Abstract

A process for preparing granules is disclosed. The process comprises the steps of feeding the input material for granulation in a processor using one or more powder feeders, introducing steam as a granulation activating agent in the processor, granulating the input material in presence of the steam to form granules, and collecting the granules from a discharge zone of the processor. A co-rotating twin-screw processor for preparing granules is also disclosed.
