Abstract

Abstract The intensive development of the infrastructure of large cities, which took place in the second half of the twentieth century, led to the fact that enterprises specializing in the production of building materials and products were in close proximity to urban residential areas. This determines an increase in the requirements for the efficiency and reliability of dust removal systems designed, as is known, to ensure the standardized quality of the air environment of settlements and industrial premises. The dust generated in the production of building materials, in many cases, has abrasive properties, which leads to accelerated wear of the elements of dust cleaning systems. The experience of using such systems shows that dust collectors, as well as shaped parts of air ducts (bends, tees, etc.), through which the dust and gas mixture is transported to dust collectors, are most susceptible to abrasion. Abrasive wear of dust collectors during operation leads to an increase in dust leakage into the atmospheric air into the air of the working area. During operation of a dust-cleaning unit under pressure, damage to the walls of the air ducts also leads to knocking out the transported dust. The supercritical wear of the elements of the dust removal system leads to its failure. The article presents some results of studies of the dust properties of building materials that determine the process of abrasive wear.
