Modern fertilizer production is a highly systematic process involving a complete industrial chain from raw material processing to finished product packaging. Fertilizer production equipment can be divided into five key systems according to the technological process, each playing an indispensable role.

Raw Material Pretreatment System

Raw material pretreatment is the first process in fertilizer production. Crushers are responsible for breaking down bulk raw materials such as potash ore and straw to suitable particle sizes below 8 millimeters. Mixers uniformly blend raw materials including nitrogen, phosphorus, and potassium according to precise formulas, ensuring balanced nutrient distribution. Screening machines remove impurities through vibration screening and precision filtration, providing clean raw materials for subsequent processes.

Core Reaction and Fermentation System

Depending on the fertilizer type, core reaction equipment has distinct characteristics. Organic fertilizer production mainly relies on fermentation turners and maturation tanks, converting organic materials into stable humus through aerobic fermentation processes. Chemical fertilizer production uses equipment such as dissolution tanks, flotation machines, and crystallizers to achieve raw material purification and transformation. Chelation tanks effectively prevent precipitation of medium and trace elements, ensuring fertilizer quality.

Granulation and Forming System

Granulation is a core step in fertilizer production. Extrusion granulators form granules through high-pressure extrusion and are suitable for materials such as organic fertilizers and potassium chloride. Disc granulators utilize centrifugal force to precisely control particle size within the 2-4 mm range. Spray granulators produce water-soluble fertilizers through atomization and drying processes, while coating granulators can precisely control the coating of slow-release fertilizers. Drum granulators, with their large-scale production capacity, are the preferred equipment for NPK compound fertilizer production.

Post-treatment and Packaging System

After granulation, the fertilizer requires meticulous post-processing. A secondary screening machine ensures uniform particle size, while anti-caking equipment uses a special coating agent to prevent clumping during storage. Environmental protection equipment, including dust removal and wastewater treatment systems, ensures the production process meets environmental requirements. The final packaging process utilizes automated equipment for accurate metering and efficient packaging.

Modern fertilizer production lines achieve efficient and environmentally friendly large-scale production through the coordinated operation of various systems. Taking a typical NPK compound fertilizer production line as an example, the entire process from raw material pretreatment to finished product packaging can reach a daily output of 500 tons. The products fully comply with national quality standards, providing a reliable fertilizer guarantee for global agricultural production.

Industrial Organic Fertilizer Production Process

In modern agricultural production systems, industrial-scale organic fertilizer production has become a crucial link in achieving sustainable agricultural development. Through standardized processes and scientific quality control systems, organic waste is transformed into high-quality organic fertilizers, providing strong support for soil health and crop growth.

Raw Material Pretreatment: Foundation of Quality

Raw material pretreatment forms the foundation of the entire production process. First, strict sorting of materials like livestock manure and straw is required to remove impurities such as stones and plastics, ensuring material purity. Subsequently, raw materials are processed to appropriate particle sizes through crushing – livestock manure is crushed to below 10mm, while straw is cut to 2-5cm lengths. Most crucially, carbon-to-nitrogen ratio adjustment precisely controls the material’s C/N ratio within the ideal range of 25-30:1, while simultaneously adjusting moisture content to the optimal fermentation state of 55%-60%. The meticulous operations in this stage directly determine subsequent fermentation effectiveness and final product quality.

Fermentation and Maturation: Core of Transformation

Fermentation and maturation represent the core process of organic fertilizer production, typically employing trough-type aerobic fermentation technology. This process consists of three distinct stages: temperature rise phase, high-temperature phase, and cooling maturation phase. During the temperature rise phase, materials rapidly heat up to above 55°C with the action of fermentation agents; the high-temperature phase maintains temperatures between 55-65°C, effectively eliminating pathogens and weed seeds; the cooling maturation phase completes the final transformation of organic matter. The entire fermentation process requires precise control of temperature, humidity, and ventilation conditions to ensure complete decomposition of organic matter and effective release of nutrients.

The key to successful fermentation lies in microbial activity management. By regularly turning piles and providing ventilation and oxygen supply, optimal growth conditions are created for aerobic microorganisms, representing the technical core of efficient fermentation.

Post-Processing: Refinement and Enhancement

Matured materials enter the post-processing stage. Dehydration and drying come first, reducing moisture content to below 20% to meet national organic fertilizer standards. Subsequent crushing and screening processes ensure uniform product particle size. According to market demands, formula adjustments can be made, adding functional microbial agents to produce bio-organic fertilizers, or compounding with chemical fertilizers to produce organic-inorganic compound fertilizers. Each step requires strict quality testing to ensure final products fully meet standards for nutrient content, heavy metal indicators, and microbial indicators.

Packaging and Storage: Quality Assurance

Qualified organic fertilizer products are packaged using moisture-proof materials with clear product information and quality standards. Storage requires dry, ventilated environments to prevent product caking due to moisture.
