Granutools, based in Awans, Belgium, a developer of advanced instruments to measure powder behaviour, has introduced its GranuPack Permeability Unit, designed for measuring the permeability of powders under different packing conditions. The tool provides detailed insights into how powders behave when subjected to varying levels of consolidation and density.

The GranuPack Permeability Unit offers users the ability to measure permeability and density simultaneously, providing a more holistic view of powder behaviour. It also is capable of measuring permeability at low consolidation levels and in static conditions.

It features a permeability measurement cell, with a porous frit at its base, that allows air to pass through the powder sample; this design ensures precise and controlled measurements of permeability. A mass flow controller regulates the flow of air within the cell at controlled air flow rates; this precise control over the air flow enables accurate and repeatable measurements.

The unit employs a distinctive measurement technique whereby alternating the application of taps to the powder with air insufflation through the powder bed, it is possible to measure the powder permeability at various packing fractions; this enables a comprehensive understanding of how powders behave under different conditions

The GranuPack Permeability Unit is retrofit-compatible with the GranuPack Classic and can be included in the All-In Maintenance Plan. This solution allows users to upgrade existing equipment without the need for a complete overhaul.
