The granulation method of fertilizer processing by disc granulator

fertilizer granulator May 14, 2025

The disc granulator is a classic and unique presence in the field of organic fertilizer granulation, and its granulation method is full of clever application of physical laws.

When the disc granulator starts, the disc begins to slowly rotate. The pre treated organic fertilizer material is evenly distributed onto a rotating disc. Under the combined action of centrifugal force, frictional force, and gravity, materials begin to gather at the edge of the disc. As the disc continues to rotate, the material keeps rolling, just like a lively ‘dance’.

During this process, the newly added material continuously adheres to the existing small particles, like rolling snowballs, and the particles gradually grow and form. In order to better shape the particles, sometimes an appropriate amount of binder solution is sprayed into the disc. Adhesive is like a magical glue, enhancing the viscosity between materials and accelerating the aggregation of particles.

The unique granulation method of the disc granulator creates its distinctive characteristics in producing granules. The organic fertilizer particles produced have a rounded shape and relatively uniform size. Round particles have obvious advantages in the fertilization process, as they can pass through various fertilization equipment more smoothly and reduce the problem of clogging. And it is more evenly distributed in the soil, which is conducive to the balanced absorption of nutrients by crop roots.

This granulation method also has a certain degree of flexibility. Operators can precisely control the size and strength of fertilizer particles by adjusting parameters such as the rotation speed of the disc, the rate of material addition, and the amount of binder sprayed. For example, increasing the disk speed appropriately can make the material move more vigorously on the disk, which helps to form smaller particles; Increasing the spraying amount of adhesive can improve the strength of particles.

The granulation method of the disc granulator is simple and intuitive, and the equipment structure is relatively simple. This not only reduces the manufacturing cost of the equipment, but also makes operation and maintenance more convenient. For many small and medium-sized organic fertilizer production enterprises, it is a cost-effective choice. With this unique granulation method, the disc granulator has always occupied an important place in the field of organic fertilizer production.

Performance characteristics of disc granulator and drum granulator for granulation

fertilizer granulator May 14, 2025

On the stage of organic fertilizer production, both disc granulators and drum granulators are highly anticipated “protagonists”, each contributing to organic fertilizer production with their unique performance characteristics. Now let’s compare these two granulators in depth.

From the principle of granulation, a disc granulator is a device that allows materials to roll and aggregate into granules on a rotating disc through the clever combination of centrifugal force, friction, and gravity. The rotary drum granulator, on the other hand, places materials in a rotating drum and achieves particle formation and growth through mutual collision, friction, and the action of binders between the materials.

In terms of particle quality, the pellets produced by the disc granulator have a rounded shape and relatively uniform size, which makes the fertilizer more evenly distributed in the soil and beneficial for crops to absorb nutrients. However, its particle strength is relatively limited. The shape of the particles produced by the rotary drum granulator is not very regular, but the internal structure is tight and the strength is high. It is more resistant to external damage during storage and transportation, reducing the occurrence of breakage and pulverization.

In terms of raw material adaptability, the disc granulator has strict requirements for the humidity and viscosity of the raw materials. Only within the appropriate humidity and viscosity range can granulation be carried out smoothly. The rotary drum granulator exhibits a more “tolerant” performance, able to adapt to various humidity and viscosity of raw materials, and has good processing capabilities for organic materials from different sources.

In terms of production efficiency, the disc granulator has a simple structure, easy operation, and can achieve continuous and stable production, making it suitable for large-scale production operations. The rotary drum granulator also has high production efficiency. The large capacity design of the rotary drum allows it to process a large amount of materials per hour, but the maintenance of the equipment is relatively complex.

In terms of energy consumption, the main energy consumption of the disc granulator lies in the rotation of the disc, which has relatively low energy consumption. Due to the large volume of the rotary drum and the need for continuous rotation, the energy consumption of the rotary drum granulator is relatively high.

In terms of investment cost, the price of the disc granulator is relatively affordable, making it a good choice for enterprises with limited funds. The price of drum granulator equipment is relatively high, and the maintenance cost in the later stage is also relatively high.

In summary, both disc granulators and drum granulators have their own advantages and disadvantages. When choosing, enterprises should comprehensively consider factors such as the characteristics of their raw materials, production scale, financial situation, and requirements for particle quality, in order to select the most suitable granulation equipment for themselves.

How does the roller extrusion granulator produce high-strength organic fertilizer granules

fertilizer granulator May 14, 2025

In the process of organic fertilizer granulation, the roller extrusion granulator relies on strong pressure to shape organic fertilizer particles with high strength.

The pre treated mixed organic fertilizer material is continuously fed into the extrusion granulator. The pressure device inside the granulator begins to function, exerting tremendous pressure on the material. Under strong pressure, materials are forced to pass through mold holes of specific shapes. At the moment when the material is extruded from the mold, a columnar shape is formed. Subsequently, the cutting device will precisely cut the columnar material into particles of appropriate length according to the preset length.

The extrusion granulation method produces organic fertilizer particles with significant characteristics of high density and strength. This is because during the high-pressure extrusion process, the distance between material molecules is greatly compressed, and the internal structure of particles becomes tighter. High strength particles perform well during storage and transportation, able to withstand bumps and collisions, and are less prone to breakage and pulverization. This effectively ensures the quality and nutrient content of fertilizers, whether it is long-term storage or long-distance transportation, it can maintain the integrity of particles and provide users with stable and reliable products.

Another major advantage of the roller extrusion granulator is the precise control of particle shape and size. By changing different molds, operators can produce organic fertilizer particles of various shapes and specifications as they please, such as cylindrical, spherical, sheet-like, etc. This flexibility fully meets the diverse needs of different users and markets. For example, some special agricultural planting scenarios or horticultural cultivation may have specific requirements for the shape and size of fertilizer particles, which can be easily handled by extrusion granulators.

In addition, the roller extrusion granulator has high production efficiency and can work continuously and stably, producing a large amount of organic fertilizer particles per hour. It also has strong adaptability to raw materials, whether it is organic materials with high viscosity or raw materials with high fiber content, they can smoothly complete the granulation process in the extrusion granulator. The extrusion granulator provides a solid guarantee for the production of high-quality and diversified organic fertilizers with its unique granulation method.

fertilizer granulator May 14, 2025

The organic fertilizer flat mold granulator, with its flexible and diverse granulation characteristics, has demonstrated strong adaptability and creativity in the field of organic fertilizer production.

On the one hand, the flat die granulator is very flexible in adjusting the particle size. By replacing flat molds with different apertures or adjusting the cutting length of the blade, operators can easily produce organic fertilizer particles of various sizes. This flexibility enables enterprises to customize and produce fertilizer granules of the most suitable size according to the needs of different customers, the planting requirements of different crops, and different fertilization methods. For example, for some economic crops that require precise fertilization, smaller particle sizes can be produced to more accurately control the amount of fertilizer applied; For crops grown on a large scale, larger particles may be more convenient for mechanical fertilization operations.

On the other hand, the flat mold granulator has a wide adaptability to different formulations of organic fertilizer raw materials. Whether it is a formula based on animal manure as the main raw material, a formula with a large amount of fibrous substances such as crop straw and sawdust added, or a special formula containing multiple trace elements and biological agents, the flat mold granulator can smoothly pelletize. It can adapt to the differences in physical properties of different raw materials, such as viscosity, humidity, etc. By adjusting parameters such as roller pressure and material conveying speed reasonably, it ensures the stability and efficiency of the granulation process.

In addition, the flat mold granulator also has diversity in production modes. It can form large-scale automated production lines with other equipment to achieve continuous and efficient industrial production; It can also work independently to meet the small-scale production needs of small production enterprises or family farms. The flexibility of this production mode enables the flat mold granulator to play an important role in organic fertilizer production scenarios of different scales.

In terms of granulation shape, although the flat mold granulator mainly produces columnar particles, through some special mold design and modification, it can also produce particles that are approximately spherical or other special shapes, further meeting the personalized demand for fertilizer particle shape in the market.

The organic fertilizer flat mold granulator, with its flexibility and diversity in particle size, raw material formula, production mode, and granulation shape, has become a powerful assistant for organic fertilizer production enterprises, helping them quickly respond to customer needs in fierce market competition, produce diversified products, and expand market share.

The difference between flat die granulator and disc granulator in processing fertilizers

fertilizer granulator May 14, 2025

Both flat die granulators and disc granulators have their own advantages in the field of organic fertilizer granulation.

From the perspective of granulation method, the flat die granulator squeezes the material on the flat die through the pressure roller, causing the material to be extruded into shape through the die hole; The disc granulator allows materials to agglomerate into granules on a rotating disc through the action of multiple forces.

In terms of particle quality, the flat die granulator produces particles with regular shapes, consistent sizes, high strength, and good stability during storage and transportation. The particles produced by the disc granulator are round, but their strength is relatively weak.

In terms of raw material adaptability, the flat die granulator has certain requirements for the humidity and viscosity of the raw materials, but can handle a variety of organic materials. The disc granulator has strict requirements for the humidity of raw materials, and excessive or insufficient viscosity is not conducive to granulation.

In terms of production efficiency, the flat die granulator has a compact structure, a relatively stable production process, and a considerable output per unit time. The continuous production capacity of the disc granulator is strong, but it may take some time to adapt when adjusting parameters such as particle size.

In terms of energy consumption, the flat die granulator mainly consumes energy in the rotation of the pressure roller and material extrusion, with relatively high energy consumption. The energy consumption of the disc granulator is mainly due to the rotation of the disc, which is relatively low.

In terms of equipment maintenance, the flat mold and pressure roller of the flat mold granulator are key components, and the cost of replacement after wear is relatively high, making maintenance relatively complex. The disc granulator has a simple structure, easy maintenance, and low cost of component replacement.

In terms of investment cost, the price of flat die granulator equipment is relatively high, and the initial investment is large. The price of the disc granulator is relatively affordable and suitable for enterprises with limited funds.

Therefore, if we focus on particle strength and shape regularity, have certain screening ability for raw materials, and have sufficient funds, a flat die granulator is more suitable. If you pursue low energy consumption, low cost, and simple maintenance, and do not have strict requirements for particle strength, a disc granulator is a good choice.

Flat die granulator processes fertilizers in a stable manner through extrusion and molding

fertilizer granulator May 14, 2025

The flat mold granulator provides a reliable guarantee for the production of high-quality organic fertilizer granules through stable extrusion and molding during the organic fertilizer granulation process.

The core components of a flat mold granulator are the flat mold and the pressure roller. During operation, the material is evenly conveyed to the surface of the flat mold, and the pressure roller is tightly pressed onto the flat mold under power drive and rotates around the axis. Under the strong squeezing of the pressure roller, the material is extruded through the holes on the flat mold, forming columnar particles. Subsequently, the cutting blade cuts the columnar particles into appropriate lengths, completing the entire granulation process.

This granulation method produces organic fertilizer particles with regular shapes and uniform sizes. The regular shape facilitates the neat stacking of fertilizers during storage and transportation, reducing gaps and scattering caused by irregular particles. Uniform size ensures that each particle carries a relatively consistent amount of nutrients during fertilization, allowing crops to absorb nutrients more evenly and avoiding situations of excessive or insufficient local nutrients, thereby improving the efficiency of fertilizer use.

The stability of the flat mold granulator is extremely high. Its structural design is reasonable, and key components have been carefully selected and processed to withstand long-term, high-intensity workloads. The precision of the combination between the flat mold and the pressure roller is high. During operation, the pressure roller has a stable squeezing force on the material, and there will be no fluctuations in size, which ensures the stable quality of organic fertilizer particles produced in each batch. Whether it is a small organic fertilizer production workshop or a large industrial production enterprise, they can rely on flat die granulators to stably produce products that meet quality standards.

In addition, the flat mold granulator has strong adaptability to raw materials. It can process various organic materials with different properties, such as livestock manure, crop straw, distiller’s grains, etc. As long as these raw materials are properly pre treated and the parameters such as moisture and particle size are adjusted, they can be smoothly granulated in a flat mold granulator. The flat die granulator has become a reliable equipment in organic fertilizer production due to its stable extrusion and forming granulation methods.

How does the organic fertilizer flat mold granulator process organic fertilizers

fertilizer granulator May 14, 2025

The organic fertilizer flat mold granulator is like a skilled craftsman in the production process of organic fertilizer, carefully creating high-quality granules.

Firstly, the organic fertilizer particles produced by the flat mold granulator have high strength. During the granulation process, the material passes through the flat mold holes under the strong pressure of the pressure roller. This tight compression makes the internal structure of the particles dense and enhances the binding force between molecules. Therefore, the produced particles can withstand certain external impacts and friction, and are not easily broken or pulverized during storage and transportation. This not only ensures the integrity of the fertilizer when it reaches the user’s hands, but also prevents nutrient loss caused by particle breakage, ensuring that the fertilizer’s effectiveness is fully utilized.

Secondly, the flat mold granulator can effectively control the porosity of the particles. The appropriate porosity is crucial for organic fertilizers, as it relates to the rate of fertilizer dissolution and nutrient release efficiency in the soil. The flat die granulator forms a uniform pore structure inside the particles through precise extrusion and forming processes. This pore structure is conducive to the rapid infiltration of water, allowing fertilizers to dissolve quickly in the soil, while ensuring slow and sustained nutrient release, providing long-term stable nutrient supply for crops.

Furthermore, the surface of the particles produced by the flat mold granulator is smooth. The smooth surface of the particles not only makes the appearance of the fertilizer more attractive, but also reduces friction with the fertilization equipment during the fertilization process, allowing the fertilizer to pass through the fertilizing equipment more smoothly and improving the uniformity and accuracy of fertilization. At the same time, smooth particles on the surface are less likely to adsorb dust and impurities, maintaining the purity of the fertilizer.

In addition, the flat mold granulator can effectively retain beneficial components and microbial communities in organic fertilizers during the granulation process. Due to its relatively mild granulation process, unlike some high-temperature granulation methods that can damage the active ingredients in fertilizers. This enables the produced organic fertilizer to better utilize its effects of improving soil and promoting soil microbial activity, creating a favorable soil environment for crop growth.

The organic fertilizer flat mold granulator, with its unique granulation method, creates high-quality organic fertilizer particles from multiple aspects such as particle strength, porosity, surface smoothness, and protection of beneficial components, meeting the strict requirements of modern agriculture for high-quality fertilizers.

Different characteristics of disc granulator and roller extrusion granulator during granulation

fertilizer granulator May 14, 2025

In the field of organic fertilizer production, disc granulators and roller extrusion granulators are commonly used equipment, each with its own characteristics.

From the perspective of granulation principle, the disc granulator aggregates materials into granules through continuous rolling on a rotating disc, utilizing centrifugal force, friction force, and gravity, with a relatively gentle process; The roller extrusion granulator relies on strong pressure to forcefully extrude the material through the mold holes, resulting in a more robust granulation process.

In terms of particle quality, the particles produced by the disc granulator have a rounded shape, relatively uniform size, and are more evenly distributed in the soil, which is conducive to the absorption of nutrients by crops. However, its particle strength is average. The particles produced by the roller extrusion granulator have high density and strength, and are not easily crushed and powdered during storage and transportation, but their shape is mostly cylindrical and relatively single.

In terms of raw material adaptability, the disc granulator has strict requirements for raw material humidity and viscosity, as being too dry or too wet can affect the granulation effect. The roller extrusion granulator has stronger adaptability to raw materials, and can handle materials with high viscosity and fiber content well.

In terms of production efficiency, the disc granulator has a simple structure, easy operation, strong continuous production capacity, and is suitable for large-scale production. The production efficiency of the roller extrusion granulator is not low, but the equipment structure is complex and difficult to maintain, which will to some extent affect the continuity of production.

In terms of energy consumption, the disc granulator mainly relies on disc rotation, which has relatively low energy consumption; The roller extrusion granulator requires strong pressure and high energy consumption.

In terms of investment cost, the price of the disc granulator is relatively cheap, and the initial investment is small; The cost of roller extrusion granulator equipment is high, and the cost of mold replacement is also not low.

In summary, if pursuing a beautiful particle appearance, high production efficiency, and low investment cost, a disc granulator is a good choice, suitable for producing organic fertilizers with low requirements for particle strength. If the raw materials are complex and diverse, with high requirements for particle strength and shape control, the roller extrusion granulator can better meet the needs, despite its high energy consumption and cost.

Innovative granulation method of new organic fertilizer granulator leads industry transformation

fertilizer granulator May 14, 2025

In the field of organic fertilizer production, the new type of organic fertilizer granulator has emerged with its unique and innovative granulation method, bringing new opportunities for the development of the industry.

The new organic fertilizer granulator integrates multiple advanced technologies, and its granulation process is exquisite and efficient. Firstly, in the material pretreatment stage, it is equipped with an intelligent detection system that can quickly analyze key indicators such as humidity, viscosity, and particle size of the material, and automatically adjust the material ratio and pretreatment method based on these data to ensure the optimal state of the material entering the granulation process.

Entering the core granulation process, the new organic fertilizer granulator adopts composite force field granulation technology. By cleverly combining mechanical pressure, centrifugal force, and electromagnetic force, materials interact with each other in a complex and orderly force field environment. Mechanical pressure provides the basic compaction effect, causing the material to initially aggregate; Centrifugal force causes particles to continuously roll and break in during rotational motion, resulting in a smoother surface and a more regular shape; Electromagnetic force plays a “micro control” role, enhancing the attraction between charged particles in materials, accelerating the tight bonding of internal structures of particles, and improving particle strength.

During the granulation process, the new granulator also utilizes dynamic temperature control technology. The granulation area is equipped with high-precision temperature sensors to monitor temperature changes in real time. Because temperature has a significant impact on the viscosity and chemical reactions of materials, when the temperature is too high or too low, the system will automatically activate the temperature control device to accurately adjust the temperature through air or water cooling, ensuring that the granulation process is carried out in a suitable hot environment and avoiding unstable particle quality caused by temperature issues.

Moreover, the new organic fertilizer granulator is equipped with a flexible and versatile mold switching system. According to different market demands and product positioning, operators can quickly replace molds to produce various shapes (such as spherical, columnar, and sheet-like) and different sizes of organic fertilizer particles. This flexibility greatly expands the application scope of the product and meets diverse agricultural production needs.

The granulation method of the new organic fertilizer granulator not only improves production efficiency, but also significantly improves particle quality. The organic fertilizer produced has uniform particle size, high strength, smooth surface, and is not easily broken or clumped during storage and transportation. At the same time, this innovative granulation method can better retain nutrients and beneficial microorganisms in the materials, improve the fertilizer efficiency of organic fertilizers, and provide strong support for the green and sustainable development of modern agriculture.
