Analysis of Major Fertilizer Production Processes

fertilizer granulator Nov 20, 2025

Chemical fertilizers are crucial supports for modern agricultural production. Understanding the production processes of different fertilizers not only helps in their proper use but also promotes the sustainable development of the fertilizer industry. This article details the industrial production processes of several major fertilizers.

Ammonium Phosphate Fertilizer Production Process

The production of monoammonium phosphate (MAP) and diammonium phosphate (DAP) primarily uses the wet process phosphoric acid method. First, phosphate rock is treated with sulfuric acid to obtain phosphoric acid, which is then reacted with ammonia under different conditions. Monoammonium phosphate is formed under acidic conditions, while diammonium phosphate requires controlling the pH at a higher level. The resulting slurry undergoes granulation, drying, screening, and other processes to ultimately produce granular products.

Ammonium Sulfate and Compound Fertilizer Production

Ammonium sulfate mainly comes from by-products of the coking industry and flue gas desulfurization, but can also be produced synthetically. The synthetic method involves the direct reaction of ammonia with sulfuric acid, followed by crystallization, separation, and drying. The production of NPK compound fertilizers is more complex, requiring precise proportional blending of various basic fertilizers according to formulations, then manufacturing through blending or chemical synthesis.

Modern compound fertilizer production mostly uses the slurry method or melt method. The slurry method involves making raw materials into a slurry followed by spray granulation, while the melt method melts the materials and granulates them through nozzles. Both methods can produce high-quality compound fertilizers with uniform nutrients and high particle strength.

Phosphate and Potassium Fertilizer Production Processes

Superphosphate is produced by decomposing phosphate rock with sulfuric acid. The production process requires controlling sulfuric acid concentration and reaction temperature to ensure complete decomposition of phosphate rock. The reacted material needs a period of curing to meet standard requirements for available phosphorus content.

Potassium fertilizer production mainly relies on the mining and processing of potash salt deposits. Potash salts are obtained through solution mining or traditional mining methods, then purified through flotation, crystallization, and other processes. Different types of potassium fertilizers require different subsequent processing methods. For example, potassium chloride mainly uses flotation and recrystallization, while potassium sulfate requires the Mannheim process or sulfuric acid decomposition method.

Sulfur Production and Processing

Sulfur mainly comes from by-products of natural gas purification and petroleum refining, but can also be extracted from pyrite. The Claus process is the primary method for sulfur recovery, obtaining elemental sulfur by oxidizing hydrogen sulfide gas. The produced sulfur must undergo melting, purification, and molding processes before it can be used as agricultural sulfur.

In fertilizer production, sulfur is not only a raw material for certain fertilizers but also commonly used to adjust soil pH. In recent years, with the development of slow and controlled-release technologies, the production process of sulfur-coated fertilizers has become increasingly mature, significantly improving fertilizer utilization efficiency.

The continuous innovation and improvement of fertilizer production processes have not only enhanced fertilizer quality and utilization efficiency but also reduced environmental impact. In the future, with the development of green manufacturing technologies, fertilizer production will become more efficient and environmentally friendly, providing stronger support for global food security.

In conclusion, modern fertilizer manufacturing represents a sophisticated integration of chemical processing and mechanical engineering. The npk fertilizer manufacturing process has evolved to incorporate advanced equipment like the npk blending machine for precise formulation and specialized npk fertilizer granulator machine for particle formation. The complete npk fertilizer production line typically includes fertilizer mixer machine for homogeneous blending, disc granulator machine for efficient fertilizer granulation, and screening systems for quality control. Modern npk granulation machine technology offers multiple approaches, from bulk blending fertilizer machine systems to advanced disc granulator equipment, each suited for different production requirements. The entire npk production process demonstrates remarkable precision in transforming raw materials into nutritionally balanced fertilizers. As the industry advances, the manufacturing of npk fertilizer continues to optimize through improved npk fertilizer machine designs and processing techniques, ensuring efficient production of high-quality fertilizers that support global agricultural needs while complementing sustainable practices like fermentation composting technology for organic fertilizer in integrated soil management systems.

Ring Die Pelleting Machine: The Industrial Alchemy of Fertilizer

fertilizer granulator Nov 20, 2025

 In modern fertilizer production lines, the ring die pelleting machine works like a master magician, miraculously transforming various raw materials into uniform fertilizer pellets. Each step of this industrial magic show contains exquisite process wisdom.

Raw Material Metamorphosis

Organic materials first undergo a 30-45 day fermentation “aging period,” then are ground into 60-100 mesh powder as fine as flour. For compound fertilizer ingredients, NPK nutrients are measured with perfume-maker’s precision, requiring over 90% mixing uniformity and moisture strictly controlled within the golden 8%-15% range.

Conditioning: The Material Spa

Pretreated materials enter the conditioner for a steamy 60-80℃ spa treatment. Moisture is precisely adjusted to 12%-18%, making materials soft and sticky – like well-kneaded dough – perfectly prepared for granulation.

High-Pressure Extrusion: Birth of Pellets

Conditioned materials enter the “pressure chamber” between ring die and rollers, enduring 20-50MPa pressure – equivalent to 200-500kg force on a fingernail-sized area. Under this force, materials transform into uniform columns through precision die holes.

Precision Cutting & Cooling

Freshly extruded columns immediately meet high-speed rotating blades, being cut into 2-10mm pellets with under 0.3mm length variation. These “newborns” then enter cooling systems, gently air-dried to prevent agglomeration from residual heat.

Quality Screening & Packaging

Vibrating screens act as strict quality inspectors, removing oversized, undersized or broken pellets, typically achieving over 95% qualification rate. Perfect pellets are finally bagged, ready to fulfill their mission of nourishing crops and improving soil.

In conclusion, the ring die pelleting machine represents just one sophisticated approach within modern npk fertilizer production technology. This equipment works alongside other crucial machinery like the rotary drum granulator and roller press granulator production line to transform raw materials into premium fertilizers. The complete npk fertilizer production line integrates various processes from initial fertilizer compaction using specialized fertilizer compaction machine equipment to final screening through rotary screener systems. Similarly, organic fertilizer production utilizes equipment such as chain compost turning machine and windrow composting machine for the essential organic fertilizer fermentation process, followed by granulation through innovative new type two in one organic fertilizer granulator. The comprehensive npk manufacturing process and fermentation composting technology for organic fertilizer together form the backbone of modern fertilizer production machine systems. Whether through drum granulation in rotary granulator equipment or fertilizer granules compaction in advanced fertilizer compactor machines, these integrated production lines demonstrate remarkable efficiency in transforming diverse raw materials into uniform, high-quality fertilizers that meet agricultural needs worldwide.

Fertilizer granules compaction technology: Reshaping the form and efficacy of organic fertilizer

fertilizer granulator Nov 19, 2025

In agricultural production, the form of fertilizer often affects its effectiveness. Now, through advanced extrusion technology, fertilizer can be “reshaped” into uniform granules, a transformation that is quietly improving the efficiency and convenience of fertilization.

The core of extrusion technology lies in forcing pre-treated organic raw materials through a specific mold using mechanical force to form granules of uniform size and stable density. This process, seemingly simple, actually relies on the coordinated operation of the entire bio-organic fertilizer production line.

Before extrusion, the raw materials need to undergo sufficient fermentation and conditioning. Here, a windrow compost turning machine plays a crucial role. Its efficient turning method replaces traditional, heavy manual operations and is an important link in achieving large-scale pre-treatment.

When the fully fermented raw materials enter the subsequent stages, they reach the critical stage of extrusion molding. Modern bio-organic fertilizer equipment integrates multiple functions such as conveying, mixing, conditioning, and extrusion. By precisely controlling moisture and pressure, these devices can continuously produce granular products with moderate hardness and a smooth surface.

Finally, after drying and sieving, these granules are endowed with a longer shelf life, better slow-release properties, and a precise application experience. They are less prone to clumping, easier to spread mechanically, and allow nutrients to be released more stably into the soil.

From bulk materials to granules, fertilizer granules compaction technology represents more than just a change in form; it’s an upgrade to the organic fertilizer application experience.
