Process for producing granules

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..
