To ensure the quality of granules produced by organic fertilizer granulators, efforts should be made from multiple aspects such as equipment maintenance, process optimization, raw material processing, parameter adjustment and quality monitoring. The following are specific measures:

1. Equipment maintenance and inspection: After the end of each production day, conduct a thorough cleaning of the granulator to remove any residual materials on the surface and inside the organic fertilizer equipment. Regularly inspect the key components of the granulator, such as the pressure roller, ring die, cutter, screen, etc. Regularly add lubricating oil to the components that need lubrication, such as the pressure roller, to ensure their normal operation.

2. Raw material pretreatment: According to the requirements of the granulator, high-moisture materials are dried to control the moisture content within an appropriate range. For larger particle materials such as crop straw and branches, they need to be crushed to meet the feeding requirements of the granulator in terms of particle size.

3. Process optimization: Based on the production requirements of the organic fertilizer production line and the characteristics of raw materials, select an appropriate granulation process. For materials that require quenching and tempering, such as processes involving the addition of binders or steam, the quenching and tempering parameters must be strictly controlled.

4. Parameter Adjustment: During the production process, operators should closely monitor the operating status of the equipment and the quality of the products. According to the characteristics of the materials and production requirements, they should adjust the various parameters of the granulator in real time.

5. Quality Control: During the production process, the finished particles are regularly inspected, including indicators such as particle size, shape, strength, and moisture content. Ensure that the particle size deviation of the particles is extremely small, the compressive strength is high, and they are not easy to break during storage and transportation. Based on the test results, promptly feed back to the operators and adjust the equipment parameters or processes to ensure the stability and consistency of product quality.
