Weekly Topic on Compound Fertilizers (II): How to handle return materials of high-tower nitrate or urea-based compound fertilizers (with substandard nutrients)?

For the substandard nutrient-containing products generated during the production process of high-tower nitro or urea-based compound fertilizers, should they be sent back to the mixing tank for melting and re-granulation, or should some other method be used for their separate treatment?
These, as waste, are sent to the roller workshop along with other high-tower waste for utilization.
The substandard nutrient products generated during the production process of high-tower nitro or urea-based compound fertilizers should be directly returned to the mixing tank for melting and then re-granulated.
However, if products with substandard nutrients are directly returned to the mixing tank for melting and re-granulation, it will inevitably affect the composition of other materials in the mixing tank, which in turn may result in new products with substandard nutrients, creating a vicious cycle! Let’s discuss it together.
It is not possible to directly return to mixed granulation, as this will affect the final product
If it’s not possible to return directly to mixed granulation, then what should be done? Or rather, which device or process should be used for processing?
If there is a drum granulation device, it’s better to use a drum
What was said on the 2nd floor is correct – substandard materials are used in the roller workshop.
Friends upstairs: What should be done if there is only a high-tower setup and no drum granulation unit?
Just register another variety with a lower nutrient content; change the package. For example, if 20-4-21 is not up to standard, use the 20-4-20 package instead
