Detailed analysis of process flow of NPK fertilizer production line

The NPK compound fertilizer production line is a comprehensive and scientific compound fertilizer production flow line, which plays an extremely important role for the user’s own production demand, cost control and economic benefit improvement. Generally speaking, the NPK fertilizer production line mainly includes raw material distribution, mixing and agitation, material pulverization, granulation and discharge, primary classification, material drying, secondary grading, finished product coating and packing etc., through effective process control and material selection, Comprehensively grasping the required material targets, the production and use of compound fertilizers have achieved the desired results.

NPK fertilizer production line

Especially with the grasp, refinement and classification of the concept of ecological planting, green planting, resource utilization and recycling, the demand and demand level of the NPK compound fertilizer production line have been maximized. Moreover, as the technology continues to mature and continue to advance, the production processes of each branch are refined and subdivided. For example, for raw material ingredients, the industry generally adopts the ratio of urea, ammonium chloride, ammonium phosphate and ammonium nitrate, and is equipped according to a certain proportion, and also needs to have the conditions of the local soil itself. For example, there is also a great demand for material granulation. Before the material is fed into the fertilizer granulator machine for granulation, the material should be uniformly stirred, pulverized uniformly, and the overall shape is good, and this step is in the process of the NPK fertilizer production. It is a must and the most important part.


As a leading fertilizer machine manufacturer in China, we can produce different kinds of fertilizer granulator machine for the fertilizer manufacturing process, welcome to inquiry.

For the optimization, adjustment and upgrading of the NPK compound fertilizer production line, as well as the control and scientific management of the entire assembly line operation; it has played a positive role in saving manpower, reducing costs, long-term production and profit improvement.


50 Million Tons/year NPK Fertilizer Production Line

50 million tons/year npk fertilizer production line manufactured by Zhengzhou Tianci is a large scale NPK compound fertilizer production line. The whole annual output 50 million tons npk fertilizer production line has the high efficiency, easy operation and maintenance, which has been widely applied in breeding industry, planting industry and fertilizer manufacturing industry in many countries.

Here is the 3D video display of 50 million tons/year npk fertilizer production line in Zhengzhou Tianci:

The main equipment of 50 million tons/year npk fertilizer production line in Zhengzhou Tianci:
1.Batching System Series
2. Vertical Mixer
3. Rotary drum granulator
 4. Rotary Dryer
5. Other facilities
6. Rotary Cooler
7. Rotary Screener
8. Chain Crusher
9. Coating Machine
10. Automatic Fertilizer Packing Machine

The manufacturing process of 50 million tons/year npk fertilizer production line in Zhengzhou Tianci:
 It is mainly used for weighing, distributing, mixing, batching and feeding of 3-8 kinds of proportional single fertilizer materials. The machine has the advantages of simple operation, high material precision, adjustable material ratio, high efficiency, energy saving, easy installation.
 Vertical mixer is a kind of fertilizer mixer which is mainly used for mixing raw materials. The machine is made of polypropylene plate lining or stainless steel plate, which is not easy to stick and wear resistance. The cycloidal pinwheel reducer has the advantages of compact structure, convenient operation, uniform mixing and convenient unloading and conveying
 Rotary drum granulator is a molding machine that can make material into a particular shape. It is one of the key equipment of NPK Compound Fertilizer production line, which is  suitable for cold or hot granulation and mass production for high and low concentration compound fertilizer. The main mode of work is granulation with wet granulation.


 Fertilizer Drying Machine is mainly used to dry a certain temperature and granularity of fertilizer. On the other hand, it also can be used for drying other materials in compound fertilizer processing plant and organic fertilizer production plant. The Angle and distribution of Jan plate of this machine is designed reasonable, and it is reliable in performance. Ii has high thermal efficiency, uniform drying, cleaning fewer materials, convenient use and maintenance.
 The hot stove is mainly used for providing the heat source for the drying process, and the cyclone dust collector is used for reducing the dust in the production of fertilizer to protect environment. Belt conveyor is used to transport fertilizer materials in different production process.
 Use dryer together can greatly improve the cooling rate, reduce labor intensity and improve the quality, further remove moisture, reduce the grain temperature of fertilizer.
 It is the common equipment in the production of compound fertilizer, which is mainly used for the even classification of qualified fertilizer granules and unqualified fertilizer granules.
8. Chain Crusher
 The unqualified fertilizer granule enters into chain crusher, and it is grinded into the powder for the second granulation process.
9. Polishing Machine
 This machine is a new type of equipment: the granulating rate is more than 95%. The motor adopts flexible belt drive to start smooth, slow down the impact force and improve the service life of the equipment. Through the process, the discs are hard and durable, it is never deformed and sturdy base. It does not need foot bolt fixed. It also has the long service life and so on, it is deeply used. High praise of the household is the ideal product for the majority of users. it is not only used for 50 million Tons NPK Fertilizer Production line in Zhengzhou Tianci, but also can be used in the organic fertilizer production line.
 It is mainly used for automatic quantitative packaging of powder, granules and tons bags fertilizer.  Its high precision, automatic weighing controller, good reliability. Good integrity, small floor area, flexible and convenient installation. And the feeding mode of the powder feeding equipment is a spiral feeding, fast and slow feeding through the controller to achieve, feeding speed can be arbitrarily set.
