APPARATUS CAPABLE OF SEPARATELY CHARGING HEARTH LAYER ORE INTO SINTERING MACHINE PER GRAIN SIZES OF THE HEARTH LAYER ORE

摘要

PURPOSE: An apparatus capable of separately charging hearth layer ore into sintering machine per grain sizes of the hearth layer ore is provided to sequentially charge hearth layer ore separated per grain sizes into the sintering machine by separating hearth layer ore per grain sizes when charging hearth layer ore into the sintering machine. CONSTITUTION: The apparatus capable of separately charging hearth layer ore into sintering machine per grain sizes of the hearth layer ore comprises a hearth layer ore chute(10) which is connected to feeding feeder(121) of hearth layer ore hopper(104) so that hearth layer ore(117) is supplied into the hearth layer ore chute(10), and at the lower part of which a plurality of feeding chutes are installed to separately feed hearth layer ores(117) separated per various grain sizes into the sintering machine(106); a plurality of hearth layer ore grain size separating rolls slantly installed at the upper side of each of the feeding chutes of the hearth layer ore chute(10) in such a way that the hearth layer ore grain size separating rolls are driven by a motor(32) to separate the hearth layer ore into certain grain sizes; and a negative pressure sensor(50) installed at wind box(111) at the lower part of the sintering machine(106) to adjust feeding of the hearth layer ore by measuring negative pressure of air in the wind box(111).
