Application number PL20190430614
Publication date 2021-10-25
Application date 2019-07-16

The subject of the application is an apparatus for removing powder produced by ultrasonic atomization, comprising an atomization chamber (1), equipped with an inlet (6) and outlet (8) of gas, and a directing element (7) for gas distribution and gas velocity profile in the chamber (1). The subject of the claim is also a method for removing powder produced by ultrasonic atomization, in which a gas stream (11), which is inert to the atomization zone in the atomization chamber (1), is directed at a pressure range of 0.1 barA to 6 barA and with average velocities of 0.2 to 25 m/s in sections perpendicular to the gas path (11), whereby the gas is distributed substantially perpendicular to the direction of ejection of the droplets of molten material from the sonotrode (2), in such a way that the droplets are entrained and transported by the gas in the atomization chamber (1) in the direction of the outlet (8), advantageously along trajectories (10) close to horizontal, and at the same time are cooled in flight by heat exchange behind the gas until they reach a solid state of aggregation.
