PARTICULATE RAW MATERIAL GRANULATION METHOD AND SINTERED ORE PRODUCTION METHOD

WIPO Patent Application WO/2022/215584

A1

According to the present invention, in a bottom surface of a pan 1 on which a scraper 2 is disposed in a specific state, if a straight line at which a virtual extension surface of a side surface 21 of the scraper 2 intersects the bottom surface and an extension line thereof are defined as a virtual straight line a, and if a straight line passing through the center p of the bottom surface of the pan 1 and parallel to the virtual straight line a is defined as a virtual straight line b, a particulate raw material is poured into the pan 1 such that a particulate raw material-pouring position x is located closer to the center p of the bottom surface of the pan 1 than is the virtual the straight line a, and a center px of the particulate raw material-pouring position x is located between the virtual straight line a and the virtual straight line b, and a liquid is poured into the pan 1 such that a center py of a liquid-pouring position y passes through the particulate raw material-pouring position x, is located on a virtual straight line c parallel to the virtual straight line a, and falls within a circular region e having a radius of 0.6r, where r is the radius of the pan 1.
