Melt granulation, which is a simpler method, had the least influence of humidity on the physical properties of aspirin tablets, however, there was a change in disintegration time and friability after storage. Aspirin is easily hydrolyzed by water and it is therefore produced by slugging, which is a time consuming process. This work was aimed at studying the …
Dry granulation using Sluggers, Roller compactors. How to determine end point of granulation and problems in granulation process. Ankur Choudhary Jun 3, …
Slugging and roller compaction are two dry granulation techniques used widely in the pharmaceutical industry 8,10,16-19. Slugging was the favorite dry granulation technique in the 1950–1970s in the pharmaceutical industry 17. In this process, the primary powders are compressed into large tablets or slugs, followed by milling and sieving.

Introduction. Roll compaction/dry granulation (RCDG) is an agglomeration process, which has been known since the end of the 19th century. It is widely used in many industries. Although, RCDG has been used in the pharmaceutical industry since more than 50 years, it has recently drawn increasing attention [1].
Chopper. To ensure an optimum granular structure, the VG is equip-ped with a chopper with straight blades. The position of the. chopper in the lower third of the working vessel …
However, granulation is a more time-consuming technique compared with direct compression and there is also a risk of product cross-contamination and product loss during the different processing steps (granulation, drying, sieving). All of these factors can increase costs compared with direct compression. Dry granulation is more flexible than ...

If such a process is performed without adding liquids, this is called dry granulation. By Gerteis Maschinen + Processengineering AG Get more pharma manufacturing insight …
Typically, dry granulation can be done in two ways: either by roller compaction or by slugging. Dry granulation by roller compaction. Roller compaction is a widely used dry granulation method. This method compacts dry powders into a solid mass known as a ribbon. The ribbon is then broken up into the intended sizes using a milling …
A Comparison of Granulation Technologies. Granulation is one of the most important unit operations in the production of pharmaceutical oral dosage forms. However, there are many different technologies to choose from, each of which has different strengths and weaknesses. Many companies choose which one to use simply based on their own …
Granulation Method and Process Monitoring Matter. Published on: September 24, 2013. Cynthia A. Challener. The characteristics of tableted solid dosage drugs often depend on the granulation process, so selecting the most appropriate granulation technique and monitoring the process are crucial. Granulation is a key …

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 10-15 mm thick. A hammer mill is ideal for breaking up the slugs to create ...
Granulation is the process employed in the pharmaceutical industry whereby powder forms are made to bind together to form larger multiparticle entities or granules. Bonds between the primary particles are formed by compression, or by using a binding agent. Granulation is carried out for several reasons. It helps prevent the separation or ...
Double roller extrusion granulator. Product Introduction. The roller extrusion granulator is the key equipment of compound fertilizer granulation and has the characteristics of advanced technology, reasonable design, compact structure, novelty and utility and low energy consumption; it is equipped with corresponding equipment, which can form a ...
(Slugging of rollercompaction) Advantages: * Eliminates exposure to moisture and drying. * Dusty procedure. This is also called double compression or slugging method, this is valuable alternative to direct compression, where the dose of drug is too high or to wet granulation when the drug is sensitive to heat, moisture or both.

There are two dry granulation methods; slugging and roller compaction. In high-shear wet granulation process variability affects drug product quality. For example, inadequate impeller speed leads to inadequate granule growth [11,12,13]. Inadequate granule growth leads to unwanted granular porosity and strength, which in turn affects the …
Although granules used in the pharmaceutical industry have particle size in the range of 0.2-4.0 mm, they are primarily produced as an intermediary with a size range …
A: Firstly, dry granulation using roller compaction technology is a continuous process if using integrated technology — which differs to that for wet granulation. Following compaction, the resulting ribbons are then milled immediately, using a screen with a set mesh size to limit the upper particle size.
