In today’s agricultural sector, which strives for environmental protection and efficiency, the new type organic fertilizer granulator is redefining the production model for organic fertilizer with its innovative design. No longer a single “granulator,” it collaborates with multiple fertilizer equipment types to create a low-energy, high-yield, green production line. Shouldn’t this new equipment set a new benchmark for the industry?

The new organic fertilizer granulator’s unique features are quite striking. It utilizes low-temperature granulation technology to prevent high temperatures from destroying the beneficial microorganisms in the organic fertilizer, ensuring a longer-lasting fertilizer effect.Furthermore, its unique double axis mixer structure ensures more uniform mixing of raw materials, resulting in a pellet formation rate exceeding 96%. The pellets also possess a moderate hardness, making them both easy to transport and easily dissolve and absorb. Even more conveniently, the equipment is equipped with an intelligent control system that allows for real-time adjustment of speed and temperature, allowing operators to easily control production via a screen, significantly reducing labor costs.

Maximizing the value of the new organic fertilizer granulator requires the support of supporting equipment. Initially, the livestock and poultry manure processing machine separates impurities and moisture from the raw materials, providing high-quality raw materials for granulation. The fermentation turning machine, through aerobic fermentation, converts the raw materials into decomposed organic matter, reducing odor emissions.Later, a drum screener machine accurately selects qualified particles, returning the fine powder to the granulator for secondary use, achieving zero resource waste. A low-temperature dryer dries the fertilizer at temperatures below 40°C, further preserving its nutrients. Finally, an automatic metering and packaging machine quickly bags the fertilizer, ensuring a tolerance of no more than 50 grams per bag, meeting standardized production requirements.

With the growing global emphasis on ecological agriculture, this production line, comprised of a new organic fertilizer granulator and supporting equipment, not only addresses agricultural waste pollution but also provides high-quality organic fertilizer for the soil.

Key considerations for fertilizer coating machine selection

Written by fertilizer production line on September 26th, 2025. Leave a comment

When selecting a coating machine, fertilizer companies should consider their own production needs and focus on three key factors to avoid mismatching the equipment with their production.

First, consider compatibility with the particle characteristics. For large fertilizer particles (diameters over 5mm), a wide-channel coating machine with an anti-sticking guide structure is recommended to prevent particle accumulation and blockage within the channel. For particles with high moisture content (above 12%), a conveyor assembly with an anti-stick coating is preferred. For organic fertilizer particles containing fibrous impurities, it is also important to confirm whether the coating machine is equipped with a pre-filter to prevent impurities from entanglement with mechanical components.

Second, consider capacity compatibility. For small-scale production (daily production capacity under 50 tons), a batch coating machine can be selected, offering flexible batch adjustments and suitable for producing a variety of fertilizers in small batches. For large-scale production (daily production capacity over 100 tons), a continuous machine is recommended to ensure that the conveyor speed is synchronized with the material feed rate.

Finally, consider the compatibility of the coating material. If using PE film, confirm that the equipment’s heat-sealing temperature range covers 100-130°C. If using functional coating materials (such as films containing anti-caking agents), check that the equipment’s tension system supports low-tension adjustment to avoid film breakage and impacting performance. Additionally, pay attention to the equipment’s adaptability to film widths and whether it can be flexibly adjusted to accommodate different packaging specifications, minimizing material waste due to film mismatches.

Working principle of a drum fertilizer cooler: Understanding the core logic of material cooling

Written by fertilizer production line on September 26th, 2025. Leave a comment

In industrial production, directly stacking high-temperature materials after processing can easily lead to problems such as agglomeration and deterioration. Drum fertilizer coolers are key equipment for addressing this problem. So how do they achieve efficient cooling? Today, we’ll examine their core operating principles from both a structural and process perspective.

The core structure of a drum fertilizer cooler consists of an inclined drum body, a transmission system, a cooling system, and a discharge mechanism. During operation, hot materials enter through the feed port at the upper end of the drum. The transmission system drives the drum to slowly rotate, causing the materials to continuously tumble and move forward within the drum as it rotates.

The cooling system achieves cooling through two methods: one is a cooling jacket installed on the drum shell, through which cold water or air flows, removing heat from the material through heat conduction; the other is a direct flow of low-temperature gas into the drum. The gas fully contacts the hot material, absorbing heat through heat exchange, and is then discharged through the exhaust port. Throughout the entire process, the material is tumbled to ensure uniform heating and avoid incomplete cooling. The drum fertilizer cooler’s tilt angle and rotational speed control the material’s residence time, allowing for flexible adjustment based on the cooling requirements of different materials.

Finally, the cooled material is discharged from the discharge port at the lower end of the drum, completing the cooling process. Whether it’s granular, powdered, or small chunks, this cooling method delivers efficient and stable cooling, widely applicable to production needs across multiple industrial sectors.

The new type two-in-one organic fertilizer granulator’s complete operating process.

Written by fertilizer production line on September 25th, 2025. Leave a comment

The new type two-in-one organic fertilizer granulator features an integrated “mixing + granulation” design, simplifying organic fertilizer production. Its operations are centered around four core steps, ensuring pellet quality and efficiently supporting the organic fertilizer production line.

The first step is raw material pretreatment. Fermented organic fertilizer (such as livestock manure and composted straw) must first be crushed to a 40-60 mesh fine powder with a moisture content of 25%-35%. Excessively coarse raw materials will result in uneven granulation, while inappropriate moisture content will affect the final product. Meeting pretreatment standards is essential for stable equipment operation.

The second step is the core mixing process. Pretreated raw materials enter the integrated mixing system. A high-strength alloy steel agitator shaft drives the wear-resistant blades, while a variable frequency motor precisely controls the speed between 20-60 rpm. If binders such as bentonite are required, they are added simultaneously. The blades shear and stir the powder, achieving over 90% mixing uniformity within 5-10 minutes, preventing uneven nutrient distribution in the pellets.

The third step is targeted granulation. The mixed material automatically enters the granulation system, where the equipment changes its forming method based on the raw material’s characteristics. Highly viscous raw materials (such as chicken manure organic fertilizer) use a stirring granulation mechanism, where paddles knead the material into 2-4mm pellets. High-fiber raw materials (such as straw organic fertilizer) use a roller-type granulation mechanism, where die extrusion forms the pellets. The stainless steel disc can be hydraulically adjusted from a 30° to 50° tilt angle, and a wear-resistant rubber lining reduces sticking to the wall. The pellet formation rate exceeds 90%, and the pellets are uniformly shaped.

Finally, the screen residue is recycled and connected. After granulation, the pellets pass through an integrated screening device. Qualified pellets enter the drying stage (dried to a moisture content of less than 10%), while substandard fines are returned to the mixing system through a recirculation channel for processing with new raw materials. This design achieves a raw material utilization rate exceeding 95%, reducing waste and ensuring continuous production.

The entire process eliminates the need for frequent manual handling. The new type two-in-one organic fertilizer granulator can complete the entire process from raw material input to qualified pellet output, significantly improving the efficiency and convenience of organic fertilizer production.

Reasons for the Growing Demand for Bio-Organic Fertilizer Production Lines

Written by fertilizer production line on September 25th, 2025. Leave a comment

As agriculture moves toward green and sustainable development, demand for bio-organic fertilizer production lines is growing rapidly, primarily due to the following key factors.

Policy guidance is a key driver. Many countries have introduced specific policies to support the development of the bio-organic fertilizer industry. For example, the European Union has implemented a “Farm to Fork” strategy, which explicitly calls for reducing the use of chemical fertilizers. It subsidizes farms that use bio-organic fertilizers and offers tax breaks to bio-organic fertilizer manufacturers. For example, Germany exempts bio-organic fertilizer manufacturers that meet environmental standards from some corporate income tax. The United States has established a special fund to support the construction of bio-organic fertilizer production lines and has enacted regulations to strictly restrict the indiscriminate disposal of agricultural waste. This has encouraged farms and businesses to transform livestock and poultry manure, crop straw, and other products into usable resources through bio-organic fertilizer production lines, reducing pollution while creating economic value. Evolving market demand is also crucial.

With rising consumption, green and organic agricultural products are gaining popularity, with their market size growing at an average annual rate of 10%. Bio-organic fertilizers can improve the quality of agricultural products, increase the vitamin C content of fruits and vegetables, and eliminate the “chemical fertilizer smell,” thus meeting market demand for high-quality agricultural products. Furthermore, long-term use of chemical fertilizers has led to soil compaction and a decrease in organic matter. Bio-organic fertilizers, with their ability to loosen the soil, replenish carbon sources, and inhibit soil-borne diseases, are urgently needed for soil remediation. Furthermore, the growth of large-scale agriculture has significantly increased demand for bio-organic fertilizers from planting bases and family farms, prompting companies to expand production capacity.

Technological advances have provided strong support for the development of bio-organic fertilizer production lines. Automated production lines have improved production efficiency, reduced labor costs by over 60%, and lowered energy consumption by 20%-30%. Advanced bacterial strains and processes have significantly improved product quality and significantly increased the number of viable bacteria. Intelligent management enables full control of the production process, attracting more companies to participate.

Furthermore, abundant and affordable raw materials provide cost advantages for bio-organic fertilizer production lines, and companies can also receive environmental protection incentives for waste disposal. Faced with market saturation and regulatory pressure, traditional chemical fertilizer companies have shifted to the bio-organic fertilizer business. The continuous influx of new players has further increased demand for production lines.

Organic Fertilizer Production Lines: Does Raw Material Determine Success or Failure?

Written by fertilizer production line on September 25th, 2025. Leave a comment

Starting an organic fertilizer production line involves more than just purchasing equipment—it hinges on two crucial factors: raw material supply and fermentation technology. Failure in any of these steps can lead to substandard product or even stagnation.

Understanding the fundamental differences between raw material requirements for NPK and organic fertilizer production lines is essential for planning a successful operation.

NPK Fertilizer Production

Requires precisely measured chemical compounds—primarily nitrogen (N), phosphorus (P), and potassium (K) sources. These mineral-based ingredients need exact proportioning to achieve specific nutrient ratios.

Organic Fertilizer Production

Depends on organic waste materials like animal manure, crop residues, and food waste. These materials require proper composting and fermentation to stabilize nutrients and eliminate pathogens.

Essential Equipment for Fertilizer Production

Beyond raw material considerations, selecting the right machinery is critical for efficient production:

Fertilizer Mixer Machine

Ensures homogeneous blending of ingredients for consistent nutrient distribution

Fertilizer Granulator

Transforms mixed materials into uniform pellets for easier handling and application

Fertilizer Packing Machine

Automates the final packaging process, ensuring proper sealing and accurate weights

Successful fertilizer production—whether organic or NPK—requires careful consideration of both raw material specifications and appropriate equipment selection. The fertilizer mixer machine, fertilizer granulator, and fertilizer packing machine work together to transform raw materials into market-ready products, but their effectiveness depends entirely on proper raw material preparation and processing techniques.

Raw materials are the lifeblood of organic fertilizer.

These production lines rely on livestock manure, crop straw, and agricultural waste—materials that must be abundant and local. Imagine building a production line in an area with few farms: transporting manure from 100 kilometers away would increase costs by 30-40%, eroding profits. Conversely, a plant located near poultry farms or rice paddies would thrive: fresh manure (rich in nitrogen) and straw (rich in carbon) create the perfect nutritional combination, while short transportation distances reduce the risk of spoilage.

Fermentation technology is equally crucial.

The value of organic fertilizer lies in its nutrient content and microbial activity, both of which rely on controlled decomposition. A poor fermentation process—overheating, overcooling, or insufficient aeration—can harbor harmful pathogens or reduce nitrogen content by 20% or more. Established production lines use automated compost turners to regulate temperature (55-65°C, optimal for weed control) and aeration, ensuring consistent nutrient levels (typically 3-5% total nitrogen, phosphorus, and potassium) and meeting organic certification standards.

Where do these lines thrive?

In regions with strict environmental regulations and a thriving organic agriculture sector. Take Yunnan’s tea-producing regions, for example: strict restrictions on chemical inputs drive demand for organic fertilizers, while local bamboo and tea waste provide a stable source of raw materials. Similarly, in Zhejiang’s vegetable hubs, consumers pay premium prices for organic produce, making organic fertilizer lines not only compliant but also highly profitable.

In short, organic fertilizer lines succeed when raw materials are sourced locally and the fermentation process is precise. It’s a marriage of geography and technology—a combination that, when chosen correctly, nourishes the crop while generating profit.

Analysis of Common Risks in Organic Fertilizer Production Lines

Written by fertilizer production line on September 25th, 2025. Leave a comment

Organic fertilizer production lines rely on agricultural waste conversion to achieve resource recycling, but their production processes are complex and susceptible to internal and external factors. They face multiple risks and challenges, requiring accurate identification and proactive prevention.

Raw material supply risks are the primary obstacle to production line operations. Organic fertilizer raw materials primarily consist of livestock and poultry manure and crop straw, which are significantly constrained by natural and social factors. Seasonal variations can lead to a “peak season surplus” and “off-season shortage” in straw supply, such as abundant straw after the autumn harvest and a tight supply in the spring. Sudden animal epidemics can cause farm closures, directly cutting off the source of livestock and poultry manure. Furthermore, raw material quality fluctuates significantly. Excessive levels of heavy metals in manure or moldy straw can result in substandard quality in the finished organic fertilizer, impacting sales and potentially leading to environmental complaints.

Equipment operation risks directly threaten production continuity. Organic fertilizer production lines involve multiple processes, including fermentation, crushing, granulation, and drying. Long-term, high-load operation of core equipment can lead to malfunctions. Leaks in the hydraulic system of the fermentation granulator can lead to uneven granulation and prolonged composting. Wear on the granulator’s molds can reduce pellet formation and increase raw material loss. Failure of the dryer’s hot air furnace can result in incomplete drying of the material, leading to caking and deterioration. If critical equipment shuts down, the entire production line can be paralyzed, resulting in significant economic losses.

Production safety risks harbor significant hidden dangers. During the fermentation process, microorganisms decompose organic matter, producing gases such as methane and ammonia. Methane is flammable and explosive. If the workshop is poorly ventilated and concentrations exceed standards, it can easily cause an explosion when exposed to open flames. The drying process uses high temperatures, making excessively thick material accumulation or improper temperature control a fire hazard. Furthermore, some equipment components lack effective protection, and improper operator operation can lead to mechanical injuries.

External environmental risks should also not be underestimated. At the market level, the demand for organic fertilizers is affected by the agricultural production cycle. During the peak season, products are in short supply, while during the off-season, inventory is piling up and prices fluctuate sharply. At the policy level, upgraded environmental protection standards may require production lines to increase investment in pollution control equipment. Adjustments to agricultural subsidy policies will directly affect product market competitiveness. If organic fertilizer production lines fail to adapt to policy changes in a timely manner, they may face compliance risks and operational pressures.

How Can Tiny Pellets Shape the Future of Agriculture?

Written by fertilizer production line on September 25th, 2025. Leave a comment

On the stage of agricultural and industrial production, the double roller press granulator stands out as an indispensable star equipment, thanks to its exquisite fertilizer granules compaction technology. This highly efficient organic fertilizer manufacturing machine transforms raw materials into invaluable pellets through a series of precise operations, injecting strong momentum into sustainable development.

The entire process begins with careful material preparation. Raw materials undergo pre-treatment such as crushing, mixing, and appropriate humidification to enhance their plasticity and flowability, laying a solid foundation for subsequent extrusion granulation. The pre-treated material is then evenly fed between two rotating pressure rollers through a feeding device, ensuring continuous and uniform distribution to maintain the stability of the granulation process.

When the material enters the narrow gap between the two rollers, high-pressure extrusion takes center stage. The rollers typically rotate in opposite directions, compacting and pushing the material forward under pressure. At this stage, the fertilizer compaction machine plays a critical role: the gaps between particles decrease, and the material is compacted into a sheet-like or strip-shaped structure with a certain thickness. This plastic deformation allows the material to maintain its shape under high pressure without immediate collapse.

The extruded sheet or strip material is then sent to a crushing device, such as a crushing drum or cutting blade, where it is broken into small pieces. These pieces are further reduced to particles of the desired size through mechanical force during subsequent screening and cooling processes. Finally, the formed particles are cooled to stabilize their structure, and unqualified particles are removed through screening to ensure uniform particle size in the final product.

The double roller press granulator is not only a perfect embodiment of technology but also a powerful engine driving a greener future.

Analysis of Key Equipment in NPK Fertilizer Production Lines

Written by fertilizer production line on September 25th, 2025. Leave a comment

In the transformation of NPK fertilizers from raw materials to finished products, key equipment is central to ensuring precise nutrient distribution and high-quality pellets. The core equipment in a complete NPK fertilizer production line can be categorized into three main processes: pretreatment, processing, and post-processing. Each device has a unique mission.

In raw material pretreatment, the crusher and batching system are the first checkpoints. NPK raw materials (such as urea and monoammonium phosphate) are often in lumpy form. The crusher must crush them into a uniform powder of less than 1mm. Uneven particle size can lead to inadequate mixing and result in significant nutrient variations within a single bag of fertilizer. The automatic batching system acts like a “precise steward,” blending nitrogen, phosphorus, and potassium raw materials and auxiliary materials according to a preset NPK ratio (such as 15-15-15), maintaining an error within 0.5%. This is crucial for ensuring that the fertilizer’s nutrient content meets standards.

In the core processing phase, the mixer and granulator are the “heart” of the production line. A twin-shaft mixer uses counter-rotating blades to blend various raw materials for 3-5 minutes, achieving a consistent NPK content per gram. Insufficient mixing time can result in areas with high nitrogen and low phosphorus content, impacting crop absorption. The granulator determines the fertilizer’s form. A rotary drum granulator is suitable for large-scale production. The rotating drum tumbles the material, combined with water mist wetting, kneading the powder into round granules with a diameter of 2-4mm. This creates a good appearance and facilitates mechanized fertilization. An double roller perss granulator, which forms the granules through a die without drying, is suitable for small-scale production lines producing high-concentration fertilizers. However, the granules are irregular and more suitable for customized small-batch production.

In the post-processing stage, the dryer, cooler, and coating machine are “quality guardians.” The dryer uses hot air drying technology to reduce the moisture content of the granulated wet granules from 20% to below 8%. Excessive moisture content can lead to caking and mold. The cooler cools overheated fertilizer granules to a suitable temperature. The coating machine sprays paraffin wax or kaolin to form a protective film on the surface of the granules, preventing clumping during storage and transportation, extending shelf life, and reducing dust pollution during fertilization.

These key equipment are closely linked and together determine the quality, yield, and stability of NPK fertilizers, making them indispensable components of the NPK fertilizer production line.
