Abstract
Process and apparatus for granulation of a liquid phase, wherein a polydispersed flow of droplets of said liquid phase is generated, with descending motion in contact with solidification air along a substantially vertical granulation path, and wherein inside said polydispersed flow, small-sized droplets solidify producing solid particles, and said solid particles grow by collision with other droplets of liquid; in some embodiments the product obtained with this new granulation method can be grown with the conventional method.
