Drum Feeder) is attached and the raw material of sinter is cut out.

The raw material sintered by the drum feeder is moved downward along the deflector plate to cause grain size and component segregation, and fine particles are charged into the upper layer of the sintered layer and coarse particles are charged into the lower layer of the sintered layer. The sinter raw material charged into the pellet truck is adjusted in height so as to uniformly fill the cut-off plate in the longitudinal direction.

At this time, there is a problem that uniform width firing can not be performed due to the difference in density charged in the width direction.
