摘要： PROBLEM TO BE SOLVED: To provide a method for charging a sintering raw material capable of attaining the grain size segregation of a sintering raw material by a relatively easy means.
SOLUTION: In the method where a sintering raw material is charged onto a sintering machine pallet through a roller feeder composed of a plurality of driving rollers from a feeder below a feed hopper in a sintering machine, operation is performed in such a manner that the circumferential speed of each driving roller is controlled per the unit of the roller group or the individual rollers so as to make that on the upstream side higher than that on the downstream side. Among the plurality of rollers, the circumferential speed of the rollers from the roller on the uppermost stream side to the position of the roller equivalent to the downstream side by 40 to 60% is made higher.
