Sieve Blinding: Why Powder Screens Fail Before the Particle Size Spec Does and How to Solve it
Sieve blinding does more than reduce screening capacity. It changes the material stream. Once particles block, coat, or overload the mesh, the screen no longer applies the intended cut point. That can shift the coarse and fine balance entering the next process step, even when the incoming powder still appears to meet [...]
Changeover Losses in Continuous Powder Lines: 5 Fast Wins to Boost Efficiency
Changeovers can quietly waste hours and tons of product in continuous powder lines. The cause is rarely a single fault. Most losses stem from small oversights that add up—sticky residues, trapped air, timing mistakes, or slow cleanups. Focusing on five targeted actions can reclaim yield, reduce downtime, and improve consistency without incurring new [...]

Powder Percolation Threshold and Conductive Networks in Composite Feedstocks
The powder percolation threshold is the point where conductive particles form a continuous network. Near that point, small changes in dispersion, drying, shear, or oxide growth can swing resistivity by orders of magnitude. Therefore, treat conductivity as a process-controlled property, not only a formulation outcome. Table of contents [...]
Core-Shell and Coated Powders for Controlled Interparticle Chemistry
Core-shell and coated powders let you engineer surface chemistry, improve handling stability, and control sintering and binder wetting by tuning the outer few nanometers. Table of contents When you think about it, powder manufacturing depends on surfaces. Core-shell and coated powders make that dependence usable. [...]
The complexities of infant formula powders
Infant formula powders are far more demanding than simple food powders. Safe infant formula powders depend on tight control of formulation, spray drying, agglomeration, emulsion stability, and packaging, so fragile nutrients stay stable and absorbable from production line to feeding bottle.

Vibration as a Flow Aid: When It Helps Powder Flow
Vibration can improve powder discharge when it breaks a weak arch or releases a local obstruction. However, it can also compact the powder bed, increase segregation, change bulk density, and destabilize feeding. Use vibration as a flow aid only when it matches the failure mechanism. Vibration changes the [...]
Powder Residence Time Can Make the Test Result Miss the Failure
Powder residence time matters because the sample and the failure often describe different moments. A powder tested after drying, blending, conveying, or filling may not be the same powder that reaches the feeder, press, filler, or package later. Hold time can change air content, moisture, bulk density, temperature, consolidation, fines distribution, and segregation [...]
Why Hopper Fill Level Changes Powder Discharge
Do not diagnose a feeder as if the hopper sends it one constant powder. After a refill, the powder near the outlet may still be aerated. Minutes later, the same material may be denser, less permeable, and harder to move. A feeder problem usually announces itself at the [...]

Specialized Powder Processing Techniques: Cryogenic Processing

Cryogenic processing utilizes extremely low temperatures to modify the physical properties of materials, making it an essential technique for specialized powder applications.

Why FIBC Discharge Problems Often Start at the Liner-Spout Interface
FIBC discharge problems are often blamed on the powder being discharged too quickly. In many cases, the real issue sits lower down, at the outlet interface between the liner, discharge spout, receiving hopper, vent path, and bag support. That local geometry can decide whether a big bag empties cleanly, surges, releases dust, or [...]
