A new type two in one organic fertilizer granulator solves raw material processing challenges

fertilizer granulator Dec 5, 2025

In organic fertilizer production, the challenge of bridging the gap between “mixing” and “granulation” is often amplified by differences in raw material characteristics. The new type two in one organic fertilizer granulator, integrating mixing and granulation, solves these problems with a design more closely suited to the characteristics of the raw materials.

Its most prominent advantage is its ability to handle “dry-wet mixtures.” For example, when mixing fresh chicken manure with a moisture content of 30% with dry straw powder with a moisture content of only 12%, the fertilizer granulator, within the same chamber, first uses the staggered rotation of a spiral stirring paddle to quickly interweave and blend the dry and wet materials. Simultaneously, a built-in micro-humidification device replenishes moisture to the dry material and guides the wet material to dry, resulting in a stable moisture content of 18%-22% after mixing.

It can also precisely control the proportions when dealing with “multi-component mixtures” of raw materials. Many organic fertilizers mix 3-4 raw materials, such as mushroom residue, rice husks, and humus, to enhance fertilizer efficiency. However, the densities of these different raw materials vary greatly. The new type two in one organic fertilizer granulator can automatically adjust the mixing speed according to the density of the raw materials. It slows down the mixing of heavier materials and speeds up the mixing of lighter materials, ensuring precise proportions of each raw material.

Even “difficult-to-bind fibrous raw materials” can be handled effectively. Raw materials like rice husks and peanut shells, with a fiber content exceeding 40%, tend to be loose when mixed alone. During the mixing stage, the two-in-one model uses a built-in shearing blade to cut long fibers into short fibers of 2-3 mm, which are then thoroughly mixed with other raw materials to form a mixture of “fiber skeleton + binding component.” No additional binder is needed during subsequent granulation, and the granules achieve the required hardness.

For manufacturers planning to expand their business, some new models support future capacity upgrades without the need for a complete replacement, effectively reducing secondary investment.

Choosing the right granulator allows small and medium-sized organic fertilizer plants to reduce costs, improve efficiency, and enhance product competitiveness. The new type organic fertilizer granulator is undoubtedly a cost-effective choice.

The “Pellet Revolution” of cow dung: The recycling magic of the rotary drum granulator

fertilizer granulator Dec 4, 2025

In the core process of organic fertilizer production, the rotary drum granulator, with its unique working principle, is transforming cow dung from waste into high-quality granular fertilizer. This equipment, perfectly suited to the needs of ecological agriculture, unlocks a new path for the resource utilization of cow dung through a simple and efficient process.

First, the fermented cow dung needs to be pulverized into a uniform powder. Then, a small amount of binder and nutrient additives are mixed in a specific ratio to ensure granule formation and nutrient balance. When the mixture enters the tilted rotary drum, the centrifugal force and friction generated by the uniform rotation cause the material to tumble and agglomerate within the drum, gradually forming round and uniform granules. The entire process requires no complex chemical treatment, relying entirely on physical processes to achieve the desired shape. This preserves the organic matter and beneficial bacteria in the cow dung while avoiding secondary pollution.

The advantages of the rotary drum granulator are significant. Its large-capacity drum design is suitable for large-scale production, resulting in higher efficiency for continuous operation. It produces high-quality pellets with moderate strength, facilitating storage and transportation while preventing clumping. Furthermore, the equipment is highly adaptable to various materials, flexibly handling cow manure raw materials with different moisture levels and proportions, thus lowering the production threshold.

From an environmental burden on livestock farms to “fertile gold” for nourishing crops, the rotary drum granulator maximizes the value of cow manure. This process of transforming waste into green fertilizer not only helps solve livestock pollution problems but also injects momentum into the circular economy of agriculture.

Synergistic approach of fertilizer compaction machine and oil palm empty fruit bunch forming

fertilizer granulator Dec 3, 2025

As a fiber-rich organic waste, the key to the resource utilization of oil palm empty fruit bunches lies in their forming and processing. Fertilizer compaction machines, with their targeted structural design, have become the core equipment for unlocking the granulation challenges of this type of fibrous raw material.

From the perspective of raw material compatibility, oil palm empty fruit bunches retain a large amount of tough fibers after fermentation and decomposition. This type of material has low viscosity and is prone to entanglement. Fertilizer compaction machines optimize the cooperation between the pressure rollers and the die holes, employing a large-area contact extrusion design. This allows the fibrous material to naturally unfold and pass through the die holes in the correct direction under pressure, avoiding entanglement and jamming.

Simultaneously, during the extrusion process, the fibers intertwine to form a “net-like support structure,” eliminating the need for excessive binders. Forming can be achieved solely through mechanical force and the material’s own viscosity, reducing production costs while ensuring the environmentally friendly properties of organic fertilizer.

The synergistic advantages of the two are particularly prominent in terms of forming effect and fertilizer retention. The low-temperature extrusion process of the fertilizer compaction machine minimizes the damage to organic matter and beneficial microorganisms in the oil palm empty fruit bunches caused by high temperatures, while preserving the loose fiber characteristics of the formed granules.

Furthermore, this synergistic approach optimizes the production process. The loose structure of the oil palm empty fruit bunches reduces frictional wear within the extruder, extending the lifespan of easily worn parts. Meanwhile, the fertilizer compaction machine’s high-efficiency forming capability rapidly transforms the decomposed oil palm empty fruit bunches into regular granules, solving the problems of dust generation during transport and uneven application of loose materials.

Flat die pelleting machines: A flexible solution for processing fiber materials in organic fertilizer

fertilizer granulator Dec 2, 2025

In organic fertilizer granulation equipment, flat die pelleting machines are often praised for their adaptability and convenience, but their “flexible advantage” in processing fibrous materials is rarely mentioned. Thanks to its unique structural design, the flat die pelleting machine processes fibrous organic raw materials in a “gentle and adaptable” manner, ensuring molding efficiency while preserving the original characteristics of the material to the greatest extent.

Its “gentleness” stems from the design logic of its core structure. The large-area contact between the flat die and the pressure rollers allows for more even force distribution on the material, avoiding fiber breakage or nutrient damage caused by excessive local compression. For fibrous raw materials such as oil palm empty fruit bunch and decomposed straw, this force distribution allows the fibers to form a “net-like support structure” inside the granules, enhancing particle adhesion without damaging the physical properties of the fibers.

This “flexible processing” is also reflected in the material itself. The die orifice distribution and pressure roller speed design of the flat die pelleting machine allow the fibrous material to naturally unfold and pass through the die orifices in the correct direction during extrusion, reducing the probability of entanglement and blockage. No additional binders are needed; the material can be shaped solely by the inherent toughness of the fibers and the adhesiveness of the material.

With the increasing diversification of organic fertilizer raw materials, the “gentle and adaptable” characteristics of the flat die pelleting machine perfectly meet the needs of resource utilization of fibrous waste. It solves the shaping problem of such raw materials and endows organic fertilizer with superior physical properties and fertilizer efficacy.

Synergistic application of NPK fertilizer production lines and BB fertilizer mixers

fertilizer granulator Dec 1, 2025

NPK fertilizer production lines are crucial for compound fertilizer production. As a key piece of equipment, BB fertilizer mixers, when integrated with the production line, significantly improve overall production efficiency and product quality. NPK fertilizer production involves processes such as raw material crushing, mixing, granulation, and drying. The mixing stage directly impacts the nutrient balance of the final product, and BB fertilizer mixers are a perfect fit for this requirement.

In the production line, raw materials processed by the fertilizer crusher are delivered to the BB fertilizer mixer via a fertilizer conveyor. Upon startup, the drive system drives the mixing shaft and blades, evenly mixing nitrogen, phosphorus, and potassium, laying a solid foundation for the subsequent granulation process. Inhomogeneous mixing can result in significantly different nutrient distributions in the granulated fertilizer, impacting product quality.

The BB fertilizer mixer’s control system can be linked with the overall production line control system to synchronize parameters such as mixing speed and time, ensuring a smooth production process. After mixing, the uniform raw materials are discharged through the discharge port and sent to the granulator by conveyor. It works efficiently with subsequent equipment such as dryers and coolers to form a complete NPK fertilizer production chain, helping companies achieve large-scale, high-quality production.

Core requirements for materials processed by the new type two in one organic fertilizer granulator

fertilizer granulator Dec 1, 2025

While the new type two in one organic fertilizer granulator simplifies the organic fertilizer production process with its integrated design, it has more specific requirements regarding the adaptability of the processed materials.

Precise control of material particle size is crucial. Raw materials entering the new type two in one organic fertilizer granulator must undergo crushing and screening to ensure uniform particle size controlled within the 1-3 mm range. Large impurities or incompletely crushed lumps in the material will not only clog the equipment’s feed channel and die holes but may also accelerate the wear of internal components, affecting granulation continuity. Excessively fine powdery materials are prone to generating dust and will result in insufficient granule strength after molding.

Material moisture control is critical. The suitable material moisture content is 20%-30%, which needs to be fine-tuned based on the raw material composition. Excessive moisture content causes the material to easily clump together inside the machine, leading to a decrease in granulation rate and potentially causing die blockage. Insufficient moisture content results in a lack of viscosity, making it difficult to form through extrusion or granulation processes, and even if formed, it is prone to breakage.

The material composition ratio must be scientific. The carbon-to-nitrogen ratio of the raw materials should be maintained at 25-30:1. Avoid imbalances in the proportion of single high-nitrogen raw materials (such as poultry and livestock manure) or high-carbon raw materials (such as straw), otherwise the stability of the fertilizer effect after pelleting will be affected. At the same time, the proportion of fiber components in the material should not be too high. Excessive fiber can easily entangle equipment parts, requiring pretreatment to decompose some coarse fibers. If the raw material lacks viscosity, a suitable amount of natural binder can be added to improve the pelleting effect.

Furthermore, the material must be fully decomposed. Undecomposed raw materials may undergo secondary fermentation after granulation in the new type two in one organic fertilizer granulator, causing the pellets to expand and break, and potentially leading to seedling burn during fertilization.

A deep dive into fertilizer crusher: Structure, Principle, and Core Advantages

fertilizer granulator Nov 29, 2025

As a crucial piece of equipment in the fertilizer production process, fertilizer crushers play an indispensable role in the production of organic fertilizers, NPK fertilizers, and other fertilizers. To fully maximize their performance, a thorough understanding of their structure, operating principles, and core advantages is essential.

Structurally, a fertilizer crusher primarily consists of a crushing chamber, crushing components, a feed inlet, a discharge outlet, and a drive system. The crushing chamber provides space for material crushing. The crushing components within, such as the blades, hammers, and toothed plates, are the core components that directly act on the material. The drive system provides power to the crushing components, ensuring stable operation. Some fertilizer crushers are also equipped with a screening system to select the particle size of the crushed material to meet different production requirements.

The operating principle is based on a combination of impact, cutting, and grinding. After material enters the crushing chamber through the feed inlet, the high-speed rotating crushing components cut and grind the material. This, combined with intense collision and friction between the material and the crushing components, ultimately breaks the material into particles of the desired quality before discharging through the discharge outlet.

The core advantages of a fertilizer crusher lie in its high processing efficiency, adaptability, and ease of maintenance. It can quickly crush a variety of fertilizer raw materials, and its structural design facilitates routine maintenance and cleaning, significantly reducing production downtime and providing strong support for fertilizer manufacturers to increase production capacity.

Environmentally friendly and highly efficient: The adaptability of flat die granulators in organic fertilizer production

fertilizer granulator Nov 29, 2025

With tightening environmental policies and increasing agricultural demand for green organic fertilizers, organic fertilizer production lines are placing higher demands on the environmental friendliness and efficiency of their equipment. Flat die granulators excel in both aspects, making them a better fit for the industry’s development needs.

From an environmental perspective, flat die granulators utilize extrusion molding during the granulation process, eliminating the need for high-temperature heating and avoiding the emission of harmful gases caused by high temperatures. Simultaneously, the equipment’s robust sealing design effectively reduces dust generated during raw material transport and extrusion, minimizing the impact on the workshop environment and operator health. Furthermore, flat die granulators have relatively low energy consumption, requiring less electricity during operation compared to some high-energy-consuming granulation equipment.

Regarding efficiency, while the granulation efficiency of flat die granulators is not as high as that of large ring die granulators, its output is sufficient to meet the production needs of small and medium-sized organic fertilizer production lines. The equipment’s flexible start-up and shutdown capabilities allow for adjustments to the operating rhythm based on raw material supply and order demand, reducing wasted capacity. Meanwhile, the granulated organic fertilizer produced by the flat die granulator can slowly release nutrients when applied, improving fertilizer utilization and indirectly contributing to the high efficiency of agricultural production.

Equipment operation and maintenance for organic fertilizer production lines

fertilizer granulator Nov 28, 2025

The stable operation of an organic fertilizer production line depends on scientific equipment selection and standardized routine maintenance.

When selecting equipment, the characteristics of the raw materials should be considered first. If processing high-fiber raw materials such as straw and mushroom residue, a shearing pulverizer should be selected to ensure uniform pulverization. If the raw materials are high-humidity materials such as livestock and poultry manure, the dehydration equipment’s processing capacity should be carefully considered to avoid excessive moisture in the subsequent fermentation process.

Secondly, production capacity adaptability is crucial; the equipment’s processing capacity must match the overall production capacity of the production line. Furthermore, the level of automation should be determined based on the scale of the enterprise. Small and medium-sized enterprises can choose semi-automated equipment to control costs, while large enterprises can adopt fully automated control systems to improve production stability and management efficiency.

Routine maintenance is key to extending equipment life and reducing malfunctions. Grinding equipment requires regular inspection of tool wear and prompt replacement of severely worn blades to prevent degradation of pulverization efficiency. Fermentation turning equipment requires weekly inspection of transmission component lubrication to prevent damage due to insufficient lubrication. Fertilizer granulator molds require daily cleaning to remove residual material and prevent clogging that could affect pellet quality. The combination of scientific selection and standardized maintenance can effectively improve the operating efficiency of the organic fertilizer production line, reduce the failure downtime rate, and ensure continuous and stable production.
