A cooler () for cooling hot bulk goods () preferably iron ore sinter: The cooler has a grate surface () for holding the hot bulk goods () to be treated to reduce the dust emissions and at the same time to also enable maintenance measures on the cooler (). Covers are located in the region of the feed point () and the removal point (). The device herein provides an additional boundary, which prevents the removal of dust particles of size over 150 &#x3bc;m. The boundary is a stationary first wall () and a stationary second wall () and the boundary extends over a partial segment, and preferably over the entire region, of the uncovered grate surface (). A supporting structure () is provided, to which the first wall () and the second wall () are fastened.

Delimitation for reduction of the dust emissions for a cooler for cooling hot bulk material

A supply chute, and a system and a method for supplying sinter material from a sinter belt to a sinter cooler (). A flow of the sinter material () is input into the supply chute (). The flow of sinter material () 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 (), optionally after making the movement direction of the flow of sinter material () uniform, the flow is passed through a segregation device () 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 (). After passing through the output region (), the flow of sinter material () is supplied to the sinter cooler (), wherein the horizontal main component B of the movement direction of the flow of sinter material is largely perpendicular to the horizontal main component A of the movement of sinter material by the sinter belt.
