The abrasive processing of metal products is accompanied by harmful dust emissions into the work area. Exceeding the MPC of dust particles in the work area has a negative impact on the health of working personnel-it leads to occupational diseases of dust etiology. To localize harmful dust emissions when working on grinding machines, there are various dust collectors and their modifications, which allow to deal with harmful dust emissions with different efficiency. The design of the dust collector shrouds may involve connecting to an aspiration system that creates a low-pressure zone in the housing of the shroud, and thereby helps to remove harmful particles released during work. To correctly calculate the costs of air removed by local suction systems, it is necessary to analyze the dust situation and determine the properties of dust aerosols at a specific enterprise. In this work, the analysis of samples of dust particles selected at the grinding site of the plant for the manufacture of metal-cutting and metal tools, as well as technological equipment of LLC Production Company "Russian tool". Obtaining correct and up-to-date data on the size and chemical analysis of dust particles is necessary for the development of an energy-efficient aspiration system, as well as a mathematical model of the movement of dust particles.
