Two major requirements are placed on fertilisers: On the one hand, the agricultural industry wants to obtain an end product in which the highest possible yields can be achieved with the lowest possible material input. This is all the more important when the required capacities are very high. On the other hand, environmental protection and sustainability are increasingly in focus. Fertilisers should be used as little as possible to relieve groundwater and maintain soil quality. Compaction and the subsequent production of granulate opens up new application possibilities for the agricultural industry.
If the fertiliser is in powder form, further processing and application to the field are more difficult. The solution here is to compact the fertiliser and then produce granules. The consistency of the end product plays an important role here. High compaction and minimum hardness are crucial so that the product does not fall apart. At the same time, it must not be overcompressed so that it is suitable for possible further processing (e.g. grinding). Furthermore, the end product must not show any cracks and must be able to dissolve correctly in the soil in order to maintain the soil quality.
The production capacity of Hosokawa systems is up to 15 t/h, depending on formulation adaptations of the product to the specific end application.
