The application of double roller press granulator in organic fertilizer production line can bring significant social benefits, mainly reflected in the following aspects:

1. Resource recycling: the double roller press granulator can convert agricultural waste, industrial dust and other materials into organic fertilizer particles, realizing the resource utilization of waste and reducing environmental pollution.

2. Improve the quality of fertilizer: Through the extrusion granulation process, the particles of organic fertilizer are uniform and high density, which is conducive to improving the application effect of fertilizer and crop absorption rate.

3. Energy saving and consumption reduction: The double roller press granulator has low energy consumption in the production process, without additional drying process, reducing production costs.

4. Environmental protection: Because the production process does not need to add wetting agents, it reduces environmental pollution and reduces greenhouse gas emissions.

5. Improve agricultural production efficiency: The use of organic fertilizers helps to improve soil fertility and crop yield, thereby improving agricultural production efficiency.

6. Promote the development of ecological agriculture: The use of organic fertilizers helps to promote the development of ecological agriculture and achieve sustainable development of agriculture.

7. Economic benefits: The production and use of organic fertilizers can bring economic benefits to farmers and enterprises and improve the market competitiveness of agricultural products.

8. Technological progress: The technological progress of double roller press granulator has promoted the technological upgrading and product innovation of the organic fertilizer industry.

Through these social benefits, the double roller press granulator not only improves the efficiency and quality of agricultural production, but also helps realize the resource utilization of agricultural waste and environmental protection.
