19 September 2026Vacuum Conveying for Fine and Hazardous Powders: Containment, Velocity, and Filter Design
Vacuum conveying contains by default: any breach draws air inward rather than pushing powder out. That containment advantage comes with a fixed pressure budget, and filter design competes directly with conveying velocity for every millibar of available driving force.

25 July 2026Dense-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.

11 July 2026What Rotary Airlocks Actually Do to Powder
Rotary airlocks function as pressure boundaries as much as metering devices. The rotor tip clearance governs particle attrition at the nip zone and the rate of fine-particle bypass under differential pressure. As clearance widens through wear, the downstream particle size distribution shifts in a pattern frequently misread as upstream process variation.
