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.

by organic fertilizer production line

The organic fertilizer production line specializes in transforming livestock manure and agricultural waste into nutrient-rich organic matter through fermentation and composting processes. This eco-friendly system not only recycles waste but also improves soil structure and microbial activity, making it fundamentally different from chemical fertilizer production in both raw materials and environmental benefits.

While the organic fertilizer line focuses on natural decomposition processes, the NPK fertilizer production line chemically synthesizes precise nitrogen, phosphorus, and potassium ratios. The key distinction lies in their production philosophy – organic lines emphasize sustainable recycling of biological waste, whereas NPK lines prioritize exact nutrient formulations for specific crop requirements.

Gold in Waste

Traditionally viewed as mere disposal challenges, livestock manure and agricultural waste are being transformed into genuine treasures through modern organic fertilizer production lines. These potentially polluting materials miraculously become nutrient-rich organic fertilizers through advanced fermentation and granulation processes, achieving perfect resource recycling.

The Dual-Benefit Environmental Solution

This innovative production system creates astonishing dual benefits: enterprises gain substantial economic returns while the planet receives valuable environmental dividends. Each organic fertilizer production line quietly contributes to reducing greenhouse gas emissions and improving soil quality – this “profitable yet eco-friendly” model represents the best practice of sustainable development.

Technology Reshaping Agriculture

Modern organic fertilizer production lines employ automated control systems and precision equipment, elevating traditional composting to industrial standards. From raw material pretreatment and high-temperature fermentation to final granulation and packaging, the entire process is both efficient and clean. The produced granular organic fertilizers feature balanced nutrients and convenient transportation/application, completely transforming the “dirty and messy” image of traditional organic fertilizers.

Vanguard of Global Environmental Engineering

As nations worldwide seek environmental solutions, organic fertilizer production lines demonstrate remarkable potential. Estimates suggest that processing one ton of agricultural waste can reduce approximately 0.5 tons of carbon emissions. As more enterprises join this movement, we see not just business opportunities, but hope for harmonious coexistence between humanity and the environment.

The Green Choice for Tomorrow

With the rise of organic farming and growing consumer environmental awareness, market demand for organic fertilizers is rapidly increasing.

The Heartbeat of Fertilizer Production

by organic fertilizer production line

A windrow compost turning machine is a type of composting machinery specifically designed for aerobic fermentation of organic materials. It’s part of the equipment required for biofertilizer production, which typically includes a mixer, fermenter, grinder, and granulator. As a key component of fertilizer equipment, a windrow compost turning machine specializes in organic waste treatment, distinguishing itself from chemical fertilizer machinery in its focus on bio-organic material processing. Its crawler design provides stability and maneuverability for large-scale composting operations within a complete fertilizer production system.

The Central Nervous System

Imagine pretreated materials as ingredients waiting to be cooked, and the windrow compost turning machine as the chef mastering the heat. It precisely turns 2-meter-high organic windrows, much like a chef stir-frying dishes, ensuring every part gets even “heating.” This mechanical ballet can process thousands of tons daily, delivering perfectly fermented materials for subsequent granulation and drying processes.

The Metronome of Mass Production

In large fertilizer plants with annual outputs exceeding 50,000 tons, multiple windrows align like piano keys. The crawler turner moves like a skilled pianist, cycling through different zones following the composition of “fresh material loading – thermophilic fermentation – cooling maturation.” This “multi-zone rotation” enables 24/7 continuous production, transforming organic fertilizer making into true industrial assembly lines.

Did you know? Modern crawler turners’ intelligent control systems allow operators to adjust travel speed and turning frequency as precisely as a car’s accelerator via touchscreens. When downstream granulators speed up, the fermentation rhythm follows in real-time, ensuring the entire production line harmonizes like a symphony orchestra.

The Versatile Performer

Unlike fixed fermentation equipment, crawler turners can either coordinate seamlessly with other devices in modern plants or work solo in open fields. When farms need onsite manure treatment or cities must handle sudden garden waste, this steel giant can “relocate,” bringing production lines to materials rather than the opposite.

From farms to cities, windrow compost turning machines are redefining possibilities in organic fertilizer production. More than just bridges connecting pretreatment and refining processes, they’re alchemists transforming organic waste into black gold. In today’s sustainability-focused world, these flexible, efficient machines have become indispensable hearts of modern fertilizer production lines.

Roller Press Granulator Line: How Do Core Components Work Together?

by organic fertilizer production line

The “NPK Fertilizer Roller Press Granulator Production Process” (or “Roller Press Granulator Line”) refers specifically to the dry granulation method using roller compaction in NPK fertilizer production, which is one approach within the broader “NPK manufacturing process” that includes various production methods. The “NPK fertilizer granulator machine” is the core equipment that physically forms the granules in this process line. Thus, the granulator machine operates within the roller press production line, which itself constitutes one segment of the complete NPK manufacturing process encompassing raw material preparation, mixing, granulation, drying, screening, and packaging.

1. Raw Material Pretreatment Equipment

The frontline of the production line, typically including a crusher and screening machine. The crusher reduces raw materials to granulation-suitable fineness (usually 0.1-3mm), while the screening machine acts as a strict quality inspector, removing impurities and non-compliant particles to provide “carefully selected” materials for subsequent processes.

2. Roller Press Granulator

The “heart” of the entire system. Two high-hardness alloy rollers rotate oppositely under tremendous pressure (50-200MPa), compressing materials into dense strips or sheets. Rotary blades on the granulator then cut these into uniformly sized particles – a process reminiscent of making perfect pasta.

3. Crusher (Optional)

The “troubleshooter” of the production line, specifically handling large lumps generated during extrusion. Through high-speed rotating hammers or blades, it breaks these “nonconforming” chunks into standard sizes, ensuring product consistency.

4. Screening Machine

The final quality checkpoint. Featuring multi-layer vibrating screens, it precisely separates oversized or undersized particles with over 95% pass rate for qualified products. Removed materials can be recycled back into the system, achieving zero-waste production.

5. Packaging Equipment

The terminal station of the production line. Fully automatic packers complete weighing, bagging, sealing, and coding in one sequence. Modern machines equipped with photoelectric sensors and servo control systems achieve ±0.5% packaging accuracy, handling hundreds of packaging units per hour.

6. Control System

The “brain” of the entire line. The PLC control system monitors key parameters like pressure, temperature, and rotation speed in real-time through dozens of sensors, automatically adjusting equipment operation. Operators can easily set and adjust process parameters via touchscreen interfaces, enabling “one-touch” intelligent production.

This highly integrated system achieves seamless transition from raw materials to finished products through perfect coordination of all components. It offers not only high production efficiency but also stable product quality, making it the preferred solution for modern powder granulation processes.

The unique features of the roller press granulator production line

by organic fertilizer production line

The roller press granulator production line is specially designed for compound fertilizer production. With its core advantages of precise proportioning and efficient granulation, it has become an ideal choice for balancing nutrients and improving fertilizer efficiency, injecting strong momentum into the company.

Its core competitiveness lies in its precise control of compound nutrients. The automatic batching system precisely blends nitrogen, phosphorus, potassium, and trace elements according to crop needs. The double axis mixer quickly blends the raw materials, preventing uneven nutrient distribution and laying a foundation for high-quality granulation.

The granulation process offers unique advantages. The double roller press granulator uses counter-rotating high-strength rollers to squeeze the material into thin flakes, which are then crushed and screened to form uniform granules. No binders are required, and the purely physical action preserves nutrient activity. The granules are high in hardness and have a controllable dissolution rate, meeting the needs of different soils and crops, thereby improving fertilizer utilization.

The production line features a compact, efficient, and adaptable process. From raw material proportioning and mixing to granulation and screening, each step is seamlessly integrated, forming a continuous closed loop. For high-concentration, slow-release, and controlled-release compound fertilizers, granule specifications can be adjusted by adjusting the roller pressure and speed to meet diverse needs. A return system returns unqualified granules back to the production line, improving raw material utilization and reducing production costs.

The equipment offers outstanding stability and environmental friendliness. The rollers are made of a wear-resistant alloy and undergo a special heat treatment for corrosion resistance, resulting in a long service life and minimal maintenance. Production is wastewater-free, and dust is collected and treated for discharge, meeting environmental standards. The intelligent control system enables visual parameter adjustment, and one-button start and stop operations reduce operational barriers, making large-scale production easy for even small and medium-sized enterprises.

As the compound fertilizer market pursues precise nutrient delivery and efficient application, the roller press granulator production line, with its stable quality, flexible production, and cost-effectiveness, has become a key piece of equipment for enhancing companies’ competitiveness, helping compound fertilizers realize greater value in modern agriculture.

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.

Harmless treatment of agricultural organic wastes with bio organic fertilizer equipment

by organic fertilizer production line

The combined application of organic fertilizer and chemical fertilizer can improve the utilization rate of fertilizer. Chemical fertilizer has high nutrient content per unit, few components and quick release, belonging to quick acting fertilizer; Organic fertilizer contains a lot of nutrients, but the relative content is low, and the release is slow. It is a long-term fertilizer. In order to maintain the self-sustaining ability of nutrients and soil fertility, and strengthen the recycling and reuse of soil nutrients, organic fertilizer and chemical fertilizer should be applied in a reasonable way to complement each other, so as to combine the long and short fertilizer effects, which is more conducive to the absorption of crops, provide nutrients for crops, and improve the utilization rate of fertilizers.

Organic fertilizer equipment makes agriculture more and more green. For the farm, if the chicken manure, pig manure and other excrement are not treated in time, it will cause great pollution to the environment, especially to the surrounding air and soil, and bring trouble to the surrounding residents. In fact, animal manure is a good organic fertilizer. Processing animal manure into efficient organic fertilizer through organic fertilizer equipment can increase income while protecting the environment!
Organic fertilizer equipment has truly realized the development of agricultural cycle. The new organic fertilizer production line technology is more conducive to the harmless treatment of agricultural organic wastes by using bio organic fertilizer equipment. For the fermentation treatment of organic manure compost, the organic manure equipment is used to treat organic manure, which does not necessarily need livestock manure, chicken manure and pig manure. Wheat straw and corn straw mixed farm manure, pig manure and pig manure can also be added, and the organic manure production equipment is used for harmless treatment. Microbial organic fertilizer fermentation bacteria are added for composting fermentation, and the organic fertilizer granulator produces microbial organic fertilizer. The organic fertilizer production equipment is an ideal harmless treatment method for agricultural wastes.

What equipment does the organic fertilizer production line mainly consist of

by organic fertilizer production line

Users who know and are familiar with the organic fertilizer production line can probably tell how many parts the organic fertilizer production line consists of, but it seems a bit vague to friends who are new to this industry. Today Zhengzhou Huaqiang Heavy Industry will share with you the organic fertilizer production line. What are the parts?
The pellet machine part of the organic fertilizer production line equipment, the core part of the organic fertilizer production line equipment is granulation, so the fertilizer pellet machine is indispensable. The model selection of the pellet machine is determined according to the user’s output.

The other parts of the organic fertilizer production line equipment, after the granules are machined, are conveyed to the disc shaping machine through a belt conveyor to shape the granules, and the granules have reached the perfect spherical shape of organic fertilizer granules. For users in need, we will be at the end design a packaging link to directly package the final finished product, which has perfectly realized the automatic production of the entire fertilizer granulation process.
The crushing part of the organic fertilizer production line equipment. In view of the diversity of users’ raw materials, our organic fertilizer production line equipment is designed with a crushing part. In the process of equipment sales, we found that many users used relatively dry chicken manure or pig manure as raw materials, and some users even mixed some other materials to reduce the production cost of organic fertilizer. And we know that materials with too large diameter cannot be directly granulated. Therefore, before granulating, we need to pulverize the raw materials to achieve the granulation effect, and the pulverized materials can enter the organic fertilizer granulator. Of course, users with sufficient material fineness can omit this link when designing organic fertilizer equipment.
Drying part of organic fertilizer production line equipment. The prerequisite of the granulation mechanism is that the humidity of the material should be controlled below 25%. Therefore, for some raw materials with an initial humidity above 25%, they should enter the drying process first, and then enter the granulation mechanism after the dried material reaches the corresponding humidity. Of course, users with sufficient material humidity can omit this link when designing organic fertilizer equipment.
