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.

Coarse aggregate (stone) The aggregate with particle size between 4.75 mm and 9.0mm is coarse aggregate, commonly known as the stone. It can be divided into two types, that is, gravel and pebble. Gravel is natural rock or rock by mechanical crushing, screening system, and the particle size is larger than 4.75 mm of rock particles.
