Abstract: As the main equipment for the industrial production of metal powder, vacuum atomization milling equipment is widely used in key areas including additive manufacturing, powder metallurgy, aerospace and medical treatment. This paper focuses on the most common vacuum atomization milling technology, and their characteristics and development directions are deeply studied and discussed. Firstly, the technical background of atomized milling and the common classification of current milling methods are briefly introduced, and then combined with the core performance indicators of the technology and equipment used by the major atomization milling equipment manufacturers and metal powder suppliers, the vacuum atomization milling methods including VIGA(vacuum induction-melting gas atomization), EIGA(electrode induction-melting inert gas atomization), VIGA-CC(water-cooled copper crucible vacuum induction-melting gas atomizing) and PREP (plasma rotating electrode-comminuting process)are described in detail. The future development direction of atomization milling technology and equipment is also prospected.
