The Three-Layer “Smart” Fertilizer: One Watering, Long-Term Care

fertilizer granulator Dec 13, 2025

For all plants, growth depends on two things: fertilizer and water. However, traditional agriculture faces a significant dilemma: a large portion of the applied chemical fertilizers is not absorbed by plants but is instead wasted into the environment. This not only represents a huge waste but also pollutes water and soil.

Today, a new type of “smart” fertilizer offers hope for solving this problem. It is like a carefully designed “nutrient capsule” that can intelligently control the release of nutrients and lock in moisture like a miniature reservoir.

The Dilemma of Traditional Fertilizers: Quick to Come, Quick to Go

Traditional chemical fertilizers, such as NPK compound fertilizers, dissolve rapidly. Once applied to the soil, a heavy rain or a few rounds of irrigation can wash away a large amount of nutrients. Statistics show that in ordinary fertilizers, 40%-70% of nitrogen, 80%-90% of phosphorus, and 50%-70% of potassium cannot be effectively used by crops and are directly lost.

This is like giving a thirsty person a large bucket of water; they only have time to take a few sips before most of it spills on the ground. It neither quenches thirst nor avoids waste and pollution.

Three-Layer Structure: An “Intelligent” Design with Distinct Roles

Inspired by “capsules” and “sponges,” scientists have designed a three-layer controlled-release and water-retaining composite fertilizer.

Core: The Nutrient Warehouse
The innermost part is a standard water-soluble NPK fertilizer granule, storing the core nutrients needed for plant growth.

Middle Layer: The Smart Valve (Chitosan Coating)
The core is wrapped in a layer of natural material called “chitosan,” derived from shrimp and crab shells, which is biodegradable. This membrane acts like an intelligent regulating valve, slowing down the dissolution rate of the inner fertilizer granule. It allows nutrients to be released slowly and continuously, synchronizing with the plant’s growth needs.
Outer layer: Micro-reservoirs (superabsorbent polymer)

The outermost layer is made of a superabsorbent polymer material that can absorb dozens or even hundreds of times its own weight in water. In the soil, it acts like countless tiny reservoirs, securely holding irrigation water or rainwater, reducing water evaporation and deep percolation. When the soil dries out, it slowly releases the water back to the plant roots.

                    

Multiple Advantages in One

This three-layer “smart” fertilizer combines the dual benefits of slow-release fertilizer and water-retaining agent:

Saves Fertilizer: Slow nutrient release significantly improves utilization efficiency, reducing the amount and frequency of fertilization.

Saves Water: Powerful water retention reduces irrigation demands, making it particularly suitable for arid regions.

Environmentally Friendly: The coating materials (chitosan and polymer) can degrade naturally in the soil, reducing environmental pollution.

Promotes Growth: Stable supply of water and nutrients creates a better growing environment for plants.

Experiments show that this fertilizer can absorb 70 times its own weight in water within 90 minutes and exhibits excellent slow-release properties in the soil.

Green Agriculture for the Future

This three-layer “smart” fertilizer represents an important direction in agricultural technology: achieving higher yields with fewer resources while protecting our fragile environment. It is not only a “nutrient package” for plants but also a sustainable gift to the land.

Moving from the laboratory to the fields, such innovative technologies have the potential to help farmers worldwide address challenges like water scarcity and environmental pollution, paving new paths for ensuring food security and achieving green agriculture.

From Innovation to Industry: Manufacturing the Next Generation of Fertilizers

The creation of advanced “smart” fertilizers with controlled-release and water-retaining layers begins with a sophisticated industrial foundation. The core nutrient pellet is manufactured using established npk fertilizer production technology within a complete npk fertilizer production line. This process starts with precise formulation using a npk blending machine or a bulk blending fertilizer machine. The mixed powder then undergoes fertilizer granulation via advanced npk granulation machine technology, utilizing equipment like a npk fertilizer granulator machine or a fertilizer roller press machine.

The entire npk fertilizer manufacturing process, central to the manufacturing of npk fertilizer, must ensure the production of high-quality, uniform base granules before the advanced coating can be applied. Factors such as NPK compound fertilizer production capacity and NPK fertilizer production price are influenced by the efficiency of this core granulation stage and the integration of specialized npk fertilizer machine systems. The successful industrial-scale production of these innovative fertilizers demonstrates how cutting-edge material science must be seamlessly integrated with precision manufacturing processes to deliver sustainable agricultural solutions that enhance nutrient and water use efficiency on a global scale.

Chain crusher: From equipment structure to applications in medium-hard material crushing

fertilizer granulator Dec 13, 2025

In agricultural organic fertilizer production and chemical raw material processing, selecting a suitable and efficient fertilizer crushing equipment is crucial. Chain crushers, with their excellent crushing capabilities for medium-hard materials, have become the first choice for many companies. To choose the right equipment, it’s essential to first understand the structure of the chain crusher and then determine its suitability based on your specific needs.

The chain crusher’s structure and components work together to support its stable operation: a robust steel chassis withstands impact vibrations during crushing, protecting the internal rotor assembly; the rotor’s main shaft, chain, and hammers are the core of the crushing process, directly affecting crushing efficiency; adjustable-aperture screens allow for flexible control of the output particle size to meet different production requirements; the inlet and outlet design ensures smooth material flow, while protective devices safeguard operational safety. Understanding these structural elements helps companies determine whether the equipment meets their production intensity and safety standards during the selection process.

As a high-efficiency fertilizer crusher, two points need to be considered when selecting a chain crusher: First, the characteristics of the material. If it is necessary to process medium-hard materials or materials with a certain degree of moisture and stickiness, the adaptability advantage of the chain crusher can be fully utilized. Second, the production capacity requirements. Combine the parameters such as the motor power and rotor speed of the equipment to match your own production scale. Choosing the right organic fertilizer production equipment can not only improve the efficiency of material pretreatment, but also lay a stable foundation for subsequent production processes, helping enterprises reduce costs and increase efficiency.

Double axis paddle mixers: A powerful mixing tool for efficient production across multiple industries

fertilizer granulator Dec 13, 2025

In production processes across industries such as chemicals, pharmaceuticals, food, and building materials, the uniformity and efficiency of material mixing directly impact the quality of the final product. Double axis paddle mixers, with their superior performance, have become the preferred equipment for many companies.

As a high-efficiency mixing device, it uses two independent, counter-rotating mixing shafts as its core. Through paddle-type or other types of mixing blades, it shears, crushes, and diffuses materials, easily achieving deep mixing. It is particularly suitable for scenarios requiring the mixing of high-viscosity materials and solid particles, solving the problems of uneven mixing and low efficiency associated with traditional mixing equipment.

In the fertilizer production field, NPK fertilizer production lines have extremely high requirements for material mixing precision. NPK blending machine needs to uniformly mix raw materials such as nitrogen, phosphorus, and potassium. Double axis paddle mixers, with their stable mixing effect, ensure uniform distribution of raw materials, laying a good foundation for subsequent granulation, drying, and other processes, significantly improving the quality of fertilizer products. Furthermore, it is not only an important component of fertilizer mixer equipment but can also work in conjunction with fertilizer mixer machines and other equipment, adapting to the needs of different production lines such as organic fertilizers and bio-organic fertilizers.

Beyond industrial applications, double axis paddle mixers also play a crucial role in food additive mixing and pharmaceutical raw material pretreatment. For companies pursuing high-efficiency, high-quality production, selecting suitable high-efficiency mixing equipment is undoubtedly a key step in improving production efficiency and reducing costs, injecting strong momentum into the sustainable development of the industry.

Key equipment maintenance for NPK blending fertilizer production lines

fertilizer granulator Dec 13, 2025

The NPK blending fertilizer production line is the core of compound fertilizer production. The condition of its equipment directly affects product quality and production efficiency. Proper, science-based maintenance not only cuts unplanned downtime but also significantly extends equipment life and lowers production costs.

1.Raw Material Pretreatment System

Fertilizer crushers and screening equipment are the front-end critical units. Poor maintenance here causes problems later. Check hammer heads and screen mesh wear weekly. Replace them when wear reaches one-third of the original thickness. Clean out leftover material inside the equipment thoroughly after each day’s production to prevent caking and corrosion.

2.Mixing System

The double axis paddle mixer is the heart of blending. Pay special attention to paddle wear and shaft end seal condition. Measure the gap between paddles and the mixing chamber monthly. Adjust or replace paddles if the gap exceeds 5mm. Replace seals every six months to prevent lubricant leaks contaminating the product.

3.Packaging and Conveying Equipment

Automatic packing scales and belt conveyors directly impact packing accuracy and NPK blending fertilizer production line continuity. Calibrate packing scale sensors monthly using standard weights to keep weighing errors within ±0.2%. Check conveyor idler rollers quarterly for smooth rotation. Seized rollers significantly increase motor load.

Implementing these maintenance steps can greatly reduce equipment failure rates and boost the overall efficiency of the NPK blending fertilizer production line. This provides a solid foundation for stable product quality and controlled production costs.

What Factors Affect the Quality of Fertilizer Granules?

fertilizer granulator Dec 13, 2025

When we purchase fertilizer, seeing uniform, round, and solid granules feels more reliable. The quality of fertilizer granules—including uniformity, hardness, water resistance, and nutrient stability—determines their effectiveness during storage, transportation, and application. So, what factors influence the quality of these small pellets? It primarily depends on four main aspects: raw material properties, processing parameters, equipment conditions, and post-treatment processes.

Raw Materials: The Foundation of Granule Quality

First, the moisture content of the raw materials is crucial. Moisture acts like the “binder” for the granules. If the material is too dry, particles have difficulty bonding tightly, resulting in loose, easily broken granules. If it’s too wet, the material can clump together or even clog the die holes of the equipment. Different types of fertilizer have their own optimal moisture content ranges.

Second, the particle size and distribution of the raw materials must also be uniform. Fine, even powder is more easily compacted into solid granules without gaps. If mixed with unprocessed coarse fibers or large particles, voids will form inside the finished product, leading to insufficient hardness and making them fragile.

Furthermore, the inherent binding ability and chemical composition of the raw materials are also key. Materials containing humic acid, peat, or starch have a natural “glue” effect that can enhance granule strength. Materials with poor adhesion, like urea or phosphate rock powder, require adding binders such as bentonite or molasses. At the same time, the chemical compatibility of different nutrient compounds must be considered. For example, mixing ammonium nitrogen fertilizer with alkaline fertilizer may produce gas or moisture, causing the granules to crack or powder during storage.

Processing: The Key Process Shaping the Granules

The processing stage is key to shaping the raw materials into granules. Different granulation methods yield granules with different characteristics. For instance, flat die extrusion granulation typically produces denser, harder granules, while drum granulation produces rounder but potentially less dense granules.

In extrusion-type granulators, the pressure level directly determines the compactness of the granules. Insufficient pressure results in loose granules; excessive pressure, while producing hard granules, accelerates equipment wear and increases energy consumption. The machine’s rotational speed also needs precise control—too fast shortens the material’s residence time in the die, leading to incomplete forming; too slow reduces production efficiency.

A stable feeding rate is another critical point for ensuring granule uniformity. Fluctuating feed amounts cause uneven “digestion” in the machine, producing granules of varying sizes and inconsistent quality.

Equipment and Post-Treatment: Safeguarding Quality

The condition of the equipment itself is crucial for the long-term, stable production of high-quality granules. The smoothness and wear of the die (or plate) directly affect the surface finish of the granules and the smoothness of discharge. Worn press rollers or uneven drum linings cause uneven force application, resulting in inconsistent granule density and size. Therefore, regular maintenance and replacement of wear parts are essential.

After the granules are formed, they need proper “care.” Drying is the first step, where temperature and time must be just right. Excessive temperature or prolonged drying causes granules to crack due to rapid water evaporation and leads to nutrient loss (especially nitrogen volatilization). Insufficient temperature or drying time leaves too much residual moisture in the granules, making them highly prone to moisture absorption and caking during storage. Typically, organic fertilizers are recommended to be dried at low temperatures of 60–80°C to protect organic activity.

Cooling and screening are the next steps. Timely cooling prevents hot granules from absorbing moisture, and screening removes oversized, undersized, and broken granules, ensuring uniform final product specifications. Sometimes, granules also undergo a coating process, where they are wrapped in an outer layer, such as kaolin or a polymer film. This can significantly improve their water resistance and nutrient slow-release properties.

The Science of Granule Formation: From Compaction to Coating

Achieving high-quality fertilizer granules requires precise control throughout the production process, heavily reliant on advanced npk fertilizer production technology. The method of formation is critical; dry granulation processes utilize fertilizer granules compaction in a fertilizer compaction machine, while wet granulation employs methods like drum granulation using a rotary drum granulator. The choice of technology, such as implementing a roller press granulator production line for compaction or a disc granulation production line for shaping, is a key decision in the npk manufacturing process and overall fertilizer production machine configuration.

For specialized products, innovations like a new type organic fertilizer granulator may be integrated into a comprehensive npk production line or a dedicated organic line. Regardless of the chosen fertilizer compaction or wet granulation route, the synergy between material science, precise equipment operation, and controlled post-treatment determines the final granule’s hardness, uniformity, and nutrient stability. This integrated approach ensures that the finished product meets the rigorous demands of modern agriculture for efficient, reliable, and high-performing fertilizers.

Conclusion

The creation of a high-quality fertilizer granule is the result of precise control and systematic management. From the accurate formulation and pretreatment of raw materials, to the optimization of processing parameters, followed by proper equipment maintenance and strict post-treatment, every step is interconnected and collectively determines the final product’s quality. Understanding these factors not only helps producers enhance product competitiveness but also provides users with a better basis for selection.

Through continuous innovation and improvement, this technology will provide more efficient and economical solutions for global material handling across various industries, promoting continuous improvement in production efficiency and resource utilization rates.

Efficient Material Flow in Modern Fertilizer Manufacturing

Efficient material handling systems, such as loader feeding hoppers, are vital for connecting the various stages of modern fertilizer production. In a complete npk fertilizer production line, raw materials must be precisely transported to equipment like the npk blending machine for formulation. Similarly, in an organic fertilizer production line, prepared compost from a windrow composting machine needs to be moved to the granulation stage. This seamless logistics support is a key aspect of professional fertilizer manufacturing equipment integration.

The heart of production is fertilizer granulation technology, encompassing various fertilizer granulation processes. The blended material is then shaped by specialized granulators. Equipment choices vary: a disc granulator for shaping spherical pellets is central to a disc granulation production line, while a double roller press granulator forms the core of a dry roller press granulator production line. For specialized products like a bio organic fertilizer production line, the process includes additional microbial treatment. This integration of efficient bulk handling with precise, advanced granulation equipment—from disc granulator machine systems to roller presses—ensures a smooth, continuous workflow for producing high-quality fertilizers at scale.

OPEFB: From Waste to Valuable Resource

fertilizer granulator Dec 13, 2025

Oil palm empty fruit bunch (OPEFB), as the main by-product of the palm oil industry with an annual global production exceeding 100 million tons, was once considered difficult-to-manage waste. However, with technological innovation and the widespread adoption of sustainable development concepts, OPEFB is being transformed into valuable resources through various technological pathways, demonstrating significant economic and environmental benefits.

Energy Utilization: Addressing Regional Energy Demands

In the energy sector, OPEFB demonstrates enormous potential. Biomass power generation technology uses OPEFB as fuel for electricity generation, with each ton of raw material producing 800-1000 kilowatt-hours of electricity. This technology is particularly suitable for establishing captive power plants in palm oil plantation areas, addressing both waste treatment issues and local energy needs. The application of circulating fluidized bed combustion technology significantly improves combustion efficiency, with ash utilization rates reaching above 90%.

Biomass gasification technology offers another energy solution. Synthesis gas produced from pyrolyzing OPEFB in oxygen-deficient environments can be used for power generation, heating, or as chemical raw materials. Compared to traditional power generation technologies, gasification technology reduces investment costs by approximately 40%, making it particularly suitable for small to medium-scale projects. These energy utilization pathways not only create economic value but also provide feasible approaches for palm oil producing regions to achieve carbon neutrality goals.

Fertilizer Utilization: Promoting Sustainable Agriculture

Converting OPEFB into organic fertilizer represents the most direct resource utilization method. Through microbial fermentation technology, lignocellulose in OPEFB is decomposed and transformed into fertilizer rich in organic matter and nutrients. Optimized production processes can shorten the fermentation cycle to 25-35 days, with product organic matter content reaching above 50%. This organic fertilizer is particularly suitable for tropical crop cultivation, effectively improving soil structure and increasing crop yields.

Biochar production represents another high-value-added fertilizer utilization pathway. Biochar produced from pyrolyzing OPEFB under oxygen-deficient conditions not only improves soil physical properties but also serves as a carbon sequestration product participating in carbon trading. Each ton of biochar can sequester 1.5-2 tons of carbon dioxide, providing practical solutions for addressing climate change.

Material Utilization: Creating Industrial Value

In the material field, OPEFB’s application prospects are equally broad. Artificial board production technology transforms OPEFB fibers into building materials like particleboard and fiberboard, with product performance meeting international standards and costs approximately 25% lower than traditional wood-based panels. This wood-alternative resource utilization approach helps reduce deforestation and protect ecological environments.

Biomass composite material technology combines OPEFB fibers with plastics to create environmentally friendly composite products. These materials can be applied in various fields including outdoor flooring and automotive interiors, demonstrating good degradability in natural environments. Pulp production technology transforms OPEFB into packaging materials and household paper, providing sustainable raw material choices for the packaging industry.

Global Significance and Development Prospects

The multi-pathway utilization technologies for OPEFB not only address the waste treatment challenges of the palm oil industry but also make important contributions to global sustainable development. These technologies transform what were once environmental burdens into economic resources, achieving true circular economy models.

As global emphasis on sustainable development and carbon neutrality goals continues to increase, OPEFB utilization technologies will continue to develop and improve. In the future, the combination of technological innovation and market demand will enable OPEFB to play greater value in multiple fields including energy, agriculture, and materials, providing important support for building more sustainable production and consumption patterns.

Integrating OPEFB into Modern Organic Fertilizer Systems

The transformation of Oil palm empty fruit bunch (OPEFB) into valuable soil amendments is a prime example of circular organic fertilizer manufacturing. Utilizing the fibrous oil palm empty fruit bunch composition, the process begins with an efficient organic fertilizer fermentation process. This is enhanced by modern fermentation composting technology for organic fertilizer, which often employs specialized equipment like the chain compost turning machine or large wheel compost turning machine to optimize the organic fertilizer fermentation through effective fermentation composting turning technology.

Following complete stabilization, the mature compost is integrated into a complete organic fertilizer production line. For enhanced functionality, this can be configured as a bio organic fertilizer production line that includes microbial inoculation. A key piece of equipment in this line is often a new type two in one organic fertilizer granulator, which efficiently mixes and shapes the material into uniform, market-ready pellets. This integrated approach demonstrates how agricultural by-products can be systematically converted through biological decomposition and precision engineering into high-quality fertilizers, supporting soil health and sustainable agricultural practices while addressing waste management challenges.

Fertilizer Wet Granulation: The Granular Revolution for Efficient Agriculture

fertilizer granulator Dec 13, 2025

In the fertilizer production sector, wet granulation technology is becoming a key process for enhancing fertilizer quality. This technique transforms fine powders into uniform granules using liquid binders, improving not only the physical characteristics of fertilizers but also offering numerous advantages for modern agriculture. This article systematically introduces the core features, pros and cons, and unique value of wet granulation in fertilizer production.

Unique Advantages of Wet Granulation

The most notable advantage of wet granulation is its ability to produce granules with high strength and excellent uniformity. These granules are less prone to breakage during transportation and mechanical application, ensuring fertilizer integrity and effectiveness. For compound fertilizers, this technology is particularly suitable for handling multi-component powder mixtures, effectively preventing segregation of ingredients with different densities during storage and transportation, thus guaranteeing balanced nutrient content in each granule.

Regarding safety production, wet granulation significantly reduces dust generation, which not only improves the production environment and safeguards workers’ health but also minimizes raw material waste and environmental pollution. Granulated fertilizers are also cleaner and more convenient to use, especially suitable for large-scale mechanized fertilization operations.

Process Challenges and Considerations

Despite its obvious advantages, wet granulation also faces some challenges. First is the process complexity: the entire procedure requires multiple steps and various equipment working in coordination, including mixing, granulation, drying, and screening, placing higher demands on production management and equipment investment.

Secondly, production costs are relatively high, as it requires not only binders and solvents but also significant energy consumption during drying. For certain moisture-sensitive nutrients, such as some nitrogen fertilizers, wet granulation may pose degradation risks, necessitating process optimization to control temperature and humidity. Additionally, the longer production cycle is another factor to consider, especially in production scenarios requiring quick turnaround.

Wet vs. Dry Granulation: Choosing the Technical Path

Compared with dry granulation, wet granulation differs fundamentally in several aspects. Dry granulation mainly relies on mechanical pressure to bond powders, requiring no liquid binders, making it particularly suitable for moisture-sensitive raw materials. However, granules produced by dry methods generally have lower strength, are more brittle, and prone to breakage during subsequent handling.

Wet granulation, on the other hand, forms stronger inter-particle bonds through liquid binders. Although the equipment system is more complex, it has a broader application range, capable of processing more types of raw materials and complex formulations. For the fertilizer industry, the advantages of wet granulation in terms of granule strength, uniformity, and formulation flexibility make it the preferred technology for high-quality compound fertilizer production.

Special Value in Fertilizer Production

Fertilizer wet granulation is not merely a physical processing step; it is also an important means to enhance fertilizer efficacy. By controlling granule size and density, the dissolution rate of fertilizers can be regulated, achieving controlled nutrient release and improving nutrient use efficiency. Simultaneously, granulated fertilizers are easier to coat, providing a foundation for developing multifunctional, intelligent fertilizer products.

In terms of sustainable development, wet granulation indirectly reduces the risk of agricultural non-point source pollution by minimizing dust emissions and increasing fertilizer efficiency. With the advancement of precision agriculture and green farming, wet granulation technology will continue to evolve, making greater contributions to global food security and environmental protection.

Integrated Fertilizer Production: From Organic Decomposition to Precision Granulation

Wet granulation represents a specific branch of advanced fertilizer granulation technology, often used within a npk fertilizer line for high-quality compound fertilizers. This NPK fertilizer production technology relies on sophisticated fertilizer production machine systems. However, fertilizer manufacturing encompasses diverse pathways. For organic production, the process begins with the organic fertilizer fermentation process, optimized by fermentation composting technology for organic fertilizer using specialized fertilizer making machine equipment. Key equipments required for biofertilizer production include turners like the trough-type compost turner, large wheel compost turner, chain compost turning machine, and windrow compost turner to implement efficient fermentation composting turning technology within a trough-type aerobic fermentation composting technology framework.

Following stabilization, the material is processed. For granulation, systems like a disc granulation production line are used, where a disc granulator for shaping transforms the compost into pellets. This organic line may be preceded by a multiple silos single weigh static batching system for precise raw material mixing. The entire workflow—from initial pre-composting processing equipment through biological decomposition to final shaping by a fertilizer granulator like a disc granulator—demonstrates the integration of biological and mechanical engineering to produce diverse, high-quality fertilizers that support sustainable and precise agriculture.

As the rotary discs turn, the art of fertilizer formation unfolds

fertilizer granulator Dec 13, 2025

At large-scale fertilizer production sites, the large wheel compost turning machine is undoubtedly a unique sight. Unlike precision granulation equipment that focuses on shaping each individual particle, it silently plays a fundamental yet crucial role with its massive scale and repetitive rotation.

Its working scene is full of power. The huge rotating discs penetrate deep into the material pile, slowly but powerfully mixing, crushing, and oxygenating the fermenting raw materials through slow, forceful turning. This process, seemingly rough, actually lays a solid foundation for subsequent fine processing.

Once the raw materials have completed this “warm-up,” they undergo a transformation. At this point, the rotary drum granulator begins to display its charm. Inside the inclined drum, the material is continuously lifted and scattered as the drum rotates, gently tumbling and colliding, and then coagulating into round granules through its own hydration force.

For scenarios requiring specific shapes or more complex formulations, the flat die pelleting machine offers another approach. It uses a die to forcefully compress the material, producing cylindrical granules with uniform particle size. This method is highly adaptable to various materials and produces high-density finished products, making it possible to meet diverse agronomic needs.

From the macroscopic preparation by the large wheel compost turning machine, to the dynamic pelletizing by the rotary drum granulator, and then to the precise shaping by the flat die pelleting machine, this is not simply a list of equipment, but a tightly linked process chain. Each component performs its specific function, working together to transform raw powder or waste into granules of commercial organic fertilizer that are easy to transport, store, and apply.

The new type two in one organic fertilizer granulator solves your granulation challenges

fertilizer granulator Dec 13, 2025

In organic fertilizer production, many manufacturers often face problems such as large equipment footprint, high material loss, and insufficient efficiency. The emergence of the new type stirring tooth-drum granulator (new type two in one organic fertilizer granulator) provides a solution to these pain points.

The biggest advantage of this equipment is its integrated “mixing + granulation” design. In traditional production, the mixer and granulator operate separately, resulting in at least 30% more space occupied and material loss rates as high as 5%-8% during material transportation. The wet continuous push-rod granulator, with its patented technology, eliminates the intermediate conveying process, reducing material loss to 1%-2%. A single unit can produce 1-5 tons of granules per hour, increasing efficiency by 20%-40% compared to traditional equipment, making it particularly suitable for small and medium-sized manufacturers to achieve intensive production.

It also boasts strong adaptability. Whether processing livestock and poultry manure, crop straw, edible mushroom residue, or municipal sludge and other organic waste, it can easily handle them. High-viscosity raw materials can be granulated into 1-6mm particles using the mixing granulation method, while high-fiber materials can be processed using the roller pressing granulation method. The resulting granules have a sphericity of over 85% and moderate strength, making them convenient for mechanized fertilization and allowing for natural decomposition in the soil.

Even more noteworthy is that, as a low-energy-consumption organic fertilizer granulator, its energy consumption per unit of product is 15%-25% lower than traditional production lines, and it also reduces the number of operators required. At the same time, it transforms environmentally polluting organic waste into valuable resources, contributing to both environmental protection and profitability.

If you are struggling with organic fertilizer production efficiency, costs, or environmental issues, consider learning more about this integrated mixing and granulation equipment; it may bring a new breakthrough to your production.
