Principle

The mass flow rate is computed automatically from the slope of the mass temporal evolution measured with the weight scale. The aperture size is modified quickly and easily with an original rotating system.

The measurement and the result analysis are assisted by software. The flowrate is measured for a set of aperture sizes to obtain a flow curve.

Finally, the whole flow curve is fitted with the well-known Beverloo theoretical model to obtain a flowability index (Cb, related to the powder flowability) and the minimum aperture size to obtain a flow (Dmin). The whole measurement is performed easily, quickly, and precisely.

Applications

1. Powders flowability measurements in a silo-funnel geometry.
2. Powders flowability classification for the galenic formulation.
3. A fast and accurate test for production line, able to detect problematic samples before their introduction inside the silo.
4. Predict mass flow for aperture size
5. Predict bag filling rates
6. Suitable for any bag filling, die filling, or capsule filling process
