Dust Control or Prevention for Crushing and Screening Operations
Crushing creates smaller sized material with an attendant increase in surface area, which will be dry. 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
