Powder Characterization
Granutools GranuPack, GranuFlow & GranuDrum
The Granutools powder analysis suite (GranuPack, GranuFlow, and GranuDrum) provides quantitative evaluation of powder packing behavior, flowability, and cohesion under dynamic conditions. These measurements are critical for understanding powder performance in LPBF, DED, cold spray, and powder metallurgy processes.
- GranuPack Tapped density, packing dynamics, and Hausner ratio
- GranuFlow Flow rate and flowability
- GranuDrum Cohesive index and dynamic avalanche angle (powder rheology)
- Relevant Processes LPBF, DED, cold spray, powder metallurgy
Unique Capabilities
- Packing dynamics (GranuPack)Tracks how bulk density evolves under repeated taps, quantifying packing behavior relevant to powder bed spreading and die filling.
- Flowability and cohesion (GranuFlow)Provides a repeatable measure of powder flow and inter-particle cohesion for comparing powder lots and feedstock conditions.
- Dynamic rheology (GranuDrum)Rotating-drum measurement of avalanche angle and cohesion reflects how powder behaves in motion, as it does during recoating or feeding.
