Features of the Bio-Organic Fertilizer Production Line

by organic fertilizer production line

Based on the core principle of “transforming waste into treasure,” the bio-organic fertilizer production line has established a unique production system that differentiates it from traditional chemical fertilizers and has become a key force in promoting the green transformation of agriculture. Its core advantage lies in transforming agricultural waste into functional fertilizers rich in active bacterial communities, achieving both ecological and economic benefits.

A notable feature is its diverse raw material system. The production line can process a variety of organic wastes, including livestock and poultry manure, crop straw, and food waste. Through pretreatment processes such as crushing and mixing, the carbon-nitrogen ratio of each material is adjusted to an optimal range for fermentation. For example, mixing chicken manure with corn straw in a specific ratio not only balances the composting rate of high-nitrogen raw materials, but also utilizes straw fiber to improve fertilizer permeability and enhance fermentation efficiency.

Intelligent control of the fermentation process is the core technology. It utilizes trough-type turning and constant-temperature fermentation technology. Sensors monitor the temperature, humidity, and oxygen content of the compost in real time. When the temperature is too high, the turning and turning system is activated to ensure that the thermophilic bacteria thrive within the optimal range. This precise control significantly shortens the material composting cycle and completely eliminates pathogens and weed seeds, achieving harmless treatment.

The functional complexity of the finished products of the biological organic fertilizer production line forms market competitiveness. After secondary aging and low-temperature drying, the finished product not only retains rich organic matter but also contains active functional bacteria such as phosphate- and potassium-solubilizing bacteria and Bacillus subtilis. Field trials have shown that continuous application of bio-organic fertilizer can increase soil organic matter content, reduce the use of chemical pesticides in greenhouse vegetable cultivation, and improve crop quality.

This “waste-resource-product” closed-loop model not only addresses agricultural non-point source pollution but also provides a natural solution for soil remediation. Driven by policies to reduce the use of chemical fertilizers and increase their efficiency, bio-organic fertilizer production lines are becoming a crucial link between ecological protection and food security, opening up new paths for sustainable agricultural development.

Where are flat die granulators used?

by organic fertilizer production line

With its unique extrusion molding principle, flat die granulators have demonstrated strong application potential in a variety of fields, making them an ideal choice for small- and medium-scale production. Their core structure consists of a flat die and a pressure wheel. The rotation of the pressure wheel squeezes the material through the die holes, forming cylindrical pellets. This simple and direct operation gives them wide applicability.

Flat die granulators perform exceptionally well in fertilizer production lines. When processing bio-organic fertilizers, they can directly pelletize wet fermented materials without the need for additional drying pretreatment, preserving the activity of beneficial bacteria while streamlining the production process. For nitrogen, phosphorus, and potassium compound fertilizers, their powerful extrusion capabilities can compress mixed powders into high-strength pellets, effectively eliminating the clumping problem associated with traditional pelleting. They are particularly suitable for producing high-concentration specialty fertilizers.

Flat die granulators are also essential for the feed processing industry. For poultry and livestock feed, they can compress raw materials such as straw powder and soybean meal into pellets, reducing feed losses during transportation. High-temperature extrusion kills parasite eggs in the raw materials, enhancing feed safety. In aquatic feed production, pellet density can be controlled by adjusting die hole size to meet the feeding needs of fish in different water layers.

In the environmental protection field, flat die granulators are a valuable aid in solid waste treatment. They can compress municipal sludge, agricultural and forestry waste, and other materials into fuel pellets, realizing waste resource utilization. These pellets have high combustion efficiency and low pollutant emissions, providing new ideas for the development of new energy sources.

The flat die granulator‘s advantages also lie in its flexible operation. By simply replacing dies with different apertures, a wide range of pellet specifications can be produced to meet the needs of diverse industries. The equipment also occupies a small footprint and is easy to install and maintain, making it suitable for small and medium-sized enterprises. As the concept of green production becomes increasingly popular, the flat die pelletizer, with its high efficiency, energy conservation, and versatility, continues to provide a reliable solution for material forming in various fields.

What are the main components of an organic fertilizer production line?

by organic fertilizer production line

Those familiar with organic fertilizer production lines can generally identify their components, but for those new to the industry, this may seem a bit vague. Today, Zhengzhou Huaqiang Heavy Industry will share with you the components of an organic fertilizer production line.

The crushing section of an organic fertilizer production line. Given the diversity of user raw materials, our organic fertilizer production line equipment is designed with a crushing section. During the equipment sales process, we found that many users use relatively dry chicken manure or pig manure as raw materials, and some even mix in other raw materials to reduce organic fertilizer production costs. Raw materials with excessively large particle sizes cannot be directly granulated. Therefore, before granulation, the raw materials must be crushed to achieve the desired granulation effect before they can be fed into the organic fertilizer granulator. Of course, for users with sufficiently fine raw materials, this step can be omitted when designing organic fertilizer equipment.
The granulator section of an organic fertilizer production line is the core component of the equipment, making it an essential component. The model of granulator to be selected depends on the user’s production volume. The drying section of the organic fertilizer production line. The granulation process requires that the material humidity be kept below 25%. Therefore, raw materials with an initial humidity above 25% should first enter the drying process, and then enter the granulation process after the dried material reaches the required humidity. Of course, users with sufficient material humidity can omit this step when designing organic fertilizer equipment.
In other parts of the organic fertilizer production line, after the pelletizer completes the processing, it is conveyed by a belt conveyor to a ball shaping machine for shaping, achieving a perfectly spherical shape and forming organic fertilizer granules. For users who require it, we can design a final packaging process to directly package the final product, thus achieving perfect automation of the entire fertilizer granulation process.

How to choose a suitable fertilizer granulator?

by organic fertilizer production line

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..

How to choose between a rotary drum granulator and a disc granulator?

by organic fertilizer production line

In the fertilizer, feed and other industries, disc granulators and rotary drum granulators are both common granulation equipment, playing a key role in fertilizer production lines. Understanding their differences can help companies choose the right equipment and achieve efficient production.  From the working principle, when the disc granulator tilts the disc and rotates, the material continues to roll and agglomerate under the action of gravity, centrifugal force and friction. First, small particles are formed at the bottom of the disc, and then they continue to roll, absorbing the surrounding powder and gradually become larger. After reaching a certain size, they overflow from the edge of the disc to complete the granulation. The material of the rotary drum granulator rolls continuously in the rotating drum, and through water or steam, the basic fertilizer and other materials are fully reacted chemically in a wet environment, and the particles are agglomerated into balls under the extrusion force generated by the rotation of the cylinder. ​

In terms of equipment structure, the disc granulator is relatively simple. The core component is the tilted granulation disc, which is driven to rotate by the drive device. There are also disc inclination adjustment mechanisms, racks, feeding pipes, liquid sprayers, hanging plates, etc. The rotary drum granulator has a complex structure. The main body is a huge rotating cylinder, which is driven by a drive device. In addition, there are feeding systems, steam or gas supply systems, discharging systems, and complex control systems and auxiliary equipment such as temperature and humidity sensors. ​

The two have different focuses in their application areas. The disc granulator has a small investment and is easy to operate. It is a powerful assistant for small production plants and is widely used in small compound fertilizer plants, feed processing plants and small biomass fuel enterprises. The rotary drum granulator is like an industrial giant with high output and is suitable for large-scale production. It performs well in large-scale compound fertilizer and feed production enterprises and industrial raw material granulation processing. ​​

Disc granulators and rotary drum granulators have their own advantages and disadvantages. Enterprises must make comprehensive considerations and careful choices based on their own production scale, material characteristics, product quality requirements and budgets to win development opportunities in the fierce market competition.

How chicken manure is turned into fertilizer and the equipment used

by organic fertilizer production line

The large amount of chicken manure produced by chicken farms every day was once a headache for farmers – it piled up and occupied land, the odor disturbed people, and polluted the environment. Today, with the upgrading of environmental protection technology, chicken manure has transformed into high-quality organic fertilizer, and this “gorgeous transformation” is inseparable from the help of professional processing equipment.

The core of chicken manure turning into fertilizer is composting and fermentation. Fresh chicken manure contains a lot of pathogens, insect eggs, and a strong smell of ammonia nitrogen. Direct use will burn the roots of crops and attract pests and diseases. Therefore, the first step is to “disinfect and improve the quality” of chicken manure.

First, send the chicken manure to the dewatering machine to remove excess water. The dehydrated chicken manure cannot be fermented directly, but must be matched with straw and sawdust to adjust the air permeability and make the fermentation more complete.

The mixed materials are sent to the fermentation area, and the turning machine (such as the compost turning machine) is on the scene to turn the materials regularly to ensure sufficient air, so that the upper and lower layers are heated evenly to ensure the fermentation effect.

The fermented materials are crushed and agglomerated by a pulverizer, and the impurities are removed by a drum screener machine. The powdered organic fertilizer obtained can be used directly. If you want to improve storage stability and application convenience, you can perform granulation.

Granulation requires an organic fertilizer granulator to condense the powdered material into uniform particles. Granular fertilizer is not easy to absorb moisture and agglomerate, and it is resistant to loss during transportation and storage. When applied, the amount can be controlled to prevent waste. It can also slowly release fertilizer in the soil, prolong fertilizer effect, and improve crop absorption efficiency.

This system not only solves environmental problems, but also creates profits. Chicken manure organic fertilizer improves soil, improves the quality of fruits and vegetables, and is very popular.

From waste to “hot cakes”, the counterattack of chicken manure is clear. Choose professional equipment to turn chicken manure into treasure, protect green waters and green mountains, and collect gold and silver mountains. This is a wise choice for the circular development of modern agriculture.

The Core Value of Granulators in Fertilizer Production Lines

by organic fertilizer production line

Among the numerous pieces of equipment in a fertilizer production line, granulators are a key link in transforming raw materials into finished products, directly determining the fertilizer’s physical form and performance.

The primary function of a granulator is to process evenly mixed raw materials into granules of a specific size. Direct application of crushed and blended powdered raw materials can easily lead to problems such as clumping and flying. Granulators, however, use processes such as extrusion, rolling, or spraying to agglomerate the raw materials into 3-5 mm granules. This form facilitates transportation and storage, reduces waste, and controls the rate of nutrient release into the soil, preventing nutrient loss and improving nutrient utilization. For example, in compound fertilizer production, granulators precisely encapsulate elements such as nitrogen, phosphorus, and potassium, ensuring balanced nutrient release.

Granulators play an irreplaceable role in improving fertilizer quality. High-quality granulation equipment ensures uniform granules with a moderate hardness, neither too hard to break down nor too soft to cause pulverization. Take organic fertilizer as an example. In organic fertilizer production lines, the continuous temperature and pressure during the granulation process further kill pathogens and insect eggs in the raw materials, reducing the risk of crop disease. It also allows the organic matter to more tightly bind with the auxiliary materials, extending the fertilizer’s effectiveness.

Granulators are equally important for improving production efficiency. Modern equipment enables continuous operation, processing several tons of raw materials per hour. Combined with screening machines, they can separate unqualified granules in real time for secondary processing, reducing waste. Compared to traditional manual granulation, mechanical granulation reduces labor intensity and can be controlled through parameter adjustments to maintain stable quality, meeting the needs of large-scale production.

From an ecological perspective, granulators contribute to environmentally friendly fertilization. Granulated fertilizers reduce dust pollution and prevent powder drift. The slow-release granule design reduces the risk of soil compaction and water eutrophication caused by over-fertilization, supporting green agriculture.

Thus, granulators not only shape the fertilizer form but also safeguard its quality, occupying an unshakable core position in the fertilizer production line.
