Bulk material transfer (gravity transportation by chutes) is the most widespread operation for reprocessing mineral raw materials: mining and beneciation of ore and coal, sintering of concentrates, stock preparation in ferrous and nonferrous metallurgy, and production of building materials. Bulk material ow results in considerable dust emission. With the great volume of mineral raw materials that are reprocessed, such dust emissions signicantly impact the overall balance of airborne atmospheric pollution. Dust emissions are dangerous not only from the standpoint of toxicity and occupational disease but also because of the negative impact on the environment.
