November 14th, 2025. Leave a comment

Drum fertilizer dryers operate frequently during the fertilizer drying process. Improper operation or untimely maintenance can easily lead to problems such as uneven drying, decreased efficiency, and equipment blockage, directly impacting production progress.

Uneven Moisture Content of the Material After Drying

One problem is large fluctuations in hot air temperature, resulting in uneven heat transfer. Another problem is that the feed rate fluctuates, resulting in uneven material accumulation thickness within the drum. To address this, first stabilize the heating system and control hot air temperature fluctuations within ±5°C. Then, use a variable frequency feed valve to control uniform feed and ensure a stable material thickness within the drum.

Sudden Drop in Drying Efficiency

This is often caused by severe wear of the drum’s internal lifter plates or dust accumulation and blockage in the hot air ducts. To address this, stop the drum fertilizer dryer and inspect the lifter plates. If wear exceeds 1/3, replace them. Clean dust from the hot air ducts to ensure the hot air volume meets the standard. Furthermore, if the drum’s exterior is scaled, perform regular acid cleaning to improve heat transfer efficiency.

Drum Blockage

This is mainly caused by the drum tilt angle being too small or residual material hardening and clumping at the discharge port. In this case, the drum fertilizer dryer should be stopped to clean the accumulated material inside the drum. Subsequently, the drum tilt angle should be adjusted to 4°-5°. After each production run, the discharge port should be thoroughly cleaned of any residual material to prevent hardened material from clogging.
