  • Patent number: 10126055
    Abstract: A supply chute, and a system and a method for supplying sinter material from a sinter belt to a sinter cooler (26). A flow of the sinter material (16) is input into the supply chute (1). The flow of sinter material (16) after being input is concentrated by a device in the chute. This means that the flow is remixed for more uniform grain size distribution. The flow is thereafter widened by a widening device in the chute. Then the widened flow of sinter material (16), optionally after making the movement direction of the flow of sinter material (16) uniform, the flow is passed through a segregation device (8,25) and is there segregated, which means that a grain size distribution across the thickness and across the width of the flow is made more uniform. This occurs after the widened flow of sinter material moves in the direction of the output region (5).

  • Patent number: 8876526
    Abstract: A delivery chute for delivering sinter material onto a sinter cooler and a method for delivering sinter material from a sinter belt onto a sinter cooler are provided. The sinter material introduced into the delivery chute may be divided by distributor plates into at least two sinter material subflows flowing in different directions, which may be guided into the edge regions of a sinter material total flow obtained by combining them.
