In order to produce a granulated material from a powder mixture containing at least two components, one of which is in crystal or crystalline form and at least one contains water of crystallization and/or is reactive, granulation is carried out in an inclined drum. Powder is fed in at one end and granulate removed at the other, after being transported inside the drum for a desired period while the drum is rocked in a way which largely eliminates shear forces. A quantity of liquid at least approximately equal to the quantity of water of crystallization present and sufficient for the formation of a superficially active solution adhesive is released inside the drum, where appropriate by partial reaction of the reactive component(s), after which the powder mixture components are granulated by surface adhesion.

Pour produire des granulés à partir d'un mélange pulvérulent comprenant au moins deux constituants dont un au moins figure sous forme cristalline ou de cristal et dont un au moins contient de l'eau de cristallisation et/ou est réactif, la granulation s'effectue dans un tambour (5) incliné par rapport à l'horizontale. La poudre est introduite à une extrémité et les granulés sont extraits à l'autre extrémité. Les granulés sont transportés de force à l'intérieur du tambour pendant un temps de séjour voulu, sous l'effet d'un mouvement de roulis tout en évitant l'apparition de forces de cisaillement. Un volume de liquide correspondant au moins approximativement au volume d'eau de cristallisation et suffisant pour former une colle en solution agissant en surface, est libéré à l'intérieur du tambour (5), éventuellement par une réaction partielle du(des) constituant(s) réactif(s). Les constituants du mélange pulvérulent sont ensuite granulés par adhérence en surface.
