centrifugal atomization

Centrifugal Atomisation - an overview ScienceDirect

Centrifugal Atomization. This technique is an intermediate between laboratory and commercial production ones. The centrifugal atomization was used [21] for manufacturing Al-Cu-Fe powder with a QC component. The several hundreds grams ingot previously melted in an induction furnace in argon environment was remelted in a crucible placed in the center of the atomization chamber in a helium

Atomization Concept and Theory - Graco

2015-1-27  Centrifugal Atomization In centrifugal or rotary atomization, a nozzle introduces fluid at the center of a spinning cup or disk. Centrifugal force carries the fluid to the edge of the disk and throws the fluid off the edge. The liquid forms ligaments or sheets that break into fine droplets. Figure 9 shows the mechanism of centrifugal atomization.
