Title:
GRANULATION DEVICE, METHOD FOR PRODUCING GRANULATION SINTERING RAW MATERIAL, AND METHOD FOR PRODUCING SINTERED ORE
Document Type and Number:
WIPO Patent Application WO/2023/210411
Kind Code:
A1
Abstract:
Provided are: a granulation device capable of efficiently heating a sintering raw material by blowing steam into the sintering raw material; a method for producing a granulation sintering raw material; and a method for producing a sintered ore using the method for producing a granulation sintering raw material. This granulation device granulates a sintering raw material including an iron-containing material, a CaO-containing raw material, and a coagulation material. The granulation device has: a cylindrical drum that rotates around the horizontal direction as a rotation axis and is provided with an inlet through which the sintering raw material is put in, and a discharge port through which the granulated sintering raw material is discharged; a steam pipe provided inside the drum and provided only in an anterior half portion between the inlet and the intermediate position between the inlet and the discharge port; and multiple nozzles which are connected to the steam pipe and from which steam is ejected toward a deposition surface of the sintering raw material, wherein the multiple nozzles are provided 500 mm or more apart from the deposition surface of the sintering raw material.
