Virgin-to-Reused Powder Blend Ratios in Aerospace PBF-LB Qualification: Where the Decision Actually Sits
As aerospace metal additive manufacturing capacity expands, more reused powder is going back into qualified builds. The virgin-to-reused blend ratio decision depends on PSD shift, satellite formation, and morphology drift, and cannot be settled by a single powder check disconnected from the part's stress state.
Dense-Phase vs Dilute-Phase Pneumatic Conveying: Matching Conveying Mode to Attrition and Segregation Risk
Dense-phase and dilute-phase pneumatic conveying create different particle contact mechanics, and the resulting attrition and segregation risk depends on velocity, solids loading ratio, and the powder's own attrition sensitivity, not on a fixed assumption about which mode is gentler.
Cement and Concrete Powder Processing: Fineness, Grinding Aids, and Cementitious Reactivity
Cement fineness is not a single number. Blaine surface area, particle size distribution, grinding aid chemistry, and moisture history each pull on hydration reactivity in different ways, and a fineness specification that ignores any one of them will eventually let a bad batch through.
Fluidized Bed Processing in Powder Technology: Granulation, Coating, and Drying Through a Powder Behavior Lens
Geldart classification, minimum fluidization velocity, bubble dynamics, droplet-to-particle size ratio, and permeability all determine whether a fluidized bed process delivers controlled granule growth, uniform coating, or consistent drying at production scale.
Spray Drying 4.0: Real-Time PAT, AI Process Control, and What Engineers Actually Gain
Process analytical technology combined with machine learning is changing residual moisture control and yield prediction in pharmaceutical and food spray drying. The gains are real but bounded, and the off-line test panel has not been replaced.
