PROBLEM TO BE SOLVED: To provide a method and equipment for charging raw materials by which the air permeability of a bed of raw materials for sintering at both ends in the width direction of a pallet can be suppressed and the quality and yield of sintered ore can be improved. SOLUTION: In the method and equipment for charging raw materials, when the raw materials are charged into a sintering machine by charging the raw materials 7 from an ore-feed hopper 2 onto a pallet via a feed rate adjusting device, a feeder and an ore-feed device having a particle-size segregation function, the raw materials 7 are charged, in the central part in the width direction of the pallet, via the ore-feed device having a particle-size segregation function and the raw materials 7 are charged, in the vicinity of both ends in the width-direction of the pallet, by being allowed to fall directly onto the pallet without being passed through the ore-feed device having a particle-size segregation function. In the above charging method and equipment, the ore-feed device having a particle-size segregation function consists of a flow plate 10 and an ore-feed chute 5 or of the ore-feed chute. It is preferable that the range of the vicinities of both ends in the width direction of the pallet is made to≤10% of the overall width of the pallet. COPYRIGHT: (C)2005,JPO&NCIPI
