The most common containment method for sweeping and milling, Rigsbee said, is spraying water onto the dust. However, after OSHA passed 29 CFR 1926.1153 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.

A classifying cyclone system is needed to achieve a 150 micron (100 mesh) separation. The total volumetric flow rate to the system is 5000 gpm at a solids content of 5% by weight (Ï p=1.02). At an average relative solids density of 1.3, the solids mass flow rate equates to 64 tons/hr.
