【 摘 要 】

Flask is a siliceous microporous sedimentary rock. Recently, it is increasingly used as a sorbent and as an additive to building materials. An important process for obtaining a product is crushing, sifting, roasting, and so on. All of them are accompanied by dust. This dust may be a pollutant of the air, waste, etc. The article presents the results of experimental and field studies of the fractional composition and aerodynamic characteristics (sedimentation rate) of the dust of the flask of various deposits. An experiment was carried out, the installation was described, as well as the data processing technique. The integral functions of the mass distribution of the dust particles of the flask across the diameters in the probabilistic-logarithmic coordinate system are constructed, both for the whole ensemble of particles and for particles of different ranges of sedimentation rates.
