Process for the preparation of granules

摘要

Low-dust, storage-stable granules are obtained in a continuous operating process in which the powder to be granulated is granulated in succession in a high-speed and low-speed mixing granulator, with the addition of a granulating liquid, and is then dried in a fluidized bed into which a liquid containing a binder is sprayed. The process is particularly suitable for the preparation of dyestuff granules which can easily be dispersed in the use medium.
