Abstract

PURPOSE: To improve productivity while increasing granularity and improving air permeability during a sintering process, by previously adding water to a material to be sintered before it is charged in a mixing tank provided in front of a primary mixer, and granulating the material.
CONSTITUTION: When powder of a material is from a main vessel 10 are reservoired on a rough ore yard 13 through conveyors 11 and 12, a humidity regulating mixer 14 is installed at a halfway point and water is sprinkled from sprinkling nozzles 15 before granulation. Materials reservoired on the yards 13 are mixed at a prescribed ratio and then reservoired on a blending yard 16, but another humidity regulating mixer 19 may be installed between conveyors 17 and 18 inserted of or as a substitute for said mixer 14 to perform the water sprinkling from sprinkling nozzles 20 and granulation. Thus, materials to be charged in the blending tank are granulated previously in the humidity-regulating mixers, improving the granulation index of each brand greatly.
