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. [...]
