Working Principle :
The Principle of the rotary injector system is that the inert gas such as N, Ar is injected into the GR- DLA assembly i.e. rotating member and is released through openings at the rotor.

When rotating at Speeds 350rpm to 450rpm, the disperser shears the incipient gas bubble released, producing a wide dispersion of very fine bubbles for degassing.

The high surface area to volume ratio of degassing bubbles provides greatly increased contact area and therefore, increased reaction kinetics, resulting in more efficient degassing . The rotating member also disperses the bubble array more uniformly, within the reaction vessel to provide more thorough mixing of metal with the purge gas.

Hydrogen diffuses into the purge gas bubble, which rises to the surface of the melt and is expelled into the atmosphere.
