Powder flow property measurements generally fall into two main categories: dynamic analysis and static analysis. Dynamic instruments measure powder flow properties as the test material is moving or is about to move.
Static instruments measure powder that is not moving and typically has been exposed to pressure. For a complete picture of a material’s flow behavior, both types of testers are required. For solving specific flow problems, usually one type of tester or test is required.
The Revolution Powder Analyser can measure your powder’s ability to flow, consolidate, granulate, cake, pack and fluidise by measuring the power, time and variances in power of your powder in a rotating drum. This data can be used to quantify your powder’s particle behaviour during process applications such as blending, tableting, mixing and transportation. The Revolution is both easy to load and automatic, eliminating the opportunity for human error.
The REVOLUTION Powder Analyser consists of a rotating drum that measures the flow properties of granular and fluidised materials. Several drum sizes are available, from drums requiring 10 cc’s of sample to drums using 500 cc’s.
A stepper motor turns high precision silicone rollers which in return rotates the drum. The operator can set the drum rotation rate (range 0.1 to 200 RPM) and prep time (range 0 to 999 seconds) of the analysis. A digital camera with the assistance of back-light illumination takes digital images of the powder during the rotation process. The images can be accumulated up to a rate of 30 frames per second.
Using patent pending algorithms, the software measures the behaviour of the powder from the images collected due to the drum rotation and how this behaviour changes over time. This data is then used to calculate various parameters representing the powder’s quality and process ability.
Caking, Flowability, Fluidisation, Granulation, Multi-Flow and Packing parameters can all be measured quickly and easily.
