What is compound fertilizer equipment

Compound fertilizer equipment is a complete set of production equipment used to process multiple nutrients (nitrogen, phosphorus, potassium, etc.) into granular, powdery, or columnar compound fertilizers. The core is to achieve raw material mixing, granulation, shaping, and post-treatment to meet the nutritional needs of different crops.

Core definition and function of compound fertilizer equipment

Compound fertilizer equipment is not a single machine, but a production line composed of multiple devices. Its core function is to process single element fertilizers such as urea, monoammonium phosphate, potassium chloride, organic fertilizers, minerals and other raw materials into compound fertilizer products with uniform nutrients, easy application and storage through mixing, granulation, drying, screening and other processes.

The main components of compound fertilizer equipment (according to the process flow)

Raw material pretreatment equipment: crusher (crushing large raw materials), screening machine (screening uniform particle size), mixer (mixing multiple raw materials to ensure nutrient balance).
Core granulation equipment: Common ones include disc granulators, drum granulators, extrusion granulators, etc. (the disc granulator you previously focused on is one of them).
Post processing equipment: drying machine (to remove moisture from particles), cooling machine (to reduce particle temperature and increase hardness), grading screening machine (to separate qualified and unqualified particles, and to reprocess unqualified particles).
Auxiliary equipment: hoist (conveying materials), dust collector (processing dust, meeting environmental standards), packaging machine (quantitatively packaging finished products), control system (regulating temperature, speed and other parameters).

Common types of compound fertilizer equipment (divided by granulation process)

Disc granulation production line: simple equipment, low investment, suitable for small and medium-sized production, uniform particles.
Drum granulation production line: With large production capacity and high degree of automation, it is suitable for large-scale industrial production.
Extrusion granulation production line: no need to add water or a small amount of water, low energy consumption, suitable for high viscosity raw materials.

Core application scenarios of compound fertilizer equipment

The core application scenario of compound fertilizer equipment is the large-scale production of different types and specifications of compound fertilizers, covering agricultural production, industrial supporting, special field needs, etc. The specific classification according to application scenarios is as follows:
1、 Core scenarios of agricultural production (mainstream applications)
Production of specialized fertilizers for field crops: For bulk crops such as wheat, corn, rice, and cotton, complete sets of equipment are used to produce granular compound fertilizers with high nitrogen, high phosphorus, and potassium formulas to meet the nutrient requirements of large-scale planting.
Production of specialized fertilizers for economic crops: customized production of specialized compound fertilizers with trace elements (calcium, magnesium, sulfur, boron, etc.) for vegetables, fruits, flowers, tea and other crops, suitable for the refined fertilization needs of facility agriculture and greenhouse planting.
Production of characteristic crops and regionally adapted fertilizers: Combining soil characteristics of different regions (such as acidic soil and saline alkali soil) to produce improved compound fertilizers; Or create specialized formula fertilizers for characteristic crops such as potatoes, sugarcane, and tobacco, suitable for local agricultural industrial belts.
2、 Industrial and large-scale production scenarios
Large scale production of fertilizer enterprises: Large chemical and fertilizer groups adopt fully automated complete sets of equipment (such as drum granulation production lines) to achieve continuous production of compound fertilizers with an annual output of 100000 to 500000 tons, meeting the supply needs of national or regional markets.
Flexible production of small and medium-sized fertilizer factories: Small and medium-sized enterprises use modular equipment (such as disc granulation production lines), with an annual output of 100000-100000 tons, suitable for local agricultural needs, and can quickly switch formulas to produce elemental compound fertilizers, compound fertilizers, etc.
Integrated production of organic fertilizer and compound fertilizer: In response to the demand for “organic fertilizer+chemical fertilizer” mixed formula fertilizer, the equipment is compatible with organic fertilizer raw materials such as livestock manure and straw, as well as chemical raw materials, to produce bio organic fertilizer and organic-inorganic compound fertilizer.
3、 Special fields and customized scenarios
Production of slow-release fertilizers: Equipped with specialized equipment such as coating and slow-release agent addition, we produce slow-release compound fertilizers with a controlled release period of 3-12 months, which are applied in long-term maintenance scenarios such as landscaping, golf courses, and seedling cultivation.
Functional compound fertilizer production: By modifying equipment and adding components such as humic acid, amino acids, and biological agents, functional compound fertilizers that are resistant to stress, promote root growth, and improve soil are produced to meet the needs of ecological and green agriculture.
Customized production for export orders: Targeting the climate and crop needs of emerging agricultural countries such as Southeast Asia and Africa, customized production of compound fertilizers that meet local standards is carried out through complete sets of equipment to support export trade.
4、 Supporting and extended application scenarios
Technical upgrading of fertilizer processing enterprises: providing equipment updates and production line renovation services for old fertilizer factories, improving production capacity, reducing energy consumption, and meeting environmental protection and intelligent production requirements.
Supporting agricultural industrialization projects: In modern agricultural industrial parks, agricultural science and technology parks, and other projects, supporting construction of compound fertilizer production workshops is carried out to achieve a localized closed-loop of “raw materials processing application”.
