Soil is a fundamental natural resource on which the entire life of the planet depends. Fertilizers are indispensable to replenish what has been taken away by harvesting agricultural products. In the subdivision of fertilizers, provided by the regulation, there are, among others 4 fundamental functional categories (PFC): Fertilizers (organic, organo-mineral, inorganic), calcium and/or magnesium remedies, soil conditioners and cultivation substrates. The fertilizers are very interesting as they are produced in the form of granules for the advantages they offer regarding their management from a technical, economic and environmental point of view as described in detail in the parts concerning grinding and granulation. This manuscript deals exclusively with solid and in particular granular products, highlighting the state of the art achieved by mills, mixers and granulators of the Eirich group. (Fig. 1). The level obtained is measured in terms of: ability to achieve the required fertilizer quality, reliability, minimum energy consumption, facility and speed of cleaning-maintenance, possibility to work different PFCs quickly switching from one type to another and working with the highest degree of automation.
