Aug 31, 1983 The U.S. EPA classifies and regulates dust, smoke, and soot by particle size. The particle size measuredis in microns. Dust or PM less than or equal to 10 microns in diameter is commonly referred to as PM. 10. Most dust associated with crushing facilities falls into this category. Finer sources of PM equal to or smaller than 2.5 microns PM. 2.5
Aug 02, 2017 Quarries. Stone quarrying is a process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into desired sizes. This screened aggregate is then used for the construction of roads, rail lines, bridges, hospitals, schools, airports, factories, and homes, all of which has crucial impact on economic development of any country.

Jun 09, 2020 Dust is an environmental issue at many quarries and crushing is the most significant source of it 1, 2.According to Sairanen and Selonen drilling is the most dust producing activity in natural stone quarries.Aggregate production is reported to generate mainly coarse PM 10 or larger particles 4, 5, whereas the majority of the dust generated during the drilling is PM 10 .
It is concluded from this research the particulate generated from stone crushing activities contain a significant amount of respirable particle. The amount of free silica in stone quartz is 85 to 97 percent that emission of particles effect to health workers. LEV has important effect in the removal of silica particles in stone crushing units.

Abstract Fugitive dust constitutes one of the most severe environmental problems in quarries because it escapes capture. This review aims to provide overview of dust concentration caused by quarrying by synthesising the current knowledge. The 25 studies explored here were conducted in open-pit quarries or mines. Three main dust sources surfaced from the studies drilling, crushing and hauling.
Dust constitutes one of the major environmental concerns near many aggregate quarries, with crushing often being the most significant source. In this study, dust emissions and dispersion measurements were conducted under real operating conditions at six aggregate quarries in southern Finland.
