Mechanistic study of the effect of roller compaction and lubricant

Both compact hardness and tensile strength drop dramatically when microcrystalline cellulose is roller compacted to higher SF of 0.64 or 0.84. When the microcrystalline cellulose is roller compacted, it undergoes volume reduction as the ribbon is compressed and pressure must be increased to form ribbons with a higher SF.

Which Roller Compactor Best Fulfills Your Process Needs

This System enables the best compression or tamping of the powder, and inherent deaeration of the feed powders so that the cantilevered rolls can produce a consistent compacted ribbon. Both IR and CCS-Series models utilize the world-class FitzMill ™ to mill and granulate the ribbon. Process flexibility is maximized by Fitzpatrick’s unique ...

Pre-blend, ribbon, and final blend characterization. Prior to roller compaction, the true density of the pre-blend was determined using an Accupyc II 1340 pyc-nometer (Micromeritics, Norcross, GA). During roller compaction, the apparent density (envelope density) of the compacted ribbons was determined using a GeoPyc 1360 pycnometer ...

Effect of roll-compaction and milling conditions on granules

non-compacted powder, but also confers certain properties to the ribbons such as density distribution across the ribbon width [17–19]. After being compacted, the ribbons are subsequently milled into granules. Regarding the milling step, many variables, such as mill type, mill design, screen size, speed and mode of oscillation,

Performing significant small scale milling trials for roller

Beside material/formulation, also roller compaction process parameters can affect the PSD of the granulate. A ranking of the influencing process parameter for roller compaction is given in Fig. 2 [2]. The most important parameter is the ribbon density, which is a result of the specific roll force and gap used in the roller compactor.

3.1.2 Non-continuous ribbon mixers. Non-continuous or interrupted ribbons are similar to the continuous ribbon mixers except that short sections called "paddles" or "ploughs" are spaced in a spiral round the mixer shaft. Action is different from that of continuous ribbon mixers, and may be more satisfactory for mixing liquids with dry solids.

On-Line Monitoring of Roller Compaction Ribbon Density

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.

Figure 12 from Roller compaction: Ribbon splitting and

&NA; 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).

A Multi-variate Mathematical Model for Simulating the Granule

Mar 10, 2021 · Granule size distribution (GSD) is one of the critical quality attributes in the roller compaction (RC) process. Determination of GSD for newly developed pharmaceutical compounds with unknown ribbon breakage behaviors at the RC milling step requires a quantitative insight into process parameters and ribbon attributes.
