POWDER CHARACTERIZATION DEVICES
Understanding Powder Properties
- Bulk Density: The mass of powder that can fit into a given volume under normal conditions, determined by filling a measuring cup and leveling the top.
- Tapped Density: The mass of powder per unit volume after removing air through vibration, indicating the maximum packing efficiency.
- Compressibility: The relative reduction in volume from the bulk state to the tapped state, revealing how much the powder compresses under pressure.
- Flowability Index: A comprehensive numerical value combining various powder properties to assess its flow behavior under gravity.
- Angle of Repose: The angle formed between the slope of a powder pile and the horizontal plane when it's at rest, indicating flowability (smaller angle means better flow).
- Angle of Fall: The angle formed after disturbing the powder pile, showing how the powder settles after disruption.
- Angle of Difference: The difference between the angle of repose and the angle of fall, providing further insights into flow behavior.
- Flat Plate Angle (Angle of Spatula): The average angle formed when a flat plate is lifted from a powder pile, indicating flowability (smaller angle means better flow).

The BeDensi Series powder testing apparatus provides a range of six different devices for powder analysis:
- The BeDensi T Pro Series serves as a tapped density tester primarily utilized for testing the tapped density of various powders.
- For measuring the bulk density of metallic powders and granular materials, the BeDensi B1-S functions as a Scott volumeter.
- Crafted to assess the bulk density of non-metal powders, the BeDensi B1 serves as a bulk density tester.
- The BeDensi P is designed to measure the bulk density of plastic and molding materials.
- Precisely crafted for powder angle of repose testing, the BeDensi AR apparatus is utilized for this purpose.
- The HFlow-1 serves as a flowmeter funnel to measure bulk density and flow rate in pharmaceutical and metal powders.
By selecting any of the instruments from the BeDensi Series, users can effectively test the tapped density, bulk density, and flowability of different powder samples.
