BARRIER FOR REDUCING THE DUST EMISSIONS FOR A COOLER FOR COOLING WARM BULK MATERIAL

摘要

A cooler (1) for cooling hot bulk goods (17) preferably iron ore sinter: The cooler has a grate surface (16) for holding the hot bulk goods (17) to be treated to reduce the dust emissions and at the same time to also enable maintenance measures on the cooler (1). Covers are located in the region of the feed point (2) and the removal point (3). The device herein provides an additional boundary, which prevents the removal of dust particles of size over 150 μm. The boundary is a stationary first wall (12) and a stationary second wall (11) and the boundary extends over a partial segment, and preferably over the entire region, of the uncovered grate surface (16). A supporting structure (18) is provided, to which the first wall (11) and the second wall (12) are fastened.
