APPARATUS FOR REMOVING FINE ORE ADHERED TO SIZED ORE BY DRUM FEEDERS AND DUST COLLECTING DUCT TO EFFICIENTLY PREVENT DUST GENERATION IN BLAST FURNACE GAS AND DETERIORATION OF AIR PERMEABILITY IN BLAST FURNACE

摘要

PURPOSE: To provide an apparatus for removing fine ore adhered to sized ore, wherein the apparatus separates fine ore when the sized ore passes through the chute and collects the separated fine ore through a dust collecting duct by installing a plural drum feeders inside a transfer route changing chute for changing a moving course of sized ore charged into blast furnace. CONSTITUTION: The apparatus for removing fine ore adhered to sized ore comprises a chute for guiding the sized ore to change a moving course of the sized ore; a pair of drum feeders(30) rotatably installed inside the chute; driven chain gears(34) installed on one side surface of the chute and projected to the outer side of the chute such that the driven chain gears are respectively connected to the pair of drum feeders; a driving chain gear(12) installed on a driving shaft(11) of a belt conveyor(10) and connected to the driven chain gears by means of a chain(40) such that the driven chain gears are rotated; and a dust collecting duct(60) connected to the chute to remove fine ore separated by the drum feeders.
