$Powder segregation diagnosis during hopper filling showing coarse and fine fractions separating in an industrial powder transfer process$
Powder Segregation Diagnosis During Mixing, Conveying, and Filling
Powder segregation diagnosis starts by locating where the blend loses uniformity. Some blends leave the mixer in spec and drift only during transfer, filling, or discharge. In practice, the main mechanisms are sifting, fluidization, trajectory segregation, and dusting. Each one is triggered by a different combination of particle properties, airflow, and equipment geometry. [...]
Why Bulk Powder Behavior Depends on Contact Networks, Not Just Particle Size
Bulk powder behavior is not controlled by particle size alone. In many systems, the real driver is the internal contact network between particles. As stress, consolidation, refill, or storage conditions change, that network changes too. That shift can determine whether a powder flows smoothly, bridges, rat holes, or feeds inconsistently. [...]
Why Free-Flowing Powders Still Arch in Hoppers, and How to Diagnose the Real Cause
A powder can look easy to handle in a funnel test and still block a hopper in production. The reason is simple. Most quick “free-flow” tests describe loose, low-stress behavior, while hopper arching is a failure of a consolidated powder bed under static load. If shear testing shows a critical arching dimension larger [...]
Functional Importance of Porosity in Food Powders
Article updated February 2026 Porosity controls hydration speed, dissolution, compressibility, and storage stability in food powders because it sets how easily water and gases access the particle interior. Define a target porosity window for the product intent, for example, instant rehydration in spray-dried powders versus shelf stability in denser milled powders, then [...]
$Refractory alloy powders for rocket propulsion, photorealistic lab scene with metal powder and AM test coupon$
Concentrated Refractory Alloy Powders for Rocket Propulsion
Concentrated refractory alloy powders for rocket propulsion only create value when you treat them as a full chain problem. Alloy design, powder synthesis, powder quality, build strategy, and oxidation protection must align. If one link drifts, the part fails early, even when the alloy concept is sound. Table of [...]
