The advantages of the Dry Granulation method. Improved powder flow as the ideal particle size distribution can be attained by adjusting the compaction and milling process. With a better granular mix, material flows more easily, which means that conveying and feeding into downstream processes become troublefree, as caking and bridging are ...

Introduction. Granulation, a technique of particle enlargement by agglomeration, is one of the most significant unit operations in the production of pharmaceutical dosage forms, mostly tablets and capsules. 1 During the granulation process, small fine or coarse particles are converted into large agglomerates called granules. Generally, granulation commences after initial dry mixing of the ...

In contrast, dry granulation is the formation of granules without using any liquid solution. Dry granulation can be accomplished with two methods, slugging and roller compaction, and it is used above all for those tablet ingredients that are sensitive to moisture or are unable to withstand elevated temperatures.

The two most common for dry granulation operations are slugging and roller compaction. Slugging is a compaction process that uses a tablet press. The pharmaceutical products produced through this method often are varied in weight and density, resulting in lower product and production quality.

Compared to wet granulation, DG is a shorter, more costeffective manufacturing process. As outlined in Figure 1, DG can be performed in two ways slugging or roller compaction. With slugging, tableting presses are used to form large tablets (slugs) which are then broken by a hammer mill to form granules.

The process of dry granulation is also called double compression or precompression. The size enlargement process associated with dry granulation can greatly enhance the compression of the powders. Unless dry granulation is carried out, these granules cannot be compressed at all. The powder particles are exposed to a process of compacting so ...
