<p>Process for the preparation of granules from a liquid composition by spraying the liquid composition in the granulation zone of a granulating device onto or over solid particles present in the granulation zone that are being kept in motion, as a result of which these particles grow, and withdrawing a stream of particles from the granulation zone, yielding a stream of particles of the desired size, with a part of the air flow leaving the granulating device during granulation being returned to the granulating device. In this way only a small part of the air flow needs to be purified of the starting materials.</p> |
