One of the negative changes in the Earth’s ecosystem is air pollution from cement production waste. Cement industry enterprises annually emit more than 27 million tons of dust into the environment. They account for 2/3 of industrial emissions of solid substances and 44% of gaseous ones. The construction of various facilities is increasing every year. This leads to increased cement production and additional pollution. The most dangerous is fine dust (particle size less than 10 microns). It was found that a significant part of the fine dust is carried away by the exhaust gases even before entering the stage of dry cement formation. It is deposited in various production facilities. Further dust can enter the atmosphere from the workshops and cause pollution. Collecting it is a very complicated and expensive process. In the article, the design of a machine for collecting and unloading cement dust makes it possible to collect about 69% of all dust in the workshop and on the territory of the plant and load it into a special container. This significantly improves the ecological state of the air.
