Document Type and Number:
Japanese Patent JP3058985
Kind Code:
B2
Abstract:
PURPOSE:To improve the productivity of sintered ore even if pulverized ore is blended by beforehand granulating the pulverized ore together with a part of sintering main and auxiliary raw materials and directly carrying into a surge hopper without mixing with mixed granular materials of the remained sintering raw materials. CONSTITUTION:The pulverized ore 2 containing >=70wt.% of <=0.125mm particles together with a part 3 of the main and auxiliary raw materials and powdered coke 5 in the sintering raw materials stored in hoppers are discharged into a granulating machine 1 and binder 4 and water 6 are added beforehand to execute the granulation. On the other hand, the remained sintering raw materials 9 and the powdered coke 5 are mixed and granulated by a mixer 8, etc. Successively, the former pre-granulated material 7 and the latter mixed and granulated material 10 are continuously charged to a belt conveyor 13 without executing mutually mixing treatment, and are separately and directly carried into a surge hopper 12 of sintering machine 11. By this method, at the time of manufacturing the sintered ore by sintering the iron ore, a large quantity of the pulverized ore as a sintering raw material can be blended and also, the productivity of the sintered ore can be improved.
