Understanding The Dry Granulation Process

The original method of dry granulation employed a heavy duty tablet press to compact the dry powder. The compacting process in this case is known as slugging and the compacted material was therefore in the form of "slugs" - typically 25 mm in diameter and 10-15 mm thick. A hammer mill is ideal for breaking up the slugs to create granules. A manufacturing company may also use a conventional ...
