FIELD: chemistry.
SUBSTANCE: device and method for granulation of the liquid phase, in which create polydisperse stream of droplets specified liquid phase with downward movement in contact with air for curing along is mostly vertical tract process granulation and where small droplets in the polydisperse thread of solidified, forming solid particles and these particles in a collision with other droplets of fluid increase in size; in some embodiments, of carrying out the invention product obtained by this new way of granulation, can be grown in the usual way.
EFFECT: invention allows you to turn urea melt in a solid product that has the optimal size and physical characteristics.
