Powders with angle repose >40° have this type of flow
What is very poor flow?
📐 Angle of Repose & Flowability
< 25° → ⭐ Excellent flow
25–30° → 👍 Good flow
30–40° → ⚖️ Fair/okay flow
> 40° → ❌ Very poor flow
🧠 Quick way to remember:
Lower angle = better flow (particles slide easily)
Higher angle = worse flow (particles stick/friction)
