Get PriceGranulation is the process of forming grains or granules from a powdery or solid substance producing a granular material It is applied in several technological processes in the chemical and pharmaceutical industries Typically granulation involves agglomeration of fine particles into larger granules typically of size range between 0 2 and 4 0 mm depending on their subsequent use
Get PriceDry 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
