Precise nutrient proportioning: Adopting a precise metering system to ensure that the proportion error of nitrogen, phosphorus, potassium and medium and trace elements is ≤ 1%, meeting the customized nutritional needs of different crops and avoiding crop growth problems caused by nutrient imbalance.

Wide raw material adaptability: It can be compatible with various solid raw materials such as urea, monoammonium phosphate, potassium chloride and liquid auxiliary materials, and can produce stably without complex pretreatment, reducing raw material procurement restrictions.

Outstanding production efficiency: Adopting continuous granulation process, the hourly capacity of a single production line can reach 1 - 10 tons, with a particle forming rate ≥ 90%, far exceeding the production efficiency of traditional mixed fertilizers.

Excellent particle quality: The finished particles have high roundness, compressive strength ≥ 20N, are not easy to agglomerate and break, and are convenient for storage and transportation. They also have good water solubility and slow - release performance, with the fertilizer effect duration extended by more than 30%.

Comprehensive cost optimization: Integrated production reduces losses in intermediate links, energy consumption is 15 - 20% lower than traditional processes, and at the same time, coating technology reduces fertilizer loss, indirectly reducing agricultural fertilization costs.

Multi - element collaborative granulation technology: Adopting drum granulation or spray granulation process to realize uniform fusion of solid and liquid raw materials, ensuring consistent nutrient distribution inside and outside the particles and avoiding excessive local nutrients.

Intelligent closed - loop control system: Equipped with a PLC automatic control system, it real - time monitors parameters such as granulation temperature (60 - 80℃), material humidity (30 - 40%), particle size (2 - 4mm), and automatically feedbacks and adjusts to ensure product stability.

Low - temperature and high - efficiency drying: Using a counter - flow dryer to complete drying at a low temperature of 60 - 70℃, avoiding nutrient volatilization caused by high temperature (nitrogen loss rate ≤ 3%) and retaining effective components of fertilizers.

Multifunctional coating system: Optional organic coating or inorganic coating device. By spraying slow - release agents or anti - caking agents, the moisture resistance and slow - release effect of fertilizers are improved, and the coating uniformity is ≥ 95%.

Modular combination design: The equipment can be flexibly combined according to the production capacity requirement (1 - 10 tons/hour), supporting later production capacity upgrading. The key components are made of wear - resistant materials, and the service life is extended to more than 5 years.
