Abstract
L'invention concerne un procédé de conditionnement d'engrais en granulés, par exemple d'engrais en granulés contenant du chlorure de potassium ou du sulfate de potassium ; on produit tout d'abord les granulés qui sont mouillés par exemple avec de l'eau puis on soumet les granulés mouillés à un flux d'air de façon à les compacter, et ce éventuellement par utilisation de la chaleur propre des granulés. De préférence, les granulés mouillés sont déshydratés avec une quantité d'air d'au moins 100 m3 par tonne de granulés à une température d'air inférieure à 45 °C.
