High concentration NPK fertilizers require extremely high nutrient content and uniformity, and their production line equipment configuration needs to meet these strict standards.
In the raw material processing stage, fine fertilizer crushers and screening equipment are used to ensure the purity and particle size of the raw materials. For difficult to process raw materials such as phosphate ore, professional grinding machines are used to grind them into extremely fine powders to improve the adequacy of subsequent reactions.
In the process of measuring ingredients, high-precision electronic weighing scales are key. It is not only necessary to accurately measure the dosage of nitrogen, phosphorus, and potassium as the main raw materials, but also to accurately weigh various trace elements. By using a computer control system, real-time monitoring and adjustment of ingredient ratios are carried out to ensure accurate nutrient concentration of fertilizers.
Select an efficient plow blade mixer for the mixing equipment. Its unique mixing structure can fully mix raw materials of different densities and particle sizes in a short period of time, ensuring uniform distribution of high concentration fertilizer components.

Granulation equipment usually uses a roller extrusion granulator. By using strong pressure to extrude the mixed materials into shape, high-density and high-strength granular fertilizers are produced, which is beneficial for maintaining the stability of high concentration nutrients in the particles.
The drying equipment adopts low-temperature drying technology to avoid the damage of high temperature to fertilizer nutrients. By using a belt dryer, the drying temperature and time can be precisely controlled, ensuring that the moisture content of the fertilizer meets the standard while maximizing the retention of nutrients.
The cooling equipment adopts a forced air cooling system to quickly cool fertilizer particles, improve their hardness and wear resistance, and prevent particles from breaking and deforming during subsequent processing.
The screening equipment uses high-precision flat rotary screens, which can accurately screen out high concentration fertilizer particles that meet the particle size requirements, and timely separate unqualified particles.
To further improve the stability and long-term effectiveness of fertilizers, specialized coating equipment will be equipped, using special coating materials to wrap fertilizer particles and delay nutrient release rate.
The packaging equipment adopts a sealed packaging form to prevent high concentration fertilizers from getting damp and deteriorating during storage and transportation. The automatic packaging scale ensures accurate weight of each bag of fertilizer, clear packaging labeling, and key information such as nutrient content of the fertilizer.
The equipment configuration of the high concentration NPK fertilizer production line is focused on ensuring the high concentration, uniformity, and stability of the fertilizer, and a series of advanced equipment is used to ensure the production of high-quality high concentration fertilizer products.
