ROCK CRUSHING PLANT APPLICATIONS ADVICE
These are referred to as “regulated air pollutants.” In addition, there may be emissions of hazardous air pollutants (HAPs), primarily formaldehyde from the engine(s). In general, a rock crushing plant will have a primary crusher, primary screen, secondary crusher(s) and secondary screen(s), and associated conveyors and stockpiles.

The table above shows the most popular blasting media as coal slag, copper slag, sand, and hematite. The study showed the range of blast pressures used as 80 PSI (per square inch) to 120 PSI. Very limited information is available on emission factors for particulate emissions resulting from dry abrasive blasting.

Air Emissions Factors and Quantification | US EPA
Air Emissions Factors and Quantification. An emissions factor is a representative value that attempts to relate the quantity of a pollutant emitted with an industrial activity. Emissions factors are tools for building emissions inventories, guiding air quality management decisions and developing emissions control strategies.
