The proposed project entails the establishment of a rock-quarry, Crusher for crushing the boulders into aggregates of different sizes, Concrete Batching Plant, Asphalt Mixing Plant, stock pile area and other support facilities. These facilities that are proposed by the proponent are meant to aid the dualling of Sagana-Marua (A2) road project.

Washing and classifying also may be used in processing manufactured sand. The crushing process creates a significant amount of "fines," which are undersized fine particles that pass through the smallest screen openings (which are measured by mesh sizes). The minus-#100 and minus-#200 mesh fines require washing to be removed.

Facilities can and often do utilize storm water and process water collected in onsite systems, repurposing that water back into the production process at the facility for aggregate cooling, dust suppression and wash-down for trucks. ...
