Features and Advantages of the NPK Fertilizer Production Line in Fertilizer Processing

The NPK fertilizer production line exhibits many significant features and advantages in fertilizer processing, with precise batching being one of its key highlights.

The line features a high-precision raw material metering system. Before production, a scientific formula is developed based on the varying nitrogen (N), phosphorus (P), and potassium (K) requirements of different crops at different growth stages. Subsequently, advanced electronic scales and flow controllers are used to precisely weigh the various nitrogen, phosphorus, and potassium-containing raw materials. Even trace amounts of additives can be added with pinpoint accuracy, minimizing errors.

Precise batching ensures a balanced supply of nutrients. Crop growth requires the synergistic effects of multiple nutrients, and the fertilizers produced by the NPK fertilizer production line perfectly meet this requirement. For example, during the seedling stage, an appropriate amount of nitrogen fertilizer promotes vigorous stem and leaf growth; during the flowering and fruiting stages, sufficient phosphorus and potassium promote flower bud differentiation and fruit enlargement. This precisely proportioned fertilizer acts like a nutrient package tailored to the crop, improving fertilizer utilization and avoiding waste caused by nutrient imbalances. In addition, precise mixing helps improve the quality of agricultural products. A reasonable nitrogen, phosphorus, and potassium ratio can enhance crop resistance to pests and diseases, reduce pesticide use, and improve fruit color, flavor, and sugar content, thereby enhancing the market competitiveness of agricultural products.

Furthermore, precisely mixed npk fertilizer production lines offer significant flexibility, allowing for rapid adjustment of formulations based on regional soil fertility and crop characteristics. Suitable fertilizers can be produced for acidic and alkaline soils, grain crops, cash crops, and horticultural crops.

Precise mixing also plays a positive role in environmental protection, reducing soil compaction and eutrophication caused by excessive fertilizer nutrients. The precise mixing of fertilizers produced by NPK compound fertilizer production lines, with its scientific and efficient formulations, has injected strong momentum into the sustainable development of modern agriculture.

Controlling the rotary drum granulator to improve the particle roundness

The time and frequency of material rolling in the rotary drum granulator are the primary factors to determine the pelletizing rate and particle roundness. The roundness of granular product in fertilizer production line can be improved by controlling the drum granulator.

Production principle of rotary drum granulator

Materials rely on surface tension, proper amount of liquid phase, extrusion force generated by rolling between materials, and correct movement direction of materials in the granulator, with small particles as the core, they absorb and adhere to each other and form balls in rolling. In a certain period of time, the higher the rolling frequency is, the higher the spheroidization rate is, and the rounder the particles are.

In the process of production, we have encountered two kinds of situations due to the different friction between materials and the wall of granulator.
1. The internal surface finish of granulator is large, so that the friction force between material and cylinder wall is reduced, and the upward movement force of material is weakened. If the material does not roll, it will not produce particles. In view of this situation, we can solve this problem by adjusting the speed of the granulator and installing a small plate inside.
2. The material in the drum granulator is severely stuck to the wall, and the friction between the material in the granulator and the wall of the barrel is increased, which raises the material in the machine too high, causing the material to fall from the top, so that the formed particles are not Rounding and excessive large particles, we think there are two reasons for this situation: on the one hand, the material is caused by too much viscous material, in this case, we change the formula of the npk production line to reduce the amount of viscous material; on the other hand , The inside of the granulator is not smooth. In this case, we change the internal material to increase the smoothness of the granulator.

On the other hand, we should also control the reasonable amount of material returned to the whole fertilizer production line. The process of rotary drum steam granulation is different from that of general fertilizer granulator, the relative pelletizing rate is lower, and the amount of returned material is higher. The amount of returned material directly affects the output and quality. The product has less particles, more powder and larger amount of return material, which directly affects the output. Large particles return more materials, directly affect the smoothness and roundness of the product.

Points for attention in roller extrusion granulation

Roller press granulator uses physical method to granulation. The whole process has no pollution and no waste. It is a very environment-friendly organic fertilizer machine. The following will lead you to understand the use of double roller extrusion granulator precautions.

Working principle of double roller press granulator

When the roller extrusion pelletizer is working, it is forced to roll the material into shape by two opposite moving roller skins of the granulation machine. Semi circular spherical cavities are regularly distributed on the two cylindrical roller skins. When the roller skin rotates against each other, the two semicircular cavities just form a complete spherical mold, and the materials inside are forced to be extruded into spherical particles. Due to the continuity of extrusion production, the particles and particles are connected together when they are just extruded, forming a cloth full of particles, which needs to be broken up by the crushing roller and divided into small round particles, and then screened from the screen to select the qualified particles.

The use of roller press granulator

When the double roller extrusion pelletizer is producing granular fertilizers, it should be noted that the ball sockets on the two roller skins should be properly positioned. If they are not adjusted in place, they will be misaligned during granulation and cannot produce qualified products. Granular fertilizer. In addition, after the particles are formed, they are released from the ball socket of the roller skin in time, so that uninterrupted production can be realized. If the formed particles are not released in time, complete particles will not be formed, which will affect the npk production line.
