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.
The latest development of dry granulation can be achieved by rolling or slug granulation. These two different types are shown in Figure 1. Compared with wet granulation, dry granulation technology has not made great progress except for an important innovation of dry granulation technology known as roller compaction.

This chapter provides an indepth review of the relevant literature as well as a practical guide to completing the drug product design and commercialization via dry granulation. It presents an overview of the process components, material considerations and testing, and a stepwise look at the equipment, processes, and scaleup techniques.
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 ...

The dry granulation tablet manufacturing process eliminates several manufacturing steps but still requires weighing, mixing, slugging, dry screening, lubrication, and granule compression. Here are the steps for a successful dry granulation tablet manufacturing process: Weigh and mill formulation ingredients like drug substances and excipients.

The two procedures consist of: Process of slugging during dry granulation Dry granulation via roller compaction what, then, is the primary distinction between these two dry granulation principles? Let's investigate: ... To reduce attrition, use a ball mill. You require impact force. Mill, hammer, and screen; In other words, it depends on the ...
Dry granulation is the process of forming particles—, granulates or granules—from dry powder or powder blend without adding liquid to aid in the process. It serves as an established manufacturing process in the chemical, life science, and pharmaceutical industries, playing a key role in preparing powdered material for further processing ...

Definition of Dry Granulation In a study that was published on the National Center for Biotechnology Information, Srinivasan Shanmugam defines dry granulation as: It is a process that uses either compaction or mechanical compression to agglomerate dry powder particles. But, what is agglomeration?
Slugging. 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 1015 mm thick. A hammer mill is ideal for breaking up the slugs to create ...
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.
Dry granulation can be conducted in a tablet press using slugging tooling or in a roller compactor commonly. ... the compact (typically 25mm in diameter by about 1015mm thick) produced in the process is called a 'slug'. A hammer mill is suitable for breaking compacts. Roller compactor
Hammer mill for milling grain. A hammer mill is a mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of small machines have numerous industrial applications, including: Ethanol plants (grains); A farm machine, which mills grain into coarse flour to be fed to livestock; Fluff pulp defiberizing; Fruit juice production
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.
