The primary environmental impact from aggregate, stone, and industrial mineral mines in New Mexico is degraded air quality from stack emissions and disturbed areas on the mine. Surface and groundwater quality impacts from such mine are relatively benign in New Mexico due to the semi-arid climate and lack of perennial streams.
Impact crushers reduce mineral materials such as concrete, asphalt and natural rock in size to produce a valuable commodity product. A fast spinning rotor throws the material against a solid stationary impact wall. The striking and impacting causes the material to shatter into smaller pieces. The result is a very homogenous and cubical product ...
