A granulation process wherein a liquid is sprayed into a prilling tower (1) by means of a rotating prilling bucket (15) having a perforated side wall (15a), and the liquid jets exiting said perforated side wall are subjected to a vibrating action according to the axial direction (A-A) of the prilling tower (1), while the remaining liquid mass inside the bucket is kept substantially free from said vibrating action. A suitable apparatus is also disclosed, wherein the peripheral side wall (15a) of the prilling bucket (15) is connected to vibration imparting means and has a flexible connection with the frame (15b, 15c) of the bucket.
