Abstract

Using the method of aerodynamic classification in the air flow, narrow fractions of dispersed microspheres, related to environmentally hazardous suspended particles PM2.5 and PM10, were separated from high-calcium fly ash from the combustion of lignite coals of the Kansk-Achinsk basin. As a result of a combination of different separation modes, differing in air flow rate, classifier rotor speed and material feed rate, morphologically homogeneous fractions of spherical particles with a narrow distribution dav – 1, 2, 3, 4 and 10 μm were obtained. The characterized fractions of dispersed microspheres are necessary for assessing the risks of anthropogenic impact on the environment associated with the industrial combustion of coal, and can be used to obtain new materials for various purposes
