METHOD FOR PRODUCING PELLETS OF MAGNESIUM OR ITS ALLOYS Russian patent published in 2006 - IPC B22F9/10 C22B26/22 

FIELD: non-ferrous metallurgy, namely processes for producing pellets of magnesium or its alloys.

SUBSTANCE: method comprises steps of preparing salt mixture, loading magnesium or its alloy into melt salt mixture; agitating mixture, cooling it, milling for producing mixture of salt component and pellets; further separation of salt and metallic components in the form of pellets. Novelty is feed of milled mixture of salt component and pellets in compressed air stream; twisting flow in centrifugal chamber with tangential inlet; then removing salt component out of centrifugal chamber and depositing metallic components in the form of pellets onto bottom of centrifugal chamber; discharging pellets out of chamber. Air flow speed at inlet of centrifugal chamber is in range 50 - 400 m/s. Salt component discharged from chamber is directed to cyclone. Mixture of salt component and pellets is fed to compressed air stream by injection.

EFFECT: intensified stage of separating salt phase and pellets of magnesium or its alloys, possibility for producing improved-quality product.
