For example, for dry silica sand milling a limit size of 1 μm was observed by Mucsi [7]. Cho et al. [10] found a limit size of 30 nm for silica sand in a stirredmedia grinder where the particles were in suspension in water. The presence of water shields the interparticle adhesion and hence it should decrease the formation of agglomerates ...

The most common constituent of sand is silica (SiO2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is resistant to weathering. The composition of sand is highly variable, depending on the local rock sources and conditions. Arkose is a sand or sandstone with considerable feldspar

The most common containment method for sweeping and milling, Rigsbee said, is spraying water onto the dust. However, after OSHA passed 29 CFR in 2017, reducing the amount of dust allowed from 250 micrograms per cubic foot to 50, water alone may no longer be sufficient to suppress silica dust to the standard.
