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.

For performance efficiencies, proper circuitry should be designed around the crusher cone, says Schultz. Importantly, the circuit should be engineered to provide the crusher cone with choke-fed material, or enough material to keep the crusher full. Having too little feed can cause the crusher to side load, which stresses components.
