Abstract
The present invention relates to a process for the preparation of granules comprising the steps of: providing a granulation zone comprising particles, the particles being kept in motion; providing a first feed stream comprising a liquid composition into the granulation zone, the liquid composition being applied onto or over the moving particles in the granulation zone; withdrawing a product stream comprising granules from the granulation zone, the granules being the result of layered growth of the moving particles in the granulation zone; wherein a second feed stream comprising granulation nuclei is fed into the granulation zone, wherein the granulation nuclei have a particle size distribution characterized by a standard deviation of the particle size that is less than 15% of the mean particle size, and wherein the second feed stream comprises between 0.05 wt % and 50 wt % of the product stream.
