fertilizer granulator Aug 16, 2025

In the field of fertilizer production, it is very important to choose the right granulator, which directly affects product quality, production efficiency and corporate benefits. Faced with a wide range of fertilizer granulators, how to choose?

Raw material characteristics are the primary consideration. For processing high-humidity materials such as livestock and poultry manure, the rotary drum granulator can meet the needs; fiber raw materials such as straw have high hardness, and the high-pressure molding technology of the double roller press granulator can ensure the compactness of the particles.

The scale of production needs to be considered. Large production lines have a large daily output demand, and the rotary drum granulator has become the first choice due to its continuous operation ability. It can be adapted to 10,000-ton organic fertilizer projects to meet high-intensity production. Medium-sized enterprises can choose a disc granulator, which can balance efficiency and cost and is suitable for the production of 10-20 tons of compound fertilizer per day. For small workshops or laboratories, the flat die granulator is flexible to operate, occupies a small area, and can easily cope with small batch production.

The requirements for particle quality also affect the choice of granulators. If spherical particles with a high ball formation rate are required, the disc granulator is an ideal choice. The organic fertilizer particles it produces are round and have good commercial properties. For high-strength columnar particles, the double roller press granulator has a good molding effect, high particle hardness, and is not easy to break. The ring die granulator can flexibly switch molds and produce particles of different shapes and sizes to meet diverse needs.

From the perspective of process and economy, in the dry production process, the double roller press granulator does not need to add water, reduces the drying process, and reduces energy consumption. In wet production, the rotary drum granulator and the drying equipment work well together, which is suitable for large-scale continuous production. From the perspective of maintenance cost, the flat die granulator has fewer wearing parts and is easy to repair; although the hydraulic roller granulator has a higher initial investment, it is durable and has a lower long-term use cost.

Considering the above factors comprehensively, select the appropriate one from many models to make fertilizer production more efficient and higher quality.. 

Disc Granulator: The Core Powerhouse of Fertilizer Production

fertilizer granulator Aug 12, 2025

In modern fertilizer production lines, the disc granulator acts like a skilled “magician,” transforming various raw materials into perfectly uniform granules. As the core equipment for producing organic fertilizer, organic-inorganic compound fertilizer, chemical fertilizer, and biofertilizer, it is revolutionizing the entire fertilizer manufacturing industry.

When organic fertilizer processed by disc granulator is applied to soil, the organic matter content increases significantly, followed by an increase in soil organic nitrogen. This virtuous cycle not only improves soil structure but also creates an ideal environment for crop growth. The three major advantages of disc granulation—uniform particles, easy moisture control, and high granule strength—make it the preferred choice for fertilizer manufacturers.

The Ingenious Combination of Disc Granulation Line

A complete disc granulation production line is a perfect example of multiple precision equipment working in harmony. Each machine plays an indispensable role in ensuring the excellent quality of the final product:

1. Disc Granulator – The heart of the production line, responsible for transforming mixed materials into uniform granules

2. Horizontal Mixer – Ensures thorough and uniform mixing of various raw materials

3. Drum Screening Machine – Precise grading to ensure consistent particle size

4. Coating Machine – Provides a “protective coat” for granules to prevent caking

5. Multiple Silos Single Weigh Static Automatic Batching System – Accurately controls formula ratios

6. Automatic Packing Machine – Efficiently completes product packaging

Why Choose Disc Granulation Technology?

Compared with traditional granulation methods, disc granulation technology offers incomparable advantages. Its unique tilted rotating design creates ideal rolling motion of materials in the disc, resulting in uniform granulation. Operators can easily control particle size and moisture content by adjusting parameters such as disc inclination angle, rotation speed, and water spray volume to meet different customer requirements.

Even more exciting is the disc granulator’s strong adaptability to raw materials—whether powdered organic matter or chemical materials, it can handle them perfectly. This flexibility allows manufacturers to quickly switch between different product formulations to seize market opportunities.

Investing in a disc granulation production line is not just about purchasing equipment; it’s about injecting strong momentum into your company’s future development. In today’s world of increasingly stringent environmental requirements and booming organic agriculture, this efficient and flexible production system will become your secret weapon to conquer the market!

What precautions should be taken during organic fertilizer production?

fertilizer granulator Aug 6, 2025

The efficient operation and high-quality output of an organic fertilizer production line depend on precise control of production details. Attention to precautions in every step not only ensures product quality, but also improves production safety and stability, empowering green agriculture.

The fermentation process is a key quality control point. Precise control of the fermentation temperature is required. Real-time monitoring by the equipment ensures that the core temperature of the material remains within the appropriate range, which not only kills pathogens and insect eggs but also promotes microbial activity. Regularly turning the material ensures uniform oxygen supply and prevents localized anaerobic conditions that can cause odor and nutrient loss. The fermentation cycle must be strictly adhered to. If it is too short, composting will be incomplete, while if it is too long, nutrient loss can occur. Flexible adjustments are required based on the raw material ratio.

Equipment operation and maintenance are essential. Before starting equipment like crushers and granulators, check component integrity and bearing lubrication to avoid running them unloaded or overloaded. During operation, closely monitor abnormal signals such as current and noise. If any problems are detected, stop the machine immediately for investigation. Regularly clean residual material from the equipment to prevent caking and mold that could affect the next production run, extending the equipment’s service life.

Environmental protection and safety measures must be implemented. The production area is equipped with dust collection and exhaust gas treatment equipment to reduce dust dispersion and odor emissions. Operators must wear protective equipment and strictly adhere to operating procedures to avoid direct contact with fermentation materials or moving equipment parts. Fermentation wastewater must be treated before discharge to prevent environmental pollution and comply with environmental protection policies.

Product storage and testing must be standardized. Finished organic fertilizer should be stored in a well-ventilated and dry warehouse to prevent moisture and caking. Each batch of product is sampled and tested for nutrient content, heavy metal indicators, and other indicators to ensure compliance with national standards and enhance market acceptance.

Only by carefully controlling these precautions can the organic fertilizer production line consistently produce high-quality fertilizer, achieve a win-win situation for both environmental protection and profitability, and provide reliable support for sustainable agricultural development.

How to Preventing Caking from the NPK Fertilizer Production Process

fertilizer granulator Nov 27, 2019

NPK compound fertilizer is prone to cake because of its strength, moisture content, storage and so on. This article will introduce how to prevent caking from the process operation of NPK fertilizer production process.

NPK fertilizer production equipment produce products with smooth and uniform particles

Non-uniform particles, too many fine particles, non-smooth fertilizer, the compressive resistance, wear resistance is also poor, easy to be compressed and deformed in storage and transportation. The contact area between particles increase, which is easy to agglomerate. In order to produce products with uniform and smooth particle size, appropriate fertilizer granulator machine should be selected. Disc granulator and rotary drum granulator can produce moderate size particles and meet the requirements. If there is a higher requirement for the shape of the particles, it can also be combined with the ball shaping machine to polish the particles to ensure that the shape is qualified.

Strengthening the control of screening machine

In order to ensure the consistency of particle size and reduce the caking of powder, the product needs to be screened. According to the particle size of the product, different screens can be selected, and secondary screening can be selected in the process. Pay attention to the material screening in production, timely clean the screen.

Dryer reduces product water content

NPK compound fertilizer has a high water content, which will lead to salt reaction and cause hardening. The higher the water content, the easier the particles to agglomerate. Therefore, the NPK compound fertilizer production line must use a dryer to reduce the moisture content to the allowable range.

After the particle is dried by the dryer, the temperature is higher and the hygroscopicity effect will appear, so it needs to be cooled. The cooler reduces the material temperature to room temperature, and the product can be saved.

Coating treatment is used in NPK fertilizer production process

Choose the suitable material and use the coating machine to coat the particles. At the same time, pay attention to the amount of wrapping agent added. The amount of wrapping agent added is small, the particles are not wrapped completely, the effect is poor; the amount of adding is large, the wrapping oil will infiltrate into the inside of the NPK fertilizer, and the product is easy to cake.

Bio-organic fertilizer production line

fertilizer granulator Nov 25, 2019

The development of the industrial age has made great contributions to agriculture in fertilizers, especially organic fertilizers, which are produced. Now the production of bio-organic fertilizers has been mechanized, scaled and integrated, and can provide perfect fertilizer production system, let’s go into the process of biofertilizer project.

The production of bio-organic fertilizer should be determined according to the functional special effects of organic fertilizer. Then the workers first pulverize various raw materials into a certain fineness of organic materials, and mix them according to the formula in the mixer. In this process, a key step is a proportional addition of a kind of “bio-fermenting agent”, which is mixed into the fermentation tank. Because of the deep-cell aerobic fermentation, the floor space is small, the fermentation process does not require labor, and the fermentation cost is greatly saved. Because of the mechanized production, so the fermentation is uniform, no dead angle, and the product quality of the organic fertilizer is ensured from the process. After one night, the temperature of the input raw materials rose quickly, reaching a maximum of 70 degrees.

At this time, the staff could use the compost turning machine and turn on the air blowing equipment. After the end of the dumping, the end of the pool was fermented. The finished product, the new raw materials can enter the fermentation tank, and then repeat.

After the fermentation of the raw material is finished, the following operations can be carried out, including pulverizing the large-sized fertilizer therein, and then uniformly stirring, and then granulating the fertilizer granules by using a fertilizer granulator machine, followed by drying, cooling, sieving and packaging. The final product is put into storage and can be sold at any time.

Understanding the production process of bio-organic fertilizers has a very important role for farmers to purchase fertilizers in the future. Our company produces all kinds of organic fertilizer equipment, and can also help design organic fertilizer production lines. Welcome friends from all walks of life to visit our factory for cooperation.

We provide fertilizer manufacturing process including fertilizer granulator machine, pulverizer, rotary dryers, coolers, drum screening machines, coating machines, packing machines and other equipment. The whole set of fertilizer production equipment can complete the processing and coating of the particles of the complex fertilizer, so that the fertilizer has high utilization rate in the soil.

Benefits of NPK Fertilizer Production Process

In the process of fertilizer production, the structure and composition of cladding layer can be adjusted to control the release rate of nutrients so as to reduce leaching loss and improve the utilization rate of fertilizers. This fertilizer product not only has the characteristics of slowly releasing nutrients, but also can meet the needs of nutrients for the whole growth period of crops and the ratio of nutrient utilization rate by one basal application. Conventional quick-acting fertilizer increased by 10-30 percentage points, the utilization rate of nitrogen fertilizer could reach 50%-70%, and the amount of fertilizer used could be reduced by 10%-40%. Due to the remarkable economic and social benefits of slow-acting and high-utilization wrapped complex fertilizer, and in line with the direction of fertilizer development, it is worth vigorously promoting.

The working principle of the disc granulator in the fertilizer production line

fertilizer granulator Nov 19, 2019

The disc granulator machine is mainly used in the NPK fertilizer production line and organic fertilizer production line to produce various granular products; it’s also used in pharmaceutical products, fertilizers, feeds, etc. Adopting the overall arc structure, the granulation rate can reach above 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

Disc fertilizer granulator machine working principle:
The raw meal powder is uniformly wetted by the atomized water in the mixer to form a spherical core having a uniform particle size, and then fed into a ball plate for ball formation. The moisture of the ball should be controlled at 12-14%. Most of the water should be added in the twin-shaft mixer. Only a small amount of supplementary water is added to the ball plate, and the amount of water added is controlled to be about 0 to 3%. The dry powder granulation is directly added to the ball-forming plate, and the proper amount of water is sprayed. The raw material nucleus enters the spherical disk and is subjected to centrifugal force, friction and gravity in the disk, and moves along the parabola. Due to the cohesiveness and plasticity of the material, the cores are bonded to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed and the moisture are constant, the balls of different particle sizes roll downward from the edge of the disc at different disengagement angles due to different gravity. During the continuous rolling process, the ball continuously discharges the water in the ball out of the surface. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the ball has certain strength, and then the disk is rotated with the tilting of the disk. The sides are discharged out of the pan.

Disc granulator performance advantages:
1. The raw materials are suitable for a wide range of applications. They can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, and magnetic fertilizer etc.) of compound fertilizer.
2. The disc granulator is light in weight, low in height, and flexible in process;
3. The machine has simple structure, convenient adjustment and superior performance.
4. The use of unique unpowered combination scraper integration reduces auxiliary power consumption.

5, high ball formation rate, large rounded particle strength, intuitive operation, easy maintenance and so on.
