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

fertilizer granulator Oct 13, 2025

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:
 

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

Dynamic synergy between NPK fertilizer production lines and the agricultural production cycle

fertilizer granulator Oct 13, 2025

NPK fertilizer production isn’t a fixed process; it’s a dynamic system deeply integrated with the agricultural production cycle. Two to three months before spring plowing, NPK fertilizer production lines should prioritize production of high-nitrogen formulas (such as 25-10-10) to meet the nutritional needs of seedling crops like wheat and corn. During this period, granulation production should be adjusted to increase daily production capacity by 30%, while also stockpiling raw materials to avoid supply interruptions during the peak spring plowing season.

During the summer fruit and vegetable bulking season, NPK fertilizer production lines must quickly switch to high-potassium formulas (such as 15-10-25). A modular silo design allows for formula conversion within four hours, and a low-temperature granulation process (controlled at 55-60°C) is used to minimize potassium loss.

After the autumn harvest, to meet soil maintenance needs during the fallow period, NPK fertilizer production lines will increase the proportion of slow-release NPK products containing humic acid. This requires extending the coating process and adjusting the nutrient release cycle from 30 days to 90 days.

This dynamic synergy requires the establishment of a “farming cycle-production plan” linkage mechanism. By analyzing historical planting data to predict demand, this ensures that fertilizer supply is precisely matched to crop nutrient absorption points, avoiding production capacity waste and ensuring agricultural production efficiency.

Technical adaptation strategies for organic fertilizer production lines in low-temperature environments

fertilizer granulator Oct 11, 2025

The impact of low temperatures in northern winter on organic fertilizer fermentation efficiency has necessitated low-temperature adaptation of organic fertilizer production lines. Key measures focus on maintaining fermentation temperature and raw material pretreatment.

In terms of bacterial strain selection, production lines must utilize low-temperature-tolerant composite inoculants to ensure viability at temperatures between 5-15°C (with a viable bacterial count retention rate exceeding 85%), shortening fermentation start-up time to within 24 hours.

In terms of workshop design, insulation and a photovoltaic-assisted heating system are required to maintain the fermentation room temperature above 10°C through solar heating. Some organic fertilizer production lines also utilize closed fermentation chambers, utilizing bioheat generated during the fermentation process to maintain a constant internal temperature (temperature fluctuations within ±3°C).

In raw material pretreatment, to address the difficulty of raw materials such as straw degrading at low temperatures, production lines incorporate a pre-crushing step (crushing the raw materials to 0.5-1 cm) and use hot water humidity control (controlled at 30-40°C) to raise the initial raw material temperature and ensure fermentation efficiency.

These adaptation measures have increased the capacity utilization rate of organic fertilizer production lines in northern winter from the original 50% to over 80%, and the organic matter content of finished fertilizers has stabilized at over 55%, effectively ensuring the supply of fertilizers for agricultural production in northern winter.

How can organic fertilizer production lines adapt to the needs of ecological agriculture?

fertilizer granulator Oct 11, 2025

Ecological agriculture’s requirements for “no chemical additives” and “full-cycle composting” of fertilizers are driving targeted adjustments to organic fertilizer production lines.

In ecological farming, the use of chemical regulators is prohibited. Organic fertilizer production lines must optimize the microbial community structure to achieve natural composting of raw materials. For example, complex microbial agents can be used instead of traditional chemical ripening agents to ensure that no exogenous pollutants are introduced during the fermentation process.

At the same time, ecological agriculture emphasizes the “cultivation-livestock cycle.” Organic fertilizer production lines must adapt to a variety of ecological raw materials, such as rice husks and mushroom residues, using precise pulverization and mixing processes to ensure balanced nutrient release.

Furthermore, to meet the demand for “light and simplified fertilization” in ecological farming, end-of-line production lines must enhance granulation and slow-release technologies to adapt fertilizers to various ecological farming scenarios, such as drip irrigation and broadcasting, thus achieving a closed loop of “fertilization-growth-soil maintenance.”

At present, the application rate of products of this type of organic fertilizer production line adapted to ecological agriculture in ecological fruit and vegetable planting has increased by 35% compared with ordinary production lines. After some ecological tea gardens adopted this type of fertilizer, the tea polyphenol content in tea increased by an average of 8%, and the pass rate of pesticide residue detection remained at 100%, further verifying the adaptability of the production line to ecological planting.

How to prevent blockages in new type organic fertilizer granulators?

fertilizer granulator Oct 10, 2025

Many people occasionally encounter blockages when using new type organic fertilizer granulators (raw material gets stuck in the granulation chamber, preventing pellets from coming out). However, if you take three steps in advance, this problem is virtually eliminated.

First, avoid any hard lumps in the raw material. Whether it’s manure or straw, lumps may form after fermentation. Before feeding, be sure to use a crusher to break up any lumps. Keep lumps no larger than 1 cm, otherwise they will get stuck in the die holes of the new organic fertilizer granulator. Accumulating these lumps will cause a blockage.

Second, control the moisture content of the raw material. Although new type organic fertilizer granulators are moisture-resistant, raw material that is too moist (over 65%) will stick to the granulation chamber, while too dry (less than 45%) will produce fine powder and clog the screen. Before each feeding, grab a handful of raw material and form a ball that breaks apart easily. This will ensure the raw material flows smoothly through the granulation chamber without blockage.

Third, perform a component inspection every day before starting the machine. Check the pressure roller of the new type organic fertilizer granulator to see if it’s stuck and the scraper at the discharge port to see if it’s blunt. If the roller can’t turn or the scraper is blunt, the pellets won’t come out and the machine will jam. Simply turn the roller manually and check the scraper to see if it’s sharp. If there’s any problem, adjust it immediately to avoid jams.

Organic fertilizer production line was used to process chicken manure

fertilizer granulator Oct 10, 2025

Organic fertilizer is favored by agricultural production because of its ability to improve soil structure, increase organic matter content and enhance soil fertility. Among them, chicken manure as a high-quality organic fertilizer raw material, its processing has attracted much attention. This article will explore how to efficiently process organic manure from chicken manure through organic fertilizer production lines and ensure its quality and safety.
 

1. Raw material preparation and pretreatment

 
Chicken manure requires strict pretreatment before processing to eliminate pathogens and weed seeds in it. This usually involves composting treatment, which breaks down organic matter through the action of microorganisms while releasing heat to achieve bactericidal and deodorizing effects. The pre-treated chicken manure can enter the organic fertilizer production line for further processing.
 

2. Drying and sterilization of chicken manure

 
One of the key steps in an organic fertilizer production line is drying. By using professional drying equipment, such as Rotary Dryer Machine, the moisture content of chicken manure can be effectively reduced, its stability can be increased, and the subsequent granulation process can be facilitated. In addition, the high temperature during the drying process can further sterilize, ensuring the safe use of organic fertilizers.

3. Ingredient mix and nutrition balance

 
In the organic fertilizer production line, chicken manure is usually mixed with other auxiliary materials such as straw, shells, etc., to adjust the carbon nitrogen ratio and ensure the nutrient balance of organic fertilizer. This step is done through the Bulk Blending Fertilizer Production Line, ensuring that the final product can meet the needs of the different crops.

4. Granulation molding

 
The mixed raw materials will enter the granulator, such as the Fertilizer Granules Compaction Machine, for molding processing. This step forms the raw material into a uniform granular form that is easy to apply and store. Granulation can not only improve the appearance of organic fertilizer, but also improve its dispersion and absorption rate in the soil.

5. Screening and packaging

 
The organic fertilizer after granulation needs to be screened by Rotary Screening Machine to ensure uniform particle size and meet product quality standards. The qualified product is then packaged to become the final chicken manure organic fertilizer product.

6. Quality control

 
In the whole process of organic fertilizer production line, quality control is an indispensable link. By regularly testing the number and activity of microorganisms in organic fertilizers, the effectiveness and safety of the product can be assessed. For example, the application of bio-organic fertilizer can increase the capacity of soil microorganisms to utilize carbon sources, improve microbial nutrient conditions, maintain high microbial activity, and increase soil microbial diversity.
 
Through the above steps, the organic fertilizer production line can efficiently convert chicken manure into high-quality organic fertilizer products. This processing method not only improves the efficiency of resource utilization, but also helps to improve the quality and safety of agricultural products, and also contributes to the sustainable development of agriculture. With the advancement of technology and the growth of market demand, organic fertilizer production lines will continue to play an important role in modern agricultural production.

How do new type organic fertilizer granulators adapt to different organic fertilizer raw materials?

fertilizer granulator Oct 10, 2025

New type organic fertilizer granulators are more flexible than traditional models. Whether it’s straw, manure, mushroom residue, or distiller’s grains, they can be adapted with minimal adjustments without having to replace equipment.

If using fermented straw for granulation, this raw material is fibrous and somewhat loose, making it difficult to produce compact pellets. Add 5%-8% bentonite (a common binder) to the raw material, mix it thoroughly before feeding it into the new type organic fertilizer granulator, and increase the roller pressure. This will ensure compact pellets without breaking them up and damaging the organic matter in the straw.

For wet, sticky raw materials like chicken manure and pig manure, the biggest concern is clogging the granulator. Instead of adding too much binder, add about 10% dry mushroom residue to reduce moisture. Also, slow the new type organic fertilizer granulator’s feed rate to allow the raw material to fully form in the granulation chamber. The resulting pellets are smooth and less likely to stick to the machine.
When it comes to fine raw materials such as mushroom residue and wine lees, they have moderate viscosity and do not require additional adhesives, which saves materials and time.

Even in small spaces! Flexible placement tips for windrow compost turning machines

fertilizer granulator Oct 9, 2025

Many small organic fertilizer plants worry about “small space and compost turning machine maneuvers.” In fact, as long as you master placement and routing techniques, a windrow compost turning machine can operate smoothly even in a space as small as 100 square meters.

First, the pile must be placed smoothly. Avoid stacking the pile in small, scattered, round piles. Instead, create long, narrow piles—for example, a 1-meter-wide, 1.2-meter-high, and 5-meter-long strip. This allows the compost turner to move along the strip in a straight line, eliminating the need for frequent turns. This saves space and ensures thorough turning. Leave a 1.5-meter-wide aisle between two long piles—just enough for the compost turner to move back and forth without hitting the adjacent piles.

Second, turning techniques are crucial. If the space is truly limited and the windrow compost turning machine needs to turn, don’t do it directly on the pile; instead, move it into the aisle. First, raise the compost turner’s blades and move it to the center of the aisle. Then, slowly turn (keeping the turning radius at least 2 meters) to avoid the tracks pressing into the pile and causing the material to clump.

Also, you can turn the compost in layers. If the pile is high (over 1.5 meters) and the site is not wide enough, the windrow compost turning machine can turn the material on the top layer first, loosening it, and then lower the blades to turn the lower layers. This allows for thorough turning without breaking up the pile.
