Loss in Weight Feeder Drift After Refill: The Refill Shock Mechanism and How to Diagnose It
Loss in weight feeder drift often starts at refill, not at tuning. Each refill changes packing density and air content at the screw inlet, so the same screw speed meters a different solids fraction for minutes. Why refills create a hidden process step Most teams treat a [...]
Deaeration lag, why “easy flowing” powders still surge
Deaeration lag in powders creates a timing mismatch between how fast your process cycles and how fast trapped air can escape under hopper stress. That mismatch drives pause and surge discharge, density swings, and feeder instability. Fix the air pathway first. Reduce air entrainment during fill, verify vent capacity under real dust load, [...]
Permeability Collapse in Hopper Discharge Causes “Random” Ratholes and Sudden Flooding
Permeability collapse in hopper discharge often triggers instability before cohesion becomes the main driver. When air cannot move through the bed fast enough, a local vacuum forms, effective stress rises, and a rathole stabilizes. When that structure collapses, trapped air can drive flooding and sharp discharge surges. If [...]

Specialized Powder Processing Techniques: Cryogenic Processing
