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

摘要

The invention relates to a cooler (1) for cooling hot bulk material (17) which has a grate surface (16) for receiving the hot bulk material (17) to be treated, preferably iron ore sinter. The task is to reduce the dust emissions and at the same time to allow maintenance of the radiator (1). The object is achieved by a device which, in addition to the already existing covers - which are located in the region of the feed point (2) and the removal point (3) - provides an additional limitation which prevents the removal of dust particles of more than 150 .mu.m. The boundary consists of a fixed first wall (12) and a fixed second wall (11) and preferably extends over a partial section over the entire area of the uncovered grate surface (16). Furthermore, a support structure (18) is provided on which the first wall (11) and the second wall (12) are attached.
