Keywords: Roller compaction, Ribbon splitting, Sticking 1. Introduction Roller compaction is a pressure mediated dry granulation process by which materials are agglomerated without a liquid binder. A powder is fed between two counterrotating rollers by gravity from either a hopper or a screw feeder.

Real Time Ribbon Density Prediction Ribbon density (or solid fraction) is one of the critical quality parameters of roller compaction process that influences the compactibility of granules during tablet formation. We now offer a method of calculating the ribbon density in real time for both RD and production processes.

Roller compaction is the main technique employed in dry granulation. Ribbon sticking and splitting are among the major factors that can hinder the use of this process for some formulations. Ribbon splitting can occur either transversally (through the ribbon thickness) or longitudinally (through the ribbon width).

It was observed that transverse splitting is commonly associated with sticking of the split ribbons to the rollers and results in an inferior performance of the process, while longitudinal splitting is associated with an across‐width distribution of the ribbon density and increases with increasing values of the index. NA; Roller compaction is the main technique employed in dry granulation.

Roller compaction is a continuous dry granulation process for producing free flowing granules in order to increase the bulk density and uniformity of pharmaceutical formulations. It is a complied process due to the diversity of powder blends and processing parameters involved. The properties of the produced ribbon are dominated by a number of factors, such as the powder properties, friction ...

Previous research has shown that roller compacted ribbons have a three dimensional density distribution which can affect the particle size distribution of granules after milling. Our specific interest is in understanding and monitoring the density distribution of ribbons produced by roller compaction with near infrared spectroscopy.

Roller compaction has become very important in recent years. It produces stable granules by continuously compressing powders between two counterrotating rollers. The agglomerates, also called flakes or ribbons, are then comminuted via a downstream comminution unit into wellflowing and easytodose granules.

Roller Compaction. A GERTEIS® Roller compactor generally consists of three major units: A feeding system, which conveys the powder to the compaction area between the rollers. A compaction unit, where the powder is compacted between two counter rotating rolls by applying a force, to form ribbons .

Trails made with roller compacted flakes: • At the same roller compaction conditions, increasing the roll speed resulted in a finer granulate. (Fig. 3) • Changing the granulator speed from 60/40rpm CW/CCW to 150/120rpm did not have any influence. • Increasing the rotating angle of .

Roller compactors apply counterrotating rollers to agglomerate dry powder, normally a mix of powders, into sheets or sticks.. Let's look at the working principle of roller compactor for dry granulation. 1. Weighing of the Raw Materials. Before commencing the roll compaction process, you should have all the ingredients you require for the granulation process ready.

Roller Compacted Concrete is a mixture of cement, aggregates, and low water content mixed in a continuous mix pug mill. Cost savings in using RCC are achieved from faster production rates, no reinforcing steel used, and reduced labor costs. The end product is .

Roller compaction is a compaction process that employs the use of three key components: The feeding system: carries the raw material from the mouth of the machine to the compacting unit. The compaction unit: uses two counterrotating rolls to compact the material. The size reduction unit: mills the compacted material to the desired particle size.
