Amid the rise of ecological agriculture and the continued surge in demand for organic fertilizer, new type organic fertilizer granulators, leveraging technological innovations from traditional equipment, have become key equipment for the fertilizer industry, addressing challenges in organic fertilizer granulation and promoting green production.
The most prominent advantage of the new type organic fertilizer granulator is its adaptability to organic fertilizer raw materials. Organic fertilizer raw materials, primarily derived from livestock and poultry manure, straw, and food waste, often exhibit large moisture fluctuations, high fiber content, and prone to clumping. By optimizing the conditioning system and granulation structure, the new equipment can flexibly adjust the raw material moisture and temperature. This allows for uniform granulation even with high-moisture, high-fiber raw materials, significantly improving granulation efficiency and effectively reducing raw material waste.
The new type organic fertilizer granulator is also known for its “green and efficient” design. By upgrading its transmission system and adding a dust collection device, the new equipment achieves low energy consumption and low pollution while improving production efficiency.
Furthermore, the new type organic fertilizer granulator can help enhance the competitiveness of organic fertilizer products. The organic fertilizer particles it produces have uniform density, moderate hardness, and are not easy to break; more importantly, the low-temperature granulation process of the new equipment can maximize the retention of beneficial microorganisms and active ingredients in the organic fertilizer, ensuring a longer-lasting fertilizer effect.
With the agriculture and fertilizer industries deeply intertwined, fertilizer form directly impacts fertilization effectiveness and industry efficiency. As the core equipment connecting fertilizer raw materials and finished products, fertilizer granulators are becoming a key driver of industry upgrades.
Fertilizer granulators transform powdered raw materials into uniform fertilizer granules through processes such as physical extrusion and conditioning. These granulated fertilizers are not only highly stable, making them suitable for long-term storage and long-distance transportation, but also enable a slow release of nutrients, extending the fertilizer’s effective lifespan and enabling more efficient crop absorption, thereby boosting agricultural production returns from the source.
Furthermore, the adaptability of fertilizer granulators meets the diverse needs of the industry. Whether producing organic fertilizers, compound fertilizers, or customized fertilizers for specific crops, the equipment can adapt to different raw material ratios by adjusting parameters. More importantly, modern fertilizer granulators continuously optimize energy efficiency, improving production efficiency while reducing energy consumption.
For fertilizer companies, fertilizer granulators are a powerful tool for enhancing product competitiveness. Against the backdrop of growing demand for high-efficiency fertilizers in agriculture, fertilizer granulators will undoubtedly drive fertilizer production towards greater efficiency, higher quality, and greater environmental protection.
To maximize the performance of a windrow compost turner, a scientific and standardized operating process must be followed. The entire process of the windrow compost turner revolves around four key steps: raw material pretreatment, windrow accumulation, turning and fermentation, and determination of maturity.
Raw material pretreatment is fundamental. Collected organic materials must first be sorted to remove impurities such as metal and plastic. Livestock and poultry manure should be air-dried to a moisture content below 65%, and straw should be pulverized to 5-10 cm in length. The raw materials should then be mixed at a carbon-to-nitrogen ratio of 25-30:1. The carbon and nitrogen content can be adjusted by adding straw or manure, ultimately achieving a moisture content of 55%-60%. At this point, the material will clump when held and fall apart upon contact, achieving optimal fermentation conditions. Next, the pre-treated raw materials are stacked into trapezoidal stacks at the fermentation site. These stacks are typically 3-5 meters wide at the base, 1.5-2.5 meters wide at the top, and 1-1.8 meters high. The stack length can be adjusted flexibly based on the site and production volume. A 1.5-2 meter passageway is left between the stacks to facilitate equipment access and ventilation.
Turning and tossing is a key step in fermentation. After starting the windrow compost turner, the depth of the tossing mechanism is adjusted according to the height of the stack, ensuring that the tossing teeth penetrate 10-20 cm into the bottom of the material. The initial fermentation lasts 1-3 days, with the first tossing occurring when the material temperature reaches 50-60°C. The high-temperature period lasts 4-10 days. When the temperature rises to 60-70°C, the stacks are tossed every 1-2 days to kill harmful bacteria. The cooling period lasts 11-20 days. When the temperature drops to 40-50°C, the stacks are tossed every 2-3 days to promote humus formation. The entire fermentation cycle lasts 15-25 days.
Finally, the material is judged by maturity. When the temperature is close to room temperature, the color is dark brown, the texture is loose, and there is no odor or earthy smell, it is considered mature and can be sent to the next stage for processing.
With the advancement of green agriculture, “environmental protection and resource utilization” have become core priorities in fertilizer production. Double roller press granulators (fertilizer compaction machines), with their outstanding environmental performance and resource utilization, have become key equipment for green fertilizer processing.
The double roller press granulator offers significant technological advantages in improving fertilizer quality. The fertilizer granules formed through physical extrusion have uniform density and high hardness, making them less prone to breakage and clumping during transportation and storage. More importantly, after application to the soil, these granular fertilizers release nutrients at a steady rate, extending their effective life and reducing the loss of nutrients such as nitrogen, phosphorus, and potassium through rainwater erosion.
The double roller press granulator’s environmental value is also reflected in its raw material processing and energy consumption control. The double roller press granulator can directly process agricultural waste such as fermented livestock and poultry manure, composted straw, and fruit and vegetable residues, transforming “waste” into high-quality organic fertilizer and achieving resource recycling. The equipment also eliminates the need for high-temperature drying, reducing emissions from coal or gas combustion. Its enclosed conveying design effectively controls dust spillage, improving the production environment.
Furthermore, its operation and maintenance requirements are low. Its simple structure and clear procedures allow workers to master the process after a short training period. Routine maintenance requires only regular inspection of the squeeze rollers for wear and cleaning of the feed channel, significantly reducing operational costs for small and medium-sized fertilizer companies.
On the stage of modern agriculture, NPK compound fertilizer has become a “nutrition master” for crop growth with its precise nutrient ratio and efficient fertilizer effect.

This comprehensive NPK fertilizer line integrates both chemical and organic components, sometimes even connecting with an organic fertilizer production line for enhanced soil benefits.
The transformation truly begins in the granulation phase, where specialized granulation equipment takes center stage. The versatilefertilizer granulator, particularly the efficient disc granulator, works its magic in the disc granulation production line. Through a fascinating process of agglomeration, raw powder is transformed into those uniform, plump fertilizer particles that farmers depend on for optimal crop nutrition.
Let’s explore this fascinating journey of NPK compound fertilizer manufacturing, where science and technology collaborate to create the essential nutrients that feed our world.
The Symphony of Precision Production
The production process of NPK compound fertilizer is like a carefully orchestrated symphony, with each step working in harmony to ultimately create a bountiful harvest. The entire process transforms powdered raw materials into uniform granules, making it particularly suitable for producing high-nitrogen products such as organic-inorganic compound fertilizers.
Imagine various basic fertilizer raw materials undergoing meticulous screening and crushing, much like musicians tuning their instruments in preparation for perfect harmony. These materials are then precisely measured and, according to scientific ratio requirements, systematically enter the mixing hopper through conveying and lifting equipment.
The Five-Step Granulation Magic
Fine Preparation
Each basic fertilizer is separately screened, with raw materials crushed and screened again to ensure particle uniformity. Screened materials are fed into corresponding hoppers, laying the foundation for precise proportioning.
Precise Proportioning
Through metering equipment, the feeding ratio of various basic fertilizers is precisely controlled, while recycled materials also enter the feeding hopper together with basic fertilizers through lifting devices, achieving resource recycling.
Moist Granulation
In the rotary drum granulator, the clever use of saturated steam not only raises material temperature but also moderately moistens it. When necessary, small amounts of water or fertilizer solution are added to maintain optimal granulation liquid phase conditions.
Rotational Forming
Utilizing friction generated by drum rotation, squeezing forces between material particles cause them to aggregate into balls. As the drum rotates, particles gradually roll toward the outlet along the inclined direction of the cylinder.
Refined Finished Product
After leaving the granulator, particles undergo drying, screening, cooling and other processes, ultimately being packaged and stored. Unqualified particles are crushed and returned as recycled materials for reprocessing.
Granulator: The Core Engine of Production
As key equipment in NPK fertilizer production, the rotary drum granulator employs wet granulation technology, demonstrating the sophistication of engineering. Its cylinder uses special rubber sheet lining or acid-resistant stainless steel lining to ensure equipment durability.
During granulation, auxiliary materials such as steam, gas ammonia, or added phosphoric acid and nitrogen solutions enable heated compound fertilizer granulation. This design not only improves production efficiency but also ensures product quality stability.

BB Blending Fertilizer Production Line – Meeting Diverse Needs with Flexible Formulas, Creating Agricultural Value with Precision Blending
In fertilizer production, the granulation process directly impacts fertilizer application convenience, storage stability, and nutrient utilization. Due to its unique technological advantages, double roller press granulators (commonly known as fertilizer compaction machines) are the preferred equipment for many production scenarios. They can transform a variety of fertilizer raw materials into uniform granules without complex pretreatment, offering both adaptability and practicality.
The operating principle revolves around “physical extrusion.” Crushed and mixed fertilizer raw materials are conveyed between two pairs of counter-rotating extrusion rollers at the core of the equipment. Under pressure from the roller surfaces, the raw materials are compressed into continuous flakes. These flakes then enter a crushing unit, breaking them into irregular particles. Screening equipment then selects the finished product that meets the required particle size.
The core advantages of double roller press granulators lie in their flexibility and energy efficiency. Requiring no binders, granulation relies solely on the raw materials’ inherent physical properties, preserving the natural properties of organic fertilizers or the nutrient purity of compound fertilizers. This eliminates the high-temperature drying step required in traditional granulation. Whether processing organic fertilizer, compound fertilizer, or functional bio-fertilizer, stable granulation can be achieved by simply adjusting parameters such as extrusion pressure and roller speed, providing an efficient solution for fertilizer production.
The core value of organic fertilizer lies in nutrient supply and convenient application, and granule shape directly impacts these two properties. Insufficient nutrient retention reduces fertilizer efficiency, while uneven granules increase the difficulty of field application. By optimizing process details, rotary drum granulators can reduce nutrient loss during the granulation process while creating granule shapes that meet field needs.
In terms of nutrient retention, the rotary drum granulator’s low-temperature granulation is particularly advantageous. Relying on physical tumbling to form granules, the granulator eliminates the need for high pressure and maintains an internal temperature below 35°C, maximizing the retention of active ingredients in the raw materials. Its nutrient retention rate is 5%-8% higher than that of traditional equipment.
In terms of granule application experience, granules produced by rotary drum granulators better meet field needs. On the one hand, the equipment can produce uniform granules with a diameter of 2-5mm by adjusting the drum speed and die aperture, making it easier for farmers to apply fertilizers using seed drills and reducing the unevenness of manual spreading. On the other hand, the moderate hardness of the granules (compressive strength of 10-15N) prevents them from breaking down during transportation and slowly disintegrates in the soil, achieving “slow-release fertilizer supply” and avoiding the root burn caused by concentrated nutrient release.
For organic fertilizer companies pursuing “high quality and low price,” the high-nutrient, easy-to-apply granules produced by the rotary drum granulator can significantly enhance their product’s market competitiveness.
In the fertilizer production industry, different types of fertilizer production lines correspond to varying production requirements and process characteristics. Understanding common fertilizer production line types and key equipment configurations is crucial for companies to plan production and improve efficiency.
Currently, mainstream fertilizer production lines include organic fertilizer production lines, NPK fertilizer production lines, and bio-organic fertilizer production lines. Organic fertilizer production lines primarily use agricultural waste and livestock manure as raw materials, producing organic fertilizer through fermentation, crushing, and granulation. NPK fertilizer production lines focus on optimizing the ratio of nitrogen, phosphorus, and potassium to produce compound fertilizers. Bio-organic fertilizer production lines build on traditional organic fertilizer production by incorporating biological strains to enhance the bioactivity of the fertilizer.
While different production lines have different focuses on equipment configuration, they share common core equipment. The crushing stage typically requires a fertilizer crusher to ensure the raw material particle size meets subsequent processing requirements. The granulation stage utilizes fertilizer granulators, such as disc granulators and rotary drum granulators. The mixing stage relies on a fertilizer mixer to ensure uniform mixing of the raw materials. Furthermore, fertilizer conveyors, screening machines, dryers, and coolers are essential equipment, collectively forming the complete fertilizer production process.
When configuring equipment, companies should carefully select equipment specifications and models based on the production line’s capacity, raw material characteristics, and product requirements to ensure optimal compatibility across all stages and improve overall production efficiency.
