<p>Disclosed is a material segregation apparatus for a blast furnace top bunker, said material segregation apparatus being capable of charging material into the vicinity of the inner wall of the bunker to enhance the material segregation effect. A segregation distributor (6) is disposed at the top of a bunker (2) in such a manner that the segregation distributor (6) is rotatable about the central vertical axis (20) perpendicular to a horizontal cross-section of the bunker (2) and that the vertically lower surface of the segregation distributor (6) receives material (3) charged from above and has an angle greater than the angle of repose of the charged material (3). As a result, the segregation distributor (6) is not liable to interfere with the inner wall of the bunker (2) when the orientation of the segregation distributor (6) is changed, and the charged-material outlet (14) of the segregation distributor (6) can be brought into the vicinity of the inner wall of the bunker (2). Further, the segregation distributor (6) may have a hollow circular truncated cone shape which has an axis line (18) extending at a downward angle and which includes a cutout portion on the side thereof facing the inner wall of the bunker (2) to stabilize the outlet (14) for the charged material (3) and reliably prevent interference with the inner wall of the bunker (2).</p> |
