Can a Screw Feeder Generate Fines Without Milling?

Yes. A screw feeder can generate fines with [...]

Why Can Higher Obscuration Create False Fines?

A finer PSD at higher obscuration does not [...]

Rotary Valve Failure Modes: How Powder Properties Drive Leakage, Wear, and Jamming

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.

Why Can XRF Results Change With Particle Size?

A reported XRF concentration depends on the prepared specimen [...]

Why Does an NIR Moisture Reading Shift When Particle Size Changes?

NIR moisture predictions depend on both water absorption [...]

LFP Cathode Powder Production: How Spray-Drying, Calcination, and Pulverization Set Particle Size and Tap Density Targets

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.

Refractive Index in Laser Diffraction: D10 vs D50

Laser diffraction calculates particle size from measured scattering [...]

Why Can Permeability Fall After Milling?

Milling can reduce powder-bed permeability even when [...]

Cyclone Separation of Fine Powders: Cut Size, Efficiency Curves, and Agglomeration

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.

Micronization by Jet Milling: How Classification, Milling Intensity, and Time Change Surface Properties

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.
