POWDER AND DUST MATERIALS FEEDER FOR METALLURGICAL MELTS INJECTION TREATMENT PLANT Russian patent published in 2006 - IPC B65G53/50 C21B7/16 C21C5/48

Abstract RU 2268224 C1

FIELD: metallurgy; injection treatment of melts with powder and dust materials.

SUBSTANCE: proposed feeder has two hoppers with materials charging devices and aeration chambers, materials injection chamber with shutoff-and-control device connected with aeration chambers of hoppers. Aeration chambers of hoppers are connected with injection chamber through side charging holes, diameter of each charging hole is 0.05-0.10 of diameter of injection chamber, and capacity of aeration chamber of each hopper is equal to 3.0-10.0 of that of injection chamber.

EFFECT: improved stability of regulated delivery of homogeneous mixture of powders or dust into pneumatic transportation line.
