Abstract:
A multistage centrifugal atomizer comprises an outer shell that contains an inlet port and an outlet port and that encloses a tundish, a first inclined rotating surface and a second inclined rotating surface. The first inclined rotating surface is opposedly disposed to the second inclined rotating surface. The inlet is used to introduce a molten material into the multistage atomizer and the outlet is used to remove ultrafine particles having a D50 of less than 20 micrometers.
