Powder Tester Powder Strength on storage

Knowing whether or not a powder will flow out of a container depends upon the strength it gains through storage. To allow a powder to flow the force making the powder move must be greater than its strength ( usually called Unconfined Yield Strength).For most powders and granular material, the longer the material is exposed to pressure, the higher its unconfined yield strength will be. This will also be affected by other storage conditions such as temperature and humidity. In a lot of flow measurement tests, the time parameter is often ignored because sample analysis cells required to make many measurements over time are very expensive, and often do not have any means of applying the necessary pressure over prolonged periods. An affordable solution is now available the Evolution Powder Tester.The Evolution measures a materials response to applied pressure and calculates its unconfined yield strength. The measurement can be done at a single point, or at several pressures creating a Flow Function. The sample analysis cells can be stored in a temperature/ humidity controlled environment to simulate different storage conditions and measurements take typically less than 3 minutes to perform. The Evolution can provide you reliable reproducible data for the same cost as having a few samples measured by external laboratories.
