Basic Flowability Energy Measured by Powder Flow Cell

Anton Paar Modular Compact Rheometer series (MCR) can be equipped with a Powder Flow Cell and the helical two-blade stirrer which is open to expand dynamic measurements of powders and the determination of their properties in motion. Dynamic flow characteristics are calculated by upward and downward movements of the stirrer within the sample medium.

Understanding the flowability of powders can be crucial in many areas of production and handling. Both internal effects and external factors affect and change the behavior of granular media. External factors can be easily quantified using dynamic flow characteristics. The combination of the required helical two-blade stirrer and the specific moving protocol, allow the calculation of various dynamic flow parameters for quality control, such as basic flowability energy (BFE), stability index (SI), flow rate index (FRI) and specific energy (SE).
