When a rotary airlock valve leaks, wears, or jams, the cause usually lies in the powder rather than the equipment. This insight maps cohesion, abrasiveness, bulk density, and particle size distribution to distinct failure patterns and explains what each pattern tells you about the powder state.
A reported XRF concentration depends on the prepared specimen [...]
NIR moisture predictions depend on both water absorption [...]
LFP cathode powder quality is built in stages, not inspected at the end. This article follows the precursor-to-powder route and shows why particle size distribution and tap density are the measurements that actually tell you whether the synthesis worked.
Laser diffraction calculates particle size from measured scattering [...]
Milling can reduce powder-bed permeability even when [...]
The classical cyclone cut size model assumes discrete, non-agglomerating particles. Cohesive or moisture-sensitive fines can travel through a cyclone as agglomerates instead, which changes what a PSD result actually tells you about classifier performance.
Jet milling micronization reduces particle size through particle-particle impact controlled by classifier wheel speed and feed rate. Pushing the cut point lower can raise amorphous surface content and hygroscopicity in ways a passing PSD result will not reveal. This guide covers the mechanism and the tests that actually diagnose a changed lot.
