The produced fertilizer pellets are even in size and have a neat appearance, making them easy to package, store, and apply mechanically. This significantly enhances the commercial value and market competitiveness of organic fertilizers.

3.Energy Efficiency and Environmental Protection for Sustainable Agriculture

The new type organic fertilizer granulator is designed with low energy consumption and low emissions in mind, reducing operational costs by over 20% compared to traditional equipment. The entire production process requires no chemical binders, making it truly green and pollution-free.

Organic waste is no longer a burden—it’s a resource in the wrong place. With its efficiency, eco-friendliness, and cost-effectiveness, the new type organic fertilizer granulator serves as a critical link between waste management and eco-friendly agriculture.

Flat die granulator: Understanding the “Simple and Efficient” logic of granulation

Written by fertilizer production line on October 16th, 2025. Leave a comment

In fertilizer granulation production, flat die granulators are the preferred equipment for small and medium-sized enterprises due to their simple structure and easy operation. They are particularly suitable for fertilizers with complex raw material characteristics, such as organic fertilizers and biofertilizers. The core of their granulation principle lies in the vertical extrusion design of a “flat die + roller” system, which ensures effective granulation while reducing operational complexity.

The core components of a flat die granulator are a horizontally positioned circular die (flat die) and one or two rollers above it. Cylindrical holes are evenly distributed across the die surface. Raw material falls from the feed inlet between the die and rollers. A motor drives the rollers to rotate, and friction forces the rollers continuously press the raw material against the die surface, forcing it into the holes.

In the die holes, the raw material undergoes a process of “extrusion shaping → solidification forming.” A scraper below the die cuts the cylindrical material that emerges from the holes, forming pellets of uniform length.

Compared to other granulation equipment, the flat die granulator’s advantage lies in its adaptability to fibrous raw materials (such as fermented straw). The vertical compression of the rollers prevents fiber entanglement and facilitates die hole cleaning, making it suitable for the production of small and medium-sized batches of a wide variety of fertilizers.

With increasingly stringent environmental protection policies, fertilizer companies must not only maintain production capacity but also meet the green requirements of “low dust, low noise, and low energy consumption.” As the core equipment in the production line, the ring die granulator’s operation directly impacts environmental performance.

First, dust source control. The ring die granulator’s fully sealed feed and discharge structure reduces dust spillage. The feed inlet utilizes a “soft-connected sealing sleeve” to prevent raw material leakage during conveying; the discharge outlet connects to a “sealed cooler,” ensuring pellet cooling within a sealed space.

Second, effective noise reduction is required. Mechanical friction and raw material impact during operation of the ring die granulator can easily generate noise, impacting the workshop environment. During routine maintenance, regularly checking the lubrication of the roller bearings and tightening the bolts connecting the ring die to the frame can reduce operating noise to below 75 decibels.

Third, optimizing energy consumption is essential. Green operation of the ring die granulator can be achieved through variable frequency speed regulation. Adjust the ring die speed according to the raw material characteristics and production needs to avoid the motor idling at full load; at the same time, regularly clean the residual raw materials in the ring die hole to ensure that the equipment always operates in the “high efficiency and low consumption” range.

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

NPK Fertilizer is an indispensable fertilizer in modern agricultural production. It contains three elements, nitrogen (N), phosphorus (P) and potassium (K), which are key nutrients for crop growth. To improve the nutritional value of NPK Fertilizer Production Line, it is necessary to optimize the selection of raw materials, production process control and technological innovation.

First of all, the choice of raw materials is the basis for improving the nutritional value of fertilizers. High-quality nitrogen fertilizer such as Urea, Ammonium Sulfate, Ammonium Chloride, Phosphate fertilizers such as Ammonium Dihydrogen Phosphate, Ammonium Phosphate Dibasic, Ground Phosphate Rock, Potassium Chloride, Potassium Sulphate and so on are the key raw materials for the production of high nutritional value compound fertilizer.

Secondly, the control of the production process is equally important. At the NPK Fertilizer Production Line, the balance of nutrients in the fertilizer can be ensured through the precise ratio of raw materials and mixing uniformity. The use of a Horizontal Ribbon Mixer or a Double Shafts Paddles Mixer for raw material mixing increases the efficiency and uniformity of mixing, thereby increasing the nutritional value of the fertilizer.

Technological innovation is also an important means to enhance the nutritional value of fertilizers. For example, the use of advanced fertilizer Granulator series such as Rotary Drum Granulator and Flat-Die Pellet Machine can improve the shape and size of fertilizer pellets, improve the solubility of fertilizer and increase the absorption rate of crops.

In addition, the screening process in the fertilizer production line cannot be ignored. Using a Rotary Screening Machine to screen fertilizer particles can remove unqualified particles and ensure the uniformity and quality of the fertilizer.

Finally, the drying and cooling process of the fertilizer also affects its nutritional value. The use of Rotary Dryer Machine and Rotary Cooler Machine can effectively control the moisture content of fertilizer, prevent nutrient loss or caking caused by excessive moisture, and ensure the quality and nutritional value of fertilizer.

In summary, through careful selection of raw materials, optimization of the Production process, the use of advanced granulation and screening technology, as well as control of drying and cooling links, the nutritional value of NPK Fertilizer Production Line can be effectively improved, so as to better meet the needs of modern agricultural production.

Ring die granulator: What is the core mechanism of pellet formation?

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

In fertilizer granulation production, the ring die granulator is a key piece of equipment for achieving “powdered raw materials → uniform granules.” It is particularly suitable for a variety of fertilizer types, including organic fertilizers, compound fertilizers, and biofertilizers. The key to its granule formation lies in the synergistic effect of the “ring die + press roller” system, as well as precise adaptation to the raw material characteristics.

The core working components of the ring die granulator are a ring die with densely packed holes (ring die) and two to three press rollers within it. When the machine is started, pre-treated (mixed and conditioned) fertilizer raw materials (usually with a moisture content of 15%-25%) are fed into the extrusion chamber between the ring die and the press rollers. The motor drives the ring die at high speed, while the press rollers follow in the opposite direction. Friction forces press the raw materials tightly against the inner wall of the ring die.

As the ring die continues to rotate, the raw materials are forcibly squeezed into the small holes of the ring die, where they undergo a process of “extrusion → shaping → solidification.” The shape of the small holes (circular, cylindrical, or oblate) determines the appearance of the pellets, while the length-to-diameter ratio of the holes (also known as the “compression ratio”) influences pellet hardness.

Finally, the formed pellets are cut by a scraper on the outside of the ring die, forming uniform fertilizer granules. The entire process achieves “continuous feeding and continuous granulation,” adapting to the mass production needs of organic fertilizer production lines.

How can a horizontal crusher “flexibly adjust” to address fluctuations in fertilizer raw materials?

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

Raw material fluctuations are common in fertilizer production. For example, the raw material for organic fertilizer may switch from “dry straw” to “wet bacterial residue,” or the raw material for compound fertilizer may change from “phosphate rock powder” to “potassium sulfate granules.” These fluctuations in raw material hardness, moisture content, and viscosity can lead to decreased pulverization efficiency and substandard particle size if the horizontal crusher cannot flexibly adjust.

Speed Adjustment to Adapt to Hardness Changes

When switching from “soft fibrous materials” (such as dry straw, which has low hardness) to “hard mineral materials” (such as phosphate rock, which has high hardness), the variable frequency motor can adjust the impeller speed to avoid excessive pulverization and dust generation. For hard materials, high speeds enhance impact and shear forces, ensuring effective pulverization. This allows adaptation to different hardness levels without changing equipment.

Gap Adjustment to Address Viscosity Differences

When processing high-viscosity raw materials (such as wet mushroom residue with a moisture content of 28%), a small gap between the impeller and the chamber wall can easily cause the material to stick to the wall. When processing low-viscosity raw materials (such as dry cake), a large gap will reduce grinding efficiency. A horizontal crusher can adapt to different viscosities, reducing sticking and ineffective grinding.

Screen Replacement to Adapt to Particle Size Requirements

Different fertilizer products require different particle sizes (organic-inorganic compound fertilizers require 3-5mm, powdered fertilizers require 0.8-1.2mm), and fluctuations in raw material quality may make the original screen size unsuitable. A horizontal crusher can quickly change screens with different apertures (commonly 0.5-10mm), flexibly meeting the particle size requirements of different raw materials and products.

How to choose the right raw materials to optimize the production effect of organic fertilizer products ?

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

Organic fertilizer is an important fertilizer source in modern agricultural production, and its production effect is directly related to soil fertility and crop yield. Selecting the right raw materials and optimizing the production process is the key to improving the quality of organic fertilizer.

First of all, the raw material selection of organic fertilizer should be based on the organic matter content, nutrient composition and microbial activity of the raw material. Common high-quality raw materials include animal manure, municipal sludge, domestic waste, sugar filter mud, wine lees, bean residue, straw, etc. After proper treatment and fermentation, these raw materials can be converted into nutrient-rich organic fertilizers.

In an organic Fertilizer Production Line, the Fertilizer Granulating Production Line is a key link in the formation of granular fertilizer. The granulation process not only improves the physical properties of fertilizer, but also helps to improve the application efficiency of fertilizer. For example, Fertilizer Granules Compaction Machine and Flat-Die Pellet Machine are commonly used granulation machines, which make raw materials into particles by extrusion, and these particles have good forming effect and high strength.

In order to further improve the quality of organic fertilizer, Windrow Compost Turning Machine plays an important role in the fermentation process. This equipment improves the fermentation efficiency by turning the compost, improving the ventilation conditions and promoting the rapid decomposition of organic materials.

In the production of organic fertilizers, the use of fertilizer shredders (such as Cage Crusher) is also essential. The pulverizer crushes the bulk organic material into the right size to facilitate subsequent mixing and granulation processes.

Finally, in order to ensure the uniformity of organic fertilizers and improve production efficiency, fertilizer mixers (such as the Horizontal Ribbon Mixer) and fertilizer Screening machines (such as the Rotary Screening Machine) are also indispensable equipment on the production line. Mixers are used for uniform mixing of raw materials, while sifters are used to separate fertilizer particles of different sizes to ensure consistency and quality of the final product.
Through scientific and reasonable raw material selection and production process optimization, it can not only improve the quality of organic fertilizer, but also contribute to the sustainable development of agriculture.

Horizontal crusher: How to ensure continuous operation of organic fertilizer production lines?

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

In fertilizer production, production line interruptions are one of the most troublesome issues for companies. Frequent downtime of the pulverizing equipment causes delays in upstream and downstream processes (such as raw material pretreatment and subsequent granulation), directly reducing daily production capacity. However, the horizontal crusher, with its targeted design, serves as a “stabilizer” for ensuring continuous production line operation. Its core advantages are concentrated in three aspects.

1. Anti-clogging Design Reduces Downtime for Cleaning

To address the problem of caking and clogging of fertilizer raw materials (especially high-humidity fermented materials and fibrous materials), high-quality horizontal crushers feature a “tilted discharge chamber + self-cleaning impeller” structure. The tilted chamber accelerates material discharge and prevents accumulation. Elastic scrapers at the end of the impellers scrape residual material off the chamber walls as they rotate, eliminating the need for frequent downtime for cleaning.

2. Feeding and Production Line Compatibility

It can be used with automatic feeding devices (such as belt conveyors and screw feeders). Frequency conversion controls the feed speed to match the raw material conveying and pelletizing process, preventing “overfeeding and machine blockage” or “overfeeding and idling.”

3. Durability Reduces Failure Frequency

To address the abrasive nature of fertilizer raw materials (such as minerals), the chamber wall is constructed of a wear-resistant alloy, extending its average service life by two times that of ordinary materials. The device also features an overload protection device. If the chamber is overloaded, the motor automatically shuts off, preventing extended downtime due to component damage. This design ensures “less downtime, more operation” for the organic fertilizer production line.

Chain crusher: Suitable for processing a variety of fertilizer raw materials

Written by fertilizer production line on October 13th, 2025. Leave a comment

In the fertilizer industry, raw materials used for different fertilizer types vary significantly. Organic fertilizers require the processing of straw and fermented livestock and poultry manure, while compound fertilizers often involve hard particles such as phosphate rock and potassium chloride. Chain crushers, with their versatile adaptability, can easily handle the crushing needs of these diverse raw materials.

For fibrous raw materials such as straw and rice husks, common in organic fertilizer production, the chain of a chain crusher uses high-speed impact to sever the fibers, eliminating the “fiber entanglement” problem common in traditional hammer mills. The resulting pulverized material is loose and easy to mix with other raw materials for fermentation. For cake-based raw materials (such as soybean meal and rapeseed meal), the chain’s shear force effectively breaks up lumps and produces uniform crushed particles, eliminating excess powder and reducing raw material waste.

Even for hard mineral raw materials used in compound fertilizer production, chain crushers with high-strength alloy chains can achieve crushing through continuous impact, and the equipment’s lining is made of wear-resistant material, extending its service life.

In addition, it has a higher tolerance for the moisture content of raw materials. Wet materials with a moisture content of about 20% can be directly crushed without additional drying, which greatly simplifies the organic fertilizer production process and reduces the company’s initial investment.

Organic fertilizer is an indispensable part of agricultural production, and every link of its production process is crucial. The correct use of organic fertilizer fermentation equipment can not only improve the quality and efficiency of fertilizers, but also ensure the safety and environmental protection of the production process. Here are a few key points to pay attention to when using organic fertilizer fermentation equipment:

Use of Uniform Feeder: In the production process of organic fertilizer, uniform feeding is an important link to ensure the quality of fermentation. By using a uniform feeder, the material can be ensured to enter the fermentation equipment continuously and evenly, avoiding the problem of incomplete or excessive fermentation caused by uneven feeding.

Selection and use of fertilizer mixer: mixer plays a role in the production of organic fertilizer. Horizontal Ribbon Mixer and Double Shafts Paddles Mixer are two common types of mixers that ensure an even mix of ingredients and improve fermentation efficiency. When using, pay attention to the mixing speed and time to avoid destroying the microbial activity in organic fertilizer.

Application of fertilizer Screening Machine: Organic fertilizer will produce materials of different particle sizes during fermentation. The Rotary Screening Machine or Vibration Screening Machine can effectively separate the fertilizer particles that meet the standard and improve the uniformity and quality of the final product.

Maintenance of Organic Fertilizer Production Line: Organic Fertilizer Production Line includes multiple links, such as raw material treatment, fermentation, drying, screening and packaging. Regular maintenance and inspection of all aspects of the equipment, such as Fertilizer Granules Compaction Machine, Flat-Die Pellet Machine, Rotary Drum Granulator, etc., can ensure the continuous and stable operation of the production line. Reduce the risk of failure.

Operation of Compost Turning Machine: compost turning machine, such as Windrow Compost Turning Machine, is the key equipment to improve the efficiency of compost fermentation. Proper operation can ensure the air permeability and temperature control inside the compost, promote the activity of microorganisms, and accelerate the decomposition of organic matter.

The rational use of fertilizer crusher: In the production process of organic fertilizer, the crushing of materials is an important step to improve the fermentation efficiency. Equipment such as Cage Crusher can crush large pieces of material into a suitable size for fermentation, but the crushing size should be adjusted to avoid excessive fine materials affecting the fermentation effect.

Environmental control: During the use of organic fertilizer fermentation equipment, the temperature, humidity and pH value of the fermentation environment need to be strictly controlled to ensure the activity of microorganisms and fermentation efficiency. At the same time, it is also necessary to pay attention to ventilation and stacking to avoid the accumulation of harmful gases.

Safe operation: When operating organic fertilizer fermentation equipment, the relevant safety procedures must be followed to ensure the safety of the operator. This includes properly wearing protective equipment, following instructions in the operating manual, and conducting regular safety training.

Through the strict implementation of these precautions, you can ensure the efficient, safe and environmentally friendly operation of organic fertilizer fermentation equipment, so as to produce high-quality organic fertilizer to meet the needs of modern agriculture.
