The rapid development of fertilizer granulating production line is of great significance to the agriculture and fertilizer industry, and its necessity is mainly reflected in the following aspects:

1. Improve fertilizer utilization rate: Through the granulation process, the particle size, uniformity and release rate of fertilizer are optimized, thereby improving the utilization rate of fertilizer and the absorption efficiency of crops.

2. Promote the green development of agriculture: granulation technology can help reduce the environmental pollution caused by excessive use of fertilizer, and promote the transformation of agriculture to the direction of green and environmental protection.

3. Improve the quality of fertilizer products: the granulation production line can ensure the consistency and quality of fertilizer particles and improve the market competitiveness of products.

4. Promote technological innovation: The technological progress of organic fertilizer granulators, such as the application of smart sensors and Internet of Things technology, has promoted the innovation and development of fertilizer production technology.

5. Promote sustainable development of agriculture: granulation production line helps to realize resource utilization of agricultural waste, reduce the use of fertilizer, reduce the impact of agricultural production on the environment, and promote sustainable development of agriculture.

6. Improve economic efficiency: By improving fertilizer utilization efficiency and crop yield, granulation production lines help to increase farmers' income and enhance agricultural economic efficiency.

In summary, the rapid development of fertilizer granulation production lines plays an important role in improving fertilizer efficiency, protecting the environment, improving agricultural competitiveness and achieving sustainable development.
