Stone Crusher

In industry, a crusher is typically a machine which uses a metal surface to break or compress materials. Mining operations use crushers, commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Typically, crushing stages are followed by milling stages if the materials needs to be further reduced.
The Crusher machine Include Jaw crusher,Mobile crusher,Cone crusher,Vertical shaft impactors .

Stone crusher industry is an important industrial sector in the country engaged in producing crushed stone used as raw material for various construction activities such as construction of roads, bridges, buildings and canals. The stone crushing units can be seen in the vicinity of almost all major cities and towns. The mined stone is transported to the crusher sites by road through tractor trolleys or pay-loaders. The pay-loaders unload the mined stones into storage hoppers located at elevated levels of the crusher sites.

These stones are crushed in a Primary Crusher and sent to a vibratory screen. The oversize from the screen is sent for further size reduction in secondary and tertiary Crushers. From the secondary and/or tertiary Crushers, the crushed stones are sent for screening. In the screen, products of various sizes get separated which are stored in heaps. Movement of stones from crusher to screen to product piles is done through belt conveyors. The product is generally stored in open areas. A schematic of typical stone crusher units is given in sand
