Vacuum melting inert gas atomization equipment is designed for producing metallic spherical powder by atomizing under certain conditions.
Working principle: Metal or alloy materials are melted under inert gas protection or vacuum condition, and the molten metal is poured through insulation tundish system into a gas nozzle where the melt stream is disintegrated into droplets by high pressure inert gas stream. The small droplets will be solidified into tiny spherical powders in flight in the atomization tower.

The equipment is composed of vacuum smelting system, atomization system, gas supply system, powder collecting system, cooling water system, system integrated control system,atomizing tower support, steel structure platform and so on. 

system for selection:

1.Atomizing gas heating device
2.CCD video surveillance system (to observe equipment operation status in time)
3.On-line laser particle size monitoring system
4.Online oxygen content monitoring system
5.Pressure difference controlling system
6.Fluid limiting diversion tube heating system
7.Pneumatic powder classification system
8.Multistage high vacuum melting system (max. vacuum degree: 6.7x10-3Pa)
9.Melting and Atomizing temperatures monitoring system

Combined with high vacuum technology, high temperature melting technology and high pressure gas atomization technology, vacuum melting gas atomization powder manufacturing equipment is especially suitable for the production of high quality powders and active metals/alloys.The atomized powder feature high purity, low oxygen content, high yield of fine powder, good appearance,etc.

In 2012, a company from the Middle East, the manufacturer of gas added bricks, asked us about the best solution to highly-active aluminum powder production. After technical discussion and field study, this production line had been put into production at the beginning of 2014, which was highly praised by the customer.
250kg vacuum melting gas atomization equipment is under pre-assembly in our factory. The pre-assembly is conducted in reduced atomizing tower and steel structure platform. And the customer will come to our factory for pre-acceptance at the end of this month. This equipment is expected to deliver to client's site before the middle of next month.
