Calcium Carbonate Powder in Polypropylene: Dust Suppression and Dosing Errors
Dust suppression oil can reduce airborne calcium carbonate dust, but it may also increase powder cohesion. In polypropylene compounding, that change can disturb loss-in-weight feeder refill behavior, causing bridging, rat-holing, delayed settling, and unstable screw feed. Before changing the feeder hardware, check whether the calcium carbonate surface treatment has altered the powder’s flow [...]
Real-Time Particle Characterization and Process Control
Real-time particle characterization is moving powder processing from delayed laboratory checks toward inline sensors, soft sensors, and hybrid models that support faster process decisions. The major shift is the interpretation of sensor signals through particle-scale mechanisms. Pressure, vibration, acoustic, optical, thermal, and process data can increasingly be linked to changes in particle size, [...]
Fine Powder Fluidization in Pneumatic Conveying and Discharge Control
Fine powder fluidization can support controlled pneumatic conveying, especially in dense phase systems where lower velocity helps reduce wear and product damage. Problems appear when entrained air remains in the powder after transfer. At that point, the receiving hopper, feeder, outlet, or filling step may see flushing, segregation, delayed discharge, or weight variation. [...]
Sustainable Powder Metallurgy: Powder Reuse, LCA, and Circular Manufacturing
Sustainable powder metallurgy depends on controlled powder loops, not on powder processing alone. Powder-based manufacturing can reduce waste, improve material efficiency, and support circular metal production, but only when powder production, reuse cycles, contamination, sintering energy, and life-cycle data are managed as one system. Table of contents: sustainable powder [...]
Metal Powder Feedstock Quality in Additive Manufacturing: From Particle Behavior to Part Performance
Metal powder feedstock quality has a direct effect on print stability and part reliability. Particle size distribution, morphology, oxygen level, surface condition, flow behavior, packing density, and reuse history all influence how powder spreads, melts, and consolidates. In additive manufacturing, a strong alloy concept can still fail when the powder feedstock is poorly [...]
