  • The role of granulation in a changing pharmaceutical landscape

    Jan 11, 2019· Dry granulation can be achieved in two ways: slugging, in which a large compact is formed and then broken down into granules using a mill; or roller compaction, when material is compressed into a ribbon prior to the production of granules. Dry granulation is required when wet granulation may be unsuitable as a manufacturing method.
