Reducing the waste of resources in the fertilizer granulating produciton line can be started from the following aspects:

1. Optimize the production process: efficient granulation process can improve the efficiency of phosphate fertilizer granulation and reduce energy consumption. To sort out the production process, simplify unnecessary links, reduce energy waste.

2. Resource recycling: Through the multi-stage cycle screening method, reduce the finished organic fertilizer particles contained in the waste and reduce the waste generation rate.

3. Energy saving and emission reduction technology transformation: energy-saving drying equipment and new mixed organic fertilizer equipment are used to reduce production energy consumption. Using waste heat recovery technology, the waste heat in the production process is converted into usable energy.

4. Improve the energy efficiency of equipment: evaluate the energy efficiency of equipment used in the production process, identify inefficient equipment, and propose upgrade or replacement suggestions. Optimize the design of key equipment to improve its energy efficiency ratio and reduce energy consumption.

5. Intelligent control and automation: The application of intelligent control system to achieve automation and refinement of the production process and reduce energy consumption.

6. Reduce emissions of waste gas, wastewater and solid waste gas treatment: adopt efficient dust removal and deammonia technology to reduce dust and ammonia emissions. Construction of sewage treatment facilities to ensure effective treatment of wastewater in the production process. Collect and dispose of solid waste separately to ensure that it is not dumped and stacked arbitrarily.

Through the above measures, it can effectively reduce the waste of resources in the fertilizer granulation production line, improve production efficiency, reduce production costs, and reduce the impact on the environment.
