Date May 18, 1995A process for producing 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. |
