ABSTRACT OF THE DISCLOSURE A device is described for the production of granules from two-phase mixtures. The initial product is enriched with crystal seeds in a pre-crystallizer whose temperature is controlled. The precrystallized mass is eventually fully crystallized on a cooling conveyor or the like. According to the invention, a droplet former (2) follows the pre-crystallizer (1). The droplet former consists of two tubular bodies (2a,2b) placed against each other with their walls. The exterior body (2a) is provided with a plurality of orifices (2d). The inner body is provided only with a coaxial row of orifices (2c). The droplet former (2) is arranged above the cooling conveyor (3) so that the coaxial row of orifices (2c) faces the conveyor, the orifices (2c) being aligned with the orifices (2d) during the rotation of the outer tubular body (2a). The advance in the art is in that the invention avoids the need for additional grinding process and simplifies the process of formation of granules of an improved quality.
