Effect of roll-compaction and milling conditions on ...

2016-9-1  The compaction was made at room temperature (25 °C, 45 ± 2% RH) at 5 mm/min of speed (quasi-static). For each pressure level, the mean of three replicates was calculated. Different milling parameters result in different particle size distributions and wide ranges of granule size can exhibit different compaction properties.

On a roll: Examining the principles of roller compaction ...

2018-12-12  Roller compaction is a method of powder compaction of dry powders into a solid mass known as the ribbon. This process is achieved by feeding powder through a set of directly opposed, counter-rotating rollers. The process avoids the use of liquids and high temperatures. The ribbon is broken down into a specific granule size via a milling

The flowability of the roller compacted substances was determined either with the Schulze shear cell (FF1-2C value) or using the Hausner ratio (Graph 2). To obtain flow index (FFC) values indicating good flow, a minimum of 25 kN compaction force during roller compaction was needed. At the same time, all samples exhibited good
