fertilizer granulator Sep 10, 2025

In modern agricultural production, the NPK fertilizer production line plays a vital role in ensuring global food security through its precise design and efficient operation. This complete NPK manufacturing process transforms raw materials into nutritionally balanced fertilizer pellets, with each step showcasing the brilliance of modern engineering.

The entire NPK production process begins with precise ingredient proportioning. Raw materials such as urea, phosphate, and potash are accurately measured before being fed into crushers to achieve the ideal particle size for mixing. Subsequently, double-shaft paddle mixers or V-type mixers thoroughly blend these materials, laying a solid foundation for the subsequent granulation process.

Granulation represents the core of the NPK fertilizer manufacturing process. After adding appropriate moisture to achieve optimal humidity, disc granulators, drum granulators, or extrusion granulators transform the mixed materials into uniform pellets. These machines utilize rotational or pressure forces to create consistently sized, high-quality particles.

In the complete npk production line, the subsequent drying and cooling stages are equally crucial to the npk fertilizer production process. Fluidized bed dryers or rotary drum dryers effectively remove moisture from the pellets, while cooling drums reduce the temperature to suitable levels, ensuring product stability. Screening equipment further refines the selection of qualified particles, guaranteeing consistent product size and completing the transformation into high-quality NPK fertilizer.

To enhance fertilizer performance, some production lines additionally employ coating processes that create a protective film on the pellet surface, improving moisture resistance and controlling nutrient release rates. Finally, automatic packaging machines complete precise weighing and packaging, while advanced PLC control systems monitor the entire process to ensure every step is executed flawlessly.

This intelligent production line not only improves fertilizer quality but also promotes sustainable agricultural development, providing solid support for global food security.

How to Solve Dust Pollution in Organic Fertilizer and NPK Fertilizer Production

Because of the characteristics of materials, a lot of dust will be produced in fertilizer production, which will pollute the environment. In order to avoid this problem, dust removal devices should be set up in the design of organic fertilizer manufacturing process and NPK fertilizer production project to solve the problem of dust emission.

Dust Problem in Organic Fertilizer Production Line

In the organic fertilizer production line, when the moisture content of raw materials is low, they are often crushed and uneven solids. When the raw materials are transported to the equipment, if they are transported in the open air, there is no effective sealing measures, so the dust concentration in the air of the organic fertilizer manufacturing site will be too high. In addition, most small and medium-sized enterprises lack effective treatment means when discharging exhaust gas, which leads to the emission of exhaust gas not up to the standard and dust pollution.

Dust Problem in NPK Fertilizer Production Process

Take NPK fertilizer production project as an example, because the raw material of NPK fertilizer is brittle, it is easy to form small particle dust. When the dust is disturbed by airflow, it is easy to fly. Because of the low water content of NPK fertilizer, the dust is easy to absorb and adhere to the equipment. Therefore, when grading by using the screening device, the dust can easily block the sieve holes of the screen, thereby affecting the grading effect and even damaging the screen. As a result, the screen must be frequently replaced, on the one hand, the production cost is increased, on the one hand, to improve production costs, on the other hand to reduce production efficiency.

To solve the problem of dust pollution in the fertilizer manufacturing process, it is necessary to set up a dust collector room and dust collector equipment in the process of fertilizer production. Tianci Fertilizer Machine Manufacturer have designed a special cyclone dust collector to remove dust from the organic fertilizer manufacturing process. And in the construction of fertilizer plant, dust collector room is more suitable for large NPK fertilizer production line, we can help customers build dust collector room.

How to Preventing Caking from the NPK Fertilizer Production Process

NPK compound fertilizer is prone to cake because of its strength, moisture content, storage and so on. This article will introduce how to prevent caking from the process operation of NPK fertilizer production process.

NPK fertilizer production equipment produce products with smooth and uniform particles

Non-uniform particles, too many fine particles, non-smooth fertilizer, the compressive resistance, wear resistance is also poor, easy to be compressed and deformed in storage and transportation. The contact area between particles increase, which is easy to agglomerate. In order to produce products with uniform and smooth particle size, appropriate fertilizer granulator machine should be selected. Disc granulator and rotary drum granulator can produce moderate size particles and meet the requirements. If there is a higher requirement for the shape of the particles, it can also be combined with the ball shaping machine to polish the particles to ensure that the shape is qualified.

Strengthening the control of screening machine

In order to ensure the consistency of particle size and reduce the caking of powder, the product needs to be screened. According to the particle size of the product, different screens can be selected, and secondary screening can be selected in the process. Pay attention to the material screening in production, timely clean the screen.

Dryer reduces product water content

NPK compound fertilizer has a high water content, which will lead to salt reaction and cause hardening. The higher the water content, the easier the particles to agglomerate. Therefore, the NPK compound fertilizer production line must use a dryer to reduce the moisture content to the allowable range.

After the particle is dried by the dryer, the temperature is higher and the hygroscopicity effect will appear, so it needs to be cooled. The cooler reduces the material temperature to room temperature, and the product can be saved.

Coating treatment is used in NPK fertilizer production process

Choose the suitable material and use the coating machine to coat the particles. At the same time, pay attention to the amount of wrapping agent added. The amount of wrapping agent added is small, the particles are not wrapped completely, the effect is poor; the amount of adding is large, the wrapping oil will infiltrate into the inside of the NPK fertilizer, and the product is easy to cake.
