Environmental GUIDELINE ON STONE CRUSHING plant

Environmental Guideline On Stone Crushing Plant

A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes coarse aggregates, crusher run, rock sand and other fine aggregates from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making.
