| 主权项 | 1. A process of granulation of a liquid phase, the process comprising generating a polydispersed flow of droplets of said liquid phase, with a descending motion in contact with solidification air along a substantially vertical granulation path, wherein inside said polydispersed flow, small-sized droplets solidify producing solid particles, and said solid particles grow by collision with other droplets of liquid; and wherein the liquid phase comprises urea or is represented by a urea solution. | ||
