Wendling Quarries has expanded operations to include 14 counties throughout Eastern Iowa and Western Illinois.
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.
· Once the ledge has been blasted, a jaw crusher is used to reduce the size of the rocks collected from the quarry. The jaw crusher will take pieces of rock sometimes up to 4 feet in size and reduce the stone down to 1 foot or less. After this, the large pieces of rock will run through the jaw crusher again and the smaller pieces will move onto a ...
