Currently, the main means of dust control in the departments of medium crushing are sheltering dusty equipment and separate units of mechanisms and devices; aspiration of dusty air from under the shelters of vibrodionic screens, hammer crushers and ore transfer units on conveyors with subsequent purification of air from dust in dust-collecting installations such as SIOT; moistening of ore on feeders and dust removal.
A methodology for calculating the deposition time of hygroscopic aerosol particles in an air stream with relative humidity exceeding the hygroscopic point of dust particles is proposed. Calculation formulas allowing to estimate the time of particles deposition at different stages of their growth due to condensation and gravitational coagulation are presented.
