Abstract

a. On propose un procédé pour la fabrication d'engrais potassique granulé n'émettant pas de poussière et résistant à l'abrasion. b. On soumet l'engrais potassique en grains aux différentes étapes de la combinaison qui constitue le procédé et qui sont, dépoussiérage des grains de sels potassiques en lit fluidisé, mouillage avec 0,5 à 2 % d'eau, évaporation de la majeure partie du liquide et durcissement sous l'effet d'une recristallisation. c. Ce procédé permet d'obtenir des granulés qui supportent le transport et les manutentions sans émettre de poussière et sans se briser.
