Blast furnace feed device

摘要

Furnace loading system comprises on the mouth of the furnace from top to bottom a large dome, a medium sized dome, a small dome and a rotating grid dome. Each dome cooperates with a corresponding grid so that the raw material is dropped and spread evenly on the small, then on the large dome, passing over the intermediate dome. It is finally discharged into the furnace over the large dome which opens for this purpose.
