3.2 CONTROL OF PLANT OPERATIONS Typical crushed-stone plants contain a multiplicity of dust-producing points, including numerous crushers, screens, conveyor transfer points, and storage facilities. Control methods generally applied to plant-generated emissions include wet dust suppression, dry collection, and a combina- tion of the two.

with available water, water sprays may be used to control particulate emissions. In sand processing, water is typically used in clarifiers to sort the sand by size, and the sand is processed wet. Dry particulate control methods (baghouses) may also be used to control particulate emissions.3 SQCS facilities are distributed almost
Thus, material wetted prior to crushing for dust control will likely have to be wetted again to address the additional dry surface area. Wet dust control methods for crushing operations, involve wetting the process material before crushing, after crushing, or both. This is essentially treating the crushing operation as two transfer points, the feed side and discharge side.

emission factors for the crushing, screening, and handling and transfer operations associated with stone crushing can be found in Section 11.19.2, Crushed Stone Processing. In the absence of other data, the emission factors presented in Section 11.19.2 can be used to estimate emissions from corresponding sand and gravel processing sources.
storage pile and sold as base material. The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches).
